Quick questions

When your saying your CPU temp > 60 are you talking about the temp of teh cores (read by CoreTemp or such program) or the reading the BIOS/ASUS programs give you?

Also I'm suffering random crashing when doing more than 70% total load on a Q6600. It happens at 3030Mhz, 3150Mhz, 3300Mhz. Basically any speed i set it to. i can boot & run windows Orthos whatever. but if i stress all 4 cores after awhile the system just reboots. same thing happens at NB voltage of 1.4, 1.45 or 1.5. exactly the same so i dun think thats the problem. I dun like going past 1.475 Vcore cos my Core temps get to hot. & its happening even at 3Ghz when it will run 3Ghz Orthos on 2 cores stable @ 1.38125 V. so i dun see why i would need a full extra volt & then run into over heating problems. Also tried ram at all range of speeds. Currently @ 965Mhz 4-3-3-8 timings @ 2.5V. But i am getting the crashing issue even at 800Mhz 5-5-5-15 @ 2.2 volts. so i really doubt ram is the problem.

Bios is 602

could vDroop be an issue?
if not any other ideas?
