Hi everyone, I'm looking to upgrade my iMac G5's (2.0 GHz 20in) stock 512 MB RAM to 1.5 Gigs. Crucial has a 1 GB stick for $139, while datamem.com has a stick for $105. OWC has theris for $117. Has anyone bought memory from datamem? They are listed in the guide on mac rumors, but I want to make sure that a) the RAM will work in my iMac, b) the RAM won't cause any issues on my mac, and c) datamem has good support and won't give me any problems if the RAM is DOA. Thanks!
