So my Sapphire Nitro+ RX580 Limited Edition cards came in today, so I ran some benchmarks.

I first tried to find the highest error free memory clock for each memory strap and chose one that performs the best.
I followed this up by downclocking the core until the mining performance was noticeably affected if I'd gone further.
I then proceeded to reduce voltages as much as possible.

The trials and results can be found here:
https://drive.google.com/file/d/0B0CbyDF8Rhg5LS1CdldsUGs5OTQ/view?usp=sharing

I was able to achieve 29.3Mh/s at 77.5W as reported by MSI Afterburner and HWiNFO without any reported memory errors. After 1 hour, the card remained at 42 Celsius in a 72 Fahrenheit ambient room using only 40% fan speed. If power isnt an issue, the 1450 stock clock at 1.125V which can go higher would do great for dual-mining.

I have 6 more of these to play with, and I'm looking to reproduce these results. If anyone has any custom memory straps they'd like me to test just send me a PM (these use Samsung memory).

UPDATE:

After additional strap tweaking, I've gotten to 30.5Mh/s Eth. The card can dual mine 1450 Mh/s Dcr with no power limit, however by balancing power to hashrate, I get 1130 Mh/s Dcr (w/ 30.5 Mh/s Eth) @ 125W

UPDATE2:

The Nitro+ RX580 seems perfectly happy to run on just a single 8-pin power connector. However from my tests, this reduced hashrates by 1% and power consumption by 1% consistently The 1% drop seems to only have been temporary.

Any rom mods. Also what driver version?

it seems thse cards  are good for dual mining even the 570 seems to  do 28-29 mhs eth and 700-900 dcr from the benchmarks I have seen with the mem straps updated

thats close to double dual mode on the 480 and 470s , you should try pascal and Lbry coin as well as the dcri

with amd what you read on afterburner is not power consume to the wall. there are big differences..

not good results at all.
my power color red dragon rx480 8mb is doing 30mhs@70w (gpu-z), sapphire ref-like rx470 is doing 28.8@73w (gpu-z) - ethereum only mode

i get with the RX 470 Sapphire 8gb nitro + -> 28.0 - 28.6 @63w (gpu-z) - ethereum only mode -> 100 - 110 Watt from the Wall

which bios editor you used??, I used polaris bios editor 1.4.1 but it can't read memory strap entries for my Sapphire RX570 4G Nitro+

with no mods  and msi afterburner  i can do 29mb  at 68w gpu-z on a few of my msi rx 480 8gb

if I use sapphire trixx I can get -125 mv on a few cards stable.

I mix it with  msi after burner  set clocks at 1150 and 2220



look the new cards are basically the same as the old ones

rx 470 = rx 570
rx 480 = rx 580

So what ever you can find at a good price get.

I used this fork which seems to work:
https://github.com/jaschaknack/PolarisBiosEditor

thanks it works, sapphire rx470-4g has two kind of memory? memory strap shows 1:xxxx and 2:yyyy

That is true - and it will MUCH easier to sell rx 580. So transition to new series is must

they dual mine at double the speed of the 400 series they are not the same cards at all

One is for Samsung memory and one is for Micron memory, only one of those sets of straps affect your timings. I believe the 1:xxxx is the Samsung straps by my tests

What are  the dual mine speeds? (stock and modded). All topics only mention ETH mining..

29mb... if you mean mh.. please provide pics.. I don't think that is possible without a bios mod!

I've been continuing to tweak and also optimizing for dual mining.

So far:

Eth: 30.5 Mh/s
Dcr: 1130 MH/s
VDDC: 0.877
Core: 1300
Mem: 2100
Mem voltage: 0.9
Strap: Custom mix
Mem Errors: 0/min
Power: 125W

NOTE: If you don't undervolt/limit power, it easily dual mines 30.5 MH/s + 1450 MH/s Dcr

very usefull info!.. if i take a 480 to the same numbers 1300 clock - 2100 mem, can i get the same Mh ?

Yes, I can corroborate this as I have MSI RX580's with Samsung memory and had to use the 1:xxxx straps. I also seen a video with cards using Micron memory where the guy had to use to 2:xxxx, so I think the  1: is for Samsung and 2: is for Micron theory is correct.

what software can i use to change the core volt and mem volt?

I don't run my cards on win 7 with claymore any more.

I do smos  give me a minute to set up a miner.

This is true, I got similar results as the OP, but my at-the-wall draw per card (6 rig system) was 108 watts after subtracting the PSU efficiency 92% and system idle draw of 50 watts. My GPU-z fluctuates around 80-85 watts, so I think the end results would be similar.

EDIT: To clarify I am getting 30 Mh/s per card (180 rig total) with core clocks set at 1135 and memory clocks set to 2275, core voltage set to 925 mv, memory voltage left at default. I did do the bios mod using the jaschaknack (sp?) PolarisBiosEditor by copying the 1750 memory strap (Samsung memory) from 1:1750 to 1:2000. I did try to copy the lower 1625 strap, but the system was unstable.

For full disclosure, I am also using the Crimson ReLive Edition 17.4.3 drivers on a Windows 10 64 bit system. Bonus, at least with the RX580 I did not have to apply the pixel patch after modding the BIOS.

My raw power usage data is:
Total rig draw: 760W (kill-a-watt reading)
PSU 92% efficient (8% inefficient):  760 - 60.8 = 699.2W (or just 760*0.92).
System idle draw (50 watts): 700 - 50 = 650W
Draw per card: 650 / 6 = ~108W

If you use Claymore you can use -cclock, -mclock, -cvddc, and -mvddc parameters when you launch the miner. See the Readme file in the Claymore directory for usage information.

Since Wattool seems to not read values correctly on the newer cards, I been using the miner directly to control the clocks and voltages, GPU-z seems to confirm it is working as intended.

1. can you run RX 570/580 and bios mod cards using Win 7 instead of win 10? In am tired of win 10 and would like to try 7 if possible.

2. Does anybody know if all those Win 7 pro codes that UK people are selling on ebay are any good and can be activated reliably?
(prices are between $6 and $9)

very usefull info!.. if i take a 480 to the same numbers 1300 clock - 2100 mem, can i get the same Mh ?
[/quote]

It has the same number of compute units/cores/architecture, so mostly yes, with a 480 you'll probably need much more voltage/power to achieve the same core clock however, and the memory has to be tuned beyond just setting the clock

I would say - an excellent results!

Did you buy $279 version on Newegg?

Yep thats the one

I made a few more changes, namely I reduced the cvddc setting a bit more to 900 mv and decreased the core clocks from 1135 down to 1125 and was able to shave a bit more off my power consumption, which is closer to 102 watt/card now. I also tried Claymore 9.1 using -asm 1 and -dcri 8 and I can get 30.5 Mh/s per card solo mining with the above power draws. If I try dual mining with Decred my wattage shoots up past 120-125 watt/card.

I got an interesting result testing. The Nitro+ RX580 seems perfectly happy to run on just a single 8-pin power connector. However from my tests, this reduced hashrates by 1% and power consumption by 1% consistently The 1% drop seems to only have been temporary.

here are my numbers :
rx 480 4gb
ETH: 30.3 mh
DCR: 1030 mh
clock 1250
mem 2100
107W afterburner
temp 65~

i cannot go furter because the themp will jump and surpass the 75º at 100% fan :S

Thanks for answering my question. That looks way better as the 480's

This is the news i've been waiting for, thanks a lot for sharing.
Im geting 12 Nitro+ to play with :)

I hate using 2xPSU on my rigs, and mostly have EVGA G2 1300w, which without adapters cant connect 6x6+8 pin.

Great news indeed  8)

@Apneal can you post a link to the Uber-mix v2.3 please, i dont understand, it is a app? i want to custom my timings

http://www.overclock.net/t/1604567/polaris-bios-editing-rx5xx-rx4xx

That's where the "uber timings" come from.

could you please share your gpu brand + memory type and your bios mod?

Never understood why people buy the 480/580 for a $100 premium when you can pick up the 470/570 for 170-180 and it hashes the same.

Well, if you're carrying RX 480's or 470's, you'll be feeling good to know that RX 580 are not better than RX 480 for mining. ;D

I personally don't want any new GPU to come up with huge hash rate upgrade and de-value my current rigs.

I would go for whatever is the cheapest deal personally. The 570s and 580s are priced about the same as the 470s and 480s, at least in the USA. I think if the price is within 10% I'd get the 500 series just for a little better resale value and possibly slightly higher hashrate (equal at least).

Why arent you using this:

Add a dinky low wattage power supply to power the the rest

I am a newbie when it comes to clocking and stuff but I am willing to learn. Are those settings you can set in watttool?

did you set the timings straps to 2000 ? or just OC ? or both of them

Wow ! This is a power beast ! Really makes me want to buy some to play with. Any idea about the other dual mining options ? I would be particularly interested in SIA and LBRY.

limited edition nitro is expensive as fok tho :(

Yeah, its 310eur here in Europe.
And the normal Nitro+ 580 8GB is crap, the memory is really bad with these first batches, slower than the cheap 570 4GB cards.

wonder if the cheap HIS Radeon RX 570 IceQ X² OC, 4GB GDDR5 are any good , they are only 190€

Its more about future resell value. If I'm squeaking out an extra 1Mh/s Eth and 250MH/s Dcr, it offsets about $125/yr, and the card itself would sell for $50 more later

Oh so these great performances come from the fact that this is a limited edition... Sadly, since I prefer picking many cheap cards, I think I will not opt for this one...

Here in Canada sometimes I see price for RX480 4GB ref as low as $240, it's even cheaper than most RX470.

I nabbed a few of those and they are all samsung memory.

Could you share your claymore settings for dual mining?

They have higher resale value.

Besides that, higher stock clock = higher stable undervolted clock = more dualmining hash

I appreciate the OP's post that is sharing with us the results, but one thing that I can't understand are the prices in newegg of these graphic cards.

570 costs much cheaper than 470 while it gives almos the same hashrate, same with 580=480

"The invisible hand" (c) A. Smith

Probably this cheap 570 has a shittiest memory type and ASIC quality of 60%?

hello sir ,,
I'm a bit surprised ,, RX 580 vs rx 480 why different mh/s a little ..
i see in range price far enough ,,
i see my friend in his facebook use rx 480 nitro get 30Mh/s .
so i shocker when i see rx 580 get 30.5Mh/s ..

€343,49 where I live..  >:(. Anyone any experience with the Sapphire PULSE Radeon 8GD5. That one is priced €275,-

I haven't seen anything in this thread that is that great - 108 watts is the best and that is mining Eth Only - or with DCR at an 8 setting Dual mining with 125 watts/GPU

There are plenty of sub 100 watt roms to mine ETH on 480's.  ???

The rest of the measurements are using software that DOES NOT measure the power usage of the card, only the actual GPU die

Do the pcie cables come with one of those? that combo looks awesome.. I've usually just got the evga 1300w

On my 480s I use about -dcri 25 and dcri 20 for my 470s... this is with the new v9.2.. values were about 5 higher with the old version

This only has the PCI-E connections, you would still need a PSU, that can power the risers aswell

There's PCI-E powered risers, but yes you'd still need a low wattage normal PSU with it, overall cost is down, and efficiency is up.

I see that it has only 8 PCI-E slots, but for six cards you'r gonna need a total of 12 slots.

If you dont want to use splitters I suppose, but I fail to see the point considering you need a normal PSU anyways.


I did some more power testing. The power draw per card from the wall (measured by plugging both the riser and the 8 pin power into a dedicated 94% eff power supply and multiplying the reading by .94)

Is 138W (eth only, 0.84V). 50W of this is from the PCI riser!

pci slots can draw up to 75 wats , even if your card was plugged into the board mo riser

it would still draw close to identical wattage frome the slot

What drivers are you guys using for the 570 with the mod ROM?  Any issues with RELIVE due to MOD roms?

Can someone share edited rom for RX 580?

This may be old news but did you guys know there are two versions of polaris 20, XTX and XTR?

from what i saw in articles is that the xtx is the 580 and the xtl is the 570...

There are 580's with XTX and XTR chips, XTR ones are more or less handpicked with lower default voltage and higher clocks. This is all we know so far, this is undocumented feature.

