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 A (DDR3_A1 and DDR3_B1;
Blue slots; see p.2 No.5) or identical DDR3 DIMM pair in Dual Channel B
(DDR3_A2 and DDR3_B2; 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 iden-
tical DDR3 DIMMs in all four slots. You may refer to the Dual Channel Memory
Configuration Table below.

For the configuration (3), please install identical DDR3 DIMMs in all four
slots.
1.
If you want to install two memory modules, for optimal compatibility
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 blue slots
(DDR3_A1 and DDR3_B1), or in the set of white slots (DDR3_A2
and DDR3_B2).
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.
If a pair of memory modules is NOT installed in the same Dual
Channel, for example, installing a pair of memory modules in
DDR3_A1 and DDR3_A2, it is unable to activate the Dual Channel
Memory Technology .
4.
It is not allowed to install a DDR or DDR2 memory module into
DDR3 slot; otherwise, this motherboard and DIMM may be damaged.
5.
If you adopt DDR3 1800/1600 memory modules on this motherboard,
it is recommended to install them on DDR3_A2 and DDR3_B2 slots.
