Could I please get some Help - Lacklustre Crypto Performance

Hey dudes and dudets,

Hows things?

So I was wondering if I could please get some advice regarding some lacklustre crypto mining performance on my Vega VII.

I had one lying around (long story) and noticed on whattomine.com that it had some stellar mining performance so I decided to give it a crack.

I’m using windows 10 and ethminer (which uses the ethash algorithm) to mine Ethereum. I should be seeing about 80Mh/s ish on windows (switching to linux soon, another long story) but I’m only seeing 45 Mh/s. I don’t have any background processes running that should be utilising the GPU so I can’t explain why such a difference.

Would anyone have any suggestions as to what to investigate to boost the performance?
