Hi, I have a not overclocked 1800X with 64 GB Ram. No XMP Profile too.

I get some instant reboots with MCE Log error Messages during Boot.:

Trying to decode it with mce log leads to:


Hardware event. This is not a software error.

Watercooled. Reboots often during idle.


So I've switched Mainboard already (Newest BIOS Versions on both), what should I switch next? Memtest 68 claims memory to be ok.


These are Linux Error messages but I had reboots with windows too.