I'm using the leaked press release drivers because I'm having issues with the newest drivers on Claymore
http://forums.guru3d.com/showthread.php?p=5420996

Wow that's interesting. I wonder if gpuz shows which chip you have.. and if like all gpus of a certain model (like for example msi 570 4gb armor) are all the same "chip type"

Some cards with XTR chip:

MSI Radeon RX 580 Gaming X+
Asus ROG Strix Radeon RX 580 TOP
Aorus Radeon RX580 XTR
Sapphire Nitro+
XFX GTR­-S Black Edition

Anyone got a list of which 5xx cards use samsung memory?

or is the sapphire 580 8gb nitro LE the only one?

EDIT:

seems that the LE version can be hynix too... what a minefield.

anyone tried mixing a RX 480 with the RX 580 and run with mining?

How much reduces timelife of GPU when you biosmod it?

Also you've a picture of Dualmining? Just for P0rn  :D

How the hell can you guys mine that high with such a low power consumption ?!

My MSI 580 Gaming X is pulling 28 mh/s + 1100mh/s DCR and it takes around 200watts

Would anyone want to give me an overclocking lesson? I guess it could be very usefull and I could pay for it...

I never have do Biosmod but i see that is something with Power Limit + Core Clock + Core Voltage. Look at youtube (It's free)

Undervolting the piss out of your card, and balancing how much performance you're willing to give up.

Consider:
1MH/s ETH = 30W
10MH/s DCR = 6W
(obviously these figures change and are dependent on your local electricity prices, but is a good guide)

What this means is that if you sacrifice less than 1MH/s Eth and save 30W, you're profiting. So if you clock down to 1100mhz lets say and dual mine 27mh/s and 1000mh/s DCR, but this lets you drop your core coltage down to 0.8 and you now only pull 150watts, you're profiting (and extending the life of the card)

Can you post the custom timings string? These of course are the same chips as before some optimum strings have already been found, but I like this one due to only needing 2100 MHz :) Very nice target to get 30.5 MHs

Can use http://doreymills.ca/cgi-bin/strapmod?555000000000000022CC1C00AD515A3EC0570E142D4A64080049C700030114207A8900A00300000 0150E2A3186272E16

just plug in your own 1500, 1625, or 1750

custom timings (but public available, not private, private even better I think)
rx480 is clocked 1170/2050, rx470 1100/1980. voltage 0.88-0.9. Very stable and happy ))
and the queen - sapphire nitro+ 480 8gb samsung 1170/2200@0.88 @ 80w gpu-z 31.5mhs eth

Only for samsung or all others work too?

All work. I use 1750 modded in the tool for samsung, 1625 modded in the tool for hynix.. and elpida can be iffy so 1625 on the higher clocking elpida and 1500 on the lower elpida

(I used to use 1500 for hynix but im getting better results with the modded 1625 now)

I will now try my micron mix on that.

Micron refused to hash anything with the strap mod  :-\ Without the strap mod I am getting 29.3 at 2075 MHz

Its Samsung memory using Uber Mix straps from the Polaris Bios Editing main thread (google).

On that doreymills page there is no readme info guide how to exactly use it :(
Useless

It may not be designed for newbs. I didn't design it but I find it easy and very useful. Like I said earlier you plug (copy) the strap you wanna mod into the tool (overwrite the default strap in the URL) and use the modded strap (the bottom of the 2 on the output page)

I am no newbie. I do always thinks after study documentation, to know exactly what am I doing and why. You did not write and no one told exactly what that tool/site really does under the hood. "Copy straps", which exactly, what is the reason? What does this tool change?
I am sad that there is so much people who just simply don't really want to help. They just wanna show how big kings they are and inside they glad their rigs are running better then others.

I knew exactly how to use this tool immediately after he posted a link, because just by looking at the main page it basically says how to use it. You may want to go read the Polaris Bios Editor thread and get an idea of what straps are and memory timings and what this is trying to do.

I have modded lots of bioses, I know about straps and yes, I have read all 270+ pages about Polaris bios editor. There is just a blank page on the main page of the link, no info, no doc, so how can I know what it is exactly doing?  Maybe you have some other link...
I think for example "555000000000000022CC1C00AD515A3EC0570E142D4A640800400700030114207A8900A00300000%10span%20style=" with the span style at the end is definatelly not a valid strap...

If you want help you are welcome to PM me

Its a valid strap followed by some character codes for HTML. If you KNOW thats not part of the strap, why are you leaving it in? Remove the fluff, people shouldnt have to walk you through simple stuff at this level, and if they do then you should act like you need help and not act like tools which people took time out of their lives to make (which are valuable) aren't good enough for you.

Anyone have an idea why the micron card refuses this strap mod? Currently I am running a mix of 1625 and 1750 for last 8 pairs.

The strap mod worked pretty good for Samsung. I think I prefer it over the ubermix.

Not sure, Micron might just be unstable at those timings. See what it changes, and then try something in between?

All I wanted was just to know how this works, because there is no documentation. I was interested in it. And what I got? Only hatefull answers. Ok...
Yes, you're right. Sorry, I'm not so big King Kong as you are and I do not deserve any help. I not belong to your elite club. Enjoy your highness...

Go around and call other people's hard work "useless", and then the community who supports developers like this will keep it useless for you. Go sit in a corner and think about it.

I got my powercolor Red Devils (https://www.mindfactory.de/product_info.php/8GB-PowerColor-Radeon-RX-580-Red-Devil-Aktiv-PCIe-3-0-x16--Retail-_1167702.html ) in the mail yesterday and installed everything. They are now happily dual mining at ETC 24mh /s PASC 479 MH/s. I am not into modding bios'es yet. Would anyone be interested in tuning my cards. I'd happily take offers in PM  :) 

I never called other people's hard work "useless"! Keep calm macho...

Ì am about to pull my hair out. I have RX 580 with samsung memory but what I do it seems like my hashrate only goes down. At stock they do 24MH/s ETH / 480MH/s PASC.

This is my card in stock;
https://s18.postimg.org/rqfbyvcft/RX580_GPUZ.gif
https://s2.postimg.org/qg62x22sp/RX580_GPUZSENSORS.gif


I copied the straps from 1750 to 2000. So far so good and the hashrate remains pretty much unchanged. When I change the core clock to whatever value my hashrate only goes down. What the heck do I do wrong? I follow https://www.youtube.com/watch?v=FT9K8DqaeDs to the letter but only bad results.. Can anyone help me?

Your card is ~250w from the wall, you need to undervolt it!

Well the idea was to tune the hashrate first, the power consumption after.. Unless undervolting is part of the tuning to get the max hashrate?

Might have missed it in this thread but just to confirm: UberMix v3.1 strap mod copied over all straps above 1500 for your Sapphire ?

Cheers

What dcri value do you use to get these hashrates?

Apneal / Truthchanter

Thanks to you both for all the useful information, only recently got back into GPU mining and I seem to have forgotten everything I used to know and lots of things are new :)

Fired up my old 7950's that had been gathering dust and I got some new MSI RX580 Gaming X 8Gb cards and they come with Samsung Memory.

All I have done so far is copy the 1:1750 strap to the 1:2000 strap, currently using -cclock 1135 -cvddc 975 -mclock 2150 and getting much better results than stock of around 30MH and 100w per card ETH mining only, the problem I am having is when I try to dual mine with decred. My numbers go to pot, the ETH mining speed drops significantly to around 28MH even when the DCR speeds are much lower than yours around 600.

Could either of you share your claymore command lines to see if I am doing anything obviously wrong.

Also that doreymills site that was linked earlier, my original 1:1750 strap is
and it gives me

Do I copy the new one to both the 1:1750 and 1:2000 or just one of them, or do I do the 1:1750 then use the tool on the 1:2000 and get a new value for that too ?

TIA

My guy. How in the hell do you get claymore commands to work. It crashes my rig. One of my rigs i got it to work. i have several identical builds and for some reason something is blocking or taking control of the clocks and won't let claymore change the clocks or volts without crashing. Like bad crashes too.. hard locks. video artifacts.

what am i missing here.. I've been trying to figure out why i can't use claymore commands on any of my builds for over a year. But one rig does work. i'm lost. please help

i try even just -cclock 1250

You don't have to have all 3  cclock mclock and the volts set?

Regarding doreymills: Yes, you can to copy the new one to both 1:1750 and 1:2000. I think it will give you about 0.5-1 mhs extra speed.

Try a lower -dcri like 21 or so

Anybody tried the gigabyte AORUS cards? are they good, hashing and cooling wise?

are still profitable mining with gpu card?

I know people had issues with RX570/580 and 7 cards.

Are people able to run with 7 or 8?

Powercolor RX 580 red Devils are hashing at 26MH stock for me...760 DCR.....have not gotten into the Bios just yet....normally thats out of my realm...MSI afterburner only...

Also on another note....i have some old R9 290Xs hashing at 27Mh as well.....just using afterburner....

Where is the best place to track down the Bios mods?

Could you please share your rom for Nitro+ RX 580 8gb? I am only get 28.2 MH/s ETH + 450 MH/s Decred.
I use 1,100 core and 2020 Memory.

Regaards,

Try 1150/2100.

Hi all,
I got six RX580 nitro+ 8gb gpus.

I am complete newb tuning wise.

What should I do?

Should I use windows (7?10?) or ubuntu?


What miner?
Which pool is the best? solo or pool mining for this hashrate power?

Where can I find bios modded for mining to flash cards?

which software you use to tune them?

Any help would be appreciated if you have time to help me out
 

Hey all, I'm planning on building 3rigs with 6 Sapphire rx580 nitro + on each rig.
Any idea on which bios mod / driver I should be using ? The goal is 30mh eth rate per card

Ya but when I dual mine eth/dcr my kill a watt reads 1400 watts at wall with 6 rx 480's. Anyone else using this much wattage? My psu is a evga 1300, so as a result of this I only mine eth.

Sorry if I missed it, but what is your custom mix of straps?

Hello, I am quite new to the mining. I have been mining since nov 2016 with a rx480 for 8 months now with an xfx 480 that I run @ 1263 core and 2175 mem.
Got ~27 mhs from it.

I just bought an xfx gtr-s 580 and tried to overclock the memory.
I don't know if I just got a crapy manufactured memory chip set for this card  :-\, but here is the details.

GPU-Z:
Mem clock: 2000
Memory Controller Load: ~84%


Eth mining ~22.4 mhs !!!


GPU-z:
Mem clock: 2005-2160
Memory Controller Load: ~54%

Eth mining ~18 mhs

Once I try to overclock the mem the perf goes down.

The mem info from GPU-Z is
entry 1:
gddr5
autodetect

entry 2:
gddr5
Samsung
K4G80325FB

entry 3:
gddr5
Hynix (wtf)
H5GQ8H24MJR

I would have expected the same brand for the mem. Someone have the same situation with the same card?

Yes! I'm having this issue as well.  I tried all sorts of timing mods and the only one that seemed to work and was stable was 2:1750 -> 2:2000.  I'm still under 25 MH/s with dual mining, and no matter what overclocking I do on the memory, it drops...  Would love if someone could help here.

I'm using Gigabyte RX580 8G Gaming with Samsung memory.

You may use my specs and adjust accordingly, maybe it was not so good but at least it's a good place to start. It takes few days for me to found sweetspot for my card.

Ignore the temp as it is enclosed in CPU chassis without enough ventilation, I am waiting for Scythe fan to arrive to blow the heat away.

Using Uber-Mix Extreme v3.1 from OC.net


You may try using your own timing from 1:1750 and paste it to 1:2000 , result should be similar.

MSI Afterburner :

-96 mV core voltage limit
+30% Power Limit (well I guess this doesn't help but I just put it in)
1192-1198 MHz core clock
2075-2085 MHz memory clock

If you think that the core clock is not important for ETH mining, then you are dead wrong. So don't set the core clock too low either.

For Claymore configuration : use -asm 1 and -dcri 33 , i seen much improvement on compared to the screenshot above with ETH on 30.4MHs and DCR on 1000MHs

Good luck and if you think my post is helpful, feel free to donate some ETH/DCR for me!

ETH : 0x2345988e664AB0b2608185578623c5f252a40a17

Your power draw is very high man.. lower gpu clock, and reset power limit.

Yup, I'm in exactly the same boat.  Looking at the memory timings, as well, and they look completely off from all the tutorials I've ready.  Almost like they're not registering correctly with Polaris.  Anybody have any idea what's going on here?  Are the XFX RX580s from Best Buy garbage for mining?

