First of all, uninstall SiSoft Sandra. This step helps a lot

Secondly, move the module in Slot 2 over to Slot 3 to enable your dual-channel memory setup, as per your motherboard owners' manual. Slots 1 & 3, and 2 & 4, are "paired." You can add a second pair of modules in slots 2 & 4 later if you want; they need to match eachother in logical organization, but they won't need to match the first pair.
