This motherboard provides four 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_3; Yellow slots; see p.11 No.6),
identical

 DDR2 DIMM pair in Dual Channel B (DDRII_2 and DDRII_4; Orange

slots; see p.11 No.7), or identical DDR3 DIMM pair in Dual Channel C (DDR3_A1
and DDR3_B1; Green slots; see p.11 No.8), so that Dual Channel Memory Technol-
ogy can be activated. This motherboard also allows you to install four DDR2 DIMMs
for dual channel configuration, and please install identical DDR2 DIMMs in all four
slots. You may refer to the Dual Channel Memory Configuration Table below.
