Windows Server 2008 R2 Memory Usage Problem

[nilmanna]

Hi,
I have IBM X3650 M3 server, OS is Windows 2008 R2 Ent. 64bit.
I have installed 12GB RAM. Post screen can detect 12GB RAM but in OS it's showing as " Physical memory 12GB (8 GB usable).
What could be the reason?
How to make 12GB usable in Windows 2008 R2 Ent?
Please suggest.

Sorry BSchwarz, I don't want to "bypass" you but I had a similar problem...

There're only 2 solutions:

Download the latest firmware for you motherboard (PAY ATTENTION - IBM'S SERVERS NEED A SPECIFIC PROCEDURE TO UPDATE FIRMWARES, SOMETIMES YOU NEED TO UPDATE THE CONTROLLER FIRST AND THEN YOUR MOBO!)

The other "solution" is to replace the ram... it could be faulty.

Cheers
