Mult-GPU Technology
Ths manaobrd supports Mult-GPU technology, t allows two GPUs to run n tandem
wthn a system to acheve up to twce the performance of a sngle graphcs card. To
utlze ths technology, the two GPU cards must be connected by an Mult-GPU Lnk
card.
If you ntend to use the Mult-GPU mode for better graphcs performance, please refer
to the followng nstructons.
1. Install two graphcs cards on PCI Express x16 slots. Wth two cards nstalled, an
Mult-GPU Lnk Card s requred to connect the golden fingers on the top of these
two graphcs cards (refer to the pcture below). Please note that although you have
nstalled two graphcs cards, only the vdeo outputs on the first card wll work.
Hence, you only need to connect a montor to the first PCI Express card.
Important
If you ntend to nstall TWO x16 graphcs cards, make sure that these two graphcs
•
cards are of the same brand and specficatons.
• Make sure that you connect an adequate power supply to the JPWR2 connector
(or to the power connector on the graphcs card) to ensure stable operaton of the
