I am running Windows XP Pro and recently upgraded RAM from 2GB to 3GB. Windows System Information reports Total Physical Memory of 3,072 MB. However, Photoshop CS (as well as Photoshop 7) report Built-in memory and Free memory as 2,048 MB, and Memory available to Photoshop of 1,778 MB. Any thoughts on this discrepancy?

Free memory as 2,048 MB, and Memory available to Photoshop of 1,778 MB. Any thoughts on this discrepancy?

There are number of threads that have discussed this in recent weeks, so a search of the (edit) forum should turn up fairly detailed explanations. If you don’t want to search then the following quick and dirty explanation should help:

1. Photoshop can only address 2GB of ram.

2. The available ram is a "questimate" based on 2GB minus an allotment for the OS and some PS plugins, filter, etc that run outside the available ram.

3. If you set the Photoshop memory slider to 100% then Photoshop will use all of the "real" amount of available ram up to a limit of 2GB.

Just to note that every application can only address 2GB of RAM (it’s not some goofy limit we put in, but a fundamental computer science issue).

Setting the Photoshop memory slider to 100% may prevent some sub-opimally written plug-ins from working (which, unfortunately, includes some of the included filters). If you don’t see problems, don’t worry about it. Just something to keep in mind.

So, we do realize that "bumping" a thread in this way does nothing to make it more visible to many people (who use a newsreader, like me)? Ok, just checking.

I do scott. It’s just that many of your posts (imo very important and informative) wind up on page 2 or 3 of the web view as soon as you post them (delay in NR server posting i guess?) so the people you’re responding to and others who may never look past the 1st page never get the advantage of sharing your wisdom. <g>

For example, the line about setting the mem slider to 100% and what happens is pretty important, not only to the original questioner, but to the community over all.
