2.3 Installation of Memory Modules (DIMM) This motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM slots, and supports Dual Channel Memory Technology. For dual channel con- guration, you always need to install identical (the same brand, speed, size and chip-type) DDR3 DIMM pair in the slots of the same color. In other words, you have to install identical DDR3 DIMM pair in Dual Channel A (DDR3_ A1 and DDR3_B1; Blue slots; see p.12 No.7) or identical DDR3 DIMM pair in Dual Channel B (DDR3_A2 and DDR3_B2; White slots; see p.12 No.8), so that Dual Channel Memory Technology can be activated. This motherboard also allows you to install four DDR3 DIMMs for dual channel con guration, and please install identical DDR3 DIMMs in all four slots. You may refer to the Dual Channel Memory Con guration Table below. Dual Channel Memory Configurations DDR3_A1 DDR3_A2 DDR3_B1 DDR3_B2 (Blue Slot) (White Slot) (Blue Slot) (White Slot) (1) Populated - Populated - (2) - Populated - Populated (3)* Populated Populated Populated Populated * For the con guration (3), please install identical DDR3 DIMMs in all four slots. 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 either in the set of blue slots (DDR3_A1 and DDR3_B1), or in the set of white slots (DDR3_ A2 and DDR3_B2). 2. If only one memory module or three memory modules are installed in the DDR3 DIMM slots on this motherboard, it is unable to activate the Dual Channel Memory Technology. 3. If a pair of memory modules is NOT installed in the same Dual Channel, for example, installing a pair of memory modules in DDR3_A1 and DDR3_A2, it is unable to activate the Dual Channel Memory Technology . 4. It is not allowed to install a DDR or DDR2 memory module into DDR3 slot; otherwise, this motherboard and DIMM may be damaged. 5. If you adopt DDR3 2400/1866/1600 memory modules on this motherboard, it is recommended to install them on DDR3_A2 and DDR3_B2 slots. 17

2.3
Installation of Memory Modules (DIMM)
This motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM
slots, and supports Dual Channel Memory Technology. For dual channel con-
guration, you always need to install
identical
(the same brand, speed, size
and chip-type) DDR3 DIMM pair in the slots of the same color. In other words,
you have to install
identical
DDR3 DIMM pair in
Dual Channel A
(DDR3_
A1 and DDR3_B1; Blue slots; see p.12 No.7) or
identical
DDR3 DIMM pair in
Dual Channel B
(DDR3_A2 and DDR3_B2; White slots; see p.12 No.8), so
that Dual Channel Memory Technology can be activated. This motherboard
also allows you to install four DDR3 DIMMs for dual channel con guration, and
please install
identical
DDR3 DIMMs in all four slots. You may refer to the Dual
Channel Memory Con guration 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 either in the set of blue
slots (DDR3_A1 and DDR3_B1), or in the set of white slots (DDR3_
A2 and DDR3_B2).
2.
If only one memory module or three memory modules are installed
in the DDR3 DIMM slots on this motherboard, it is unable to activate
the Dual Channel Memory Technology.
3.
If a pair of memory modules is NOT installed in the same Dual
Channel, for example, installing a pair of memory modules in
DDR3_A1 and DDR3_A2, it is unable to activate the Dual Channel
Memory Technology .
4.
It is not allowed to install a DDR or DDR2 memory module into
DDR3 slot; otherwise, this motherboard and DIMM may be dam-
aged.
5.
If you adopt DDR3 2400/1866/1600 memory modules on this
motherboard, it is recommended to install them on DDR3_A2 and
DDR3_B2 slots.
