sangwooksohn Posted December 10, 2007 Share Posted December 10, 2007 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: Event12, Kernel-WHEA Machine Check Event reported is a fatal Bus or Interconnect timeout error. Memory Hierarchy Level: 3 Participation: 0 Request Type: 3 Memory/IO: 0 Address: 30422400 And here's what AMD Mcat says: Event Source 0 Processor Number : 0 Bank Number : 0 Time Stamp (0x): 01C83B55 755106C4 Error Status (0x): D4384000 00000833 Error Address (0x): 00000000 01D03580 Error Misc.

Memory Hierarchy Level: 3 Participation: 0 Request Type: 3 Memory/IO: 0 Address: 30422400The 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...And here's what AMD Mcat says: Event Source 0 Processor Number : 0 Bank Number : 0 Time Stamp (0x): 01C83B55 755106C4 Error Status (0x): D4384000 00000833 Error Address (0x): 00000000 01D03580 Error Misc.

Have the hardware vendor run a diagnostic check, because this could very well be a bad processor (almost all MCE are). Link to comment Share on other sites More sharing options...
sangwooksohn Posted December 11, 2007 Author Share Posted December 11, 2007 (edited) >>clubertiThanks 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.

sangwooksohn Posted December 15, 2007 Author Share Posted December 15, 2007 I did run some more tests. And here's what I've found out:Swapping CPU1 to CPU2: same error messageRepositioning DIMMs with each other: same error messageRemoving DIMM's for CPU1 (with rest of 2GB installed for CPU2): no error logRemoving 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?

cluberti Posted December 16, 2007 Share Posted December 16, 2007 The part regarding having DIMMs installed for a specific socket leads me to believe that yes, it could very well be the mobo. Link to comment Share on other sites More sharing options...
sangwooksohn Posted December 17, 2007 Author Share Posted December 17, 2007 >>clubertiThanks 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. Link to comment Share on other sites More sharing options...