I have a question about the HP 1200W Power Supply and the x5 breakout when using whit a normal power supply. When I start the pc, the HP supply starting automatic? I don't need a start button for the HP supply?

HP 1200W and Corsair RM650x is enough for 6 * RX 580?

Or only on PSU Seasonic Prime Gold 1200W?

Quick question everyone. I fortunately managed to get my hands on 2 Sapphire Nitro+ Rx 580 8Gb Limited Editions. I noticed the bios switch on these were already pointed forwards, in the position where we put it to reflash the bios. Anyone else notice this? I haven't set these ones up yet, still waiting for other parts. I'm thinking because they are limited edition models that perhaps they've already cranked the timing from the factory hence why the bios switches are already pointed towards the end where the hdmi/dvi inputs are. Anyone else have these?

That button on the breakout board is most definitely the power switch. As far as I can see the circuit does not have any components to automatically switch on the PSU which means you have to somehow manually do it.

I just short out the signal ports on server PSUs to turn them on but you need to know or find by trial the channels you need to short out (although using a resistor is possibly a better idea). Sometimes there are several of them, i.e one for the turn-on signal and one for the there-is-no-fault signal.

And, HP 1200W PSU alone should be enough to power 6 GPUs. You can run it at 100% load 24h no problem. It's a real 1200 Watt workhorse. IF you're on 220V utility, that is.

Hello Guys, I have a MSI rx580 gaming x and ASUS rx580 strix, both are samsung memory and both are 8gb. I am unable to push them over 27MH/s no matter what I do. This is the first time I am modding the BIOS so not sure I did everything right. I tried to copy the 1:1500 values to 1625, 1750 and 2000 for the MSI card and it crashes all the time, but works if I copy the 1750 values to 2000, the power draw is about 130 watts in GPU-z. Is there anything different I can try for this card?

For my ASUS card it only has the 0:xxxx values in BIOS and no 1:xxxx or 2:xxxx values. I copied the 1750 values to 2000 and I get 26 - 27 MH/s with 140 watt power draw.

Please help me get more out of them. thanks

Hello guys, I Have 3 Sapphire RX580 Nitro + 4GB (23mh/s stock), with Hynix memory. I have change the options (Copy 1:1500 to 1:1625, 1:1750, 1:2000 and the 2:1500 to 2:1625, 2:1750, 2:2000), but again, 24mh/s.. Only modified the Power Draw (155 to 132w).. Pls, anything option I change to work with 28~30mh/s? Thanks!!!

can you give me complete hardware details?
i planning build one
thanks

Performance timings! Those copy straps are bad!

I have Gigabyte RX 580 Gaming 8G Hynix on Windows 7
22.3Mh/s at stock (1340MHz 2000MHz 1.15V 122W)
As soon as I modify the memory clock the hashrate drops to 20Mh/s
I strap at 1750 (not stable at 1625), I obtain 24.9Mh/s at stock and at 1000MHz 2000MHz 0.85V 74W
No memory clock possible without a hashrate's drop.

I'm new in tuning AMD Bios and read a lot. I have a new Pulse RX580 4G D5(Sapphire type 11265-09-20G). The SRBPolaristools shows me that there are 2 different 4GB-VRAM types - 1st is a  EDW4032BABG (Micron-Elpida), 2nd is a H5GC4H24AJR (Hynix). Now occur the 1st question - why is that a 4GB only card and no 8GB card? ...and which VRAM should be adjusted for tuning - both or the Hynix only. Saw in some videos adjusting sometimes only the 1st memory and sometimes the 2nd memory, but never both. Thanks in advance for some helpful hints.

If I'm not mistaken, I think you go by the memory type that is displayed under the "Graphics Card" tab under Memory Type in GPU-Z
At least that's what all the tutorial videos I've seen have said.

Use GPU-Z, it will tell you what you have. Edit only the one you have. In my signature is tutorial how detect the memory vendor.

Thanks for the hints so far - I'll do so. Keep you up to date.

So, checked some RAM-Timings - some improvements after patching reached, but not higher than 27,2Mh/s. Better than the original Bios, but not 30Mh/s. On average the Elpidas RAM is slower than Hynix or Samsung - could be the reason. Open for ideas or suggestions to get the last 10% out. Thanks.
Update: I tried several Straps, but no selection pushed speed above 27,2. At the end I decreased the Mem-voltage to 925mV/GPU to 865mV - with success in power consumption without loosing speed. Core: 1150 and Mem: 2060. This was the best setup after a lot of tests.

Nobody any reaction on this - is that the end.....

how u make 29 mhs with 77 wats ? this what i read u stip clock what u mind u coppy from 1500 to all other up or what ? .. can u please explain this ? i will use this card to mine eth single so if u can help reduce power

77W in Afterbuner is nothing, it can be a lot less...

Got a RX570 nitro+ 4GB some days ago. Strange - has the same VRAM-Types - one Elpidas and one Hynix like RX580.But Hynix, instead of the RX580 Pulse 4GB, has the Hynix as the main VRAM relevant for tuning. I optimized successfully the BIOS by trying several straps - found the right one at the end. Got 29.8 MH/s - quite good, but only with the Glaymore miner under W10 and BIOS parameters: 1150GPU/2060Mem/0.9V Mem/0.86GPU. Power consumption @90-100W. With Ethos-OS I got only 26.5MH/s - anybody an idea why? If any questions - just ask for.

@Mattthev - sure that your ETH-Wallet-ID is correct, seems 3 digits are missing

If you don't mind, where did you get the RX570 nitro+ from?

got the last one, sorry. It seems that we all have to buy expensive cards either in the 2nd market like ebay or wait til AMD can produce more. Nobody knows actually when the availability will be better as long as a lot of new guys or companies join into the mining area. 

Right thanks. I accidentally delete it while editing my signature :D

welcome

Thank you

Thanks to everyone who has contributed to this thread!

I'm looking for help in getting my 2 XFX RX 580 GB Hynix to hashing > 30 Mhs.  I'm close and getting a consistent 29-29.5, but never go above 29.5.  I've made the following changes:

GlobalCore 1200
GlobalMem 2175
GlobalPowerTune 3
Globalminer Claymore (9.7)

Modded the GPU Rom to copy the 1750 Mhz Timing setting to the 2000 Mhz setting.

I've seen several instances of people getting over 30  Mhs with this card.  How can I get that last 1 Mhs?

My numbers are based on single mining ETH.

TIA.

Hi, I just flashed my shappire rx580 nitro+ 4gb oc. I just put 1:1500 timmings to 1:2000 and 2:1500 to 2:2000.

Result mining was the same. 24 mh/s. Im looking how to get best results with hynix memory but I dont find how. Any guide or any help? Thanks

What are you mining?  Have you made any changes to the clock / memory settings?

I have literally spent days on this... I ordered 60 RX 580 Nitro+ 8GB GPUs over a month ago. The first round of them started showing up this week (First two that I tested with are Hynix mem). Out of the box I was getting 24Mh/s. Updated drivers and was getting 21Mh/s. I spent hours and hours looking for info on how to get my hash up and was getting no-where. I had a min panic attack but then came across the below post.

http://1stminingrig.com/best-bios-rom-sapphire-nitro-rx-580-8gb-oc-hynix-memory-30-mhs/

User Ti posted down in the comments how they got it up around 30Mh/s (Real Solution). I did what was suggested and was getting about 28-29Mh/s. I just like you wanted that extra 1Mh/s as that plus 60 GPUs is a big deal. I tweaked and tweak in TriXX and below is how I am currently getting in the upper 30 and even 31 on occation Mh/s

GPU Clock: 1275
Mem Clock: 2300
GPU Voltage: -66mV

for the most part it seems stable but only been running for like an hour. I'll post back if anything changes. Good Luck!

EDIT: Once I started hooking up more than one GPU to the rig it would crash. Getting VM_CONTEXT1PROTECTION_FAULT_ADDR while trying to mine on SMOS. In Windows 10 once I would plug in the 2nd GPU the first would hash 1-2 Mh/s below the norm and the 2nd GPU was hashing at 4Mh/s total. There is something wrong with running these cards in windows 10. I've tried driver version 17.1.1, 17.4.3, 17.4.4 and 17.7.1 and all react the same. If I don't have an HDMI plugged into the card running a monitor the Sapphire LED goes off after boot and I can't get any temps or readouts. If I start mining with it the LED comes on but I can't see any temp/fan read out in Claymore and it gets very hot. Overall just very glitchy and unreliable in Win10. Why would running 2 GPUs cause this? Any ideas?

Right now I have it stable for about an hour in SMOS (ETH 29Mh/s - SC 585Mh/s) but I had to reflash the bios and remove all undervolting. Just have copied mem straps as suggested in the link above. Only downer is that each card is pulling 180W as before with the undervolt it was under 100W.

If anyone has successfully got these running (6 or 8 gpus) on a rig and stable around 30Mh/s I would really like to know the secret magical settings. Any help would be very much appreciated.

How I can lower the vcore in PBE? I know that 65xxx values are dynamical for support all cards so how I can to decrease vcore then?

I read a lot and check a lot of bios and only values changed are mhz, sometimes go high as default and sometimes are lower.

Thanks

Hello
It does not let me go down more than 100mV, so I do not go under 1025.
I have copied your settings and it goes very well, but with the mV at 1030.
How do you lower it?

thank you very much

Ive been trying to setup my rig for dual mining
Its running 6x XFX RX 580 GTS XXX (Hynix)

I've edited the memstraps already

Cant seem to get more than 500 MHash on Decred on dual mining

I am getting 29.4 Mh (Eth) and 540Mh (Decred/Sia)

Claymore settings are


cclock 1150
mclock 2190
cvddc 850
mvddc 950
powlim -20
dcri 19

Even at stock voltages I cant seem to push the cclock any higher without it crashing.
My understanding is the cclock affects the decred mining hashrates.

GPUZ is showing an average 115v

i'm modding HYNIX and samsung rx 580 8GB and RX 480/470
to get best temps/power cous/ hashrate

up to 30.6XX~ stable without errors modding 20$ each card, if you're interested please Send a PM

thats great results, good job man

there asint no way people are getting 29-30mh.
i have a sapphire nitro+ rx 580  8gb speacial edition only got 26mh copied 1500mhz all the way up and set memory clock to 1900 as was crashing at 2000mhz anymore pointers expecialy on reducing power

if i offset the mv to 975 or do i have to change the max wattage output?

also do i need visual redistribution files 2012 or 2013 installed?
i have amd drivers 17.7.1

help please get more out my card i flashed it

now i go to launch the ati flash utility it says error reading from rom?

Dear all, would like to post my findings about power consumptions - I use RX580 with 4GB - the normal polaris and one 570 nitro. I'm measuring the whole power consumption of a rig. The board with cpu is consuming about 60W. A whole rig with 2 RX580 and the 570 consumes about 500W - this means a power consumtion of 150W per RX. With the tuned RX580 I get 28Mh/s and with the tunded RX570 nitro+ about 27Mh/s. I expected more from the nitro+ (has Hynix), but I checked several stripes - no way to get more out. Think experts like matttev can get the last percents out, but I don't think it's possible with only 80W per RX580. It all depends on how to measure the power consumption - it's easy to get wrong on that.  

what should i change to reduce the wattage the gpu uses since i know have my memory OC and my gpu core underclocked. am using srbpolaris is a value for tdp but also a value for max power limit and small power limit? or if its the VDDC i should change what is a good vddc for a 1100mhz core on a rx580 an rx480

I'm using the voltage values recommended by 1stminingrig when I downloaded the rom from there and it's been working like a charm for 90w, I haven't done any further customisation but it can be a good starting point for you

http://1stminingrig.com/best-bios-rom-sapphire-nitro-rx-580-8gb-oc-hynix-memory-30-mhs/

Do not waste your time with Windows. This system is only for small rigs.

 I have 27 rx580 8G Nitro hynix, 3 rigs with 9 gpus each. Only works with Ethos. I've spent weeks of testing and more testing. (Ethos is a big shit but only works steadily at 30MH in this SO)

The Saphire rx580 8G Nitro also seemed to me the best cost benefit, but that's not what I'm seeing. It is low cost but only for ETH mining.

