AMD CrossFre™ (Mult-GPU) Technology
AMD CrossFre™ s a mult-GPU performance gamng platform. By lnkng together two
or more dscrete GPUs, CrossFre™ can sgnficant mprove system graphcs perfor-
mance. It allows the ablty to scale a system’s graphcs power as needed, makng t the
most scalable gamng platform. Ths manboard wll automatcally detect CrossFre™
technology and make changes n the BIOS as needed. Follow the nstructons below to
ensure a successful two-way CrossFre™ nstallaton.
Install two AMD Radeon™ HD graphcs cards nto the PCI_E2 & PCI_E4 expanson
slots.
Wth the two cards nstalled, two CrossFre™ Vdeo Lnk cable are requred to con-
nect the graphcs cards. Attach one sde of the cable on each of the cards by way
of the metal contacts (please refer to the pcture below). Please note that although
two graphcs cards have been nstalled, only the dsplay ports on the graphcs card
nstalled n the first PCIe x16 slot wll work. All dsplays should be connected to ths
