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_A1 and DDRII_B1; Yellow slots; see p.11/12
No.5), identical DDR2 DIMM pair in Dual Channel B (DDRII_A2 and DDRII_B2;
Orange slots; see p.11/12 No.6), or identical DDR3 DIMM pair in Dual Channel C
(DDR3_A1 and DDR3_B1; Green slots; see p.11/12 No.7), so that Dual Channel
Memory Technology 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.

1. If you want to install two memory modules, for optimal compatibil-
ity and reliability, it is recommended to install them in the slots of
the same color. In other words, install them in the set of green
slots (DDR3_A1 and DDR3_B1), in the set of yellow slots
(DDRII_A1 and DDRII_B1), or in the set of orange slots (DDRII_A2
and DDRII_B2).