I have another rig with 7 Nvidia 1070 Gaming X worked perfectly in double mining with 31Mh ETH and 310Mh SC without having to change the bios or overclock, running Windows 10

Update: I discovered that all Linux-based systems (Simpleming and Ethos) can not do undervolt on AMDs, so going back to Windows with limited GPU, 8 by rig.

what undervolty worked for you mine seems to crash when i undervolt it around 100 and 50 where is stable shows no watt difference

Have you guys tried the new AMD Beta driver just released specifically for Mining?
I got my MSI RX580 Armor 8GB with hynix memory (flashed with modded VBIOS - 1750 straps copied to 2000)

With Epoch 139 now my card was down to 28.3MH/s. With the new driver I am getting 30.5MH/s

I found that after installing the driver do not patch the driver.
Use AB 4.4.0 beta 16
The undervolting does not work well for AB, but i used Global Wattman that installs with the driver, Set Voltage manually to 990mV but it didnt work, so changed it back to Automatically. After that it applied the 990mV correctly.
So the ADL API is very buggy with the new driver but the driver definately solves the hasrate drop on Polaris. (Do not specify the clocks or voltage in claymore miner as it does not work)
AB sets the Clocks fine, it's just the voltage that is a bit of a problem.

GPUcore is 1250, Mem 2200.

I need help? help when it comes to undervolting my system when dual mining.

I have 6 Red Devil Golden Sample Edition cards, i am using claymore 9.7, afterburner beta 16

My issue is when i am single mining #Eth i can undervolt via afterburner to the lowest settings which 950 (ish) and system follows this settings.

When i am dual mining without setting afterburner to limit voltage, my system uses up about 1450w, so i try to limit voltage to 950/1100/1300 and none of them are respected. i am a little stuck on why this is and just seek my help from those who are having this issue.

Is it really that much more  work to set voltage in vbios.

Not really, as long as your mining software will read it - which is not the case for Claymore 9.8 + AMD blockchain drivers.

I've set mine via SRB but Claymore ignores it. Ended up setting core voltages via Trixx and it's working like a charm.

HI

Can anyone tell me what hash rate i can expect from the below?

https://www.asus.com/uk/Graphics-Cards/DUAL-RX580-O4G/

Will i need a custom bios? If so which one? With a custom bios what hash rate can i expect? What power usage should i expect per card?

I bought 8, but only want to use a single 1200watt power supply. So guessing i may not be able to run all 8 cards?

Also, in my NVIDIA Rigs ive been using a specially designed Nvidia linux image to run the rigs.

What am i best running on this new RX580 Rig?  Windows? Or is there a dedicated AMD Linux image i could work with?

As much info as possible please!

Thanks in advance.

Can anyone tell me what hash rate i can expect from the below?

https://www.asus.com/uk/Graphics-Cards/DUAL-RX580-O4G/ All of my Dual OC 580s (8gb) are Samsung.

Will i need a custom bios?Yes if you want a better hashrate
If so which one? You can buy mine, or do trial-and-error yourself
With a custom bios what hash rate can i expect? With my 8GB, I do 29.3 ETH plus 733 DCR
What power usage should i expect per card? Mine pulls 160w at the wall

I bought 8, but only want to use a single 1200watt power supply. So guessing i may not be able to run all 8 cards? GPUs rull full power upon start up, so no. Even undervolted, you'd need 1300w at least. I use 2x 750w.

Also, in my NVIDIA Rigs ive been using a specially designed Nvidia linux image to run the rigs.

What am i best running on this new RX580 Rig?  Windows? Windows 10 would be the easiest.
Or is there a dedicated AMD Linux image i could work with? If you know Linux, I suggest going that route. If not stick with Win10.

As much info as possible please! One side says it's not profitable to even think of starting to build a rig nowadays. The other side says you can mine other coins if ETH goes south.

Thanks in advance.

Hi Guys,

thank you for your time and help.
After installed the fresh Win10, I downloaded the rom what Brockshad suggest and now its very good. The miner is dual mode (ETH and LBC), ETH is fix 29.7, LBC is 91Mh/s. Its really good. In only ETH mode is 30.4.  :D
Its under test in dual mode.

Core cl.: 1130, Mem cl.: 2150, the voltage 850-850.

I check GPU-Z, the "GPU only Power Draw" is 105W in dual mode. BUT from wall 216. What does it mean, why its so hight? What do you think? Maybe my computer need so lot of volt extra?


My other question, maybe you have a solution: before the fresh Win install I received a lot of "video scheduler internal error" and blue screen. I'm looking for solution, this is vor VGA driver, I must to update it. ...but this beta driver direct for [Suspicious link removed]puting is okay for me.
What do you think?

Is there any difference in Hashrate of mining ETH based coins like Ubiq and musicoin ( with low size dag ) and Original ETH? ( using RX 580 )

I've mined various Ethash coins and the hashrate, as far as I could tell, did not change between the different coins.
Give it a go for yourself and see what happens, it should only take a few minutes to test it out.

Quick question. What is the use of bios modding the card, if you can set extra launch parameters in Claymore? Don't these override the former?

Its not the same thing...you can change frequency in Claymore, but you can't change TIMINGS

Recently setup 8x Nitro+ Rx 580 4gb with various clocks ranging from 2025 up to 2100, but only has a single core clock of 1200 across. Mvddc and cvddc are set to 875mV. Right now it is pulling ~1320w at the wall and pushing a total of 244Mh/s eth and 6.1Gh/z dcr.

All's nice and shiny BUT it gives me random openCL errors across all cards!  :(

Sometimes after 4 hrs GPU1 will hang, sometimes after 5 hrs GPU6 will do the same. I can't put my finger on it why it is happening but I know it is not a hardware issue as I've changed, replaced risers, usb cables, x1 connector, pcie ports, pcie 8-pin cable - the whole laundry list of things you can change but still no avail. Note that when a GPU gives out openCL error and hangs, it's only a single GPU that hangs and not two or three or more.

I'm on Day 6 now and it is still restarting.

One thing to note too is that I almost have zero, as in ZERO memory errors across all GPUs. And when I say almost, I mean one or two GPUs have about 20-30 errors in a span of 3-4hrs, so it's nothing and I know it's not enough for them to crash it. Interesting fact too is that the GPU/s that has some memory errors on them aren't the ones crashing.

Could it be the 1200 mem clock? Could it be it needs more than 875mV of voltage? I'm almost out of options here. I need help.

Thoughts?

I think you are pushing your cards too hard. I found my RX580's were very touchy about overclocking/undervolting too much (they had modded BIOS's).
I also found that after overclocking the card(s) needed to be run for several hours to check for stability.

Nah, it turns out it’s a driver issue.

Updated to win10 FCU last night then installed 17.10.3 driver then boom! issue gone.

Been running 15+ hrs straight now without no hiccups or dropping cards.

After this stability run, i’d push them to 31 again.

I beg to differ. The older RX 470/480 series cards consume LESS POWER. This is a known fact (based on specs on boxes) and one that i myself have tested at the wall with a power meter. The additional 1-2 hash rates are nice but if electricity is a big factor in your profit (mining in places where electricity is expensive), it will be best to stick with the old cards.

Resale value is a small matter. If you're mining you should be in this for the long term. Mine until your GPUs die.

You might get a bit more out of the cards if you install the AMD blockchain drivers. There are two version of the drivers, the latest is only a fix for Vega cards, but both will work with RX580's.
http://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-Crimson-ReLive-Edition-Beta-for-Blockchain-Compute-Release-Notes.aspx

EDIT: Oops ! see you are already using the blockchain drivers.

I used to but I updated to 17.10.3 and set the cards to "compute" settings. I don't see any difference of using this driver VS the blockchain one, except this new one fixed my OpenCL issues.

I have 8 RX 580 only get 16.8 setup on Claymore`s more clock 1125. Clock 2090 any help please

Hi guys,

i´m really new in this, so i hope you guys can help with some qualitive information and your expierence about gpu settings in mining ETH.

I´m using right now Claymore Dual Miner/ just mining eth only on dwarfpool

Components:

 850w EVGA + h110 pro btc motherboard + 8 bg ram (hyper x fury) and 2 Gpu´s Sapphire RX 580 Nitro + 8 GB.

My stats:

constant 341 watts total (think the motherboard is using 90 watts and the cards using 125watts each)
core clock 1250
memory clock 2250
voltage set to 900
and a powerstage on level 3 (using simplemining)

Fan Speed 40% and a temperature of 49% on both cards. They are bios modded btw.

Results: 31.35 MH/s with every gpu / total of 62.70 Mh/s

Everything is working stable, but i don´t know really if i decrease the life span to much with this settings. I know that life span is decreased generally by mining.

I really wan´t to have the best long term settings, like 2 years and more. Maybe you can tell me what really decrease life span. Is it only the temperature and voltage that get involved in this topic?

Does core clock and memory setting not reduce life time? And what do you say about my settings.

What expierence did you made?

I know: a lot of questions.

I appreciate all of your answers which getting me more in touch with this issue.

Sincerely yours,

miningenthusiast

Congratulations for you 30+
Mine only gets 18 + and can't find any help here good luck to you
I think if you keep your Gpu in lower temp it's will be good for a long time

Hello,  anyone could help with this RX580 4GB (Hynix) in order to got 30.5 MHs ?

I am getting right now 29.0 MHs  with  1300 Core - 2100 Mem

https://i.imgur.com/swc3CaO.png

Have you tried Polaris Bios Editor https://github.com/jaschaknack/PolarisBiosEditor or the variant SRBPolaris Bios Editor https://bitcointalk.org/index.php?topic=1882656.0

Or see if any of these BIOS's will help https://anorak.tech/c/downloads/xfx

Hello,

Can you tell us which model it is ? Gigabyte ? MSI ?

You need to know that 4Gb models are less efficient tan 8Gb models : you should already be happy to reach 29MHs :) I think you should stop here

(my RX 580 4gb does not even reach 29MHs)

This guy doesn't know what he's saying  ;D

If you do, then explain why i'm getting these:

8x Sapphire Nitro+ Rx580 4GB Elpida

Ahah, thank you guys for your feedback :P  I'm sure I read that on other forums... I'm quite curious then ! I'll try to O/C my card better

Can you share your BIOS here ? My Gigabyte RX 580 also has 4Gb  Elpida memory, you'd be super nice :)

Thanks a lot !

Guys, i have a question. When you flash the bios on 6 cards that are in the same rig, how do you do it?
Do you remove them all and start one by one. Do you flash them when they are on the raisers? Or you have to insert them in the mobo?
I always remove them all and do it one by one, plugged to the mobo without raisers.

The safest way is one by one without risers, directly on the motherboard

That is what I do, one card at a time. I have a spare PC and mod the BIOS's on that PC, this lets me test how the mod went and to check if copying straps or using some pre-configured BIOS or the 'One Click' option on Polaris Bios Editor gives the best results.

hello to everyone!

im newbie mining coins. I have 13 GPUs rig, the GPUs are Asus dual RX580 8gb and im using EthOS. Can you help me with some questions?

1) By default im getting 24,4 Mh/s, how do you reach 29?
2) I dont want to mod the bios, so, what do you thing is the best setting that I can do on Core Clock, Mem Clock and Voltage



Thank you all!!!

I'm afraid without modding the bios this hashrate cant be achieved.
I did not want to mod my cards either, but i found out that this was impossible otherwise.

Hello, another noob here,  8) 8)

I'm using 1 Shappire RX 580 Nitro+ 8gb with hynix memory. I just modded the bios

this are my numbers:

260W ish from the wall
mining etherium at 31.8mh/s.
1250mhz on the core
2250mhz on the memory
around 100W for the gpu core
fan speed at 30% around 57ºC for a 24hours period.
-175mV on the core
from 949 to 955mV while hashing.

am i doing the things right? Thanks for your help.

I have big problem with my RX580 8g msi I get only 18K how come?

I have 2 cars the RX550 does 9k

driver is 1.7.7

any help ?

That is a good speed you getting there. You should go more in depth for us or even create a video. That is a very good speed and I doubt better is even possible.

Can someone please help, I have these card, MSI RX 580 ARMOR 8GB OC with Samsung memory, I copied straps 1:1750 to 1:2000 and 2:1750 to 2:2000, that pushed my stock hash from 19 to 24.5, haven't overclocked as yet. Hash rate still low though, it could be very helpful if someone knowledgeable can help.

