Guys, I'm still dropping to 1500 per card (two vega 64s with 16GB RAM) after 20-24 hours. Am forced to restart everything to get back to 1900 per card. Can anyone share their insights as to what I might be missing? I have the cards running on a rig I remote into, so no displays attached at all (not even to the onboard video). Maybe I need dummy HDMI dongles? Thanks for any help.
I had the same issue with hashrate going to 1700 and had to restart the miner. I noticed that was happening while i was running anything else than the miner that had to do with the gpu ( HWinfo, afterburner). What i did was to lower a bit the oc settings and i was just fine..
Yeah lower memory overclock a bit and you should be rock steady. not all chips are made equal so...lower the overclock on all cards or on just the one that is causing problems.
