Overclock suddenly unstable

post #1 of 26
Thread Starter 
My overclock ran smooth for roughly 6 months. All I do is game and web browse and my temps were very safe even when gaming would not run hotter than around 45-47c. Now around last week it suddenly would lock up and freeze. I switched to default settings as I did not have time to mess with it. Messing with it today and slightly raising the voltage does nothing, either does lowering the overclock. Any idea on how to continue further in figuring this out?

How much voltage were you running? Sounds like your CPU might have degraded. Try running Prime for about 8 hours if it doesn't crash then your CPU should be fine. I think it could also be a failing hard drive.

So I am assuming that with default settings you are running 100% stable?

I agree with VitalShot... the CPU may have degraded...

Do CPUs degrade faster the higher you OC them? Or is it mainly an issue when voltage is increased?

yes i'm 100% stable with default settings. If the cpu degraded does that mean I can no longer OC it even a little bit? I was running 1.493 volts @ 4.8ghz

when you suggest running prime, do you mean with stock settings? How can I test my harddrive?

No I mean try it with your overclocked settings, if it passes Prime for at least 8 hours then your CPU probably is not the issue. However 1.493v is a lot for an Intel CPU, so it may have degraded. And for the hdd I believe Windows 7 has a built in utility that allows you to test for a failing hdd.

Thats the thing the overclock is now so unstable I can't even boot. It went form perfectly stable to flat on its face in about a day.


Also to clarify.

My sig rig is not my current rig.

The problems are with my FX8350

1st of all I don't believe that many mobo's can be precise to the 3rd decimal of a Volt, so...what your CPU was fed might be a bit more (or less) than the BIOS setting.

Yes CPUs do degrade, mainly with too many volts, not GHz, when overclocking.

Usually you can keep it running stable at the same speed by pumping a tad more volts (which might degrade it even further), or decrease some settings - either cut back some volts and GHz, or make your memory timings less aggressive.

Running prime @ mem or CPU heavy modes will let you get more educated guesses on which component is failing first (memory or CPU) for you to relax the appropriate settings.

hello,
I would turn off all the advance cpu setting tab, cool and quiet and the rest, disable the turbo core manual your load line and voltage and then see if it stable at its turbo core speed of 4.2.

the voltage should be real low @ 4.2.

as for odd voltages, mines not right either, its not the voltage alone its the cpu load line that makes this setting.

underload I get v-droop down to 1.22v from 1.32v with no load line, my load line add's 0.6v constant on top to keep it up, each level is 0.2v if you wanted to know.

throttle = 2800 at 1.22v oddly enough.
