Prime 95 errors

[elm669]

For about the last 5 months prime95 has ran fine on my computer with a max temp of 46C @ 70F ambient then during the summer 56C @ 90F ambient. Only in the last month have I been having temperture problems like hitting 60C while running prime95 Which I though I fixed by tightening down the zalman that was coming loose. It brought the temp down to 54C. Well now it does this:

As you can see from the pic it fails every 48 minutes at the same one with the same rounding error yet I can play doom3 for hours and get the temp over 50C and it won't give me any errors. To top it off it's the same copy of prime95 that was working fine for months. Other than prime95 failing I notice no difference in the performance of the computer nor have any issues encoding images, mp3s, etc..

Prime95 fluke or hardware issue?

I'm off to test the ram and and redownload a new copy of prime95 to test some more.

It is a hardware issue. Are you overclocking anything? You may be able to play games fine but the error basically means your computer isn't 100% stable. Let us know if you are o/cing, if not then you have some faulty hardware.

Game rig: Athlon 2400+ mobile @ 2.5ghz @ 1.775Vcore, 512mb ddr400 nvidia FX5700le 500/435, Zalman 7000B-cu

I just reseated my zalman and dropped 5C off the cpu temp, I'm now running prime95 again... we'll see where it goes..





edit: after an hour of prime95 it hit 52C max with a case temp of 41C and it blew past the 14K part of the test... still going.

edit2: after 2 hours of prime95 the thermal paste is setting in and it's at 49C cpu and 37C case and on test 4 of the 32fft still going....

On another note this cpu now seems to have a touchy tolerance to heat..

To ensure that your computer is genuinely stable, if you have the chance run P95 for at least a day straight, preferably two. If you don't get an error in that time, then you're unlikely to have a stability issue.

WELL, It ran prime95 for 12 hours straight @ 52C max just fine with the AC running. I turned the AC off and it hit 54C and failed instantly...

So I turned the AC back on and it came back down to 52C and is still running and passing prime95 right now.

Considering the cpu could use to run prime stable @ well over 55C before I think the cpu is dying... crap...

I had to bring this thread back from the grave..

with the linux version and it's still going.

After doing some tweaking I got it to be prime stable @ above 55c again

Turns out somewhere along the line the setting in advanced features "cpu interface" got set to "agressive/overclocked fsb" I set it back to "optimal settings" and it's humming along @ 2.5ghz with no problems
