CAUTION 2 2-2 Install 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. ■ 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. 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 and each channel has two memory sockets as following: Channel 0 : DIMM1, DIMM2 Channel 1 : DIMM3, DIMM4 The combinations of DIMM modules are : DIMM1 DIMM2 DIMM3 Single Channel DS/SS - - Single Channel DS/SS DS/SS - Single Channel - - DS/SS Single Channel - - DS/SS Dual Channel DS/SS - DS/SS Dual Channel DS/SS DS/SS DS/SS (DS : Double Side, SS : Single Side, - : No Memory) DIMM4 - DS/SS - DS/SS ! For this motherboard, DIMM(1,2), DIMM(3,4), are two pairs of channels. 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.) 11 11 CAUTION

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 and each channel has two memory
sockets as following:
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.
CAUTION
!
For this motherboard, DIMM(1,2), DIMM(3,4), are two pairs of channels. 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.)
