Windows 2003 Physical address Extension does no match more than 3GB

[sonnet]

Hi ,

I have a problem on a machine where I have installed 4GB .

If I select "System properties", the system only "see" 2.93 GB,

it appears something like this:

Computer:

Intel ®Core 2 CPU

6300 @ 1.86 GHZ

2.93 GB of RAM

Physical Address Extension

Even from task manager is the same.

But as you see on system properties Physical Address Extension seems to be activated.

The OS is Windows Server 2003 Enterprise, with service pack 2 installed.

Dopes anyone knwos what the problem is?

If i launch from start-run msinfo32.exe it returns an error message (windows server is nlited,so it could be something related to it)

I read the link

You really need to see what msinfo32 reports, as it's probably going to be close to 4GB of RAM. If that ends up being the case, you may have to disable features in the BIOS or remove some of your add-in cards to get some of that RAM back.

Run a 64 bit OS, and the issue will be fixed. Otherwise, yes, removing video cards and other add-in cards can increase the RAM you can use.

Building an nLited server? Really? (/surprise) -- for test use only, right?
