I just bought an Optiplex 7010 from Dell Outlet, and have a question.  The technical guidebook to the 7010 says that each of the four DIMM slots can handle up to 8GB memory modules, but then says the system maximum is only 16GB.  I know you must have Windows 7 Professional or Ultimate to access more than 16GB. Provided you have that, can this motherboard handle over 16GB?  If I added two 8GB sticks to the 2X4GB already installed, would it work, or would the machine not function or only recognize 16GB of it?
