So I tested with the DDR3000 the last two days and this evening ended up getting WHEA errors twice in a row for different APICs.Â*
Coincidentally a second 5950 CPU arrived to test with, and I swapped it out, and added back the DDR3600. I set BIOS to default, enabled DOCP (XMP) and booted successfully. As I didnt have a lot of time, I joined some friends for Warzone as a quick bench, played a couple of matches and then when we eventually quit the game my system lost display signal and rebooted. I could only find a critical error for the reboot, and a couple of ACPI warning errors in event viewer for the crash. No WHEA errors. I’ll try upping SOC as suggested tomorrow, but getting a bit frustrated tbh.Â*
