2.5 Installation of Memory Modules (DIMM)

y Modules (DIMM)

This motherboard provides two 240-pin DDR2 (Double Data Rate 2) DIMM slots and
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) 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 A (DDRII_1 and DDRII_2; Yellow slots; see p.11/12 No.
6), identical DDR3 DIMM pair in Dual Channel B (DDR3_A1 and DDR3_B1; Green
slots; see p.11/12 No.7), or identical DDR3 DIMM pair in Dual Channel C (DDR3_A2
and DDR3_B2; Pink slots; see p.11/12 No.8), so that Dual Channel Memory Tech-
nology can be activated. This motherboard also allows you to install four DDR3
DIMMs for dual channel configuration, and please install identical DDR3 DIMMs in
all four slots. 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 yellow
slots (DDRII_1 and DDRII_2), in the set of green slots (DDR3_A1
and DDR3_B1), or in the set of pink slots (DDR3_A2 and
DDR3_B2).
