I want ot upgrade my memory to 4 GIG. Currently my two slots are occupied by two 1 Gig modules giving me 2 GIGs of RAM. I just read that 2 GIG is the max for my system. Is this correct? Is this just a "recommendation" or a system limitation? Has anyone out there heard of anyone trying 4 GIG upgrade?

I run Auto CAD 2009 and mutiple windows/software programs continuously.

Thanks
