I have an AMD Athlon X2 4000 CPU and iv being testing it at speeds of up to 2.5ghz, but the thing is i am only using stock cooling, i did a stability test for 30min and the highest temp my cpu got to was 42 degrees. So my questions are, is that a reasonable temp, and is 30min long enough to get a good idea of the systems stability? Oh and another question, sometimes when i overclock my processor and i restart my pc later (about 5 hours) boot fails! I lower the clockspeed and everything works fine, so why was i able to run my PC at that speed before but later own it doesn't boot?

Yea i would say 42 is ok. 30 mins is alright for a stress test maby you could do an hour and see. And for your overclocking it could be 1. it overheats or 2. its an unstable clock.

Run Orthos or Prime for 8 hours-that is generally considered to be stable.

Do you think it could be my ram thats the reason for it not booting? Im saying this because i got the cheapest ram i could find.

Yes, it could definetly be. I underclocked my RAM and increased my clock and it boot. that's how i got my 4000+ 2.4 over 3.0. You should play arround with frequencies.

Awesome, what can i use to underclock my ram? My bios doesn't let me keep the ram at stock frequencies and there are no other options for changing it.

Sorry, no help there, I use my BIOS. You would probably need to change it before Windows booted up anyway so I don't think any program would work.

"A processor should be tested for a few hours minimum, ideally it should be tested for a full day."-Neoseeker

" Stress tests should be left for a burn-in period to test stability, preferably 12-24 hours."-Techspot.com

"One of the ultimate stress tests is Prime 95. When you think your system is stable, run the blend torture test for 12 hours and see if you get any errors."-WikiHow

"Eventually increasing the voltage will have little effect on increasing the FSB. At this point run a full range of tests and increase the duration of your Prime testing to 8 hours"-overclockers.co.uk guide to overclocking

Most of the best guides on the web dont specify less than 8 hours. Any less and it is not considered a stable system.

Yea thats true, ill be getting new ram soon anyway so hopefully that fixes the probelm, thanks for the help.
