Hi.

I recently obtained a pair of RX 580 8GB Sapphire Nitro+ SE and tried it for mining. I was very disappointed to see that it only reaches about 18 Mh/s out of the box (ETH) . I tried many different things and by modding the VBIOS to according to the guide for LE (limited edition) I managed to get it to 24 MH/s. It´s still very disappointing when most people get 25 MH/s out of the box and around 30 MH/s with modding.
I cannot find any guides or info at all about this specific card when it comes to mining (or anything else for that matter).
So can anyone please help me with this? What can I do to increase my hashrate??

Thank you!

HI! I had the same problem ... When i plug in my card i only get around 19 mh/s :( so i was searhing on google how to increase hash rate with no luck ... and then i watched video on youtube how to flash bios etc. and i saw that u have bios switch ... and i said to myself let me try that :D and i did and i switched to "silent mode" or something like that and i now i get 22.1 mh/s :D i ll try to flash my card soon and i hope i ll boost hashrate lil more :D i hope that helped! Good luck ... :P and btw can u point me to some tutorial how did u flash ur bios? tnx!

Switch bios to silent mode and than flash your card. 

please upload stock bios (silent and turbo)

rumours say that the special edition has overclocked memory and I think they relaxed the timings due to high ecc error rate incoming

I have two Sapphire RX580 Nitro+ Special Edition (Blue Shroud/LEDs)

ROM Located at link below:
https://drive.google.com/open?id=0B3Sz3h7CSB_4TG1lWXF3dGtDdkU (https://drive.google.com/open?id=0B3Sz3h7CSB_4TG1lWXF3dGtDdkU)


Here's what I did:

Copy the following strap to 2:1750, 2:2000, 2:2250 only.
777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB0300000 01B162C31C0313F17

Change third line of "Memory" section to "2000." The purpose is that we're applying more aggressive timings, so I'm downclocking the memory to compensate (just in case). This way I have less of a chance of uploading unstable settings and giving myself a good headache trying to fix it. You can overclock later in Afterburner.

This got me to 28Mh/s stock.

In afterburner I then tested each card slowly and systematically. Each card is different and can handle different settings. Surprisingly, I found the below settings worked for both of my cards (81.1% and 76.7% ASICs)

-96mv
-21% Power Limit
- 1154Mhz Core
- 2250Mhz Memory

Yields 29.2 MH/s Eth + 497Mh/s SIA in dual-mining mode.
Yields 30.6 MH/s Eth only (test DAG 130)
Power Usage = 132W (81.1% ASIC)
Power Usage = 137W (76.7% ASIC)

Of the 12 cards I own, these are the only two cards that can hit 2250Mhz on the memory and run stable while dual mining. After 90 minutes, I have 3 errors on 1 card, and 6 errors on the other according to HWInfo64, which is very acceptable.

Obviously much better power usage to performance on the Nitro+ RX570 cards, but these are the best RX580s I've worked with hands down.

Would you say the Blue Special Editions perform better than the regular Sapphire RX 580 8GB cards for mining? Thanks!

With modded bios and the same strap i have quite stable rig with no errors(zero error) and no crashes.
Rest of My settings are like those differently :
Power limit -5%

-36mv(minus value)
-5% Power Limit(minus value)
1150Mhz Core
2250Mhz Memory

Epoch no 143
Result 27MH/s

Note: hashrate drop is because of AMD driver . It s been upcoming fixed driver soon hopefully

you have to make sure if your Memory is Samsung or Hynix.. My Sapphire RX 580 SE came with SAMSUNG memory and is hashing like a boss after mods.

I check it hynix, when i try to mod it seemed half hynix and half samsung

Hi there,

Thanks for your suggestions and this mod rom. I also have two of Nitro+ RX80 SE with Hynix memory type. I just wanted to be sure that your modded rom and strap values are going to work on my GPUs as well. Or should I first make a copy of my card's bios and edited it to your suggested values?

You live under a rock? They already released the blockchain drivers.

Yeah, here is the link for de AMD Driver to blockchain:

Hi,
when you said: Change third line of "Memory" section to "2000."

Can i change third line of Voltages Tab ?

I have: Mem controller VDDCI
- 300      1000
- 1000    1000
- 2000    1000 (This value to 2000)   ???

