Hello doktor,
My hashrate still drops with vega 64, even with 100% fan config in afterburner (8500 to 6000h/s for 6 gpu) after few minutes.
Do you think it is better to use overdrive for this or it will change nothing?

Is it a driver problem? I have Amd Crimson  016.001.001.000 , should i change?

Last question: i can set my mem clock to 1100 max, after this, it reboot my computer, is there a way to go higher, or will it change nothing?

Thanks a lot for your help!
