Dual Channel Memory Configuration
The GA-MA69VM-S2 supports the Dual Channel Technology. After operating
the Dual Channel Technology, the bandwidth of Memory Bus will add double.
Due to CPU limitation, if you wish to operate the Dual Channel Technology,
follow the guidelines below:
1. Dual Channel mode cannot be enabled if only one DDR2 memory module is installed.
2. When enabling Dual Channel mode with two or four memory modules, it is recommended that
memory of the same capacity, brand, speed, and chips be used and installed in the same
colored DDR2 sockets for optimum performance.
The following is a Dual Channel Memory configuration table:
(DS: Double Side, SS: Single Side, "--": Empty)
2 memory modules
4 memory modules
DDRII 1 DDRII 2 DDRII 3 DDRII 4
DS/SS DS/SS - - - -
- - - - DS/SS DS/SS
DS/SS DS/SS DS/SS DS/SS
If two memory modules are to be used to achieve Dual Channel mode, we recommend
installing them in DDRII 1 and DDRII 2 DIMM sockets.
