Proliant DL380p Gen 8 RAM not fully usable with Windows 2012 R2 x64 Standard
Hello, so the title says it all. We recently purchased 4 Proliant DL380p Gen 8's and each of the has the same issue. They each are running x64 Windows 2012 R2 Standard with 64 G of ram installed, but each reports only 48 GB usable if you view the computer properties.
I've tried updating any drivers that seem like they could possibly be relevant, including BIOS, etc but it doesn't help. All are fully patched through windows update. Any idea what it's going to take to make all 64 GB of RAM accessible on these 4 servers? Thanks

Oh, and I didn't ask - what's reported by the HP ILO? This is a great place to look because it has NOTHING to do with Windows. If the memory in the ILO is being reported as 48 gigs, you know it's a hardware/compatibility issue. You might want to take a snap shot of this screen and put it here so we can see exactly how the system is configured.

Bingo, you're the man!
He is - and a few points my way for getting you to show the config and landing him in the right spot would be appreciated since I couldn't answer back within the hour.
Is all the memory the same type (UDIMM, RDIMM, LRDIMM?) They can't be mixed.
Quad rank RDIMMs aren't supported.
LRDIMMS are capable of up to three DIMMs per channel.
And the list goes on.
Send over the specs of the memory (Even just part numbers if you want) and we'll see what we can do.
You can also review this document which explains some of the do's and don'ts.
