2-2 Install the Memory

Dual Channel Memory Configuration

This motherboard provides Four DDR3 memory sockets

and supports Dual Channel Technology.

When memory is installed, the BIOS will automatically check the memory in your system.

Four DDR3 memory sockets are divided into two channels :
Channel 0 : DIMM1 , DIMM2
Channel 1 : DIMM3 , DIMM4

The combinations of DIMM modules are :

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.

■

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.

For this motherboard, DIMM(1,2), DIMM(3,4) are two pairs of channels. For Lynnfield

CPU, in each pair of DIMM channel, you need to install yellow DIMM first, then install

black DIMM the second. Black DIMM can not function if no yellow DIMM is installed.

(Please refer to the silkscreen next to the DIMM slots to identify the sequence of

DIMM(1,2, 3, 4) on the motherboard.)
