RGEEK PCIe Bifurcation x16 to x8x8, x16 to Dual x8 Bifurcation Riser Card

Important Notice: Whether this product works properly depends on whether your motherboard, CPU, and BIOS support PCIe bifurcation. Not all motherboards support this function. Please confirm x8+x8 bifurcation support in BIOS before buying, and configure the BIOS to x8+x8 mode prior to use. ^^ This product is a PCIe bifurcation expansion kit. It allows one PCIe slot on the motherboard to be split through an adapter board and riser cables, so multiple PCIe expansion devices can be connected. It can be used for graphics cards, capture cards, network cards, RAID cards, NVMe adapter cards, and other PCIe expansion devices. ^^ PCIe 4.0 Full
Bandwidth Split Solution: This bifurcation kit adopts SlimSAS 4.0 interface, split single PCIe 4.0 x16 slot (Theoretical Data rate 256GT/s) into two independent PCIe x8 channels (Theoretical Data rate 128GT/s), retain complete PCIe 4.0 bandwidth, no speed loss for dual GPU external graphics docking, AI rendering and multi-card computing. ^^ Easy to Install and
Operate: Plug one end of the two SlimSAS 4.0 SFF-8654 8i cables into Slot 1 and Slot 2 of the main card respectively, then connect the other ends to the slots of the two breakout cards. For X8X8 split mode, plug both cables into Slot 1 of each breakout card. Insert the main card into your motherboards First PCIe X16 slot, and install your PCIe devices into the PCIe X16 slots on the breakout cards. Each breakout card requires a 6Pin power supply. Just set the corresponding PCIe bifurcation mode in BIOS, then you can start using the kit.
^^ Package Include: 1 pcs Main Card, 2pcs breakout board, 2pcs SlimSAS 4.0 SFF-8654 8i cables 75cm
