Hi I just bought 1 more gig of RAM for my Computer. its an HP Pavilion a1340n. it has 2 Slots for RAM. Speccy and CPU-Z reads Both RAM sticks but when I right click "My Computer" it says Im only using 1gig. I run WIndows XP SP3 34-bit. I don't know much about computers just a bit. And i did switch the Cards around and used each card on it own and they all worked just they wont add up when both are in use.
your system has onboard gpu...set to use 256m of your system ram. the rest of the lost ram is from intel mb.
