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.
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 configuration, we recommend installing the graphics cards on the PCIEX16 and PCIEX8 slots.)
Step 2:
Insert the CrossFire
(Note 2)
/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.

Configuration
A. System Requirements
-
Windows 10/8.1/7 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
AMD Radeon
™
HD 6800, HD 6900, HD 7800,
HD 7900, R9 200, R7 200, R9 300, R7 300, RX 400 series and above. For the latest GPU support information,
please refer to the AMD website.)

/SLI bridge connectors
-
A power supply with sufficient power is recommended (Refer to the manual of your graphics cards for the
power requirement)
(Note 1) When using dual core graphics cards, only 2-way is supported.
(Note 2) The bridge connector(s) may be needed or not depending on your graphics cards.
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 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.
The four memory sockets are divided into two channels and each channel has two memory sockets as following:
Channel A: DDR4_2, DDR4_4
Channel B: DDR4_1, DDR4_3
C. Configuring the Graphics Card Driver
C-1. To Enable CrossFire Function
After installing the graphics card driver in the operating system, go to the
AMD RADEON SETTINGS
screen.
Browse to
Gaming\Global Settings
and ensure
AMD CrossFire
is set to
On
.
Procedure and driver screen for enabling CrossFire/SLI technology may differ by graphics cards and
driver version. Refer to the manual that came with your graphics cards for more information about
enabling CrossFire/SLI technology.
C-2. To Enable SLI Function
After installing the graphics card driver in the operating system, go to the
NVIDIA Control Panel
. Browse to the
Configure SLI, Surround, PhysX
screen and ensure
Maximize 3D performance
is enabled.
