Sandy Bridge problems on Asus P8P67 Pro

I've just setup a new Sandy Bridge rig and I've already had 2 BSOD screens in the last 24 hours (not too frequent but enough to be a little concerned).

I checked the event viewer logs in Windows 7 and noticed there are several errors (about 131 in the last 24 hours) and several warnings like as follows:
>>>>>>>>>>>>>>
A corrected hardware error has occurred.

Reported by component: Processor Core
Error Source: Corrected Machine Check
Error Type: Internal parity error
Processor ID: 4

The details view of this entry contains further information.
>>>>>>>>>>>>>>>

All the above warnings are the same (affecting Processor ID 4)...is this something to be worried about?

  1. Are you overclocking?
    If so back it off and see if you still have the problem.

    Otherwise, I think you may have a defective cpu and should return or rma it.
  2. also, I've checked the blue screen dmp file and it looks like they're caused by: hal.dll and ntoskrnl.exe

    CPU temperatures are between 24-36c
  3. No overclocking yet.

    Here's what I've got:
    intel 2500K
    EVGA GeForce 460 SE
    Crucial 128 GB SSD
    Western Digital 500 GB Caviar Blue
    Corsair 8GB DDR3 1300 MHZ

    This may be just coincidental (probably is) but the BSODS began after I edited the registry so that my program files directory was on my 500GB harddrive and not on my SSD...it seems to run fine since that change, and it was a while afterwards that it BSOD'd.
  4. Ya, it came with it for Rev 3.0
  5. Use the ssd. do not bother with micromanaging it.
    I doubt that your registry hack is the source of your problem, but you might try reloading the os.

    As Psycho.. says, check for any bios updates. I think I would go with the bios on the official asus site first, if there is any indication that it will address your problem.

    Still guessing it is a defective cpu; it is rare, but does happen.

    Asus is slow at updating the bios on there site. That thread is where i get my bios for my Maximus so no worries.


    Where do they get the bios's from? I presume ASUS.

    How do you know what the bios fixes?

    Ya, I'm somewhat apprehensive of using some third part source for a bios...seems sketchy. It's running 1305 right now.
  8. I'm just wondering how common these warnings are....probably shouldn't be as common as what I'm getting...



    Any of you sandy bridge owners can tell me how many errors you're getting? Or how to get rid of these ;) ...maybe it is a bad cpu...