Here is my original rom: https://mega.nz/#!jdxDnBRL!kJokqryH6FtSMfQiyIlovZxmTUcqRlgYzVjvmK_3Rts

Thanks

Here are a couple of things you can try.
Use Polaris Bios Editor and select the 'one click' option for memory timings https://github.com/jaschaknack/PolarisBiosEditor, or try a pre-configure BIOS from here https://anorak.tech/t/anoraks-vbios-collection-optimized-settings-for-performance-power-saving/13

I put the beta drivers and now does 23k it's ok for me

Anybody can confirm the rx580 can be plugged with only one 8-pin connector ? I hope I could add a second one on a 520W power supply.

Theoretically you can get away with only the 8 pin connector if you don't over stress the card.
There is a good article on GPU power .. http://www.overclock.net/a/gpu-and-cpu-power-connections

Apneal said in the very first post that it ran fine with one connector, I have MSI cards which only have 1 plug anyway.

I will be setting up a system with a MSI RX 580 8GB in a few days. Your power consumption seems to be quite high compared to other figures i've seen on fora and youtube. Do you have this card in a complete system (so including other HDD's and a CPU with high TDP? I will be able to compare when my system is up. My rig will be headless and dedicated to mining though.

I still don't understand what are the best driver.. the blockchain one? That from august?
I have rx 570 4gb pulse itx and i get with bios mod 28mh eth+ 50mh lbc idk the power consumption from the wall
But how i can use less power drawing? Putting down the tdp? Or there is something else thing to do?

If you have newest Win 10 build use lastest AMD drivers with compute workload
http://support.amd.com/en-us/kb-articles/Pages/DH-024.aspx

Hello. Normally people just tell you the gpu core power consumption. Mine is around 100W as i said. The system on idle uses about 100W to the wall. My cpu is a Xeon X5460 with 120W TDP, but even at full load only uses 40W according to cpuID HWmonitor, (it's way voltage downcloacked from VID numbers) so , not bad at all for a 4 cores 4 threads 8 year old dinosaur.
Yes, i use my rig for daily (it was not meant to be for mining but it is indeed now). add an 120mm AIO, 3 x120mm fans, ddr3 1,65v and not the best efficient mobo (though a good old one, like it is the Asus P5QC) and two hard drives, one SSD and 1TB hard drive. also RGB lights on the case and high performance keyboard and mice with RGB lights.

But, you should know that there are more variables. For example, the Asic Quality determines how much voltage does the card need to use, and moreover, are better overclockers and downclockers aswell. The higher asic, the better, mine is "average" at 75%.
Another variable is the memory. It's said that Samsung memory use less power than mine (Hynix memory)so there you can get a few watts less.
Another variable is the slot. cards with risers use less power according to what i've seen. very little less, but when you have 6 cards, well, it can be like 20-40W less for the whole 6 cards.

The sapphire RX 580 pulse model, as from stock uses less power, you can go way down to 0,835v using 77W and hashing nearly 30mh/s. While mine, the Nitro+ uses more core voltage so the number from which you can downclock is higher than on the pulse, even at -200mv it will not let me go below 0.925v no matter if i go to 1000mhz on the core. So, in practice, for only mining, the pulse is the way to go. Thought i think you can tell the miner to insert a certain voltage, i haven't tried it out.   

for a complete 6 RX 580 8gb cards mining rig the total power consumption according to some people is about 850W to the wall. like 125W per card (assuming idle power consumption of about 100W)This is achivable just by going to 75-80W on the core power consumption.


I can confirm, that , with my settings above, i don't need to plug the 6 pin conector, it will be perfectly fine with the 8 pin connector while hashing. i've tried even 1450mhz on the core and 2250 on mem with just 6mv added to stock voltage on the core with only the 8 pin connector and it was perfectly stable in Uniengine Heaven and 3dmark fire strike, so....there you are.

according to my numbers, my card uses while hashing a total power consumption of about 150W, Being like 100W for the core and 50W for other components. I've tried going below that, but the savings on W are very little compairing with the Mh i do not get. 

My results:
Win10 + BlockChain Driver

1) 8 x MSI Armor RX580 8G Hynix
Clocks 1200/2080, V 900/905 - 29.2mH/s + 930mH/s @ 1420W from the wall

2) 8 x Sapphire Nitro+ RX580 8G Special Edition Hynix
Clocks 1200/2250, V 875/875 - 31.6mH/s + 920mH/s @ 1520W from the wall

With Ubuntu wasn't able to get even close to these numbers.

Hello guys! I bought Gigabyte EX 580 Aorus 8 gb memory:samsung. Can i use the BIOS from Hynix, example? Or where i can find BIOS for Samsung? Thx.

You are lucky you got Samsung. No Hynix won't work. Same place where you sax Hynix timings, search on this forum and overclockings.net, etc

I was wondering the same.  Which straps for Samsung?

I tried 1750 as suggested and it does not produce best results. Only 26 mh/s maximum.

For comparison my Hynix ones, with 1500 strap produce 28- 28.5 mhs.
Should I use 1500 strap for the Samsung too?

Check here: http://indeedminers.czechian.net/timings.html (http://indeedminers.czechian.net/timings.html) and make sure you have Blockchain Driver + Win10.

How profitable is RX580 nowadays? Let's say you are mining Monero, Ethereum, Verge.

Thank you hozerdev.

It depends on how much hashrate you can squeeze out of your RX580, which depends on the card manufacturer (e.g. XFX or Sapphire) and, significantly, the vRAM manufacturer (e.g. Hynix or Samsung).
You can get a good idea of the profitability of individual coins by using this web site http://whattomine.com/calculators use the 'GPU' tab to check multiple coins at the same time http://whattomine.com/coins

I had the same question of Intellecual Romanticist, and now i'm wondring which of XFX or Sapphire / Hynix or samsung is better ?

An other question, is there a real difference between RX480 and RX580, and between RX 570 and RX580 ? and finally 4Go and 8go ?

Thanks

I would recommend you sapphire of course but it's impossible to know if their memories will be hynix/elpida/samsung

Anyway sapphire nitro+ are the best cards actually in my opinion

There's no difference mining between rx 580 4gb or 8gb

Rx 480 are not for sale you just don't question about that :)

Between rx 580 and rx 570 the difference is a bit hashrate, I prefer rx 580

Any good miners for zcoin?

Thanks for your answer,

So, i think i will buy RX580 4Gb, it costs less :)

But in france we can buy RX480 ! has it any advantage ?

as far as I know, they will hash the same but at bit low power usage

Have installed 8 RX 580 4GB Nitro+ Elpida memory. 7/8 cards are getting around 30.5 mh/s @ 2050 mem and 1150 core. The last card I'm not able to get past 1900 mem..i can push a bit more with error and if I set 2000+ windows crash. It is the exact same card model with memory type etc as the other card all brand new with same serial also.

I thing I noticed is that dag creation ms is higher on this specific card.

Anyone seen this or cause it ?

Guys did you tried to benchmark it to other algo like ETN i was heard that there are some miners are getting more profitable mining ETN these with rx 570/580 base on what i search..
Also wanted to ask if whattomine is accurate if what altcoin is profitable to mine?

Thanks for your clarifaction. I somehow missed the 100W per card remark you made, I was comparing the 260w from the wall.

I finaly got my first card in and am playing around with the numbers. I'm in the 75-78W region in GPU-Z and 100W on a kill-a-watt meter. Now it's hashing stable at 28,7 Mh/s for 24 hours. This is with a modded bios (Samsung mem) with values from Uber-Mix 3.1. I'll be trying some more tuning.

I have powercolor rx580 red dragon which has both 8pin + 6pin connector and I only use 8pin for each of them no problem works fine. I just need to improve my hash rate on SMOS.

Unless you are short in PCIe to power everything, is there a point using only the 8pin instead of both ?

Hello, i have the same GPU with elpida and i can't get over than 1975 for memory wihout a freeze..

I made some overclocking with my cards :

1. RX 480 MSI ARMOR 4GB (samsung) 1100/2100 (few memory errrors HWINFO)
2. 2x RX 580 MSI Gaming X 8GB (Hynix) 1100/2000 ( no errors HWINFO )
3. 1x RX 580 MSI Armor 8GB (Hynix) 1100/2050 (no errors HWINFO)
4. 2x Sapphire Nitro + 8GB (Micron). 1075/2100 (no errors HWINFO) one uses 8+6 pin, the other one uses only 8 pin, because i was out of cables.

My Rig works on msi z97 Gaming 5 with 16GB Ram, 240GB Toshiba SSD and core i5 4460, and the power draw is Around 950-980 Watt from the wall for dual mining and about 800-820 Watt at ethereum mining.

My Hashrate for dual mining is around 172 mh/s and 5200 mh/s for Decred.
I'm using 1000W 80+ Bronze PSU With 500W 80+ bronze PSU to make it more stable.

All cards except RX 480 (925mv) works on 850 mv voltage. Even with some memmory errors on rx 480 it works fine, without crashing. MSI Gaming X are worst, because they arent going to get even 29mh/s at those settings.. I think there's no reason to going up with voltage to get 1mh/s more per card. Temps are very low, sometimes fans stops, because is lower than 55 celsius.

I'm using one click timing patch on all cards.
I was configurating that for around 10 hours to find best settings for them. I think that power draw around 1kw is good score. if u fave better setting for those cards, please reply :D

Greetings

i just help my friend tune his MSI  card which is the same as you. can go 30.6m with others strap. The first thing you would like to you is using ddu to uninstall the driver and install the blockchain driver.

I just bought a couple of RX580's.  Is it still possible to get these to run with Claymore under Linux?

It seems that the Linux software is too new for any driver software that I can get my hands on.
Drivers keep complaining that my Xorg is too new, or that dkms code cannot be installed because some structure member no longer exists in the kernel headers, etc. The only driver that installed fine, the amdgpu-pro-17.50-511655.tar.xz  and the AMD-APP-SDK 3, do not seem to be supported by Claymore.

Just having a tough time..
-turgut

Finaly got my card in. The same as mentioned above. MSI RX580 Armor 8GB Samsung. Now hashing without memory errors at 30.2 Mh/s and 650 Mh/s SAI. The memory straps improved the stock hashrate, but tuning the memory clock and GPU clock improved things from +/- 27 Mh/s up to the current values. Power usage is about 88 Watt GPU-z, +/- 110 Watt from the wall in dual mining mode.

Yes you can. I've tryed Ubuntu myself, but hash rate is down by 4 Mh/s. This is with the most recent mining driver from AMD. Also power usage is higher than on Windows and I can't overclock/undervolt. I would use Linux if the performance was a tie or even somewhat less (this is my first Windows install in years), but it just isn't worth it at the moment.

Can't get my MSI RX 580 8Gb Gaming X (samsung) working on voltages lower than 975mv. If try to go lower than -170 in afterburner, system hangs even in 2D.
Is it the limitations of AB or I'm rather unlucky with my card. Virtually every guide on the internet says you should be able to get them working with 900mV @1150 Core freq.

Update to my initial post.

Managed to downvolt to 875 with OverdriveNtool, just had to revert any changes done with AB. (Afterburner changes relative values not absolute, so the -170 in AB was way too low to go when OverdriveN settings were applied, also it seems Overdriven doesn't overwrite every AB settings).

Getting 30Mh + 86 Lbr @117W

hello
I have 13 x RX580 XFX GPU with Samsung memory.
I am using simplemining but I can't pass over 25Mh/s per card. I have not enough time to search and try different combinations.

So i can pay someone to give me the best choice: best bios and settings.

So I also got a Rig running with 7x Sapphire RX580 Nitro + 8GB
5x with Micron Mem and
2x with Samsung/Hynix [GPU1 and GPU5[ (why are 2 Mem's on one card?)
Windows 10
Blockchain Driver
PCIE0+PCIe1 Gen1

The bios for all gpus are patched with PolarisBiosEditor166 One-Click-Patch!
Read and written with newest WinAtiFlash.

