OC Q9650 Problem

post #1 of 6
Thread Starter 
My equipment: XFX 780i motherboard, OCZ 8GB memory, Intel Q9650, Ultra 1100 watt power supply, Nvidia GX480 video card factory o/c, running Windows 7/64. I have had this processor overclocked to 4.0 with the voltages set to auto in the bios for over a year now. Never any heating problems since all components are water cooled. The processor has never been over 50c. Now the computer freezes or I get a CTD when running FSX. This computer is dedicated to FSX application solely. Why would it become unstable all of a sudden? I have tried to set the vcore to 1.3 and lowered the o/c to 3.8MHz and it appears to be stable at that speed, but when I reset it back to what it was originally, one or two CPU cores don't pass Prime95 more than a few minutes. I am not an o/c expert by any stretch, so any advice or suggestions would be appreciated.

Thanks,

Ron Musick

What voltage was the CPU running at when the frequency was 4ghz?

Since it was on Auto I'm not exactly sure. I will put it back to 4.0 at lunch and check it.

Complete ystem specs are always helpful. You can fill them in here: Add system

It could be nothing more than after a year, the CPU wants a little more voltage to be stable.

Please do, Auto is never a good thing, it's very possible it was getting fed to many volts which can degrade your chip.

The vcore at idle, o/c to 4.005, is 1.3. Under Prime95 load the vcore is 1.27 to 1.28.
