What is broken: CPU or MoBo?

post #1 of 12
Thread Starter 
OK, the end of my experiments with overclocking is that I found out that either something was already crappy from the beginning or I destroyed it with massive voltage changes.

After I got all those freezes and could not get any stable OC, I resetted everything on factory settings, just to find out it simply does not pass a hardware test anymore.

prime95: Small FFTs lead to instant restart after starting the test, large FFTs slow the machine down to unusable and unreadable.

With my overclocked settings I had difficulties restarting, had to switch on and off all the time to even see the self test screen on startup. This was the only problem which was gone with returning to default settings.

I don't really have the money to replace BOTH components...in fact, I dont even have to money to replace the CPU, so I just hope its the MB.

Does anyone know how to tell which part is damaged?

About RAMs: after these 20+ attempts to restart, memtest found some errors, but after a clean restart, they were gone...also, replacing and changing the two RAMs did not change anything, and I don't believe I fried them both. I am only a bit confused that they are labeled 1066 RAM and CPU-Z and all the other programs told me they are 800.

try pulling the battery and see if that does anything, it should restore to defaults, what are your temps in bios?

OK Hardware Monitor says:
CPU Temp: 34°C
MB Temp: 39°C

I used the "restore default settings" function to do that, I'll try that with the battery.....

It would probably help to unplug the power connections from the motherboard when resetting the CMOS

Weird, so your running everything stock? No N-tune or anything?

I'd love to tell you, but with small FFTs the machine restarts instantly without giving things a chance to heat up.

I just ran another large FFT test which was quit after a few seconds on three of four cores with a message that "rounding was 0.5, expected less than 0.4"
Trying small FFTs froze my system up.

Exactly, I quit all OC because of that freeze problem, so I think I fried something during that. What is still a bit odd because I never pushed my CPU beyond 60 °C. Only thing I can imagine is that I toasted my NB.

Maybe your memory is acting up, try running memtest off a cd on bootup.

Is there any memtest on bootup for x64 systems?
