Memory allocation

I''m running SolidWorks on a Dell Precision M6700 laptop.  When the laptop was purchased it came with 8 gig of RAM memory.  After running the computer for a while I had our IT department add some RAM memory and I'm currently running 20 gig.  I'm concerned that SW is not utilizing the new RAM.  Is there a way to get SW to recognize and use the additional RAM?
