A friend of mine has a Sony vaio PCG-FRV23 laptop with a broken screen.:dead: He wanted to throw it away but i asked for it thinking i could use some of its parts. I want to take the ram from it and add it to my cpu. Since the screen is broke i had to find its info from sony and found out it has a 512 MB DDR SDRAM (256MB x 2). I want to add it to another cpu, a Hp Pavilion DV 5000 that currently has 512mb of ram and has 2 slots with a maximum capability of 1 gb each. so would that mean i could only add 256 mb onto my Hp, and would it be compatible with my cpu? From what I read on google the MHz of each ram has to be identical but how do I know the speed of the Sony? MY Hp is measured in GHz and has 1.79GHz.
