Low memory/System Resources Warning

One of our engineers is having a problem with Solidworks where he is getting a low memory/system resources warning.

His system specs are as follows:

SW 2011 64-bit SP 5.0

Windows 7 Pro 64-bit

Core i7-2600K CPU (not overclocked)

16GB Ram

ATI FirePro V4800

The thing is there is just no way he is using up all 16GB of RAM and the task manager confirms this. There are two other engineers with identical computers that don't have this problem. Any ideas? Thank you.
