EVGA Support is just adding more fun to the mix...
I asked them for advice yesterday after my black screens (card still alive), sent over logs, GPU-Z screenshots and everything.
They told me to use the latest "stable" bios instead and sent me an old bios version (94.02.26.48.16).
Precision X1 immediately told me that now Resizable Bar was disabled and I should update the Bios..... gg
