After 20.4.2 the memory change to real memory in PhoenixMiner is not half... the crashes come because you push to high the memory... test all of them at 1750 Mhz ...
So I tried driver 20.3.1 and it seemed like it
almost worked.
I was playing around with it for about 10 hours yesterday!
Here are my results:
If they have a hashrate and a wattage it means that it worked for a brief amount of time... that is until it didn't.
Sometimes I get the BSOD that says VIDEO_TDR_FAILURE which according to a quick Google search says that it's likely a bad driver or GPU. But since 19.9.1 seems to work fine I'm thinking it's driver related.
And when I say "crash" I mean that it results in 0 MH/s.

I go back to 19.9.1 via system restore and all work beautifully at 1350MHz Core, 875MHz Mem, 780mv
