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 blue 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

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.2 No.5), or identical DDR3 DIMM pair in Dual Channel (DDR3_A1 and
DDR3_B1; Blue slots; see p.2 No.6), so that Dual Channel Memory Technology
can be activated. You may refer to the Dual Channel Memory Configuration Table
below.
