Under options, Under the AI tab, you can disable the "give AI more time" and under system tab you can check the "allow high memory" box.
Another thing to ask you is how many applications do you have running in the background?
Sometimes running too many applications can "eat up" your free memory.
Things like anti-virus and msn/yahoo/aol programs will hog chunks of it as well.
A quick way to tell how many applications are running is to check your lower right hand tool bar, if you have 6 or 8 or more icons showing you may want to turn them off. You can turn off anti-virus and disable your internet connection while gaming to free up more RAM without risking folks trying to access your PC or other illegal measures.
To find out how much free RAM you have using windows XP, Ctrl+alt+del and go to your performance tab. On the right you will see a box listing Physical Memory(K).
Your total and available will clearly be shown there.
By installing 2 GB of system RAM, you pretty much can gurantee plenty of available RAM when gaming, regardless of how many other applications you are using. Having a dual -core processor helps by allowing you to multi-task.
For example, I have a high end Intel Core 2 Duo system with 2 GB of RAM and I can easily virus-scan, defrag my hard drives, burn a DVD and play just about any game on the market all at the same time.
Sure it's pretty silly to have to do all that, but it's problems like the ones you may be having that I won't ever have to worry about.
Good luck and if you have any more questions, I'd be more than glad to help.
I am a computer enthusiast and enjoy trouble-shooting hardware issues.
