Windows 2003 Server - not using all memory

Posted on 2009-07-14
Last Modified: 2012-05-07
I have a HP ML150 G2 server with 2 CPUs.  I installed 2 2GB memory sticks and the BIOS and hardware recognizes the 4GB of memory.  When review the properties within MY Computer it only shows 2gb of memory.  I have added a line in the boot.ini file for /PAE and it does recognize the physical address extention.  

Why does it NOT recognize the memory?
Is my math bad and does each CPU take up 2 GB of memory?
Is there another view to show that windows is using all of the memory?

Have you tried updating the BIOS yet? The OS reads the BIOS for information on the memory installed.

At startup, I went into the BIOS, saw the BIOS recognized the amount of memory and "saved" the settings which displayed 4GB of memory.

I have NOT downloaded a BIOS and upgraded to a new version.  I am not sure if there is a new version.  Is this what you are refering to or what I have already done?

I understand that the BIOS is reporting it, but there could be some type of bug that is keeping the OS from seeing it. I would try a BIOS update to attempt to resolve this issue. Do you have the motherboard or computer model information?

Which edition of Windows Server 2003 are you using?

If you are using the Windows Server 2003 Web Edition, it will only support 2GB of RAM no matter how much is installed.
