Computer basically shuts off when overclocking and stress testing.

post #1 of 4
Thread Starter 
Whenever I try overclocking my FX-8350, then running IntelBurnTest, the PC shuts down completely on me after a small amount of time running IBT. I have an aftermarket heatsink, the Cooler Master TPC-812, in push-pull configuration, which should be keeping the temps in a safe range. At first, I thought it was a power supply problem because my PC restarted whenever I overclocked my FX-8350. However, replacing the PSU from an Antec HCG-750 to a Corsair AX760i ruled that out. And replacing the old, Antec Formula 7 thermal paste, with new, Antec Formula 7 thermal paste didn't fix the problem. My motherboard is a Gigabyte GA-990FXA-UD7.

Other than the inability to overclock without the PC shutting down on me, the PC is fine. I can run it at stock. My Radeon HD 7970 can overclock fine, albeit it's not a good overclocker, which likely rules out a PSU problem.

Any thoughts on what's wrong? I've ruled it down to these possibilities. There could be a faulty temperature sensor. There might not be enough pressure on the CPU to give efficient thermal contact between the CPU and the heatsink, and I should replace my Cooler Master TPC-812 with my Xigmatek Aegir. Which one is it?

Do you know what the temperature of your cpu is when your computer restarts? If it gets well over 60 degrees then that could be the problem.

Also, is your psu getting enough ventelation? Your psu might be overheating.

PSU shouldn't be an issue, it was replaced two weeks ago.

Regardless, I figured out the problem. There wasn't enough pressure on the CPU given by the Cooler Master TPC-812. I'm able to get much better temps with the Xigmatek Aegir, and i assume that's because it puts more pressure on the CPU, allowing more metal and less thermal paste to be together.

CPU temp still goes over 70C and Temp 3 reached 89C during IBT stress testing, however. But I backed down the voltage from 1.4875 V to 1.4375 V and it's still stable. Still, CPU temp still went over 62C while stress testing at 4.7 GHz at 1.4375 V.

I was about to say 'monitor your temps while benching'.

This Hyper 212 Evo can be EASILY overwhelmed with any sort of voltage bumping. I need to dremel my case and reinstall this H100 tongue.gif
