I've been experiencing stability issues with my system from the start (month ago), but thought it only happened when I enabled DOCP.
However, today I discovered my system crashes (black screen, no reboot) when running Unigine Heaven for about 5-10 minutes.
Everything is running at stock speeds (No CPU/GPU/RAM overclock).
I've tried undervolting and underclocking the GPU, while running fans at max speed. No effect.
Disabled PCI 4.0. No effect
Tried drivers 20.7.2 and 20.4.2. No difference
CMOS reset of Motherboard. No difference
Chipset and BIOS drivers are the latest version.
Temperatures are fine (50-60 CPU, 70-75 GPU)
Full specs:
Sapphire RX 5700XT Pulse
AMD Ryzen 5 3600
Asus Prime B550M-A (wifi)
Corsair TX550M V2
Crucial Ballistix BL2K8G32C16U4B
Any suggestions as to what might be causing this?
