ATi CrossFire (Multi-GPU) Technology
ATi CrossFire (Multi-GPU) technology is an exciting new technology developed by ATI
that allows the power of multiple Graphics. CrossFire requires a CrossFire Edition
graphics card and a compatible standard Radeon (CrossFire Ready) graphics card
from the same series. To utilize this technology, always install the CrossFire Edition
graphics card in the First mazarine PCIE x16 (PCI_EX1) slot and install the CrossFire
Ready graphics card in the Second blue PCIE x16 (PCI_EX4) slot. The mainboard can
auto detect the CrossFire mode by software, therefore you don't have to enable the
CrossFire in BIOS by yourself. Following the process below to complete CrossFire:
1. Install the CrossFire Edition graphics card in the mazarine PCIE x16 (PCI_EX1)
slot and install the CrossFire Ready graphics card in the blue PCIE x16 (PCI_EX4)
slot.
2. With two cards installed, an CrossFire Video Link cable is required to connect the
golden fingers on the top of these two graphics cards (refer to the picture below).
Please note that although you have installed two graphics cards, only the video
outputs on the CrossFire Edition graphics card will work. Hence, you only need to
connect a monitor to the CrossFire Edition graphics card.
Important

appearance of your mainboard may vary depending on the model you purchase.
2. If you intend to install TWO graphics cards for CrossFire mode, make sure
that:
a. these two graphics cards are of the same brand and specifications;
b. these two cards are installed on both PCIE x16 slots.
3. Make sure that you connect an adequate power supply to the power connec-
tor on the graphics card to ensure stable operation of the graphics card.