Thanks

Yes, I have 2 different memory types showing also (samsung & hynix) and cannot get any of my sapphire rx 580's 8gb Nitro + cards above 21mh ETH + 62mhz LBR (stock out of the box bios is 19eth and 57lbr) - I have tried many bios, manual mod, copy straps, everything - No need to try overclocking If I cannot even get the stock bios to hash higher ... dual memory is different with our cards reason for us having problems. I see a few other posts about this dual memory problem but no solutions yet.
 Also have 1 rx 480 8gb sapphire running on same rig  - mod strapped bios/samsung memory - the 480 is getting 23mhz ETH + 67 LBR ... outperforming each 580 --- talk about frustrating! lol

 

I have the same issue
RX580 8go SE with half Hynix half Samsung and 512kb rom

I can't reach > 25 mhs eth only :(

please help

With Windows 10 v1709 (Fall Creators Update), make sure you running the latest Crimson Relive 17.1x.x drivers with the 'compute' toggle on for each of the cards in AMD settings or the AMD blockchain drivers in Windows v1703. I have the same cards with the same dual Bios and get 31+ MH/s dual mining with DCR 875 MH/s with a core clock 1200 MHz memory clock 2100 MHz. I use the Polaris Bios Editor v1.6.2 'one click timing patch'. It automatically detects each memory type and adjusts the 1750 MHz and up straps with the bundled performance straps. PBE v1.6.3 and up adjusts the straps from 1500 MHz and up, but the 1750 MHz straps are more stable.

Thansk VAN
could you please update the rom link (I need the 512kb version)

and maaany thanks

Please upload yours oryginal rom to: http://www.zippyshare.com/  i will change it for you.

here you go : original rom
http://www78.zippyshare.com/v/frGdyx4y/file.html

http://www87.zippyshare.com/v/m5D6CY2v/file.html This rom contains only changed timings. Please test it and if you want we can adjust it be more "green" :_)

On windows 7 it's only 20 mhs eth :(
I will switch to windows 10 an update you

Sure, please use latest version v1709.

I'm running on Win 10 v1709 and Crimson Relive 17.30.x. There is no GPU workload with "compute" toggle. My RX580 8GB are getting 25 MH/s on stock, should I downgrade Relive to 17.10 and I'll be able to see "GPU Workload" toggle there?

Edited:
I think it's fine to run on 17.30.x, because there is a note for the driver: This driver is not intended for graphics or gaming workloads.

Download the latest driver from the AMD website if you're on Windows 10 v1709 and do a clean install after running DDU in safe mode to remove the old drivers. Be sure to enable the option in DDU to disable the Windows automatic driver installation.

finaly I get my >31 mhs with this rom

Hi. Im planning to buy this GPU, wich one its better? Special edition or the normal nitro+? the se its 10 bucks more expensive...

I have both the Sapphire Nitro+ and Nitro+ SE RX 580 (blue shroud cards). I have the best results with the Nitro+ non SE RX 580 cards. Both the SE and non SE cards overclock well after a simple Polaris Bios Editor v1.62 'one click timing patch' Bios mod and run cool. The non SE cards are cheaper and I prefer them. The blue RX 580 SE cards also have annoying blue led fans that can't be turned off.

shit that blue led for the fans makes it look spiffy as hell lol, though even I have to admit its lit up way more than I thought they were going to be lol. its a awesome lightshow with the lights off though

If I'm not mistaken, you might be able to at least change the colour of the blue fan lights with sapphire trixx - possibly even turn em off?  One thing for sure is that after mining with them for a couple of months, the original cool blue lights will turn greenish due to the heat that the gpu's put out.   I just picked up a batch of the SE blue cards this week and you can really tell the difference between my 3 month old batch and these new ones.

I just picked up 5 x Sapphire Nitro+ SE (Micron Memory)

All 5 of them hash at 29.6-30.5mhs in silent mode without touching the bios. Running Aug 23 blockchain driver.

My oc settings are:
Core: 1150
Memory: 2250
Core Undervolt: -96
Memory Undervolt: -96
Fans: 50-80%

All above is applied via command line to Claymore 10.2

This gives a power at the wall of 125w per card and 83w in GPUz

The cards have been running for 12hrs with no errors at all and temps between 50-60C

The only odd thing i find is that in Polaris it only has 1 set of straps 0: which is why i havnt bios modded them.

ETH: 0x66ff2c45e37f0d574016c28651866ac07ddf27a5

You need a better Bios editor to correctly show straps on all rx580's - Here is a good one:

https://bitcointalk.org/index.php?topic=1882656.0

nope the color on the sapphire nitro+ rx 580 8gb SE is BLUE only, pretty sure if we could do other colors, there would be a button like on the regular rx 580's and 480's

Hi Vann - Can you advise where i can find the "COMPUTE" (probably a screenshot). I have windows 10 64 bit professional edition with Crimson Relive 17.1X drivers from Aug 23 stock bios. Haven't used Polaris BIOS Editor though. Am trying to find COMUPUTE toggle in AMD Settings.

P.S: I have RX 580 Nitro+ Special Edition with Micron Memory (Blue one with Blue LED). Right now am getting 25 MH/s dual mining ETH and SIA without any modifications and Modding. Any advise on how to get it up to 30+ will be very helpful.

The latest AMD Adreniline drivers are the ones you want to use with Windows v1709. The compute toggle is is under AMD settings. You need to set it under each card and reboot for it to take effect.

https://youtu.be/xKlXDHdCtqM?t=12684

The lastest Polaris Bios Editor v1.6.6 'one click timing patch' worked very well for the latest Sapphire RX 580 Nitro+ RX 580 8GB card that came with Micron memory. It's been running very stable.

