hey guys,
Today I was overclocking my i7 950 (D0 stepping), and I was at 3.6ghz with a voltage of 1.25v (vcore) in BIOS, and I ran prime blend test for about 10-15mins, without any issues, and my core temp stayed under 63-64C on the hottest core. Then i bumped my multiplier from 21(175mhz base clock) to 23 (also 175mhz base clock) in order to reach 4ghz, and disaster. It booted to windows and after 2-3min after I finally launched cpu-z it read a voltage of 1.5v! I shutdown my pc, and haven't yet turned it on. The system was in idle, I didnt even run prime95 yet, and temperatures read in the high 50's (core temp)!
How is it possible that I had 1.25v in BIOS and then suddenly have 1.5v in windows, isnt the system supposed to crash if it has not enough voltage, instead of just overvolt? The core voltage was manually set in BIOS, while the others, except vtt were and ram, were set on auto.
My system specs:
i7-950 (D0)
evga x58 3sli
6gb 1600mhz
750watt corsair
Cooling:
120mm rad
danger den water block
swiftech pump
Could my CPU be damaged?
What should i do next?
Thank you in advance
