Re: Vega 64 low hashrate

Set min fan speed to 3000.
It is droping cuz of HBM temp and the fan rpm is related to core temp ONLY.

So, HBM must be bellow 70 witch means core temp must be bellow 60 since HBM is usually 10 hotter than core. You'll need to check that.

If you was getting 2k, its not windows or bios. It is temp.

You dont need to follow the guide but there is a lot of info there. Check windows settings and crossfire in registry.

good luck

HBM are all below 75.

I run my vegas at a temp target of 62 with 3000 prm fan

I think you said it is just the one card.

Can you run it alone again and set the temp target really low and the fan really high?

yea, its just one card. Before it was the Red Devil 64. Since i switched it to other pcie slot, now the vega 56 has a low hashrate.
