RX4640 Memory Config Error

Mark_Woodward — Mon, 18 Jul 2011 08:40:10 GMT

I have recently powered on my RX4640 server to find that it stops with the system error led flashing red and the "Memory Config Error" diagnostic LED lit. No other diagnostic leds are lit (except "check event log").

No memory has been added or removed, I have tried reseating all 4 dimms and even changing the order of them but the same error persists.

The output from the MP system event log is show below - this remains exactly the same irrespective of the order of the dimms - the MEM_CHIPSPARE_DEALLOC_RANK message always refers to the dimm in slot 0D even when I change the order of the dimms.

The only thing that has happened is the battery on the main board has failed - this is now replaced but the error persists - could the NVRAM be corrupt - how can I reset this?

Anyone any ideas? - the system log output is shown below.

This indicates, there was some memory issue for which it had de-allocated the rank. Re-seating was the first option which you have already tried out. One of the module out of 4 may have some issue. If you have spare memory DIMMS, you can try swapping them one by one.

You may try the information on HP Guided troubleshooting at

I am thinking this is more likely a memory carrier issue (a hardware problem resolved by replacing that component). The fact that you can change DIMMs around without changing the error location supports this. Since the quad is being deconfigured and you only have the 4 DIMMs, the system has no memory to use.

If you dont have maintenance for this system, perhaps as a cheaper workaround you could install 4 more DIMMs? Bank 0 would still fail, but the system may be able to boot with bank 1 operational.

Thanks all,

I've managed to get hold of another 4Gb and unstalled these in place of the old ones - It all works now.
