I built my first Cryptonight rig a few months back using Sapphire Pulse RX 570 and was able to get 915 h/s @ 95 watt on the wall. Due to high prices and unavailability of RX 570s, I decided to give RX 560s a shot. I am glad to mention that I am able to obtain 515 h/s @ 40 watt on the wall for AMD RX 560 while mining Electroneum/Sumokoin (will be true for all Cryptonight coins e.g., Monero, Karbo). You can see the proof of hashrate and clock settings at this link: https://imgur.com/a/q1iKk

I am using sgminer-gm 5.5 with rawintensity 416 and worksize 8. The trick was to use 2 gpu threads in the config file as follows:

"rawintensity": "416", "worksize": "8", "gpu-threads": "2"

My GPU is Asus OC 2gb Polaris 14nm 1210 Ghz core and 1750 Mhz memory clock. It uses Elpida DDR5 memory. Its bios is modified using Polaris 1.6.6 editor's one click patch option and that was pretty much it. (I tried Sapphire RX Pulse 4gb version but could not get it above 410 h/s).

I tried Crimson Beta 17.30 Blockchain driver but it kept on crashing. Finally managed to make Crimson relive 17.7 work.

You can try gpu platform 0 or 1. Generally one of these two is the Intel's integrated gpu and the other one is your openCL platform. Save this as .conf file and then run a .bat file which has the following contents

@echo off

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

:loop
sgminer -c name_of_your_conf_file.conf --gpu-reorder
echo restart miner...
goto loop

Currently getting 420h/s on Hynix. Using Awesome miner, will this increase my hash rate?

can u upload your modified bios please

I'm not at home, but all i did was use the one time click patch and overclock memory to 2100+.

You can try using sgminer with two threads. With single thread on sgminer my speed was around 440 h/s. With two threads i was able to get 515 h/s.

Sounds good, I haven't used SG miner. Any tutorials you recommend to get it set up? Getting 420h/s on Hynix and 460h/s Micron without your modified miner.

Thanks

Which cgminer do you talk about ?

This one ?
https://github.com/genesismining/sgminer-gm/releases

Or This one ?
https://github.com/nicehash/sgminer-gm/releases

Or another one ?

I do not have access to any tutorial at this point. But you can setup it very easily. All you have to do is setup a .bat file and config file. Above I have given examples  of my .bat and config file. Simply copy and paste (change wallet and pool address accordingly).

It is the first one from genesis mining https://github.com/genesismining/sgminer-gm/releases

good, my Sapphire RX550 2G Pulse got only @470H/s, 1.4K for 3.

Thats pretty good for such cheap card, according to whattomine site, Nvidia GTX 1080 has result
580, and you can buy 5-6 rx550 cards for the price of one GTX 1080

This is good hash rate for RX 550. What are your mem and core clock settings?

I can't get the same numbers, saphire pulse 2gb lite, elpida ram, one click patch. 440-460 h/s

Try mining dero with cryptonight algo.
If you need coin with purpose and more than just fork or gui wallet go for Dero,
research you coin first and read carefully the details about it.

Hey !

I've 6x Gigabyte RX560 4gb Micron Rev2 and i'm looking for the same hrate.
Can you share a bios and the oc please ?

I've god 370h/s with SMOS and 1050/2000 OC

I would be grateful

Thank you for sharing this website: https://www.cryptunit.com/. Really helpful.

Hey Mate, I used Polaris 1.6.6 one click patch to modify the default bios. That was it. Not sure how to share a file on bitcointalk.
My oc settings are 1130 for gpu and 1950 for memory.  Btw, I am using Windows 10 and sgminer. So not sure about SMOS.

I ran into the same issue with Sapphire pulse 560 4gb. Could not get over 410 h/s. So I switched to Asus 2gb card which gives 515 h/s

So, i had to downclock my cards to 2000 on memory as it was unstable. Looks like your settings don't really help, only about a 10h/s increase on each card 😐 I have gigabyte 4gb rx 560s. Any ideas?

Which miner you are using and what is your config file? Also, do you know how many compute units your card has? You can obtain compute unit values by running Claymore cryptonight miner. It shows compute unit number at the start.

Wow - very eerie to see the exact same numbers that I came up with for my 2GB XFX RX 560's so I gave you your first merit!

