Dual Channel Memory Configuration
The GA-M59SLI-S5/GA-M59SLI-S4 supports the Dual Channel Technology.
After operating the Dual Channel Technology, the bandwidth of Memory Bus
will double.
Due to CPU limitation, if you wish to operate the Dual Channel Technology, follow the guidelines below:
1. Dual Channel mode will not be enabled if only one memory module is installed.
2. To enable Dual Channel mode with two memory modules (it is recommended to use memory
modules of identical brand, size, chips, and speed), you must install them into DIMM sockets
of the same color.
3. To enable Dual Channel mode with four memory modules, it is recommended to use memory
modules of identical brand, size, chips, and speed.
The following is a Dual Channel Memory configuration table:
(DS: Double Side, SS: Single Side, "--": Empty)

2 memory modules
4 memory modules
DDRII1 DDRII2 DDRII 3 DDRII4
DS/SS DS/SS - - - -

If two memory modules are to be used to achieve Dual Channel mode, we recommend
installing them in DDRII1 and DDRII2 DIMM sockets.
