ARC2-736B-Cx
2U PCI/PCI-E combo riser card.
1*PCIe x8 + 2*PCIX-64bit/3.3V w/custom length flex cable.
The middle PCIe x8 riser connector linked with the goldfingers is connected to the motherboard PCIe x8 slot-6.an completely indepedent PCI-Express connection.
The top PCIX-64 riser connector(full) linked with a custom flex cable is connected to the nearby motherboard PCIX-64 slot, another completely independent PCI-X connection.
The bottom PCIX-64 riser connector(share) linked w/a 8-wires paddle link is connected to the next PCIX-64 slot. Connectors w/flex cable and 8-wires paddle link must be connected to the same PCIX buses 66MHz/100MHz. For one slot 133MHz expansion the PCIX-64 connector linked w/flex cable is connected to the motherboard PCIX 133MHz slot and the 8-wires paddle link is disconnected from the riser card.
The bottom and top riser connector tie together to share the common PCI-X bus and must be connected to motherboard PCIX-64 slots that have common bus signals coming from a single PCI bridge controller channel on the motherboard. Both slots must run at the same clock speed(66/100MHz) and have same VIO voltage(5V or 3.3V).
For expansion of PCIe x8 on motherboard slot-6 and 2*PCIX-64 connection on nearby slots(same PCI-X buses 66MHz/100MHz) such as Supermicro X6DHE-G2, X6DH8-G etc.
