I have a Compaq Presario CQ50 and a Compaq 510. Both of which are 2GB when shipped. Now, I've bought 4 GB of Kingston Ram and upgraded both of my laptops to 4 GB. However it is only reading 2.91 on both. The 510 is running XP while the CQ50 is on Windows 7. I understand that it reads 3 to 3.5GB only, but it would be great if I can read them. Help.

On some computers, a 32 bit system will not utilize over a certain amount (approx. 3.2GB...). A 64 bit system does not have this limitation.
Also, you will need to consider how much RAM is set aside for any onboard graphics.

With out upgrading the OSs to 64bit (Vista or 7) you are wasting money. If you were running a 64bit OS you would be seeing ~3.6GB reported to OS & the remainder being used for video memory.
