rx 6800 low hashrate #308

Open add09 opened 3 years ago

add09 commented 3 years ago

My video card rx 6800. When mining, it shows a hashrate of 25 mh / sec. Am I doing something wrong? Calculation mode is on. Should be at least 50. Please help me. I've already broken my whole head. :)

add09, did you solve this issue? I'm thinking about getting some RX6800s and wanted to see how they work before I do.

I have solved this problem. I don't know why, but the card flatly refused to work at full capacity in Windows 7. I reinstalled the drivers several times (Adrenaline 21.41). Enforced the compute mode using third-party programs. Nothing helped. I installed Windows 10 and it worked. I can't explain why this is happening. I think that for some reason, the compute mode is not enabled in Windows 7. By the way, Adrenaline 21.41 does not have a "compute mode" switch, neither in Windows 7 nor in Windows 10. If you buy and install rx 6800, then another problem may arise. User settings crash when exiting sleep mode or when there is a power outage. If necessary, then I can suggest a solution.

I tuned my RX 6800 (non XT) with MorePowerTool and able to get 63.5 Mh/s at 104 Watts. Followed SonOfATech guide on youtube on this. Undervolting, giving bit more amps and overclocking memory are all there's to it.
