Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one memory module is installed.
2. When enabling Dual Channel mode with two or four memory modules, it is recommended that memory
of the same capacity, brand, speed, and chips be used and installed in the same colored sockets. For
optimum performance, when enabling Dual Channel mode with two memory modules, we recommend
that you install them in the DDR3_1 and DDR3_2 sockets.
