Hello, I recently purchased a new graphics card and have now decided to upgrade my computer's memory as well. My PC is a Gateway FX530XM with motherboard model OEMD975XBGG1. With the help of a computer scan by Crucial, I was able to determine that my current memory is DDR PC2-5300. If someone could tell me which types of memory are available to me at the present time, I would be very appreciative. Also, if any more information is needed, I will be glad to provide it.
