dino, I think the ambient temp was around high 20's celcius (or about low-mid 80's F) at the time.
And yes, for the P5B deluxe, too much voltage on the NB causes the bug. Usually 1.55 and 1.56v settings. 1.45v is not bugged. It is maybe a bug in intel NB, as they released the C2 revision and new C1 ones without the bug I think. Or a bug in ASUS PCB layout corrected on new batches (as My new C1 revision is not buggy while my previous same C1 had that bug)