How did you arrive at the rawIntensity number? I found a few bits of advice from one of the SGMiner-GM devs - OhGodAGirl - in several threads:


So I started with rI of 256, worksize = 4 and gpu-threads = 2 and got fairly anemic results. Changing worksize to 8 improved hashrate, while changing gpu-threads to 1 reduced hashrate, so I went back to 2. Right then I knew the above info wasn't useful, so I decided to do a binary search to find the best rI. Since I was at 256 the next increment was 512, but that resulted in SGMiner-GM crashing soon after starting up. Next up was 384 - halfway between 256 and 512 - and that was faster than 256, so next was 416, and that was faster still, but by a much smaller margin so I felt like I was getting pretty close to the optimal setting. Turns out that was just a tad too high because the rig would still crash after a few hours so I dropped rI to 408 and it's been humming along ever since. My average hashrate isn't quite as good as yours, though - 458 H/s per card - but it's a lot better than the 330 H/s or so they delivered in stock form.

I like your systematic approach to reach these numbers. I followed slightly different calculations for building my rx 570 right. I ended up using rawintensity 896 and worksize 8 for my rx 570s. Since rx 560 uses 16 compute units (as compared to rx 570 32 units) I halved rawintensity and then reduced it until I reached optimal value which is 416. I ran my 560 for 3 straight days without error. Btw I like to restart my rig after every 24 hours automatically.

Using XMR stack. Have 16 Compute unit cores and the memory is 7000mhz, Flashed with click auto bios. I have been altering my config files like changing intensity, worksize, etc. Feel like my cards are just a bad bunch :(

I was having troubles getting sg miner to work. Will get it sorted tomorrow when I have time.

https://preview.ibb.co/dqkLY7/sgminer_error.png

I'm getting these errors using sgminer-gm v5.5.5

Any ideas?

Try sgminer version 5.5 from genesis mining. I am currently using this version and it works great with core 1130, memory 1950 and 950 mV undervolt. Take special care of gpu-platform settings. 

Please share your config file. Looks like a driver or gpu-platform setting issue.  Also, which driver you are using?

Right now, sgminer is initializing the  built-in intel HD graphics card. You need to tell sgminer to use AMD cards. Try setting --gpu-platform 0  in your .bat file. If that does not work, try --gpu-platform 1.

Micron isnt really great, my elpida and hynix cards all do close to 500 hash.
Micron i cant get over 440 hash, this is my micron memory strap for 1500+ mhz:
777000000000000022AA1C00315A5436A0550F15B68C1506004082007C041420CA8980A9020004C 01712262B612B3715

RX560 not good to use cryptonight, because RX550 more cheaper and easyly get 450h/s.
User 560 for eth forks mining

My 560 Micron is doing 499H/s, My Hynix 560 is doing 474h/s pretty stable on HiveOS...

Any body here manged to unlock full 1024 shader on new 560 models, also any idea if there is performance gain from unlocking shaders for ETH And XMR

Not all rx550's are good, i have one sapphire rx550 4 gb micron and its my worst card, 430 hash.
gigabyte rx550 2gb elpida gives 480 hash.


Hi,

I unlocked shader on rx 460 models, and it doesnt give you more hash on cryptonight, makes sence, since the rx550 does same hash in cryptonight with only 512 shaders.
Also my gigabyte rx460 4gb micron got really unstable when i unlocked shaders from 896 to 1024, the msi rx460 2 gb hynix was stable, but not more hash then with locked shaders.

RX 550 isn't cheaper in the US. Check out this sorted/filtered list on newegg: https://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007709%20601296396%20601296397%208000&IsNodeId=1&bop=And&order=PRICE&page=1 (https://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007709%20601296396%20601296397%208000&IsNodeId=1&bop=And&order=PRICE&page=1)

If you can get an RX 560 for the same price, or even less, than an RX 550 why wouldn't you? Unless, of course, you could get an RX 570 for MSRP... but that hasn't been possible for a couple of months now.

Ya if they rx560 cost the same as the rx550 i think i also would buy the rx560.
But the rx550 does hash at same speed as rx560 with lower power consumption ( about 35 vs 22 watts in GPU-Z) This is for cryptonight algo only.
But the rx560 is faster in ethash and equihash, so it really depends on what you want,  where i live power costs 24 cents/kw/h, so for me the rx550 is better buy.
If you only pay 5-10 cents for power i would buy the rx560.

I tried 1 rx460 2gb sapphire, with samsung memory.
The auto tune in polaris bios editor applied Ubermix straps.
Managed to reach 500+ h/s at cryptonight with windows 10.
But when I try with SMos, I only get 420h/s.

Any idea why ? or any suggest to reach 500 again in SMos ?

Are you using the same version of mining software and AMD driver in SMOS?

