Can anyone help me resolve my issue regarding Kernel-WHEA Event on my WinVista x64 system? I am having the same error even after the clean installation of WinVista x64 on my 2 x AMD Opteron 280 system.

Can anyone help me resolve my problem? Or at least what have gone wrong? I desperately need your input.
Thanks in advance.


Followings are the error message I get:

Here's what Event Viewer says:

The processor detected a hardware error somewhere in the machine, and Windows logs this event whenever it occurs. The hardware diagnostic tools (like MCAT) will tell you more...


OK, so you've either got a bad processor on slot 0, or bad RAM in the box. Have the hardware vendor run a diagnostic check, because this could very well be a bad processor (almost all MCE are).

Thanks for your input.
Well, I did run the manufacturer provided diagnostic tool to check my CPU and RAM, but all tests passed without any problem.

Event12, Kernel-WHEA error seems to appear only when WinVista boots up. And while Windows is running, no error shows in event log.
However, Event12, Kernel-WHEA error does get logged even after the clean installation of WinVista, but as I have said only during the boot up process.

It's very difficult to ask for the warranty service for my WinVista error log since my workstation manufacturer supports WinXP only.
So can anyone tell me how I can pin down what part of my Hardware has gone wrong?

Thanks in advance.

I did run some more tests. And here's what I've found out:

Swapping CPU1 to CPU2: same error message
Repositioning DIMMs with each other: same error message
Removing DIMM's for CPU1 (with rest of 2GB installed for CPU2): no error log
Removing DIMM's for CPU2 (with rest of 2GB installed for CPU1): same error message.


So it seems that neither CPU's nor DIMM's is causing the error.

Would it be due to faulty motherboard?

The part regarding having DIMMs installed for a specific socket leads me to believe that yes, it could very well be the mobo.

Thanks for your comment.
I have requested warranty service and my mb + dimm's are scheduled to be replaced.
I will follow up after I get them replaced.
