Gigabyte GA-K8NMF-9 user manual Dual Channel Memory Configuration

Dual Channel Memory Configuration

The GA-K8NMF-9 supports the Dual Channel Technology. When the Dual Channel Technology is activated, the bandwidth of memory bus will be double the original one.

Due to CPU limitation, if you want to operate the Dual Channel Technology, please follow the guidelines below for Dual Channel memory configuration.

1.Dual Channel mode will not be enabled if only one DDR memory module is installed.

2.To enable Dual Channel mode with 2 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 4 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)

	DDR 1	DDR 2	DDR 3	DDR 4
2 memory modules	DS/SS	DS/SS	X	X
	X	X	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	X	DS/SS	X	X
	X	X	X	DS/SS
2 memory modules	X	DS/SS	DS/SS	X
	DS/SS	X	X	DS/SS
	X	DS/SS	X	DS/SS
3 memory modules	DS/SS	DS/SS	DS/SS	X
	X	DS/SS	DS/SS	DS/SS
	DS/SS	X	DS/SS	DS/SS
	DS/SS	DS/SS	X	DS/SS
