2.5  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-

fi guration, 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.12 

No.2 and No. 5), so that Quad Channel Memory Technology can be activated.

1.  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.

2.  It is not allowed to install a DDR or DDR2 memory module into a 

DDR3 slot; otherwise, this motherboard and DIMM may be dam-

aged.

Installing a DIMM

Please make sure to disconnect power supply before adding or    

removing DIMMs or the system components.  

Step 1.  Unlock the DIMM slot by pressing the retaining clips outward. 

Step 2.  Align the DIMM on the slot such that the notch on the DIMM matches the  

 

 break on the slot. 

The DIMM only fi ts in one correct orientation. It will cause permanent 

damage to the motherboard and the DIMM if you force the DIMM into 

the slot in 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.
