Hi

Does anybody know which 1Gb SODIMM memory modules that will work on this c640 laptop. I know that "officially" it can only take 512 Mb but I also know that many people has got it to work with 1Gb modules.
So can anyone give examples of which modules that will work / not work....Thanx !!

Go to crucial.com. They have a section that tells you what RAM will work with your computer. Otherwise I don't know.

the problem is that all crucial, kingston memory configurators uses the "official" 512 Mb only as option.
one of my memory slots is broken so I have to use the other one, which means that I need a 1Gb memory module to upgrade from the 512 Mb I have now.

I have this exact Laptop and It holds a maximum of 1GB of memory. It has 2 memory banks. So the largest single sodimm you can put in it is 512mb. If one of your memory banks is broken then the max memory you can install is 512mb. Sorry.

Have you actually tried to put a 1gb module in? I have the same problem as mrjack10 and would like to find a 1gb module that works.

Memory is cheap so it's worth to try.
I had one C640 long-long time ago and it worked with 1GB DDR SO-DIMM modules just fine.
