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 supported memory speeds and memory modules.)
• 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/3 Channel Memory Configuration
This motherboard provides eight DDR3 memory sockets and supports Dual/3 Channel Technology. After the
memory is installed, the BIOS will automatically detect the specifications and capacity of the memory. En-
abling 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 A: DDR3_P0_A0, DDR3_P1_D0
Channel B: DDR3_P0_B0, DDR3_P1_E0
Channel C: DDR3_P0_C0, DDR3_P0_C1, DDR3_P1_F0,DDR3_P1_F1
Due to CPU limitation, read the following guidelines before installing the memory in Dual or 3 Channel mode
Dual Channel--
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 modules, it is recommended that memory of th
same capacity, brand, speed, and chips be used. When enabling Dual Channel mode with two
memory modules, be sure to install them in the DDR3_P0_A0 and DDR3_P0_B0 sockets for primary
CPU; install DDR3_P1_D0 and DDR3_P1_E0 for secondary CPU.
3 Channel--
1.
3 Channel mode cannot be enabled if only one or two DDR3 memory modules are installed.
2.
When enabling 3 Channel mode with three, four or six modules, it is recommended that memory of
the same capacity, brand, speed, and chips be used. When enabling 3 Channel mode with three
