i7-920 faulty?

post #1 of 5
Thread Starter 
Hello fellow enthusiasts!


Is it possible for an i7-920 @ 3.8Ghz stable for 6 years to go faulty and still pass 8hrs prime95 testing? I'm noticing some CPU bottlenecking in CPU-intensive games. My CPU fan died for the 2nd time and my PC shutoff automatically as it happened. The thermal paste I cleaned out was actually brown and yellow, which I've never seen before.

My motherboard is an Asus p6T vanilla. Could that incident with the CPU fan dying for the 2nd time damaged my motherboard or RAM? CPU temps are fine, but could a CPU be faulty while also passing 8hrs of prime95 testing?

P.S. RAM passed several tests.

I would think it much more likely the motherboard is bad, but anything is possible.

That is exactly what I was thinking because I was in this same situation 6 years ago where I was replacing every piece of hardware... until I changed the Mobo and PSU to fix the FPS issues I was experiencing in CPU-intensive games.

My PC has been running right now for 48 hours without sleep. I was playing a game a few hours ago and noticed the CPU bottlenecking again. I also noticed I was getting choppiness in the game despite having over 100 FPS. Then someone in the game told me this trick, which is to go into task manager and click the game.exe and uncheck core 0 and click ok. Then check core 0 again and click ok. That fixed the choppiness and increased my FPS a bit. Now my CPU was behaving "normally" for this game with the occasional bottlenecking. I ran OCCT test after I closed the game and it found errors within 30 seconds. I thought that was very weird so I restarted my PC and did the test again and it passed 3 hours with no errors.

Is there a way to check if the mobo is faulty?

A chip that has been running overclocked for 6 years and then has a thermal catastrophe could very well now be damaged (I am reluctant to say 'faulty' since it was running outside of Intel spec). CPU stress tests never test all the functions of a CPU, which is why no stress test is really perfect at predicting the stability of an overclock.

If you experience crashes, there is a chance the CPU is the issue. Of course, it could also be totally fine, so if and when it does crash, check the error message and the dump files to start figuring out what's going wrong.

There is always the 6core 32nm option for your X58 board. I would look into a W3680, or an X5675, but make sure your board is compatible and your bios is updated first.
