I have to get the detailed info later, its laptop ram a 512MB module, it was just removed from a laptop a friend purchases so he could upgrade to 2GB, it only has maybe 5hours use on it. It came out of a new Dell Laptop so it should be pretty current with some of the newest ram out. Im not asking much since it is so light shipping wont really cost anything... 25$ shipped (wont ship outside usa). If your intrested aim - d92stealth or email johnfiac at hotmail.com to get specs faster. Otherwise ill post them on here later on.
