Sam, i cant resist, delete this if you like, or tell me to in the return PM, but:
With the exception of Skip and maybe 1 or 2 others, your overclocking very sloppily. I do not mean to be rude, but jumping from 35c to 47c from idle to load (1st or 2nd poster) is entirely unacceptable of a temp differential.
You guys NEED proper cooling, stock heatsinks do not cut it when doing 30%+ overclocks. I agree that there is something fishy going on, but you guys are being careless. Thats entirely your perrogative, but I'm just letting you know, you need to not just watch the temps but the differentials and changes as well. Also, loosing more than .2vcore when going under load is walking the line, im talking dangerously close. And be careful with the voltages.
I ran my old school XP1600+, which I still have now, at 2.3vcore 1.85ghz for almost 6 months, but it was kept at 40-43c with heavy custom watercooling. You guys are playing in dangerous waters (for the CPU's) and taking huge risk's with your chips. Overclocking isn't just pop a chip in with everything stock, crank the vcore mad high, and start bumping the FSB 10mhz at a time. Its about precision, thoroughly testing and burning the CPU for at least 12 hours per setting checking for errors, runing memtest86 for a couple hours each frequency bump to make sure you arent generating errors (which will often not crash the comp, but write erraneous data back to your disk and send it to the CPU), and use prime95 to test system calculation outputs.
Sorry for ranting and disobeying Sam's thread rules, but I had to post this.
