Thank you, this is very useful scanner!

This is what it showed:

Memory Type: DDR PC2700, DDR PC3200, DDR (non-ECC) Maximum Memory: 4GB Currently Installed Memory: 512MB Total Memory Slots: 4 Available Memory Slots: 2

In this situation, will it be good and affect the performance if I buy 4x512 MB of DDR and install them in 4 slots? Of course after getting out the 2x256 I currently have?
