CPU Requiring And More Voltage!!!

post #1 of 34
Thread Starter 
I've been running my CPU @ 263 x 9 = 2367MHz for many many months now.

A few months ago my computer started randomly rebooting and freezing up. After going through hell, i decided to give Prime95 a shot, and what do you know? I get errors.

So i turned the voltage up, Prime95ed fine and have been well for a month. Now the same crap is starting up. The computer is rebooting during load and Prime95 is showing errors. My CPU is needing more voltage again.

My PSU's rails all seem pretty darn stable in the BIOS.

What is this a sign of?

Probably just your CPU beginning to fail. I have heard in some cases that overclocked CPU's have a habit of working great at one voltage and later on needing more voltage as they begin to fail. This happened on my 4000+ a while back.

Try with another PSU then take a multimeter to it.

Well, here are the specs of my OC:

263 x 9 = 2367, 600 HT, 6:5 mem, 1.625 vCore, 2.8 vRAM, 1.5 vAGP.

The CPU used to only require 1.575 vCore, then when the problem came up the first time i ended up needing 1.625 to get it stable. Now i'm working on seeing what i need to get it stable this time or if i can get it stable at all

So it's probably the CPU itself and alone?

i would not go that far until you test it in another system.

Probably CPU or PSU failing. My first guess would be the PSU seeing as it's a raidmax.

I have no other system to test this CPU on; it's a 754

And for testing the PSU on another system: the only other computers i have are junk (a computer with a measly Sempron and MX400). The only other PSUs i have are junk too (generic crap).

How would you recommend i go about diagnosing this problem?

It's a raidmax, but the the voltages on the rails have always been pretty stable. But that doesn't mean it's perfect though, right?

hmm, that sucks.
Try one of the cheap PSU's and see if they boot up

There's other stuff like noise in the lines and power ripple. Cheap PSU's just cause problems with everything.
