EVGA Classified SR-2 Motherboard

PCI-E x16 Slots

These seven PCI-E x16/x8 slots are reserved for graphics cards, and x1/x4

devices. The bandwidth of the x16 slot is up to 4GB/sec (8GB/sec

concurrent). The design of this motherboard supports up to Four PCI-E

graphics cards using NVIDIA’s SLI technology with multiple displays.

When installing a PCI-E x16 card, be sure the retention clip snaps and locks

the card into place. If the card is not seated properly, it could cause a short

across the pins. Secure the card’s metal bracket to the chassis with the screw

used to hold the blank cover.
