Will this RAM work on my Dimension E521: Samsung 1GB 2Rx8 PC2 5300U-555-12-E3
I'm about to do an upgrade for this computer and would like to know what model number of Crucial 800 MHz memory will work with it if I can't use the RAM mentioned above..  I was told by somebody on the crucial forum for the Ballistix memory will not work on the Dimension E521 but I've seen people on this forum that are using Ballistix RAM.  For you who are using this memory are you having to change any settings manually, or does the computer recognize it on its own.
