No, that's entirely normal. Aside from Vcore, the BIOS appears to set warning limits of 5% below and above the nominal values, and all voltages are within those limits. The temperatures also look fine. > I was hdparm'ing some disks while, compiling a kernel and a raid5 sync > was inprogress at that time (and it freezed, of course) So, new theory required. Given you said you're not using ECC memory, can you test it with memtest86+ for a few hours? Ben.
