Signs that an OC'ed CPU is near the end of its life?

post #1 of 18
Thread Starter 
I have an i7 920 that's been overclocked for at least a year(around 3.6ghz), and its been run pretty hard chewing through 1000's of frames of animation renders, sometimes with high ambient room temps.

Lately, it won't take an overclock as well as it used to, and runs about 56c idle -- which is about 20 degrees higher than usual. Even running at factory speed doesn't bring the temp back down, and I'm getting core dumps on a regular basis.

Does this mean I've worn the chip out? Could it be done that soon? I'll just chuck it and get another one if that's what you guys think. Has anyone else ever run a CPU into the ground, and did you have the same type of symptoms?

I would probably recheck the airflow, as 56c idle seems too high. Open up your case and make sure fans all work, take the fan off your heatsink and clear out as much dust as possible...

At least in my case, my old e8400 had about 2mm of dust between the fan and hsf when I checked...

Perhaps the Thermal compound needs to be replaced?

Unless it's a defective chip, I would say you just need to check your TIM and airflow.

I'll take off the heatsink and re-apply some OCZFreeze to see if that does the trick. Thanks.

It might be my watercooler. I have one of those Domino units, but I use H50's these days on my other systems. Maybe I should get rid of that thing and get another h50.

I'd agree with all of the previous, replace the TIM first, and while it's all apart check the case fans and airflow.
Unless you've been running it at extremely high voltages and it has been an unstable OC, it's unlikely the chip has degraded.

It is winter (here anyway) so chances are your heater is on, which will increase ambient temps a great deal if not careful.

I blew some dust from the radiator of the Domino cooler, removed the heatsink, wiped off the old thermal with alcohol, re-applied OCZFeeze and did a general dusting in the case. Runs at 27c idle now.
