2.3 Installation of Memory Modules (DIMM)
This motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM slots,
and supports Dual Channel Memory Technology. For dual channel configuration,
you always need to install identical (the same brand, speed, size and chip-
type) DDR3 DIMM pair in the slots of the same color. In other words, you have to
install identical DDR3 DIMM pair in Dual Channel (DDR3_A1 and DDR3_B1;
white slots; see p.2 No.6), so that Dual Channel Memory Technology can be
activated. This motherboard also allows you to install four DDR3 DIMMs for dual
channel configuration, and please install identical DDR3 DIMMs in all four slots.
You may refer to the Dual Channel Memory Configuration Table below.

and reliability, it is recommended to install them in the slots of the
same color. In other words, install them either in the set of white slots
(DDR3_A1 and DDR3_B1).
2. If only one memory module or three memory modules are installed
in the DDR3 DIMM slots on this motherboard, it is unable to activate
the Dual Channel Memory Technology.
3. It is not allowed to install a DDR or DDR2 memory module into
DDR3 slot;otherwise, this motherboard and DIMM may be damaged.
4. Please install the memory module into the white slot (DDR3_B1) for
the first priority.
