Ok I have a Compaq HP laptop that was in real bad shape so I took out the RAM stick from it. I want to install it into my Sony Vaio Desktop computer. What information do I need to get to check if the memory is compatible. The RAM stick from the laptop is a Hynix brand and here is everything it says on the sticker:
PC2700S-25330_____0448
256MB DDR 333MHz CL2.5
HYMD232M646D6-J AA
Physical size is different. A laptop ram stick is about 2 and a half inches long, and your Sony Vaio desktop probably uses DDR2 ram which is 5 and a half inches long. DDR2 Sdram has 240 pins on the bottom. Your laptop ram has 200 pins (DDR SODIMM)
1.DDR Sdram: (Even if your desktop's ram is DDR, it has 184 pins,(Contacts), and is 5-1/2" long.
