Only 32GB of 128GB of memory useable?

We have a small business 2011 server from dell that has 128Gb of memory that came preinstalled from them.

Upon booting up the machine and going through the initial settings and getting everything up and going we noticed it only has 32Gb of 128Gb of memory that's usable.

I've seen small differences in the past when a computer has a video card taking part of the memory on a x86 machine, but why would this be happening, (and with such a large number) on this x64 server box?

What can I do to utilize the rest of the 96Gb of memory?

Windows Server 2008 R2 Standard is only licensed for 32GB of RAM.

If you have a Windows Server 2008 R2 license either standalone or via Premium Add-On you could install Hyper-V and run VMs on that machine.

This from HP:
System Requirements:
o Processor: Minimum Quad core 2 GHz 64-bit (x64) or faster for 1 socket (due to Exchange Requirement)
o Memory: Minimum: 8 GB / Recommended: 10 GB* / Maximum: 32 GB
o Hard Drive: 80GB or larger
As they said above MAX memory 32GB.  I would contact Dell since I just purchased it and ask why they sold you so much memory.

It's a dell poweredge r715. Shoot thats crazy it's limited at 32. Even windows 7 pro offers way more.

Hello,

This is due to SBS 2011 Standard having its max memory capped at 32GB.

I suggest you get refunded for the additional RAM.

Or you could install ESXi 5.5 and use that RAM several servers, including your SBS 2011.
surprised they did not sell you SBS 2012.

There isn't an SBS 2012.  It was discontinued with 2011.  There is Server 2012 Essentials but it isn't like for like.  I.e. there is no exchange component and has a limit of 25 users etc.

Installing ESXi is an option but even then your SBS 2011 VM will only have 32GB of RAM.

You can hardly blame Dell for selling you all that RAM, for all they knew even if you bought SBS with it you were going to use something like VMware and have other virtual machines running in the extra RAM.

You have one more CPU than is useful for a small business too, actually more like 6 times as much CPU as you need but you can't slice them in half of course. Requirement posted up by pjam is 4 cores, and you've got 24 of them if it really has a pair of Magny-Cours in it.

Dell should have informed you about the 32gb cap of SBS.  It is what they do, sell computers with Windows OS.   Could have been an easy upgrade for him to sell you 2012.  You can install 2012 standard and run 3 virtual machines under it or get datacenter and run as many as you want under it.
