If it's not in the hardware documentation that came with it or under your servicetag at www.dell.com go to www.crucial.com and see what its memory finder thinks. It will tell you also what kind of RAM you need.

Okay I want to instal windows 7 on my dell vostro 1500 which is currently a 32 bit xp.
I read a 32 bit windows 7 can accept 4 gigs ram which is what I will need on this pc since it runs slow with windows 7.
So what I need to know is if the motherboard in this computer will support more then 2 gigs of ram.
Thanks
