OK so I was able to run a spi32 at 6:02 but then the machine just rebooted and would not post.

After about 2 hours of trying different things I believe my 55x cpu died.

I think I was able to confirm this by putting in the 53x cpu - worked fine, put in the 55x no go, put in the 53 work fine, ...

I was running high v's for benching - cpuv 1.6 to 1.66, agent v - 1.064 to 1.104 with vtt (for memory) at 1.2 and mem voltage at 1.88v under cold water - realtemp was reporting 20's.

Hopefully, microcenter will exchange - too bad - it was a good chip!

Anyone have any other ideas before I return it?
