System Properties shows false RAM size?

[churin]

I recently added 2GB RAM making the total size to be 4GB but the System
Properties shows only 2GB. On the other hand System Information of
System Tools shows 4GB. How can I check to see if 4GB is being actually
utilized or not? The OS is WXP Pro with SP3 installed.

No, there is no check mark on "MAXMEM".
Thanks for your response anyway.
