My colleague told me that one of the RAM chips/slots after the first four (possibly 2A or 2B) might have failed, resulting in the remaining memory slots (3A and 3B) not being checked. Can anyone confirm this theory? Is there anything else that I can try before contacting HP support?
Thank you in advance for your help.

Re: rp3440 incorrect RAM amount reported
You can check the memory status from BCH to menu as
BCH -> IN -> ME
Detailsed FRU infomation and logs in could be found in
MP -> CM -> DF
MP -> SL -> E

Re: rp3440 incorrect RAM amount reported
So, my next question (and hopefully the last for this forum) is how do I locate a DIMM or DIMMs that were software deallocated?
Thanks again...

Re: rp3440 incorrect RAM amount reported
Even from the event log , the locations of DIMMs could be determined.
Refer the following manual as well for memory conifgurtions, rules, and slots identifications etc. at

SolutionIf you examine the logs prior to the MEM_DIMM_HW_DEALLOCATED events, you may see earlier errors that clearly identify the DIMM with a problem, as in this example where DIMM 3B is suspect ...

When a single DIMM is replaced within a quad, it is necessary to use the 'pdt clear' command at the BCH service menu, or rotate all the DIMMs in the quad to new slots.

Re: rp3440 incorrect RAM amount reported
In the iLO's Event Logs, I set the filter level to 3 (warning), so that's why I didn't see errors prior to MEM_DIMM_HW_DEALLOCATED. I've set the filter to 2, and then I was able to pinpoint which DIMM was having problems (MEM_CORR_ERR). I guess I can't assume that major events like this must be level 3 and above.
We replaced the single failed DIMM, and the server seemed to freeze up during POST. So, we took out all the four DIMMs in the quad, rebooted the server and noticed that the PDT was already cleared at this point. We put all the four DIMMs back in the same slots they were taken out from, and everything now works just fine.
So, I assume that when Julian mentioned the running of the 'pdt clear' BCH service command, that this must be done BEFORE the single DIMM is replaced?
Thank you all for your contribution. The problem has now been resolved.
