Align the other end of the retention bracket to the retention module base. A clicking 

sound denotes that the retention bracket is in place.

Ensure that the fan and heatsink assembly perfectly fits the retention mechanism module 

base, otherwise you cannot snap the retention bracket  in place.

4. 

Push down the retention bracket lock on the retention mechanism to secure the 

heatsink and fan to the module base.

5. 

When the fan and heatsink assembly is in place, connect the CPU fan cable to the

DO NOT forget to connect the CPU fan connector! Hardware monitoring errors can occur if 

you fail to plug this connector.

This motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Modules 

(DIMM) sockets. A DDR3 module has the same physical dimensions as a DDR2 DIMM but 

is notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are 

developed for better performance with less power consumption. The figure illustrates the 

location of the DDR3 DIMM sockets:

Channel A

DIMM_A1 and DIMM_A2

Channel B

DIMM_B1 and DIMM_B2