Hi, I have Sapphire pulse RX 560 2gb

I'm wondering if you are still mining with that card and which miner, SGMiner has not released update version to support the new cryptonight forks

Thanks!

I still mine Ethash and CryptoNight forks with my 2GB RX 560s - right now they are on MUSIC (Ethash) - but for CN-forks I use xmr-stak (thread: https://bitcointalk.org/index.php?topic=3264773.0 (https://bitcointalk.org/index.php?topic=3264773.0)). Other people have reported good results with SRBMiner (thread: https://bitcointalk.org/index.php?topic=3167363.0 (https://bitcointalk.org/index.php?topic=3167363.0)) but I haven't tried it myself, mainly because it took quite a lot of tweaking to dial in xmr-stak so I am loathe to abandon all that time and effort...  :P

Didn't know that MUSIC it's multi-algo, but I prefer CN algo because low: heat and wattage

I'm using xmr-stak but I it does not have the gpu-thread option like SGMiner, the OP said that increasing that option to 2 gave a little more h/s, appart from the bios mod

I have not played with the xmr stak options, I just let it by default and in fact the cards are 1000/1750 since I'm working so not much time in home to check, only with teamviewer

BTW what it's your hash in ethash, cn-v7 and cn-heavy?

No, I meant that I use my 2GB (16CU) RX 560s for both Ethash and CN, but for Ethash I am restricted to MUSIC or UBQ because the DAG files still fit into 2GB. Right now they are mining MUSIC and doing 14.3MH/s per card, which is a little over half what a 4GB RX 570 will do, but at much less than half the price (at least that was the case when I bought them back in Dec/Jan).

As for the CN forks, I use xmr-stak 2.4.2 because it performs the best so far and is very stable. It does not perform well "out of the box," so to speak - the config files it generates (amd.txt and cpu.txt) need to be heavily modified. My amd.txt file modified for just 2 cards is shown below. If you have more than 2 cards then increment the index parameter for each additional card but copy everything else (assuming they are identical cards) and put those lines before the ], at the bottom.


I get about 495H/s per card with this congfiguration in CN-v7; I have not tried the other forks because I am not interested in any of the coins that use them.

Cool!

Allright I see where is the gpu_threads in xmr-stak, so each line represent a gpu thread, a gpu can have more than one thread

I will test it with CN-V7, CN-heavy works differently, I tested using two threads per gpu and it crashed so I need to do some tests here

What are your clocks? do you have moded bios?

Thanks

Generally speaking, it is better to drop the intensity value for each thread for heavy rather than go back to 1 thread per GPU (as you've already tried). I use a binary search method to find optimal values in the shortest time. For example, if intensity ranges from 0 - 1024 I will try 512 first and if the card hashes I try 768 next; if it crashes I try 384 next; etc and so on.

I am running a modified BIOS on the cards - a "Powersave ROM" from Anorak specific to my card brand/model - and custom voltage profiles. Max core clock is 1200MHz at 1025mV and max mem clock is 1900MHz at 1000mV. These values almost certainly won't help you, but I will say that OverDrivenTool is far better at this sort of thing with AMD cards than MSI AfterBurner, and pretty much the only option if you have 4 or more cards (MSI AB breaks if more than 3 cards are present).

Yes, Heavy it's a lot different than V7, need to do a lot of test to get the proper config

The other thing is the driver, now I have 17.4.4, I installed 18.4.1 and one of the three cards was giving half h/s, I quickly uninstalled and installed again 17.4.4 and it's running fine

I use MSI AB to set 1000/1750@0.800 cards and does not exceed 60º, I have other rig with 4 rx 560 also with MSI AB and sometimes this rig gives problems, when I have to reboot it, sometimes does not boot, but I really don't know if there is video signal because I only manage it with teamviewer, for now I can't connect a monitor, so I guess this can be MSI AB problem since this rig has 4 cards, well hope so

I downloaded OverDrivenTool but this tools need 17.7 driver or newer, I have not tested blockchain driver and I feel that can be a PITA to get a good driver for my setup  :'(

I'm running the latest AMD drivers - 18.something - with no issue. One peculiar thing I've noticed is that I always have to reboot twice to max out the hashrate of all the cards; if not then 1 or more cards invariably get stuck at a lower hashrate for some reason.

If you do flash a modded BIOS make sure you get the infamous ATI pixel clock patcher program otherwise Windows will cripple the cards that have been flashed (IIRC, still usable in VGA mode to display a screen, but not at all for mining - you can tell a card has suffered this fate if it has error code 43 in the control panel listing).
