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 (DDRII_1 and DDRII_2; Yellow slots; see p.11 No.3), or
identical DDR3 DIMM pair in Dual Channel (DDR3_A1 and DDR3_B1; Black slots;
see p.11 No.4), 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 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 black slots
(DDR3_A1 and DDR3_B1), or in the set of yellow slots (DDRII_1
and DDRII_2).
2. If only one memory module is installed in the DIMM slot on this
motherboard, 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.
5. DDR3 memory module is only supported by installing AM3/AM3+
CPU. DDR2 memory module is only supported by installing AM2/
AM2+/AM3 CPU.
