Dual Channel Memory Configurations Table

English

1-4 Installing the Memory

Read the following guidelines before you begin to install the memory:

• Make sure that the motherboard supports the memory. It is recommended that memory of the same capacity, brand, speed, and chips be used.

(Go to GIGABYTE's website for the latest memory support list.)

•Always turn off the computer and unplug the power cord from the power outlet before installing the memory to prevent hardware damage.

•Memory modules have a foolproof design. A memory module can be installed in only one direction. If you are unable to insert the memory, switch the direction.

1-4-1 Dual Channel Memory Configuration

This motherboard provides four DDR2 memory sockets and supports Dual Channel Technology. After the memory is installed, the BIOS will automatically detect the specifications and capacity of the memory. Enabling Dual Channel memory mode will double the original memory bandwidth.

The four DDR2 memory sockets are divided into two channels and each channel has two memory sockets as following:

Channel 0: DDRII1, DDRII2

Channel 1: DDRII3, DDRII4			DDRII1	DDRII2	DDRII3	DDRII4
		Two Modules	DS/SS	- -	DS/SS	- -
			DS/SS	- -	- -	DS/SS

			- -	DS/SS	- -	DS/SS
		Four Modules	SS	SS	SS	SS
		(SS=Single-Sided, DS=Double-Sided, "- -"=No Memory)
		Memory configurations below will cause DDR2 667
		memory to operate at 533 MHz (with 1066/800 MHz FSB CPU)
		and DDR2 533 at 400 MHz (with 800 MHz FSB CPU).
			DDRII1	DDRII2	DDRII3	DDRII4

			DS/SS	- -	SS	SS
			- -	DS/SS	SS	SS
		Four Modules	SS	SS	SS	SS
		(SS=Single-Sided, DS=Double-Sided, "- -"=No Memory)

Due to chipset limitation, read the following guidelines before installing the memory in Dual Channel mode.

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 according to the configurations in the first table for optimum performance.

3.Because of chipset limitations, do not populate both DIMM sockets of the same channel (e.g. DDRII1 and DDRII2) with double-sided memory modules to prevent system's failure to start or incorrect detection of memory modules.

1/2) ATX_12V_2X/ATX (2x2 12V Power Connector and 2x12 Main Power Connector)

With the use of the power connector, the power supply can supply enough stable power to all the components on the motherboard. Before connecting the power connector, first make sure the power supply is turned off and all devices are properly installed. The power connector possesses a foolproof design. Connect the power supply cable to the power connector in the correct orientation. The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not connected, the computer will not start.

•To meet expansion requirements, it is recommended that a power supply that can withstand high power consumption be used (400W or greater). If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system.

•The main power connector is compatible with power supplies with 2x10 power connectors. When using a 2x12 power supply, remove the protective cover from the main power connector on the motherboard. Do not insert the power supply cable into pins under the protective cover when using a 2x10 power supply.

3/4/5) CPU_FAN/SYS_FAN/PWR_FAN (Fan Headers)

The motherboard has a 4-pin CPU fan header (CPU_FAN), a 3-pin system fan header (SYS_FAN), and a 3-pin power fan header (PWR_FAN). Each fan header supplies a +12V power voltage and possesses a foolproof insertion design. When connecting a fan cable, be sure to connect it in the correct orientation. Most fans are designed with color-coded power connector wires. A red power connector wire indicates a positive connection and requires a +12V voltage. The black connector wire is the ground wire. The motherboard supports CPU fan speed control, which requires the use of a CPU fan with fan speed control design. For optimum heat dissipation, it is recommended that a system fan be installed inside the chassis.

6)NB_FAN (North Bridge Fan Header)

Connect the North Bridge fan cable to this header. The fan header has a foolproof insertion design. When connecting a fan cable, be sure to connect it in the correct orientation. Most fans are designed with color-coded power connector wires. A red power connector wire indicates a positive connection and requires a +12V voltage. The black connector wire is the ground wire.
