I'm getting errors from WHEA such as the one below. I have an ASUS z9-pe ws motherboard, with 2 E5-2687w processors. When using just one processor, I never see the errors. When using the second processor, too, I see the WHEA warning occur around the same time I get a system hang. No OC being done.
Also, my second processor's temperatures look wrong for one of the cores. Is core 1 normal? Room temperature is 69F. Core1 can't possibly be that low. Perhaps it's bad?
Temperatures:
Core0: 91F
Core1: 55F
Core2: 84F
Core3: 68F
Core4: 75F
Core5: 77F
Core6: 79F
Core7: 73F
A corrected hardware error has occurred.
Reported by component: Processor Core
Error Source: Corrected Machine Check
Error Type: Bus/Interconnect Error
Processor APIC ID: 32

Are both CPUs from one stepping/SKU or from different? Have you a latest BIOS in mainboard?

Yeah, I've double checked stepping to be the same. Here is what CPUZ reports for both (I remember checking the physical processors to be the same, too):
Family: 6
Ext Family: 6
Model: D
Ext Model: 2D
Stepping: 7
Revision: C2
Latest BIOS for the board has also been verified to be installed.

I suggest you to raise an ASUS support, it looks like defect mainboard.

Hello Nimesh,
I have some recommendations for you to try:
- First and as mentioned by JFFulcrum, confirm that the two processors have the same core stepping (spec code). As you can see it the following link, there two steps for this processor, C1 (SR0GX) and C2 (SR0KG): http://ark.intel.com/products/64582/Intel-Xeon-Processor-E5-2687W-20M-Cache-3_10-GHz-8_00-GTs-Intel-QPI# @ordering http://ark.intel.com/products/64582/Intel-Xeon-Processor-E5-2687W-20M-Cache-3_10-GHz-8_00-GTs-Intel-QPI# @ordering
- If the two processors have the same Spec code then try one unit at a time in the same CPU socket of the board and compare behaviors.
- You can also run the Intel® Processor Diagnostics Tool using one CPU at a time. This tool will report problems or errors if one of the units is malfunctioning. You can get the Intel® Processor Diagnostics Tool using the following URL: http://www.intel.com/support/processors/sb/CS-031726.htm http://www.intel.com/support/processors/sb/CS-031726.htm
If you confirm that only one processor is giving issues you better request for warranty. Use the following link to choose the type of service you want and the correct contact center for your area: http://www.intel.com/p/en_US/support/contactsupport http://www.intel.com/p/en_US/support/contactsupport
