Hmm.. apple screwed up my order at first. they sent me my 17" 1.5powerbook with only 512mb of ram when i ordered it with 1 slot for a 1gb stick of ram. they told me they would send me the gb stick and let me keep the 512. So for about 2 weeks i used my powerbook with 512mb of ram. I played around with photoshop, and final cut pro with it and everything seemed to run ok. My xbench scores came out to 132.97. Just today they sent me the gb stick so i installed it and now i have 1.5gigs of ram. It shows up under the 'about this mac' menu so i know its there. The problem is, so far i havent noticed any differences at all. After effects, final cut pro, and photoshop all run at the same speed. X-bench even scores a tiny bit slower. its at 132.49 right now. the memory test scored a tiny bit lower by 3. (ram = memory?) Both times i ran the test were right after i turned the computer on so nothing else was running. ummm...... I also have menu meters runing and it showes only 168mb's of memory being used. The most i could get it up to was 400 by opening over 100 google windows, photoshop, illustrator, after effects, final cut pro, i tunes, word, quicktime and aim (i did it to test the memory.) it doesnt even go about 300mb's when doing a ram preview of the famous nightflght with after effects. Im trying to figure out how everybody is saying that there computer is so much faster after installing new ram. I havent started any projects from scratch yet with the new ram on these programs... would that take more? Shouldnt the computer be using a larger percentage of the ram to make things run even quicker? Im so confused :-/ can somebody please guide me to the right answer?
