@CaseySJ with my Sapphire Nitro+ RX5700XT after applying the Radeon patch - and disabling WEG - video signal comes out only from HDMI, not from DP. I think you'd better edit the guide with this info :)
Just made an experiment. I opened the console, disabled the screen saver and waited until the system froze. Going through the console lines, the only weird message is a "AMD Error TODO: to implement support for request power".
Probably it's something related to the power saving feature.
Thanks! Do you have any issues like ours?
Case: NZXT H510i
Cooler: NZXT X62
Ram: 2x8GB HyperX Predator 3200mhz
GPU: Sapphire Nitro+ Radeon RX 5700XT
Wifi/BT: Fenvi T919
PSU: Corsair RM750x
NVMe: 2x512GB Silicon Power
That's my build. Memory with XMP Profile 1 to 3200MHz on F8 BIOS.
I think our Sapphire GPUs could cause the freeze/reboot just because I had the same issue this summer. Replacing the Sapphire with an old Asus GTX770 solved everything. So yes, it could be our GPU or at least something with drivers.
