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 confi guration,
you always need to install identical (the same brand, speed, size and chip-type)
DDR3 DIMM pair in the slots. In other words, you have to install identical DDR3
DIMM pair in Dual Channel (DDR3_A1 and DDR3_B1; Black slots; see p.12 No.6)
or identical DDR3 DIMM pair in Dual Channel (DDR3_A2 and DDR3_B2; Black
slots; see p.12 No.7), so that Dual Channel Memory Technology can be activated.
This motherboard also allows you to install four DDR3 DIMMs for dual channel
confi guration, and please install identical DDR3 DIMMs in all four slots. You may
refer to the Dual Channel Memory Confi guration Table below.

For the confi guration (3), please install identical DDR3 DIMMs in all four
slots.
1. Please install the memory module into the slots DDR3_A2 and
DDR3_B2 for the fi rst priority.
2. If you want to install two memory modules, for optimal compatibility
and reliability, it is recommended to install them either in the set of
slots DDR3_A1 and DDR3_B1, or in the set of slots DDR3_A2 and
DDR3_B2.
3. 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.
4. 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 .
5. It is not allowed to install a DDR or DDR2 memory module into
DDR3 slot; otherwise, this motherboard and DIMM may be dam-
aged.
6. If you adopt DDR3 1866/1600 memory modules on this mother-
board, it is recommended to install them on DDR3_A2 and DDR3_
B2 slots.
