iStarUSA Inc. DD-766R-2U PCIe x16 Reversed Riser Card

2U PCIe x16 Reversed Riser

The iStarUSA DD-766R-2U is a 2U riser card that routes a PCIe x16 signal to a reversed x16 slot. It is built for system integrators and server builders who must fit full-length expansion cards into low-profile chassis where standard mounting is impossible. The card changes the physical orientation of the slot without altering the electrical interface. It targets deployments in rackmount enclosures or industrial PCs that demand a specific card alignment.

Fits 2U Chassis Slot 7

This riser occupies motherboard slot position 7 in a reversed layout, allowing the add-in card to sit parallel to the motherboard inside a 2U enclosure. It frees up vertical space that a standard upright bracket would consume, enabling the use of full-height cards in shallow rackmount cases. The assembly requires a compatible motherboard with the corresponding slot placement and a chassis designed for reversed riser mounting. No additional power connectors or active components are involved in the signal path.

Passive Signal Routing Only

The unit contains no active electronics, firmware, or bundled software; it serves purely as a mechanical and electrical extension for the PCIe bus. There are no driver discs, configuration utilities, or mounting hardware included beyond the riser PCB and bracket. Installers must supply their own retention screws and verify mechanical clearance for the target expansion card. The accessory changes only the physical geometry of the slot, leaving all protocol handling to the host system and the installed card.
