Overclock failing?

post #1 of 9
Thread Starter 
I have a E8400, I used to have it clocked at 3.8ghz but now my computer cant handle 3.6ghz. Its been stable at 3.8 for at least a year but my computer just crashes. Is their any way of telling if its the CPU or the motherboard. I have a old EVGA 680i LT. (not in warranty)

Might just be early CPU degration if you haven't messed with any other settings.

What exactly happens to your computer? Crashes as in hard locks? Blue screen? Does not post?

Got about 6-8 e8400 builds out there I've done. All are running at 4ghz for the past 3 years with cheap air coolers and they are all still working fine. Most are on Evga 680i boards. No Lt tho. 2 are on 780i and 1 on 790i ultra.

Not sure why yours is having a problem. What settings are you using to get your overclock?

Has the same issue with my e8400 after about the same timeframe had mine at 3.2. Once I lost the stability with it the i7s were out so I handed my old pc to my dad with a lower clock and I started a new build with the i7 set for my current pc. So you are not alone and I would agree that it is most likely the CPU breaking down.

Some times blue screen and it would dump my memory. Some times it would just freeze. Once it froze and did the repeating studdering audio thing, then un froze and i had no audio.

I keep a zalman 9700 so i have ok temps. I cant get it up to 4.0ghz because my motherboard is a LT.

That sucks. That's why I wish people understood that you don't get great overclocks on cheaper boards. There's reasons why the better board cost more. The overclock more.

Like I asked before, what settings are you using to get your overclock. Can't help much without that info. Got a bios pic or what you changed? Whats the VID for your chip?
