Did your PC boot and count 2 gig of RAM at start up? (You may not be able to see this if the splash screen is enabled in your BIOS)
But you can look here for certain and tell:
Under Control Panel, System Tab, then Computer, does it say 2GB of memory?
If it does, then you are just fine.
thanks for reply
