Enabling CrossFire Mode--
Connecting Two Graphics Cards:
Step 1:
Observe the steps in "1-5 Installing an Expansion Card" and install
the graphics cards in the PCIE_16 slot and the PCIE_4_1 slot.
Step 2:
Depending on your graphics cards, install the connecting bridges
on the two cards.
(Note: Procedure for enabling CrossFire may slightly differ by graphics cards. Refer
to the manual that came with your graphics cards for more information about enabling
CrossFire.)
Graphics Card Driver Setting:
After installing the graphics card driver in your operating system,
access the ATI CATALYST Control Center. From the ATI CATA-
LYST Control Center, enter the CrossFire menu and select the
Enable CrossFire checkbox to complete the configuration.
Step 3:
Connect your LCD monitor cable to the DVI-I port on the graphics
card on the PCIE_16 slot (or connect your D-Sub monitor via a DVI-
to-D-Sub adapter).
To enable CrossFire
TM
technology, you need two graphics cards that support ATI CrossFire
TM
technology.
Before You Begin--
A. Power Requirements:
Use a power supply that is able to provide sufficient power to fully support an CrossFire configuration and
other components in your system. We recommend a power supply that provides at least 20A 12V current.
The exact power requirements depend on your overall system configurations.
B. Supported Operating Systems:
Only Windows XP operating system is currrently supported by the ATI CrossFire
TM
technology.
C. BIOS Settings:
Before configuring your system for CrossFire, make sure to set Init Display First under Advanced BIOS
Features in BIOS Setup to PEG first. (Start your system with a single PCIe x16 graphics card and then go
to BIOS Setup to set Init Display First to PEG. Then install the second graphics card to enable CrossFire.)