My friend have the card and he is getting 30.3 with it dual mining without any problem , My own 570 nitro + get the same results . Maybe try use DDU and reinstall AMD mining drivers and use windows fix after your flash your cards . And on the other point , Getting different results from the same card that have same memory is a normal thing . Out of 19 rx 570 we have ( all elpida memory ) only one of them can not get more than 1950 OC for memory the rest is stable at 2050 without any problem so I have all of them 30+ and only one 28.5+  , So getting different results even you have identical cards is normal .

Thanks Vann. I tried on time click patch and a few other mods posted on this forum and elsewhere and no matter what I can't get more than 24.5 Mh/s. Am dual mining ETH + SIA using Claymore 10.2
Do you think that might be an issue? What are the flags I need to set in Claymore?

I have uploaded my Stock ROM here. Anychance you can take a look. No worries if you can't. Thanks,

https://wetransfer.com/downloads/4f65d9530d3c1ae290ff8d97d94543cb20171229164538/0dd286d9750161d6d149a02e0fa8e48f20171229164538/d2f06e

The Bios on your card appears identical to the Bios on the Nitro+ RX 580 8GB non-SE card with Micron memory I have. Both have the same checksum. I use the PBE 'one click timing patch' and it works for all of my cards. If it's not working check:

1/. You are using the AMD Aug. 23 blockchain drivers or the latest Adrenaline drivers with compute mode enabled.
2/. You have set virtual memory in Windows to at least 16GB for a six card rig.
3/. Check your clock speeds with HwInfo or GPU-Z. For the card to take advantage of the Bios timings, you need to overclock the card. For an RX 580 I use 1200 MHz core clock with a 2075-2250 MHz memory overclock, depending on the card.
4/. When dual mining, check the -dcri setting in the Claymore. You can adjust the value up or down manually with the "+/-" keys. Adjust it until the hash rate on the secondary coin increases without affecting the hash rate on ETH very much.

You were spot on mate. After sending you the message, i came across this article http://www.reddup.co/r/EtherMining/comments/7enbka/tutorial_how_to_successfully_mod_your_bios_amd?st=jayjycrk&sh=7a7ce2f8

The last line of the article said to reduce the -dcri to 1. When i did that, my hashrate went upto 32 mh/s for ETH but 10 Mh/s for SIA. I started playing around and at around -dcri of 20, though the SIA hashrate remains constant, ETH starts going down.

Right now at -dcri of 20, am getting ~30.5 for ETH and 600 for SIA which is optimal. I will keep play around a little bit and keep you and the forum posted.
Thanks again for your quick response and help.

If thats true, proper bios would probably give 33-34MH/s

This is true! My RX580 8GB Sapphire Nitro+ SE (Micron Memory) has 29.130 mhs without flashing bios

Hi, for those having issues with 27 Mh/s max on 580 Nitro+ 8GB SE (Samsung) maybe this will help. At least it did help me. The problem is the dual-memory types in such GPUs.

anyone have 6x of these running on an h81 pro btc r2.0 mobo, I'm having some issues wondering someone could lend a hand, ive pretty much tried all that I can!


problem explained here
https://bitcointalk.org/index.php?topic=2848780.new#new (https://bitcointalk.org/index.php?topic=2848780.new#new)

Getting my Rx 580 next month after a 1.5 month delay in delivery... Will see how it performs!

Drop Voltages and Clocks to save some juice :-)

875 1150
875 2050-2250 (depends on the Chips ya have ... and the mod ya have done ...)

Should get the 580 down to +- 85W GPU-Z

my rom 260 sol/s in zcash, 28 mhz in ETH/ETC. If you need, pm email for me, i sent you my rom.

No, i meant that you 1st adjust and tweak the voltages the gpus need. A Bios change is the last step of a few - and not really needed.

It depends on: your miner (if there are options to adjust voltages/clocks), your OS (W10/Linux)

As Example on W10 you can use AMD Wattman (Part of the driver) to set profiles for every GPU and adjust there the clocks and voltages and you are set and no need to mod the Bios ...

Do you have the right drivers installed? I had a driver with a bug installed and could not get the card more than 26Mh/s.

Reove your driver with DDU and install the last AMD Blockchain driver. that did the trick with me. Have them now running at 32 Mh/s. 

This card can mine > 30.5Mh/s depending on memory.
I have mod more than 20 and they are mining on HiveOS around 31.5.

Most of them have dual memory Samsung/Hynix. Samsung Timing from Ubermix is not really stable.

This Timing is stable for Samsung K4G80325FB on those GPU.

Did you ever make a ROM for your cards, and are they P/N 113-1E366CU-S5S ?
All the roms I find are for P/N 113-BE366EU-Z48
