Has anyone been having unreliability issues? Both my rigs just stop mining after a few hours. In the log all the GPU just go to hashing speed 0
Yes, and while I can't say I've claimed victory just yet, so far it appears that dialing back a little on the memory clock is helping. Prior to that Windows 10 would BSOD with a TDR video failure, sometimes before starting the miner, and even after I DDU'ed 18.6.1 and reinstalled it (pixel patched, etc.).
So far I have been mining for a couple hours at 1860 on the mem clock (1200 on the core clock) at full power and not really seeing a reduction in hashrate from when I was running at 1200/1900.
Thank you. I will try that!
