I just completed assembling a new rig. The mobo can take up to 32 Gig RAM. But when I installed Win 7 Home Edition 64 bit it warned me that it can only take 16G max RAM. This was verified by a PC repair shop. I was told that my option was to go with the Win7 Ultimate if I were to take advantage of 32 G RAM the mobo can support. I knew about the limitation concerning the Win7 HomEd 32 bit but I thought the 64 bit can handle it. Any thoughts in this matter?
