This motherboard provides two 240-pin DDR2 (Double Data Rate 2) DIMM slots and
two 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) DDR2/DDR3 DIMM pair in
the slots of the same color. In other words, you have to install identical DDR2
DIMM pair in Dual Channel A (DDRII_1 and DDRII_2; Yellow slots; see p.12 No.
4) or identical DDR3 DIMM pair in Dual Channel B (DDR3_A1 and DDR3_B1;
Green slots; see p.12 No.5), so that Dual Channel Memory Technology can be
activated. You may refer to the Dual Channel Memory Configuration Table below.

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 in the set of yellow slots
(DDRII_1 and DDRII_2), or in the set of green slots
(DDR3_A1 and DDR3_B1).
2. If you install only one memory module or two non-identical memory
modules, it is unable to activate the Dual Channel Memory Technology.
3. It is not allowed to install a DDR3 memory module into DDR2 slot or
install a DDR2 memory module into DDR3 slot; otherwise, this
motherboard and DIMM may be damaged.
4. DDR2 and DDR3 memory modules cannot be installed on this
motherboard at the same time.
