Innocard PCIe Gen4 x8 ReDriver Adapter
This Innocard adapter converts a PCIe x8 Gen 4 interface to a SlimSAS 8i connector using a built-in ReDriver. It targets system integrators and server builders extending AMD EPYC 7000 series connectivity over longer cables. The board includes clock, sideband and reset signal buffers to maintain 16 GT/s signal integrity across extended trace lengths. A green LED indicates when the add-in card is ready.
Check CPU generation and slot width before ordering
Verify the host platform uses AMD EPYC 7000 series processors with an available PCIe x8 Gen 4 slot. The SlimSAS 8i connector follows the SFF-8654 pin-out defined by SFF-9402 Rev 1.1. Ensure the target backplane or cable assembly matches this exact pin-out and mechanical keying. Confirm the chassis provides adequate airflow for the adapter board during sustained high-speed operation.
Replaces passive PCIe-to-SlimSAS adapters lacking
This unit upgrades from passive gender changers that cannot drive longer cables at 16 GT/s. The integrated ReDriver and 100 MHz clock buffer enable reliable operation over extended trace lengths where unbuffered adapters fail. The jump is worth it when cable runs exceed the reach of passive solutions or when sideband signals such as PERST#, WAKE# and CLKREQ# require buffering across the link.

Questions about this item
Does the adapter ship with any SlimSAS or PCIe cables, or must they be purchased separately?
The adapter itself is the only item included; SlimSAS 8i and PCIe cables are not supplied and must be sourced separately.
Is the 16 GT/s ReDriver version the only option, or are lower-speed variants offered?
The product is offered only with the PCIe 4.0 16 GT/s ReDriver; no lower-speed versions are listed.
What does the 16 GT/s rating mean when the card is installed in an EPYC 7000 server?
It allows each of the eight lanes to run at the full PCIe 4.0 16 GT/s speed over longer SlimSAS cables without signal loss.
