4 gb of ram displays as 3.5 gb in system properties

[Guest mhowell]

I have 4 gb of ram installed in a Windows 2003 Enterprise server but only 3.5

gb displays in system properties. What do I need to do to utilize all 4 gb

of ram.

Alternatively use Google since this is a FAQ

I usually do. However, I have blogs blocked at work and can't review them.

Hi,

I had the same problem. Simply add /PAE (= physical adress extension) to

your boot.ini and reboot your system. The system properties should now change

to 4 GB usable RAM. It has something to do with shared memory from some cards

in your system that use memory the system then cannot allocate (if I have it

correct in my memory).

 

Greetings
