Prime95 Torture Test

I ran an FFT torture test over the weekend to burn in the CPU and cook the thermal compound into it. When I came back this morning, Prime95 said it encountered a fatal error. I had never encountered this before, even in overnight testing. The system runs stable, memtest86 runs overnight with no errors...

Is this a real stability issue? What does it mean when Prime95 fails?

Prime95 torture test should run forever if your system is not overclocked and correctly cooled. Since it failed and you state that your memory is not faulty, your CPU must have got too hot either due to overclocking or due to a faulty application of the thermal compound.

It's important that you state which torture test you ran, that would tell you if it's the CPU or the RAM.

I know what everyone's been wondering - 2^33634943-1 IS NOT PRIME. Now, wasn't that worth running <A HREF="http://www.mersenne.org" target="_new">Prime95</A> for a month to know?

It's the FFT max heat/wattage test.

Well, I guess that's the one testing the CPU. I got an error once with it when running my 2.4C at 250 FSB (3GHZ) with stock HS. I downed it to 233 FSB and everything was fine, don't know what exactly it means in your case if you didn't overclock. Run it a night again, it might have been a one time thing (though unlikely, worth a try).

I am overclocking to 233. The system appears 100% stable except for this one glitch. I'm going to reapply the thermal compound more carefully and try again.

If you get it again, consider either ignoring it or upping volter (Vcore) by just a bit.

Just use the computer to see if it's stable. Don't worry about doing some prime95 test. Load it up with anything that will use the cpu to 100% (windows calculator can do this).

Some day I'll be rich and famous for inventing a device that allows you to stab people in the face over the internet.

stage 1 install of gentoo is what I did after it passed a day running xp.

Gentoo is a highly configurable linux distribution. The main appeal is you can do a "stage 1" install where you boot off a live cd and then download the source code for the entire operating system and compile it yourself, with your optimizations, all for your specific hardware. The installation of the main parts of the os + gui took about 8 hours on my xp 2500+ @ 3200+ with 1 GB ram system.
