Proliant Server

Since I've updated my Proliant ML350p G8 with SPP 20170401 I'm having problems with the memory. Sometimes it does not recognize the memory correctly and then if I reboot it goes back correct until the next reboot. Sometimes I have to remove one memory stick and put it back in to have it work correctly.

Is it possible to roll back this kind of updates?

This is very odd.

I'd take Michael's suggestion.

Pull all memory sticks + clean contacts with alcohol. If you have a memory connector cleaning tool, clean the connectors too.

Reseat memory, till you get a clean reboot + then flash firmware with any updates.

If you're firmware is outdated, you may be dealing with a bug that's been fixed.

Firstly I would recommend powering the server off, removing and re-seating the memory. If you have multiple processors, can you please ensure it is balanced between the both of them, and their channels.

Can you check the iLO & HP System Management logs once booted up, to see if there are any errors displayed here on the dashboard and IML Logs?

HI and thanks for the fast answer.

I did remove the memory and make sure there is no dust or something. I reinstalled them. Restart the server and everything is ok until I reboot the server. In the ILO I have memory degraded and an error of the memory in slot 9 for example. Remove and then reinstall the memory and the issu will occur again at the next reboot.

If you move the memory around does it still show that it is the same socket or does it follow the faulty memory module around?

If it follows the memory around - potentially would need to look at replacing this.
I would clear down CMOS with maintenance switch 6 , then on next boot it will reconfigure RAM speed to match what the DIMMs require. Sometimes BIOS updates change presets to silly values and resetting CMOS resolves that. Sticker on inside cover should tell you where the maintenance switchblock is, may not fix but it costs nothing to try.

Reseats rarely if ever work.

Are you using your vendors official RAM ?? if not this could be a nothing issue as often the servers cannot detect other brand memory.

The HP Boss is late to the party here ;)

This is a vendor level issue IMO, log a call with HPE.

Also just curious what you mean by "not recognizing ram"
In Virtualization or Physical OS is the memory visible and usable in performance graphs?

I am sitting on 2 X old Poweredge R710's at the moment and they regularly post memory errors but work away fine and use memory as standard.

Also refer to HP diagnostics to determine memory faults.
