I'm experiencing some weird problems with vega64 and the registry mod (
https://www.reddit.com/r/MoneroMining/comments/74hjqn/monero_and_vega_the_definitive_guide/) I used the 1100mhz registry mod for a while now and every 2 days or so, there are large areas of artifacts that appear on the screen but it only appears on 1 window/software. If the window is minimized then maximised, the artifacts disappear.
Did some research and I realised I should have kept my HBM temps low but I kept focusing on the core temps instead. So I set the fan speed to a min of 3000rpm as per the link. even then, sometimes it is hard to keep temps below 82-84degC.
The gpu clock was lowered to 1220mhz instead of the usual 1400+
then things started to get weird over the last 2 days.
1. all the status leds which should have lit up since they were under load but only 1 led lit up despite the card hashing away. then i noticed every now and then, rest of the leds started flashing as if the gpu load was rapidly changing between 0 and 100%
2. a few hours ago, the temps became slightly lower at 72-77degC despite the hashrates remaining at 42-44mhs ( I was watching some videos on the same pc)
3. hashrates started to half, at 22mhs and temps were much lower, about 44degC. Restarting the pc didn't help, reapplying the registry patch didnt work. cleaned out and reinstalled the drivers didn't work either.
but the mem clock speed was set to 945mhz for some reason and it was hashing at 40+mhs? but when I raised the mem speed to 1100mhz, the hashrate dropped to 21mhs?
and now the status leds work fine!
