Why does my i7 only have one core? [solved]

post #1 of 36

A little back story: My i7 completed its last bigadv unit for CC, so i moved it and the motherboard it is in back to my main rig. All 8 threads worked fine before i moved it. Booted up on my main OS (as opposed to the folding OS i had been running for the past 10 days), and now it only shows one core.


I already tired:
-msconfig (only lets me enable 2 threads)
-Bios (only lets me enable 2, gives me the option of auto, 1, or 2, all have the same result)
-Flashing bios, same problem


I am out of ideas.

Did i break the CPU?

Did you pop off your heatsink and take a gander at the cpu itself? I'd check for bent pins, etc. Hopefully it's just a bad seating!

I didn't remove the CPU from the socket when i moved it between rigs.

Is it possible to bend pins with a cpu in the socket?

Any movement of a motherboard could potentially cause your cpu to unseat. I have had it happen to me before when moving. I doubt the pins would be bent, but it doesn't hurt to check.

this is scary. my only suggestion would be to try it in a different motherboard, or at least re-seat the HSF in case that got jostled. It could be something completely odd like that.

There must be some BIOS option that disables/enables cores..

Check your motherboard's manual for info..

I doubt it that it has anything to do with a bent pins..

CHEERS..

I just reseated it after i checked the socket for bent pins.

Found out my TIM was pretty badly applied, so i fixed that while i was there.

didn't find any bent pins though.

I might end up running to fry's tomorrow to see if i can pick up a cheap board to test with.

I spent the better part of 8 hours staring at the bios of this board (benchmarking session), And now I cannot find anything other than what i have already tried that relates to active cores.

There is an option for "active cpus" and it only lets me set it to Auto, 1, or 2

Does it still work in your other OS? This could solve whether the problem is software or hardware related.
