Hello all,

I have got a rig of six Sapphire Nitro+ RX570 8GB. I have modified and flashed them with one and single bios. Now every single GPU is hashing at the rate of 28.8+ and power consumption bellow 110 watts and temperature not reaching 60^c. Process clock: 1125, memory clock: 2000. Two gpu's not giving a single memory error and the other four is throwing errors but still keeping hash rates stable.

How is this possible that one and the same bios is working differently on 6 and the same type of GPU's. How to resolve memory errors? Should i try to overclock problematic cards at the lower levels?

Any suggestions?

I'm trying to reach your results on same cards - and having hard time getting beyond 25 mh/s (Anorak mod OR Polaris OneClickPatch BIOS Mod)
Which BIOS mod did you use?
I want to try and see if I get same errors with same speed

Well, I have tried these mods as well, but no luck there so after researching I have decided to go ahead and mod it myself. Here are few links that might help you.
