    Hey there, i'm having issues with the amount of RAM that Photoshop CS is using.

    I am using a PowerBook G4/12"/1Ghz with 768mb (256 + 512) of RAM, and yet a clean boot of OS X, running only photoshop and two B&W 500x500/72dpi sketches soon causes me to have no free RAM whatsoever. Photoshop is using 250-350mb of RAM, just to do that. Where the other RAM goes, god knows. If i total all the 'Real Memory' column up, I get around 450mb of RAM total in use.

    VM: 5.82G + 82.2M 506946(0) pageins, 512087(0) pageouts

    just about sums it up. My system has been up around 24 hours, and I have around 3.5gb of swap files on my disk in /var/vm.

    This can't be right, can it?

    Anyone got any ideas?

    Yeah, its right. Its OSX memory management.
    Osx loads as much as possible to memory and swaps it to disk when its not needed. It looks often bad, but it works great! Dont worry!!!

    I'm running terminal, Mozilla and iTunes now:
    (powerbook 12" 1.33 GHZ/768MB)
    PhysMem: 97.4M wired, 241M active, 209M inactive, 547M used, 220M free
    VM: 6.21G + 87.0M 154058(0) pageins, 82954(0) pageouts

    Nothing to worry about, you wont run out of memory in osx, it's only getting a bit slower when you are running out of real free memory..

    a related RAM question. I have a new 2.5Ghz G5, and I am starting to learn Final Cut Express2. Does anyone know the optimal RAM amount?

    [In certain apps, more RAM won't help. Ex: MS Word won't run better with 3GB of RAM versus 1GB.]

    More is always better.
    Depends on how long videos you are working on.
    I've edited several hour long videos in Premiere (first version 5 in os9 and later 6.5 in osx) for several years with a old G4/400 with 512 MB ram (which was MUCH four years ago) without problems.
    (i've also edited videos on a G3/266 with 128MB in Strata VideoShop 6 years ago...)
    For a hobbyuser 1GB would be more than enuff.
    I'm editing on a PB 1.33GHZ with 768MB and its great.
    One of my best friends are studying for a master in animation, and he uses a powerbook 1.0 ghz with 768 mb ram and he thinks that its great too :)

    If you are just using your computer for 'every-day' tasks like web, e-mail, word processing, you aren't going to notice much (if any) speed boost after 1 GB. If you are doing video editing, bump that up to 2-3 GB. If you plan on running Final Cut, Photoshop, Motion, DVD Studio Pro, and Flash all at the same time, you may want to go ahead and get a full 8 GB.
