2.3 Installation of Memory Modules (DIMM)
This motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM
slots, and supports Quad Channel Memory Technology. For quad channel con-
figuration, you always need to install identical (the same brand, speed, size
and chip-type) DDR3 DIMM in the slots: You have to install identical DDR3
DIMM in DDR3_A1, DDR3_B1, DDR3_D1 and DDR3_C1 (Black slots; see p.2
No.2 and No. 5), so that Quad Channel Memory Technology can be activated.

Installing a DIMM
Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
Step 1. Unlock a DIMM slot by pressing the retaining clips outward.
Step 2. Align a DIMM on the slot such that the notch on the DIMM matches the
break on the slot.
The DIMM only fits in one correct orientation. It will cause permanent
damage to the motherboard and the DIMM if you force the DIMM into
the slot at incorrect orientation.
Step 3. Firmly insert the DIMM into the slot until the retaining clips at both ends
fully snap back in place and the DIMM is properly seated.

If only two memory modules are installed in the DDR3 DIMM slots,
then Dual Channel Memory Technology is activated. If three memo-
ry modules are installed, then Triple Channel Memory Technology is
activated. If four memory modules are installed in the DDR3 DIMM
slots, then Quad Channel Memory Technology is activated.
It is not allowed to install a DDR or DDR2 memory module into
DDR3 slot; otherwise, this motherboard and DIMM may be dam-
aged.
