DualChannelMemoryConguration
This motherboard provides four DDR3 memory sockets and supports Dual Channel Technology. After the
memory is installed, the BIOS will automatically detect the specications 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 A: DDR3_2, DDR3_4
Channel B: DDR3_1, DDR3_3
Due to CPU 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, when enabling Dual Channel mode with two memory modules,
we recommend that you install them in the DDR3_1 and DDR3_2 sockets.
1-5 Installing an Expansion Card
Read the following guidelines before you begin to install an expansion card:
• Make sure the motherboard supports the expansion card. Carefully read the manual that came
with your expansion card.
• Always turn off the computer and unplug the power cord from the power outlet before installing an
expansion card to prevent hardware damage.

A. System Requirements
- Windows 8.1/8/7 operating system
- A CrossFire/SLI-supported motherboard with two or more PCI Express x16 slots and correct driver
- CrossFire/SLI-ready graphics cards of identical brand and chip and correct driver
(Current GPUs that support 3-Way CrossFire technology include the ATI Radeon
™
HD 3800, HD 4800, HD
5800 series, and AMD Radeon
™
HD 6800, HD 6900, HD 7800, and HD 7900 series. For the latest GPU
support information, please refer to the AMD website.)
- CrossFire
(Note)
/SLI bridge connectors
- A power supply with sufcient power is recommended (Refer to the manual of your graphics cards for the
power requirement)
B. Connecting the Graphics Cards
Step 1:
Observe the steps in "1-5 Installing an Expansion Card" and install CrossFire/SLI graphics cards on the PCI
Express x16 slots. (To set up a 2-Way conguration, we recommend installing the graphics cards on the
PCIEX16 and PCIEX8 slots.)
Step 2:
Insert the CrossFire
(Note)
/SLI bridge connectors in the CrossFire/SLI gold edge connectors on top of the cards.
Step 3:
Plug the display cable into the graphics card on the PCIEX16 slot.
