Since driver version 24.3.1 it is possible to overclock more vram on RX7900GRU card . If I do this the game with this oc vramu runs a few hours without any problem but if I exit to windows randomly the computer crashes , it makes a gray screen and I have to hold down the power button to restart it.
Do you also have this ?