The command line to start Claymore looks like this:
EthDcrMiner64.exe -epool eth-eu1.nanopool.org:9999 -ewal WALLET_ADDRESS.rig1/EMAIL -epsw x -dcoin sia -dpool stratum+tcp://sia-eu1.nanopool.org:7777 -dwal WALLET_ADDRESS/rig1/EMAIL -dpsw x -ftime 10 -dcri 20,20,20,20,20,20,20 -cclock 1200,1160,1200,1180,1160,1180,1200 -cvddc 875,885,875,880,885,885,875 -mclock 2150,2100,2150,2150,2120,2100,2150 -mvddc 875,885,875,875,885,889,875 -tt 57,57,57,57,57,57,57 -fanmin 42,42,42,42,42,42,42 -tstop 78,78,78,78,78,78,78

I get a complete Hashrate of 209MH/s ETH and 4150 MH/s SIA with a power consumtion of 1150W from the wall.
ETH: GPU0 30.355 Mh/s, GPU1 30.056 Mh/s, GPU2 30.396 Mh/s, GPU3 30.398 Mh/s, GPU4 29.679 Mh/s, GPU5 28.629 Mh/s, GPU6 30.388 Mh/s

The fans are running at around 50% and the temperatur of the GPUs is around 48-52°C so I think this is not bad at all.


I think I have to tweak the Core and Mem settings (clock and voltage) a little bit more, so I can decrease the power consumption maybe by 50W but I didn't think I get that RIG under 1100W.

There has been a sudden spurge of interest in the RX 580 too now. These too are not available anymore. So sad. I could manage to get my hands of 3 of these.
2 x Asus RX580 8GB (Hynix) ( and 1 x Sapphire Nitro RX 580 (Micron).
Sapphire Nitro is the workhorse absolutely. They are doing 29,29,30 ETH and total of 800 DCR at 430 Watt at the wall meter. I think I ca go higher with the dcri.

My question is regarding the fan temperatures. The temperatures are running at 65 with fans at 60-70. Are there any tweaks specific to fan speeds for better temperature management??
Its still winters in India and I can only imagine the difficulties that'll come with the summers.. :-\
Any suggestions on temperature management would be really cool.

Ok tell me how are You getting 30 Mh/s when I can just get 29.4 no matter how I clock it? I'm currently running on 1200/2000 at 981mV (on AB). Not using blockchain drivers but Crimson ReLive 17.11.4.

I have four 6 card rigs, all Sapphire Nitro+ 8gb (Samsung memory). After BIOS mod, I am getting 29.2 - 29.8 MH/s with all cards. Clock settings are as follows:

Core clock - 1130
Mem clock - 2200
Core voltage - (-125)
GPUZ - (96W-97W)
From the wall - (880W per rig)

Everything seems to be running smoothly with no rejected shares (so far), but while mining in ethermine.org, a lot of concern arises which are not included in discussions. I wanted to post a screenshot here, but couldn't find the option.

Reported hashrate - 714 MH/s
Current effective hashrate (ranges from) - 584 MH/s - 758 MH/s
Average effective hashrate - 674MH/s

Valid shares - (505 - 652)
Stale shares - (37 - 72)
Invalid shares - 0

My concerns are although my mods and clock settings are working fine, with no rejected shares,

* Why is my average effective hashrate 40 MH/s lower than than reported hashrate?
* Why am I getting 8-10% stale shares?

I have tried nano pool, I was getting lower no. of valid shares per hour (about 120-135/rig) whereas at ethermine, its about (140-160/rig) and stale shares (9-15/rig).

Hi guys!
I downloaded the Radeon Software driver Crimson ReLive Edition Beta for [Suspicious link removed]pute Driver and got 29 mhs on my Sapphire rx 580 8Gb.
Previously, I had to change the bios timing settings for such performance.

Hello guys,

I have Nitro + 4GB and 8GB.
i have 30.5MH/s with ETH without HW ERROR.

But with Cast XMR in Cryptonight, i cannot have 900h/s like people, the best is 830...

What is your tune for this algo ?

I have this :

1150/850
2150/875

Hynix memory
and Elpida too.

You seriously using this parameters?
1150/850
2150/875

Because 850mV for the core is quite low at this speed, also 875mV for the mem with 2150 is also quite low.
Are you sure you are not getting HW errors, I mean don't look at HWiNFO64 because it is not showing all errors.
I had also no errors with HWiNFO64 but the cards stopped working from time to time without showing some errors in the HWiNFO64  software.

I have error on 4GB model (elpida) but no on Hynix.
But you are right, it's probably low...


Where can i find good set for this model ?

Some cards can have 850mV at almost 1200MHz. 875mV for Samsung memory is not a problem and it's not actually memory voltage...

I bought two Saphire RX 580 Nitro+ 8GB  (standard, not limited edition) with Samsung memory. I have Windows 10 and installed drivers Beta for Blockchain Compute 23 Aug. Also, I modded strap in bios, -dcri 6, claymore 10.3. In MSI Afterburner 1100/2150 and my results are about 29.6 mh/s per card. Power consume from wall metter about 380 w. Can I get better results with same or lower power consume?

Hi everybody,

I need some guidance/advice. I got
- MoBo Asrock H110 Pro BTC+
- 8 GB Ram
- 128 GB SSD
- 6 x Sapphire RX580 8GB Nitro+ Special ed.
- 4 x MSI RX580 8GB Gaming OC
- 2 x 1200W PSU Corsair HX1200 (Platinum)
- 1 x 750W PSU Chieftec (Gold)
- Win10 64 up to date (latest version),  no antivirus
- ATI drivers 17.11.4 (setting "compute" on all cards (all cards properly recognized)

main 1200W PSU powers motherboard, CPU, PCI slots, SSD,  all 10 risers
secondary 1200W PSU powers 6 GPUS
third 750W PSU powers 4 GPUs

The BIOS of all GPUs is modified and the settings in Afterburner (or in my case TRIXX) are 1150 core, 2150 mem, - 132 core voltage.

Running cryptonight algorythm the hashrate per card is approx 710 h/s and total power consumption on full load from the wall is around 1230 Watt (monitor excluded) . System running very stable.

However when I fire up Claymore with Ethash algo hashrate per card is approx 32 and full load on the wall jumps up to approx 1450 watt and system shuts down with a clack and reboots....

I have tried connecting the GPUs to different PSUs but no change. Cryptonite always stable and no matter what configuration Claymore shuts down my system as soon as full load is reached.

I can't be a question of lack of power because my PSUs provide more than enough juice for the whole system. Any ideas or hints would be greatly appreciated.

I would guess - not enough power to properly run the GPUs at max load.
Cryptonight uses less power vs ETH.  That may explain why it works on Cryptonight without issues.

Yes, you may have 3000 Watss in total PSU power, but you also have a nice mish-mash by that mix of few PSUs and 10 GPUs.

For starters try MB+ few raisers + few GPUs on the same 1200 PSU.   Do some math, leave 20% free capacity.  
The rest on the second 1200 PSU , and may be 2 GPUs + raisers on the 3rd smaller PSU.
Check how much each GPU consumes on max, etc.  Eventually you can figure it out and be careful.

Can you split the usage numbers per item. What part of the 380 w is going to the cards (total minus CPU, MOBO, HDD, etc. devided by two)? What does GPU-Z say? I think 380 totaal is on the high side and could be +/- 60-100 w less. What kind of PSU are you using?

Apneal, Can you send me a private message please?
I'm not able to because I'm a "newbie" on this forum.

We spoke together in the past, Thanks!

Hi guys. I have this RIG:
6x 580 Nitro+ 8GB Hynix
Asrock H100 Pro BTC+
Using a custom BIOS. Concrete modded my original "silent" bios with Polaris 1.6.6 with "1 click" metod. For OC and undervolt using "OverdriveNTool"

Using Adrenaline drivers.

Have 180 mh/s

1- 1200/900 y 2100/900 - ASIC 66.8% - 0 memory errors

2- 1200/900 y 2150/900 - ASIC 72.8% - 0 memory errors

3- 1200/900 y 2100/900 - ASIC 74.6% - 0 memory errors

4- 1200/900 y 2150/900 - ASIC 79.4% - 0 memory errors but today have "Hangs in OpenCL call" the other days i can tested no errors in some hours

5- 1200/900 y 2100/925 - ASIC 68.6% - 0 memory errors but today have "Hangs in OpenCL call" the other days i can tested no errors in some hours

6- 1200/900 y 2100/950 - ASIC 79.5% - 0 memory errors. This GPU always have "Hangs in OpenCL call". In few days i will recieved a new riser to try. Yesterday and today no Hangs.... I am very confused

Max time mining without errors is 10 hours... I try for 2 months config this rig, i desperate..

Try with the AUG drivers the beta.

Can you try this miner for cryptonight to check how many you have https://bitcointalk.org/index.php?topic=2256917.1540

1. Update Win10 fully to FCU.
2. Trash any other OC software.
3. Upgrade (or downgrade) to AMD 17.10.3
4. Use Claymore v10 and set all clocks and voltages there.
5. Profit

Note:
-this assumes you know how to set GPUs to compute
-don’t forget to use PBE v1.6 to mod
-don’t forget to use ati patcher

hello.

actually i have 2 Sapphire RX 580 Nitro + 8gb running (a third MSI RX 580 Gaming X 8gb is coming on monday (it's was a bargain considering prices nowadays). Just a few tips for those that read this.

Afaik 850mv on the core is just about "right" in many scenarios. both of my cards cannot stay up with that voltage for a long time. Moreover, it happens to me than whenever my internet fails, the cards hang. Why? Because the voltage offset actually afects iddle voltage so, if the card uses let's say 100 on idle, if the internet hangs, the miner stops, the cards tries to go to 300 mhz on the core, and than the offset is applied so 100 minus offset = crash.

According to my findings, my cards can run for more than 50 hours (damm temperature hang error) with 880mv on the core at 1240mhz. The memory (Hynix and Micron) at just fine at 2250mhz without any issues at all. My micron card is perfectly fine at 2250mhz on the memory at 865mv (i modded that on the bios, no issues). For the hynix, i have it at 900mv (also modded). Stock setting for that card was 1000mv.

With DCRI 10 those 2 cards are actually hashing at 32.1mh/s. Both are using like 88W on the core and 60 for the other components, so around 150W total GPU power consumption. Solo mining. it's possible to reduce power consumption by undervolting (also reducing core speed), but my excel tells me that it's better to use a bit more Watts and squeeze the best out of it, because usually more hash rate is better than too much undervolting.

Just to clarify the numbers i'm talking about. For a reduction from 880mv to 856mv on the core, in case you are worried about electricity,  you just save around 6W every hour.  also ASIC quality is important, both of them are at 75% but if you win the silicon lottery maybe you can go way down undervolting. The best thing of this, is that once you know exactly what to modify in the bios , it's easy to get what you want.

My best advice, (if the cards are going to go for mining only), is to test them with certain settings, make sure they are stable, and then put that config into the bios, so that you don't have to apply manually the settings using MSI Afterburner.

I install 17.10.3, no OC Software and Claymore 10, get more errors with same OC and undervolt settings.


I use original "Silent" BIOS editing by Polaris 1.6.4. Only editing the timmings by "1 click" method.

To OC and undervolt i use OverdriveNTool

I`m still new and only this week after 3 boards have a set up that im playing with

i have the following:

open air rig
6x sapphire rx580 8gb with hynix ram
4gb fury ddr 4 ram
asrock h100 btc+ board
1600 watts psu
sata type red risers
4 x 12cm led fans

i have each card on the following

1150/850mv 2150/850mv

pulled over 180mh/s

watts 970


still doing some settings as get a few gpu errors/watchdog so learning

Interesting. Where do you measure these watts? Software or at the wall? I've got 2 rigs mixed with rx480&rx580's and they are so power hungry. Yours seems to draw under 160w/card.

If its single mining ETH, why now...even lower.

Hello, guys.

I'm having issues with my 6 RX 580 Nitro+. The problem is the last few days I started getting "GPU hangs in OpenCL call" error. I did lower the clocks and I wasn't getting errors in HWiNFO64, but the "GPU hangs in OpenCL call" error still occured today, even without getting GPU errors.

Do you guys have any idea what else can cause the issue?

