A while ago I upgraded the ram in my 24" iMac from 1GB (2 512mb sticks) to 2GB. The 512mb sticks have been laying around and I'm wondering if they can be used in an older Dell Latitude D800 notebook I have? That computer currently only has the 512mb of ram it came with, and I would love to upgrade it. It's got a 1.8ghz Pentium M processor. The overall specs I believe are here (damn thing weighs more than a 17" MBP). The Ram from the iMac is a Hynix 2Rx16 PC2-5300S 512mb. Sorry I'm not too familiar with Ram, so any help would be appreciated!
