2.5.2 DDR2 Memory Slots 

This motherboard provides four 240-pin DIMM slots for Dual Channel DDR2 800/667 memory 
modules with memory expansion size up to 8GB. 

     

 

•  To reach the optimum performance in dual-channel configurations, install identical DDR2 

DIMM pairs for each channel. 

•  Install DIMMs with the same CAS latency. To reach the optimum compatibility, obtain 

memory modules from the same vendor. 

•  Due to chipset resource allocation, the system may detect less than 4GB of system memory 

in the installation of four 1GB DDR2 memory modules. 

 

There are several methods of different DDR2 configurations depending on how the DIMMs are 
populated on each system memory channel: 

•  [Single Channel]: only one channel is populated.
