The worst part is I can post, enter windows, run memtest86 etc. It's just I get CPU bus/interconnect errors fairly quickly and occasionally a memtest86 error.
Same here. I updated my 5600x rigs uEFI this AM to give it another whirl.
The normal 3600/1800 boots right up and allowed me to input my previous stable CL14 clocks without any stability issues.
I can't boot 1900 FCLK. Tried multiple times, but eventually gave up.
I can boot 2000 FCLK those WHEA warning errors instantly pop up
After scratching my head I tried 1933 FCLK just to see and it booted right up. I haven't tried tweaking it yet, but no instant WHEA errors or any WHEA errors yet. 3866MHz with some really loose timings CL18 which isn't going to fly with me. I'm going to go back in a tweak the settings slowly to see how she goes.
Memory tweaking requirement for me at least
Spare power switch connected to the cmos jumper as mine lies beneath my 6800
Batch file to clear the event viewer....I know it's best to not clear them, but I tweak my rig then just reload windows once it's stable and to my liking.
