Innocard DP7401 PCIe Gen4 gender changer

SKU CH-4MV9-RB5Z8

Converts a PCIe 4.0 x16 slot to dual SlimSAS 8i ports with a ReDriver for 16 GT/s signal extension

  • Adapter typePCIe Gen4
  • Enables PCIe 4.0 at 16 GT/s over longer cables with built-in ReDriver
  • Supports four x4 links from a single x16 slot for flexible topologies
  • Extends signal integrity with integrated clock, PERST#, WAKE#, CLKREQ# and PWRBRK# buffers
  • Compliant with SFF-8654 1.2 and SFF-9402 1.1 pin-out standards
  • Ready indicator LED confirms AIC status at a glance

PCIe Gen4 gender changer for RTX 3080

The Innocard DP7401 adapts a PCI Express 4.0 x16 slot to dual SlimSAS 8i ports. It is built for rack servers that need to connect an NVIDIA GeForce RTX 3080 GPU through a cable-based topology. The card includes a ReDriver and clock buffer to maintain signal integrity across longer traces.

Thermals noise and power draw

The adapter is a passive add-in card with no fan or active cooling of its own. It draws auxiliary power through the slot and the onboard buffers to sustain 16 GT/s links over extended cable runs. Operating temperature and acoustic profile depend entirely on the host chassis airflow.

Bundled accessories and software

No driver disc or management utility is included; the board relies on native OS support from Windows 7 through Windows 10 and UEFI 2.3.1 or later. A green D1 LED indicates when the AIC is powered and ready. The ReDriver and bus buffers enable longer cable lengths without extra configuration.

Questions about this item

How do I install the Innocard DP7401 and what step is often missed?

Insert the card into a PCIe 4.0 x16 slot, connect SlimSAS 8i cables to the SFF-8654 ports, then enable bifurcation in the UEFI 2.3.1 BIOS so the 16 lanes split into four x4 links; skipping the bifurcation setting leaves drives invisible.

What maintenance or replacement will the Innocard DP7401 need later?

The on-board ReDriver, clock buffer and bus buffers are soldered components with no user-serviceable parts; if signal integrity degrades over time the whole adapter must be replaced.

What limit appears first when the Innocard DP7401 runs sustained workloads?

The 16 GT/s PCIe 4.0 link budget and the ReDriver equalisation range set the maximum cable length and trace distance; exceeding them causes link errors before any thermal throttle.
