    I have two laptops - an acer 5670 and an EiSystems 4430. The EiSYstems is about four or five years old and only has 256MB of RAM which I want to uprate. I bought a 200 pin 1GB PC2-4300 SODIMM DDR2 card from PC World but this did not fit the EiSystems machine. The only PC2100 available seem very expensive. Can anyone tell me why a 200 pin will not fit. What is the significance of the PC2100, PC4300 etc? :rolleyes:

    The PCXXXX relates to which chip set the memory can be used with, if your chip set does not match the memory then it will not work.

    You need to buy DDR RAM. You bought DDR2 RAM. DDR2 RAM will not work in a system that uses DDR RAM.

    your laptop uses DDR SO-DIMM RAM. The one you bought is DDR2, which is newer and non-compatible.

    DDR memory is expensive because it's not widely used now and in low stock.
