Hi, I was runing OS X 10.0.4 on my iMac DV SE 400 with 128mb ram. Most of my carbon apps would take a long time to open (Eg. IE 5.1 23 bounces!). I recently splurged and got a 512mb ram upgrade. I put the ram in (and made sure it recognized it). I defraged my drive with System works and I optimized the drive (prebinding) with a Unix command. My Mac still runs just as slow in OS X. I know 10.1 will be out in September but I've read other people success stories stating faster speeds with more ram. Any ideas? Any suggestions? (other than "Get a G4") Thank you in advance.
