Thread: Faulty i7 920?

I purchased my PC from ibuypower. Intel i7 920, Asus PT6 SE, 6 gigs of Corsair DDR3, 800 watt ATX power supply, Radeon 4890, initially with a V8 cooler master. I received it two weeks ago I started loading windows when a bios microprocessor overheats warning popped up. Checked the V8 two screws below the V8 were not working as well as was getting little contact with the CPU. Fixed it with fresh screws, got it warm as well as loaded windows.

Idle temps were high 44-45C. Played GTA 4 as well as recorded temps with core temp as well as it explains temps ranging from 72-87C. So I tried prime 95, and temps soared into the elevated 90's C speedily. Shut the program down, it never came close to 100% load. Set up a return for the V8. Being irritated I dropped 65 bucks on a Thermaltake heat sink at a store, (a nice one not sure what model). Reseated the CPU, new thermal paste. Idled at 38-40C, I thought great! Tried prime95 and to my dissatisfaction it rose in the 90's without coming close to 100% load.

What is going on here? Is there something worth adjusting in bios? I'm also considering checking the CPU to observe if it's flat or not, and if isn't flat should I attempt lapping it? Also I could just return the irritating thing.

I need everybody expertise on this one. Thanks!

I would first physically set the CPU voltage to 1.2 in the BIOS to see if load temps change at all.

Well I set the CPU voltage to 1.2 and it came up in windows idling at 50C, did an intel burn test 5 rounds and it never reached 90C. Highest temp was 87C. It has never been able to make it through 2 rounds without going high 90'sC and me needing to stop the test.

All in all it liked that. Still these temps are high? Any more suggestions?

Send it back Im sure it has warranty.

Yes. Good advice. Do not run your CPU voltage on AUTO. Find the VID value and set it to that. Then, if you are not going to OC, start working your voltage downward while testing for stability.
