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 configuration, you always need to install identical (the same
brand, speed, size and chip-type) DDR3 DIMM pairs. In other words,
you have to install identical DDR3 DIMM pairs in Dual Channel A
(DDR3_A1 and DDR3_B1, see p.2 No. 7) or identical DDR3 DIMM
pairs in Dual Channel B (DDR3_A2 and DDR3_B2, see p.2 No. 8), so
that Dual Channel Memory Technology can be activated. This moth-
