Topic: hashrate problem with 2 RX580 (Read 169 times)
even my worst card will do 30,6mh/s. most of them doing 32+. But it's ok.
yeaaaaaah that's ok now !!!
I removed the blockchain driver, and installed the latest driver AMD, and switch in compute mode !
what do you think about these performances ?

Seems fine
you may also look if there's a significant hardware errors thru the hwinfo

then you may adjust its clocks to minimize it
this is for mining reliability

Youve probably flashed the bios with wrong memory speeds for the brand of memory installed - even if you bought all the cards at the same time, they can have different memory manufacturers. Did you check what memory each card had and flash them with the right bios - one at a time?
edit - actually - just re-read - weird that they go full on when one at a time? Cant think what thats about. But I'd def flash bios back to original and see if its still happening.

you can download the lastest drivers and than in settings you enable Compute mode and i going to work as it should.
If you are using win 10 , then yes ....
Under windows 7 you might going to have some problems to switch to compute mode from radeon settings

Hi guys ! In first, sorry about my english :-) (my own speaking is french)
I have two RX580 8gb nitro+ special edition, I have modified the bios, the driver installed is the crimson blockchain, I have disabled the crossfire mode in the radeon's software, I have overclocked too with MSI afterburner .. If I only use one card, the hashrate is 28 mh/s with claymore.
But,
If I use the two card in the same time in my computer, the hashrate is .. around 16 mh/s ..
I tried with claymore v 10.5 , 11.5 , 11.7 , 11.9 and it doesn't change anything...
Maybe you can know what is the problem ??
Thank you very much for your help !

are u using windows 7 or windows 10 ? why are you still using the outdated blockchain driver ?
use the recent radeon driver / windows 10 / switch your cards to compute mod with radeon settings , or with the tools tg88 mentioned earlier.
Try applying this tool and see if it solves:

I don't know how you have modified the bios, but I suggest you do a re installation of Windows, better to find a Stripped down to mining ISO version of Windows 10 Pro, or go with the best Windows 10 , the Enterprise version if you can find one. Install Windows then 1 card, use Polaris 1 click bios editor together with Atiflash 2.77 and ati patcher. After you make the bios modified test it after the restart if it is at 28-29 mhsh with memory clock overclocked at MSI, it means it is ok. Repeat the steps now with the second card. Always use Blockchain driver as long as you don't have more than 8 cards.
It should work without problems now.

does it have anything to do with dag size? I also have a problem with my rx580. if dag size<200, hashrate is 28-29mhz. but when dag size>200, hash rate is 15-16mhz. I used claymore miner and windows 10. are other people experiencing the same problem?
