GA-EP43T-UD3L Motherboard - 16 -

1-4-1 Dual Channel Memory Conguration

This motherboard provides four DDR3 memory sockets and supports Dual Channel Technology. After

the memory is installed, the BIOS will automatically detect the specications and capacity of the memory.

Enabling Dual Channel memory mode will double the original memory bandwidth.

The four DDR3 memory sockets are divided into two channels and each channel has two memory sockets as

following:

Channel 0: DDR3_1, DDR3_2

Channel 1: DDR3_3, DDR3_4

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

1. Dual Channel mode cannot be enabled if only one DDR3 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

DDR3 sockets for optimum performance.

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 direc-

tion. If you are unable to insert the memory, switch the direction.

When memory modules of different capacity and chips are installed, a message which says mem-

ory is operating in Flex Memory Mode will appear during the POST. Intel Flex Memory Technology

offers greater exibility to upgrade by allowing different memory sizes to be populated and remain in

Dual Channel mode/performance.
