Photoshop CS2 Doesn't See My New RAM??

[Scott Rosenberg]

hey fellas, i was under the impression that CS2 could use up to 4 gigs of RAM. well, i just upped my memory from 2 gigs to 4, but in CS2 when i goto:

edit-> preferences-> memory and image cache

the program still shows 1760mb as my available ram. under system info in windows, i see 3.37gb of RAM, but not in photoshop. my bios shows a full 4gigs, oddly enough.

is there something i need to do to get CS2 to 'see' the extra memory? i've read about the 3gig switch in the boot.ini, but have also heard that can cause lots of problems. since my bios and os is seeing more than CS2, i figured there might be some setting in the program that i need to play with.

i'm running XP Pro Service Pack 2 if that makes a difference.

thanks,
scott
