NMI Parity Error

NMI Parity Error



We have a DL380 G5 server running Windows 2008 R2 SP1, with the latest HP Firmware Update DVD and ProLiant Support Pack -


This is a clean install, with only the Hyper-V role installed. We followed the HP Teaming/Hyper-V PDF to install in the correct order -


1) Install Windows

2) Install PSP minus HP NCU

3) Install Hyper-V

4) Install HP NCU


We have 3 add-in NICs - 2x HP NC364T and 1x HP NC380T, and we have 5 SLB teams setup.


However, were are persitently getting an NMI: Parity Check / Memory Parity Error, as detailed here


We have also had the fressing on Completing Installation... in the same article.


However we have the P400 controller with BBWC with 3 disks plugged in (RAID 1+0 with Hot Spare). We have 3 other identical servers configured in the same way without issue (we have a Hyper-V cluster). Our support company have changed the motherboard without success, and they are at a loss.


It's been on-going since December 2011 now so it's getting beyond a joke - we can't delpoy this server at the moment.


What is the cause of this problem. Right now, we have the 3 add-in cards removed and that hasn't made any difference.


Please, please somebody help us!

Re: NMI Parity Error



maybe you have an actual problem with the memory or a memory module?


Run memory test (boot machine on a disc with memtest86 for example).

There are also diagnostic tools on the HP smartstart disc.


Check for errors in IML / ilo log.


You may also want to compare the memory setup between this server and the other servers.

Where DIMMs are installed etc, types/spares/, setting in RBSU. Compare with quickspecs that the DIMMs are installed in the correct places.
