Doesn't matter if you're using a large percentage of your memory or not, it can read from/write to both channels at the same time instead of just 1, greatly increasing system responsiveness.
hmmmm. I need to ask....... Are you sure?

1. Dual Channel mode cannot be enabled if only one DDR3 memory module is installed.

When enabling Dual Channel mode with two memory modules, be sure to install them in the DDR3_1 and DDR3_4 sockets. When enabling Dual Channel mode with six memory modules, make sure that memory modules to be installed on the DDR3_3, DDR3_2, DDR3_6, DDR3_5 sockets are all single-sided.
