R813-3 3U Xeon E5 v3 with 5x PCIex16 (3.0), 1x PCIex8 (2.0), 1x PCIex1 (2.0)



Quick Overview

Take advantage of two fully-functional PCIe x16 slots! Or you can use all 5 PCIe x16 slots at PCIe x8 link speeds. Slot Pairs 3/4 and 5/6 both support auto-switching. If one expansion card is plugged into Slot 6, the signal will be a PCIe x16 link. If cards are plugged into both Slots 5 and 6, the x16 signal link will be split between both slots as x8 link speeds.
