Is the overclock stable enough after over 1 hour of prime95 blend? - Page 2

post #11 of 19
Honestly, after passing Prime 95 blend for 24 hours, you should fold with your rig for a day, and if it doesn't BSOD, it's another safe measure. I recently started folding, and my previous OC had passed 24 hours of Prime, as well as 25 x 25000 link runs, and then it BSOD'ed when folding. So I had to tweak that OC further, and it's pretty solid now.

No seriously, what can I conclude after a longer run of prime95 without crashes?
You can conclude that it is all relative. You can be 12 hours stable in Prime95 and crash in IBT or LinX. Vice versa also applies. This is what happened to me when I was testing at 4.0 GHz with my old Gigabyte motherboard. I also had a situation when I passed 12 hours prime, IBT, LinX and crashed 5 minutes into FSX

These stress programs are more of a 'guideline" to see if you are on the right path to stability. If you pass P95, IBT and LinX, run CineBench, SuperPi, play a few games and if you don't crash you can say you are reasonably stable. Put it to fold, at least one -bigadv unit and you are stable for 24/7 activities.

How do I know my current overclock is stable? I folded for more than 1 week during the CC doing -bigadv after bigadv for OCNChimpin. If that is not proof of stability, I don't know what is.

Well, it just rebooted, after 2 hours and 39 minutes prime95 blend. What would you suggest? Increase the volts further, lower the overclock? Temps were 56°C high in "Core Temp 0.99.8".

Not in my opinion, i went over 18 hrs prime on my overclock, and its still purring like a kitten. Some say long runs of prime are bad , but imo most processers will still outlive there usefulness even with all the overclocking/testing.

i would say your close, if it went two hours, Just increase within the safe limits of your cpu.

56c is that your cpu or you cores?

The program is called "core temp32" so I guess it's the core temp.

Yes, i have both installed. Didn't know though that the os is important for the stresstest. I exclusively used xp for the last few months but may start using 7 again.

yeah the os is important.
its easier to oc on xp.
its easier to oc on 32 bit.
as an example, i oc as an unlocked quad at 3.5 on 1.45v with 32 bit 7 installed. when i switched to 64bit, im locked on a triple core doing 3.4 on 1.45v
they say its easier to get higher oc on xp than vista or 7 but i dont know. ive only run 7 since i put this together.
