Gigabyte GA-K8NF-9-RH user manual Dual Channel Memory Configuration

Dual Channel Memory Configuration

The GA-K8NF-9-RH 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)

	DDR1	DDR2	DDR3	DDR4
2 memory modules	DS/SS	DS/SS	- -	- -
	- -	- -	DS/SS	DS/SS
4 memory modules	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 DDR1 and DDR2 DIMM sockets.

All of the memory configurations below will cause system unable to boot. (DS: Double Side, SS: Single Side)

	DDR1	DDR2	DDR3	DDR4
1 memory module	- -	DS/SS	- -	- -
	- -	- -	- -	DS/SS
2 memory modules	- -	DS/SS	DS/SS	- -
	DS/SS	- -	- -	DS/SS
	- -	DS/SS	- -	DS/SS
3 memory modules	DS/SS	DS/SS	DS/SS	- -
	- -	DS/SS	DS/SS	DS/SS
	DS/SS	- -	DS/SS	DS/SS
	DS/SS	DS/SS	- -	DS/SS
