• 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conguration,werecommendinstallingthegraphicscardsonthePCIEX16andPCIEX8slots.)

Step 2:

(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.Conguring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
