Hey, i'm using a 17" PB and i am using photoshop 7 with several 30-60meg files open at once. This really makes my system lag. I thought that i could change photoshop so it used less minimum and preferred memory. So i get the info on it, and try changing it through the 'memory' tab. But it wont let me change the numbers.

How do i change them? I was hoping to set the minimum at about 30meg and the preferred at 128, so photoshop has more free ram to play with.

I've looked in the photoshop preferences already, and the memory settings in there are not what i'm looking to customise, so please don't advise me to do that.

Thanks in advance.

I'm assuming that you are running photoshop in OS X, since you are posting in the OS X forum. If so, those numbers you are looking at are irrelevant. That's just the classic memory preferences. OS X gives memory to programs dynamically. You don't have to worry about that stuff in X.

The recommendation is then to buy more RAM or quit other applications.

Wrong.

Photoshop for OS X has a preference which sets how much memory PS grabs. It's under Preferences/Memory & Image Cache, and it controls the maximum amount of RAM Photoshop will use. I have a gig of RAM and have it set to 35%, which works out to 319 MB. To calculate the amount of RAM you need, take three times to size of the largest file you will work on and multiply that amount by three.

Remember if you give Photoshop tons of RAM other apps will have little to use and VM will come into play and slow things down that way also. So be careful.
