I have PS CS3 and am running a Dell precision workstation 690 with 4GB ram, 1.6GHz Xeon duo core processor, NVIDIA Quadoro FX 3450 video card. I have a tiff that is 705.4 MB and when I try to open it an error message pops up and reads: could not compelte your request because there is not enought memory (RAM).

I have gone into preferences/performance and moved the memory usage up to 70%. Do I really need to purchase more RAM for the computer?

No, you can only access about 3 gigs anyway. If opening in Bridge look in preferences, they have a box that you can adjust to limit size of file opened. Don’t know if PS3 has same system.

How much empty space do you have on the drive(s) you are using for scratch files?

There is also a RAW cache file in Bridge that has a default limit of 1 gig. Some have increased this to 10 gig to solve some problems, although that may be overkill. Not really sure why Bridge has 2 caches, and it your tiff file would use it, just a thought.

700 megs is a huge file, never used anything close to that.

John,

Try closing all your other apps and see if that helps, or reboot and try it before opening anything else. Use Photoshop->File->Open instead of Bridge to eliminate that as a cause.

Also, as Michael suggested, you need *lots* of empty disk space for Photoshop to open a file that large. I work with images that size a few time a year and have never had an issue, even when I had an old P4 with 2G RAM a couple of years ago. So your system should be up to the task. I’ve even worked (slowly) on 2GB images on the old P4 so your 4GB RAM is not the culprit. But I’ve always used an empty 2nd hard disk (my fastest drive) for Photoshop to use for its scratch disk.

Okay I will install a second drive as the scratch disk. Any recommendations on the GB size of the drive?

Raptor 74gb or 150gb scratch disk will do fine….or a fast 7200rpm – I have found my Seagate’s 500gb to be quite fast too but I only use those for image storage and back-up

I too ran into this error, CS3 10.0.1, XP, 2.5 GB RAM, 10 GB virtual memory, plenty of scratch disk. The file size plays no role, only the image size (in pixels) and the bit depth are relevant.

If the image happens to be in 16bit and you can change that (obviously not in Photoshop), give it a try with 8bit. I got the error with a TIFF image of 170 Mpix in 16-bit, but it works in 8-bit, even with multiple layers.

Are you opening the file straight to PS, or through ACR (camera raw)? What program generated the file?

"Not enough memory"-messages are almost always scratch disk related. It may be big enough, but fragmented.

A separate, dedicated drive for scratch is the only way to go.

No, a separate, dedicated scratch drive is not the "only" way to go. If your scratch files are on a fast, buffered drive with sufficient space that is defragmented reasonably often, you are good to go.

I agree, however, that messages claiming there is not enough memory often point to insufficient usable scratch file space. Such messages can also mean that you have too much memory devoted to Photoshop, rather than too little. If you run into these messages and your memory allocation to Photoshop is over 55-70% try reducing to 55% and see if you can complete the operation that previously failed.
