More issues: While running prime, after 5 minutes, it was shutting the PC off although the temps were in lower 80s (it shut itself off right under my nose, I was watching the temps). So, I disabled the shutdown at 100C in BIOS. It can't even boot the damn thing. It displays 88 code. Reset and same thing.

Any ideas on what's shutting my PC? At the same temps (and higher), the same CPU was working fine in Asus board. It would lower the multi to 20x but it won't shut the PC Off like that.

This BIOS is really buggy. I can't get consistent results from it. I lowered the BCLK, it won't post. Is 02/17 the latest DFI BIOS for this board? I am surprised DFI hasn't released a BIOS in such a long time. I have a xeon w3520, so that might have something to do with strangeness. Certainly very arbitrary behavior. Haven't seen anything like it from giga or asus.
