AMD CrossFre™ (Mult-GPU) Technology
AMD CrossFre™ s a mult-GPU performance gamng platform. By lnkng together
two or more dscrete GPUs, CrossFre™ can sgncant mprove system graphcs
performance. It allows the ablty to scale a system’s graphcs power as needed, makng t
the most scalable gamng platform. Ths manboard wll automatcally detect CrossFre™
technology and make changes n the BIOS as needed. Follow the nstructons below to
ensure a successful two-way CrossFre™ nstallaton.
Install two AMD Radeon™ HD graphcs cards nto the PCI_E2 & PCI_E5 expanson
slots.
Wth the two cards nstalled, two CrossFre™ cable are requred to connect the
graphcs cards. Attach one sde of the cable on each of the cards by way of the
metal contacts (please refer to the pcture below). Please note that although two
graphcs cards have been nstalled, only the dsplay ports on the graphcs card
nstalled n the rst PCIe x16 slot wll work. All dsplays should be connected to ths
graphcs card.

Important
Please ensure that all graphcs cards used n CrossFre™ mode are of the same
brand and speccatons. For best compatblty wth the manboard, MSI graphcs
cards are recommended.
Make sure to connect an adequate power supply to the power connectors on the
graphcs cards to ensure stable operaton.
Only Wndows™ 7 wll support CrossFre™ mode.
