I currently have Windows 7 Home Premium 32-bit and people here keeps telling me I should move up to 64-bit so I decided to upgrade my RAM and move up to 64-bit. The ones I currently have on my system is a Corsair Dominator DDR2 4GB (2X2GB) v1.1 kit So I bought another dual kit set but with version 2.2? Is there going to be any issues or problems with that? I have my complete system component list on left side. Thanks! Update: problem solved.
