Hi all, I have a G4 upgraded Mac 9500 running DP 2.7 (peripherals include ATTO SCSI II Card, 2408 mkII, 10k external hard disc, etc.) with 288 megs of ram. I have read that putting in more ram takes strain off CPU. Just how much is enough? In my case, I try to conserve my CPU power as much as possible. For example: Not using reverb plug-ins real time Letting my ATTO card work as much as possible. I never get close to using all my ram (according to configure studio set up in DP 2.72) while getting 30+ tracks with some plug-ins. Usually my CPU gets overloaded before I get anywhere near using all my memory. Have I been misinformed? Should I put more ram into my computer? I guess I really need to learn the proper interaction amongst processor, memory, system bus, etc. in the mac platform. This question is due to my lack of such understanding. Thanks for your input.
