I've 2 Vega 64 cards (Specs says : Sapphire Nitro+ Vega 64 @1580mhz + Asus Strix Vega 64 OC @1590mhz).
When enabling crossfire/mgpu on games that works with, both cards are overclocked to 1670mhz..! Is this a normal behaviour ?
All games I've tested have stuttering, worst performance, hang, freeze, or crash...
Even when I limit power to -10%, cards still overclock a little mhz..
What i'm doing wrong ?
