Physical memory question

[Guest]

Newbie question here:

I'm running a P4 3.06 GHz with Windows XP Pro installed.

I have 1 GB of RAM installed.

When I look at the "System" item in Control Panel, it
shows 1 GB of RAM under the "General" tab.

When I look at "System Information" under Accessories,
however, it shows "Total Physical Memory" = 512 MB.

Is this normal? Shouldn't they be the same?

Just checked mine - I have 2.0Gb installed and both places you mentioned
show the full 2.0Gb. Go to www.crucial.com and run their memory test.
Download The Belarc Advisor www.belarc.com and see what it says.

You are running your memory in Dual Channel right? That has been known
to be read wrong. Check and see if there is a BIOS update available.
