Hello I need help Rx570 580

[winters]

Hello guys can anyone teach me how to OC my Rx570 and 580 2 cards, I’ve flashed the Vbios and try to set OC but still got 22~25 Mh/s

HI,
Core at 1150 vdd 850 mem at 2000 remove DPM values… Fan at 80-90%
Also under OC settings use Aggressive Under voltage… And REF values (Micron 30 ,hynix 30)

[winters]

Thanks a lot bro.
better now.

are you sure you did the bios mod ? Hynix can go with 2150 mem clock . test it. Core clock is as the other dude suggested 1150.

[winters]

thanks dude, but 570 with 2150 mem clock the hash rate down to 21, so I put it back to 2000.

[rkulov]

why did you reduce the core clock to 1100 on the rx 580 ? put it back and if it crashes icrease a bit the core voltage to 860-865. Also the same for the rx 570. 1150 core clock.
try 2100 mem clock.

My RX 570 is with samsung memory and it uses settings :
1185 Core clock
862 core voltage
800 Memory controller voltage
2150 Memory clock

rx 580 is ok now

rx 570 down to 20~21

I think I just flash the original BIOS from hive os, should I go to techpowerup.com download the new BIOS?

[Mjuarez]

use this.

[winters]

Thanks dude, but nothing changed with the value you provide.
But still thank you

Download the stock and mod it with polaris. Then upload it in hive and restart rig

Hi @winters
I think - if you are mining ETH - you can get better Mh/s, at least 31 and more with your RX 570 & 580 .
I agree with @rkulov , do you sure you did the BIOS mod?

[winters]

Hello
I was download the BIOS and flash,

and the hash rate is better now.
Thanks a lot you guys.