Had the same issue yesterday. One gpu tilted a little bit in the PCIE port (slot) because of the heavy heatsink. After fixing it worked again.

https://image.ibb.co/dcOQgw/IMG_E6253.jpg

this is with all the rig and usb mouse and keyboard

at card, look here from techhpower gpu

https://image.ibb.co/c2DDZG/IMG_6298.jpg

pulling 181mh/s

https://image.ibb.co/jGdrMw/IMG_6299.jpg

yes they are 150-160watts out of the box, but you haven't modded them? when i stated i was 1480 watts at wall , i then got to 1100 or so with small mods

https://image.ibb.co/cV5SuG/RBNB5445.jpg

i have been told on anoak site, i should be around 880watts, with 31mh/s but the guy has not got back to me yet with the bios

I've got that too, but it seems intermittend. Sometimes it goes for days without it and sometimes i've got it a couple of times a day. A reboot fixes it, also without any errors. It has been sugested that it can be triggerd by using a VNC server to access your Windows host, but I can't confirm that myself.

WOW! That's how it should look! I bet you are running Windows?
Your figures, how does one read those: "1150/850mv 2150/850mv"  First looks like clock speed and the second voltage. Is the first pair coreclock and the second pair memory? Sorry for my noob questions :)

Do you use PolarisEditor to hack bios or something like Trixx or Afterburner to do it on the fly?
I'm using Linux so I have to set everything up in Windows using Polaris Editor and then move to the Linux rig.
Megahash works OK, I get around 29Mh/s but it seems quite hard to get the watt usage down when the card sits in the linux box. Can't figure out how the same bios can act so differently.

yes gurgelkoff.

1150/850mv 2150/850mv
core clock/ voltage for core clock then  mem clock /voltage for mem

thats pretty much it.

Well, after the last "GPU hangs in OpenCL call", I did the opposite this time, kept the clocks pretty much the same, but lowered the voltages a lot(to about 860) and now I'm getting 180 mh/s and the rig has been stable for 2 days now. I do get some CPU errors in HWiNFO64, but as I said, everything has been very stable. This doesn't really make sense to me, but it seems to work for now. However, after I get home I will check all the risers and maybe re-install the drivers.

Edit: I got the "GPU hangs in OpenCL call" last night. Can somebody please advise me what should I do in this situation?

Start with default memory clocks first then add 25 when stable until you crash again. Dial back down then that’s your sweet spot. You should do this to all cards individually as no card has the same ASIC quality.

Guys, is there any way to separate memory controller and gpu voltage? I would like to set for example GPU core voltage @880 [mV] and Memory Contorler Voltage @950 [mV]. But no matter what I try, it is always like the lowest GPU voltage I can achieve is the Voltage set by Memory Controller. In this example GPU@880 and Memory@950 result in both @950 mV. Is there any way to fix this in PBE, or it is impossible or require more difficult BIOS mod?

Simplest way is with Claymore miner, just use the options -cvddc 880 -mvddc 950

Oh man - did You even bother to read what I just wrote? If I set -cvddc 880 -mvddc 950, Vcore would be 950 anyway. It is somehow "linked". cvddc can not be lower than mvddc. If You do not believe me, check it by yourself. Lot of ppl thinks that their GPUS works on very low voltage, becasue they didn't bother to check it. It also does not matter if U use voltage control @: claymore, trixxxx, afterburner, wattool etc. :(

did you try with fixed numbers from bios mod?

I tried, but it does not work too.

I got the same problem.

If i change using Msiafterburner or even OverdriveNtoll, i can efectevely change the core clock voltage.

If i see HWINFO64 i see my core goes to 0.94v  but after a while he returns to 1.063 for example..

Anyideia what should i look?

I got an

Asrock H110 PRO BTC
120gb SSD
8GB Ram
 CPU G4400
1 Saphire 8gb NItro + 7 Shaphire 4gb Nitro
2 EVGA 750 watts GQ
Windows 10


Thanks :)

HWInfo is very nasty tool. I did notice, it is able to cause issues to miners when restarted (to be more specific, if you restart miner while running HWInfo). Incorrect voltage, wrong clocks, memory erros or slow hashrate - only OS reboot fixes the problem. Also be sure You use only one tool at time to control clocks/voltages, for example if You use Claymore to control voltages, uninstal Afterburner because they can interfere each other.

Hi,

I doned all you recommend but the problem persist, perhaps how can i check if correct voltage is being aplicated in my core?

I use cast_xmr-vega to mine.

Reagrds

You can use gpuz

Hello, I have not found hash information or bios of the sapphire rx570 pulse 8gb, 4gb if there is information. Some help?

Hi,

Thanks for help people :)

I use this tool too. But the voltage that i choose in P7 stage in Overdrivetool is applied but only 1 or 2 minutes. After that an other voltage is automatically selected. Could be a bug in blockchaindrivers?

I tried to lock all P2 - P7 stages but the voltage only works momenteneos and if i change the clock too.. Very strange.. Maybe im doing something wrong...

Hi, sorry for quoting after long time, but I need some help. I will have in couple of days 3xXFX RX 580 GTS XXX 8gb, so I am wondering what PSU are you using, i have one of 1000 watts, but not sure if this gonna be enough.
Hope you will answer.....

Thanks in advance.

Hey, new miner also. Mining for 3 weeks allready have 11 sapphire nitro special edition 8gb. Stable 30.2 MH without modding bios. Dont have power meter, but seems my cards taken lot of electricify on globalpowertune 5. Trying to set 3. Stable for few hours now. How much mh i can reach if i flash bios? I'm useing core 1250, mem 2290 on ethos

i have 580 8gb gigabyte with hynix memory and 1 sapphire with micron memory, in wattman my max memory setting is 2250 (wich i m running on), how can other ppl set memory higher?

Afterburner app maybe? I so something on YouTube. I didn't try it, this is  just suggestion.

my settings in wattman reseted while running the miner lol, i guess 2250 is too high (950 default mv). wth

I received two of 8 Nitro 580 8gb cards this week and one has samsung memory and one has hynix. Used pbe v1.6 one-click patching and set the clocks to 1200/2100/875.

Hynix can only do 30 Mh but the samsung does 30.8 but with a mem clock of 2090, as it’s crashing with 2100 setting.

Should be allright. I'm running three cards (RX580) on a 650 Platinum without any trouble. The uptake isn't that high.

i will be getting 8 of these cards next week and I’m excited as heck!

can you try modding the bios via polaris bios edition v1.6.7 and use one-click patching?

Try setting core to 1200 and memory clock to 2200 or 2250 whichever is stable and if could report back, that’d be awesome.

Just saw you use ethOS but if you have access to Win10 to bios mod, that’s super!

Hi guys.

I have bought a Sapphire RX 580 8GB with Hynix memory.
After some tweaking arrived at the mirific 30 Mh but for a small amount of time (2 to 3 hours and then "crash").
I' ve configured my card with a Bios mod, running at 92 Watts, 66º Celsius degrees and 28 Mh stable for more than a week (24/7 work).
Did anyone get better hash values with this amount of watts consumed and temperature?



Share your findings.

Thanks. ;)

So I was racking by brains out since I only recently had a setup of Vega cards and sold some of them to switch over to 580's. I was getting a great hash rate from the V64 and V56 so I thought switching over to the 580 would be easy. After two days of getting nothing but 20.X no matter what I did I finally got my Sapphire RX580 to be hashing at 31.9X.

I almost was ready to burn down the world because I couldn't get higher than 20 no matter what I did. There's so much information out there that's out of date and so many different tools and I was going crazy.

In the end, ran DDU, only had 1 card installed, bios mod only the memory strap, and used overdriveNTool to do the rest and when I started up Claymore I'm at 31.XX.

What a relief and I'm happy now that I'm in the 30's club on an RX580.

(BTW, my card had Micron memory... unlucky me but it seems that it doesn't matter what memory really.)

Now to start testing tomorrow on the MSI RX580 cards and see if I can replicate the same hashrate.

I took a photo of this so people wouldn't call me a lier.

All 5 gpu are MSI Armour RX580 8GB

All have exactly the same OC, BIOS mod

The 2 with Micron mem are running ~29.8 MH/S

The rest have the Hinex mem running ~27.8 MH/S

But this 1 freak cpu with Hinex is somehow running at 45.5 MH/S @48C

Alas it wasn't meant to be, it only lasted 10 min before Claymore reset itself and the freak went back to its old self. lol

You have OCed too much. It's not so unusuall with Claymore, but it won't last long.
You more likely need better timings.

Thats just it, I didn't. The OC settings are the same on all 5 GPUs across the board. 1130 Core, 2200 Mem. Undervolt to 850 on core and mem.
I have since then lowered the mem clock down to 2150, as this seems to be the most stable for this type of GPU.

The hash rate reported by Claymore seems flaky at times. I can started once and it will report 24.5 to 27.5 MH/S, just stopping and restarting the miner will change the hash rate to 27.5 to 29.5.

may be you hit a claymore bug in the "hashrate" increase function  ;D
anyway..on restart it should be ok.

The clack is when a PSU port line OCP is overloaded and shuts down to protect the circuitry. With the balanced wiring you should be able to run you rig with two PSUs only. How are your risers connected to the PSU? Hint: Connect the risers to the 8-pin ports (as many as you can). For the rest - when you run out of 8 port cables-empty ports on PSU) - connect to the 6-pin ports. Only connect max 2 risers per sata/molex cable.
Identify (User Manual) what are the individual ports max amperage values and make sure you are not chaining too much to the same port or port group.

Background: On my PSU (Corsair AX1500i) there are ten (10) 8-pin port connectors each protected by 40 A OCP and six 6-pin for SATA/peripheral protected all together by 40A OCP. So all 6 ports (6-pin) combined can  only sustain at max level 40 A. This can sustain up to 6 risers. Connecting 7th riser on this same set makes in my case exactly your behavior, which in my case happens in 10 minutes of running the miner, consistently.
When you connect your GPU to the risers and an 8 port power it will draw up to 75 W (about 5-6A). Connecting 10 risers, all to SATA ports would yield 60 A, combined.
In your case I guess you are combining 10 risers to the 6-pin PSU ports via SATA-molex cables and so pulling too much power and the PSU is clacking it self down. This only happens at maximum load when you start mining at highest rate.

The occurrence of power shutdown when an PSU OCP is exceeded is harmful and can burn your components.

It doesn't matter what you set mem voltage (mvddc) to, it's always running at 1.6V.  To actually change mem voltage, you would have to muck around in the bios.  The setting, as you point out, acts as a floor for the core voltage (cvddc), though it's actual purpose escapes me.  I can only imagine that a.) it's a leftover of previous models which is actually no longer necessary, or b.) it's meant to be a sort of signal of the minimum core settings necessary to fully utilize the memory bandwidth available at that given clock setting.

Bottom line, just set it somewhere below your P7 core voltage, and everything will be fine.  In fact, I usually set it somewhere around my P4 core voltage, so I can fiddle w/ P7 while the miner is running and not worry about being limited by the memory voltage setting (which can only be adjusted while the miner is offline.)

Btw, I find OverdriveNTool much more straightforward for adjusting clocks/voltages than any of the branded tools.

Hi guys, can someone help me out? Im a noobie regarding mining and just started. Just built my rig yesterday and was running a first test to see if everything works. However my hashrates are devastating. Currently all the settings are orginal, so next step is to optimize my system (undervoltage / oc).

Running 6x Sapphire Nitro RX580, 8GB on a ASrock 110 pro. Everything is yet out of the box. System draws currently 1100w.
System: Windows 10 Pro 64bit, 1709
Driver: Crimson 17.11.4 Beta

Did run a "Quick Start" on https://nanopool.org/ for testingt. So far this are my results and funny thing, the two cards with 18mh/s are Micron chips and the other 4 are Hynix :D. So next goal is to join the 30mh/s club, is this tutorial still the way to achieve it? http://1stminingrig.com/best-windows-setup-configuration-tweaks-for-mining/ --> Tweaking Windows / flash the bios / oc the cards?

Did you set all cards to compute mode?
https://support.amd.com/PublishingImages/Support/KB/DH-024/DH-024-03.png
Also, why are you testing with this driver specifically? Imo it isn't worth it to download random bios from internets, much more right thing to do is mod bios by yourself (either using PBE 'one-click' or just testing with straps from 1750, then 1500 and so on), doing by one card.

think not, so increase windows virtual memory / set card to compute mode and flip the switch on the card? Open Gpu-z and ATI Winflash and save both files before modding. And modding should be done only with one card (removing the other 5), right? What I don't get, what's the difference between the Polaris Bios EditorSapphire Trixx and MSI Afterburner? Which one is the way to go?

Don't bother w/ compute mode until after you've updated the bios on all your cards - you'll want to reinstall drivers once all bios' have been updated.

