Brian, Most of the DDR I have is 512MB, and I'm trying to get my "server" up to 4GB instead of 2 (it's an AMD opteron Sun x2100). I will check geeks.com as well as NewEgg. I'll also call Tatooine, I'd never heard of them before. Getting to Cheyenne isn't a problem, until recently I worked up there. Thanks for the info! Rob
