Windows Server 2008 R2 Standard - Usable RAM is 50% of installed RAM
Hi Experts,
We have a box running Windows Server 2008 R2 Standard.
We recently replaced the RAM with 4 sticks, each of 2 GB (the same 4 sticks worked OK in another PC).
Now Windows Computer Properties reports:
Is there something we need to do to make all the RAM usable?
Regards,
Leigh

Installed memory (RAM): 8.00 GB (3.99 GB usable)
Is there something we need to do to make all the RAM usable?

Also, is this a Dell? I know I've seen some BIOS options on a few Dell servers that will allocate ram as "Spare" instead of normal or "optimized". Have you checked your BIOS for any weird ram options?

Hi Guys,
I decided to buy 16 GB (4 x 4GB) to replace the 50% functioning 8 GB.
We couldn't afford to have any server downtime if we attempted to move the 4 x 2 GB sticks.

It looks like you have 32 bits system - it is maximum it will support - to support more then 4GB you will need 64 bits R2 system
