Our take on the Supermicro AOC-2UR668G4 2U Ultra Riser 2x PCI Express 4.0 x16 Riser Card

The Supermicro AOC-2UR668G4 is a 2U Ultra riser card that adds two PCI Express 4.0 x16 slots to a compatible Supermicro 2U server. It is a system-specific part, not a general-purpose adapter: it fits Supermicro Ultra-series chassis and the motherboards those systems are built around. For anyone expanding a supported 2U Ultra server, it is the clean way to run two full-bandwidth PCIe 4.0 cards; for other systems, a generic riser or a different Supermicro part is the better match.

Questions and answers

Which servers does the AOC-2UR668G4 fit?
It is made for Supermicro 2U Ultra-series systems that specify this riser. Check your chassis and motherboard model against Supermicro's compatibility list before buying.
Does it give two full x16 PCIe 4.0 slots?
Yes. The card provides two PCI Express 4.0 x16 slots, so both can run at x16 bandwidth when the host platform supports it.
Will it work in a non-Supermicro server?
No. It is a proprietary riser shaped for Supermicro Ultra chassis, not a standard PCIe slot adapter for other brands.
Does it support PCIe 5.0 cards?
The slots are PCIe 4.0. A PCIe 5.0 card will generally run at 4.0 speed in them.
What comes in the box?
The riser card itself. Mounting hardware and cables are not included unless your system's accessory kit provides them.
