First time OC. I read up a bunch before I did this and followed a basic guide. I'm hitting temperatures of over 100 C! My computer seems to be running fine so either my MOBO is fried and I don't know it yet, or is something wrong with my temp sensors?
Here's what I did:
1) I changed the FSB to 333 and the VCORE was set at either auto or 1.23125 to 1.25v to get 3.0ghz overclock. According to this guide: C1E Disabled, Vanderpool Disabled, Speedstep Disabled.
2) Ran PRIME95 Blend test for a few hours
3) Speedfan was registering CPU and AUX temperatures around 35 at first but after about 2 hours it spiked to around 120c. That's impossible isn't it? I was running HWMonitor at the same time and it listed CPUTIN and AUXTIN temperatures hitting 0C minimum and 120C Maximum. WTF? That's a range between freezing and boiling water!
PRIME95 tests all passed for hours, no failures ("round off checking" checked on). My computer seems to be working fine so far, no funny smells from my MOBO. So...what's the deal?
All 4 Cores run below 52C under Load
All are brand new parts except for the video card:
asus P5Q-PRO Q6600 (G0 Stepping)
two WD 640gig se16 (WD6400AAKS)
8 gigs of Mushkin HP2 6400
Xigmatek HDT S1283
It shouldn't be that far off, that's wacked. I suspect the mobo. Tcase will need to be calibrated, if you can get it in range. In any case, with Tjunction at 53c max under Prime95 small FFT load with Core Temp, you are good.
