I just upgraded cpu, mb, ram and I have an issue with No Video Signal in BIOS via Display Port 1.2 cable with XMP profile enabled. When XMP profile is disabled I can see booting proccess and I can see bios too. If I enable XMP profile I lose signal after restart and I cannot see anything until Windows 11 is loaded. I cannot get into BIOS too, well maybe I am there but screen is black. My GPU Status LED on motherboard is ON all the time when XMP is enabled even though my GPU is working without problem in Windows. I have tried all BIOS versions, different GPU, still same issue. My memory kit is officialy supported on that motherboard. Only way how to see BIOS with XMP enabled is using HDMI cable, but then I am limited to 50Hz on my monitor.
Any idea what else could I try to fix that? I just don't understand how enabling XMP profile can cause issue like that.

Haven't heard of that before, I know XMP can change things other than just memory (e.g. other voltages), but not sure why it would do that. What happens when you set the memory frequency and voltage manually?
 
I have tried to set the memory frequency and voltage manually and same issue again. Different memory kit with EXPO profile enabled causes same issue. For whatever reason I thought my monitor support only 50Hz via HDMI cable, but it can do 100Hz. So I guess I am gonna use HDMI cable from now on.