PBE is for editing the bios (hence the name).  Trixx/Afterburner (as well as Wattman and OverdriveNTool) are for updating clocks/frequencies post install.  I use OverdriveNTool exclusively.

So... what would you choose between Samsung and Micron memory? (Sapphire nitro+ 8gb).

Depends on what you want to mine, and how proficient you are w/ strap editing.  Samsung does a little better for cryptonight using the best publicly available timings (a.k.a 'ubermix' -- ~1025H/s) vs the best available Micron timings (~1000H/s).  On the other hand, the best publicly available Micron straps are better for ethash (~33MH/s) vs the best available Samsung ones (~31.5MH/s), though if you can create your own custom straps, you should be able to get to 33MH/s w/ Samsung as well, according to certain people on these forums. 

Other coins/algos generally fall into one of these two camps, or are generally memory agnostic (like LUX/phi.)

Well it seems one of my PSUs had a knack and also my mobo suffered (partly melted PSU connector... So I got myself a new PSU (Corsair H1200) and a new MOBO (Asus B250 expert mining) and 4 additional cards (sapphire nitro+ SE).

However the MOBO can only address upto 13 similar cards (mine are all AMD RX580.

I have
PSU 1 (1200W) 4 x RX580 + MOBO and 4 risers + SSD
PSU 2 (1200W) 5 x RX580
PSU 3 (750W) 4 x RX50

Total power draw from the wall (incl monitor) is 1700 watt

Hashing power is around 390 mH/s with modded BIOS and OverdriveNTTool at 1150/875 and 2150/875

win10-64 with AMD drivers Jan 2018 and compute mode by AMD compute switcher. 8GB RAM 228 GB SSD with, 80 GB set temp memory.

Cards are
6 x Sapphire Nitro+ SE RX580 8GB GDDR5 Hynix
4 x Sapphire Nitro+ SE RX580 8GB GDDR5 Micron
4 x MSI Armor OC RX580 8 GB GDDR5 Hynix
All cards are between 29.50 and 30.50 mh/s

Problem is usually that  you don't know what memory you get as you can't  check the cards before you buy. But it does not matter in my opinion. I have 14 RX580 8GN cards with Hynix and Micron Memory and all are giving around 30 mh/s per card with modded BIOS.

I got modded VBIOS for my cards from fellow miners over at anorak.tech

You need a powermeter to determine your total consumption on the wall. It is not expensive.

I got 13 RX580 with mobo, SSD, monitor, etc, power draw from the wall around 1700W so I suspect 1 card will be around 110W on the wall... Without modded VBios this can jump up to 180 Watt and your cards will get HOT!

I've seen Newegg listing the mem mfg lately.

Thanks.
I could choose from the supplier. Hynix was the worst.

Have u tried adjusting gpu clock to 1250? That gave me much better result. (Dual mining)

I have configured 40+ GPUs achieving 30.0-31.9 on cards with 140-150W on wall per card on ETH only mining.
I use my own approach in dealing with the wiring/bios/modding/running Claymore and setting the undervolting/underclocking values for each card individually. Each card is different so it needs to be tuned individually.

As as see many newbies challenged with the setup I am offering my assistance to anyone willing to match my results.

If you are up for a test drive, I would be willing to help you tune your system directly to a similar results to mine (see below). Done this few times using Skype/TeamViewer - works great.

Hi guys,

I have an rx580 4gb gigabyte aorus with hynix memory, running on windows 10.

I made the oneclickpatch 1.6.7 two months ago.

0 Problems.

She is hashing in 860 - 880 range with this settings in afterburner:

950mv core
-10 powerlimit
coreclock 1150
memoryclock 2020mhz

Everything ok.

But today when i unintentionally click on reset functionatlity in afterburner, the card get 960hs.  8) 8) ???

So i think let me try to increase the freq of memory from 1750mhz to 1800 etc..

But changing up the memory clock doesnt increase anything..

And if i restart the amd gpu miner 11.2 with the default setting, the hash is not so high like was before restart,

It only increase if i toggle between my setting to default.

Could be a bug in miner?  (i tested in amd gpu miner and in cast xmr) Never happend to me.

So now i start with my settings, toggle to default and get more hash.. but...doesnt make anysense :) ???

I prefer v10.0 personally.

Are you with Windows OS?

if so check that it has updated, if so that is probably why, its killed 90% of peoples mining rigs on Windows 10. just need to do a PC Reset to an earlier build. Should work.

Hi,

Windows 10,

I blocked all the automatic updates. All my rigs run fine on windows 10 and in linux. :)

My question is just curiosity, if someone had have this bug too :)

I think its corellated with overclocking only...

What are the advantages from an older version 10.0 ?

Hi,

can someone explain me please how to U calculate the wattage of gpu in GPU-Z.
Like, do U have to add: GPU only Power Draw and VDDC Power Draw and VDDCI Power Draw, or what?

GPU-Z version 2.8.0

Hi guys,

i just uploaded an video of my problem on yotube:

Hi,
I recently got few of sapphire rx 580 nitro+ 4gb Samsung memory,
moded bios with Polaris 1.67, applied UBERMIX 3.1,
moded TDP from 145 to 120W, and Max Power Limit from 175 to 140W.
Got about 29,5mh/s at ETH.
What can mod next to rise MH/s and lower W from wall ? 
in Afterburner lowered Power limit -10 and control fan.
When rise mem to +100 got about 30.5mh/s but becomes unstable.

Regards

Samsung micron?

sapphire rx 580 nitro+ 4gb Samsung memory

hello Apneal, How did you test the memory straps? MSI Afterburner?

Wooh there little dawgie ! The original post was from almost a year ago, but anyway..
I used Afterburner to quickly test Memory Clock and Voltage settings to tweak my cards, you would also need HWinfo to check for "GPU memory errors", no errors are best, lots of errors are very bad.
Some people like to use OverdriveNtool instead of Afterburner.

From testing my msi rx580s with 8gb micron I found they consistently wanted a multiplier of 1.81 between core and memory clocks.  This worked from 1900 to 2270 on the memory. Go lower on core and you lose hash. Go higher and you don't gain anything.  Plus you're just wasting voltage.  I think the multiplier theory will work across all rx580s but it will be a different number for different memory.

Keep this in mind when fine tuning cards.  It will help save time.

Another quirk I've found is the higher of the chip and ram voltage is used for both. At least that's what HW reports. It is also about 0.025 lower than what you put in overdriventool. Or is it just my cards?

When they crash they usually reset to the stock bios core and ram speed. Keep that in mind when flashing the BIOS. But they always go to 950 mv on the ram.

Thanks! I test it in changing the config of claymore's start file...
I am confused by the mem errors reported by HWinfo, meanwhile there is no reject from the pool.
Using 1xSapphire Rx480 8G nitro+,with uber-mix timing 3.1.

runned 24hours with no reject but 1000 in total mem errors reported by HWinfo.

There isn't many differences in v10.0 and v11.4 for Eth mining only, except for stale shares. I find v10.0 has waay less stale shares than v11.4 for Eth mining only.

Hi just one question;

I followed instructions here
https://1stminingrig.com/best-bios-rom-sapphire-nitro-rx-580-8gb-oc-hynix-memory-30-mhs/
so
I leaved hardware in silent BIOS and modified with V1.
Core Clock 2130 MHz
Memory Clock 2175 MHz
Fan speed 69%.

So it mine ethereum on
31.18 Mh/s.

Should I change it from silent mod BIOS to turbo?

Anyone using ASUS Radeon RX 580 8GB Dual-fan OC Edition GDDR5?
I got a pretty good deal for this model but the thing is, I found different opinions someone says it is decent, someone says it has a bad cooling.
Any first hand experiences here? Someone mining with such? What are the temperature, clocks, and what algo are you mining whit it? Do you also have any other model to compare the Asus with it?
Thanks!

I have one and the cooling is totally fine. Pretty silent and while mining different cryptonight coins and ETH it sits at around 70°C max. So yeah, go for it. Good luck with memory vendor lottery :D

Hmm isn't 70 celsius kinda high?
I have MSI Armors and currently I mine Ethash with 31 Mhs and 59 celsuis. Undervolted and bios modded.
Thanks for the answer!

thank you for sharing but i saw 37Mh/s and 81W via youtube.com . i will try as soon as posible i hope good your bios mod. Thank you.

How the hell can you guys mine that high with such a low power consumption ?!

My MSI 580 Gaming X is pulling 28 mh/s + 1100mh/s DCR and it takes around 200watts

Would anyone want to give me an overclocking lesson? I guess it could be very usefull and I could pay for it...

First of all, you should stop dual mining, it doesn't make any sens anymore with decred asic, and you will increase your ETH hashrate while reducing A LOT your consumption. You can find plenty of nice tuto on this forum about overclocking. I have this one in mind : https://bitcointalk.org/index.php?topic=1954245.0 (https://bitcointalk.org/index.php?topic=1954245.0).

Hello.

I am currently running a rig of two Powercolor Red Dragon RX 580 8Gb's, one Powercolor R9 380X 4gb, and one XFX R9 380x 4gb using Window 10 Pro, Blockchain Driver August 23. XFX sits directly on mainboard, the other three on riser. RX 580 are using modded bios from Anorak.tech (https://anorak.tech/community/t/bios-request-powercolor-rx580-8gb-red-dragon-samsung/28052). Here are what I got:

Hash rate of 101 Mh/s (29.6 for RX 580, 21.4 for Powercolor R9 and 20.5 for XFX R9)
Power pulled from the wall is 880W which is very high.

Does any have good setting for Powercolor Red Dragon RX 580 to lower power consumption?

Thank you

I run my RX580 sapphire nitro+ special edition with modded bios from anoraktech at the foll values set by overdriventool

GPU 1175 mHz / 850 mV
MEM 2200 mHz / 850 mV

Hashrate per card 31.5 mh/s at approx 110w on the wall

Sorry, I don't have a solution for your question, but if low power consumption is important to you then try mining one of the Cryptonight variant coins, I found they take 25% to 30% less power to mine - and you can always then convert your Monero (or whatever) to Ethereum.

try this one -cvddc 850 -mvddc 830

RX 580 do not accept less than 850mv stable. almost all RX 580 will do 30mh except if memory are very low tier. the best for me are Micron by a huge lot. i have two MSI Gaming X 580 8gb with samsung memory, and they can't go past 2100mhz without having losts of errors. two micron are doing 2250 without erros. The rest are Hynix with variable results. I have 1 card doing 2050 at best. And other hynix doing 2250 without errors.

all RX 570 and 580 will pull from 120 to 140 if well optimized, bios modded and undervolted. less than 120W is unreal. if you see numbers like 90W or 100W that's only core power. the rest is not being counted, which is obviously not real.

For RX 580 you have to use settings -cvddc 830 -mvddc 830 with lower GPU frequency to achieve stability (may be 1150 Mhz, it depends on ASIC quality of your GPU). Most of energy consumes your R9 cards.

Various RX 580s 8gb sapphire nitro has best cooling according to me. All other brands fan is failing after 3 years of runtime :-)
Each card separately fine tuned (could do more) :-)
Avg setting 1180 core @840mv , mem 2100@850mv using claymore with straps 1,2 rxboost 1 -y ....
I get average 32.x mhs @ 135watts on each gpu(miner shows 85watts average), could make it more efficient but dont want to reduce hadhrate as have fixed power rate :-)

6 gpu rig total : 196mhs@850watts off wall. . Claymore shows 540 watts gpu consumption lol, i wish :-)

You know, I tried most of the mods that someone in this forum and also in the other forum to my sapphire nitro 570 8gb (micron) but i only got 28-29.5MH until some of my cards got bricked and I tried to bring back to it's original mods but error code 43 shows up in some of my cards.

Dear

I have Sapphire Pulse RX 580 8GB with Samsung Memory chip.

My claymore says it is using 100 W per card, and settings are 2100 memory and core 1150
I used Polaris flash for bios.

Can you help me please to have lower power consumption?

This is what I use in claymore

-epsw x -mode 1 -dcri 5 -asm 1 -mport 3339 -mpsw API2018 -cclock 1150 -cvddc 940 -mclock 2100 -tstop 80 -tt 60 -fanmin 60 -fanmax 100

Thank you

You can try -powlim -20 or test if you can lower -clock 2100 to get same hashrate
