DL585 G7 Uncorrectable Machine Check Exception

The server rebooted unexpectedly this morning. It is running 2008 R2.

From the system management homepage:
Uncorrectable Machine Check Exception (Board 0, Processor 1, APIC ID 0x00000010, Bank 0x00000004, Status 0xBA000000?F0F, Address 0x00000000?, Misc 0xC0040FFE?)

Followed by 300 of these:
An Unrecoverable System Error (NMI) has occurred (System error code 0x00000032, 0xA122088A)

Then the server rebooted.

Any ideas or suggestions?
Thanks,
Travis

Try to remove memory modules to minimal configuration, also remove BBWC cache modules.

Please update to the latest SystemROM 2011.01.29 (15 Apr 2011), it contains some fixes which may help:

Resolved an extremely intermittent issue that can result in a system reset or operating system crash (such as a Windows Blue Screen, Linux Kernel Panic, or VMware ESX PSoD) when the system is under heavy I/O load. This issue is typically seen with systems configured with a large amount of optional PCI-express expansion cards.

Re: DL585 G7 Uncorrectable Machine Check Exception

Does the DL585 G7 use the same architecture as the G5's ? Not completely but in terms of memory..

That the "memory controller" or (whatever it was called), was in the CPU? So that memory errors could come from a faulty CPU as well?
