STARTECH ST10GSPEXNDP2 2-Port 10Gbps PCIe Network Card

SKU CH-W59P-FGXPF MPN ST10GSPEXNDP2

Adds two 10 Gbps RJ45 ports via PCIe 3.0 x4 for high-speed server connectivity

  • Rated speedMaximum Data Transfer Rate 10 Gbit/s
  • Interface typePCI Express x4 Slot
  • Supported standardsIEEE 802.3an (10GBASE-T) 802.3bz (5GBASE-T) 802.3bz (2.5GBAS
  • Connection types2 x RJ45

Ports 2 Port

  • Dual RJ45 ports deliver 10 Gbps throughput over twisted pair cable
  • PCIe 3.0 x4 interface provides enhanced bandwidth for fast data access
  • Supports 2.5GBASE-T and 5GBASE-T for flexible multi-speed deployment
  • Energy Efficient Ethernet reduces power consumption during low traffic periods
  • Wake-on-LAN and IEEE 1588 PTP enable remote management and precise timing

Dual-Port 10Gbps Server NIC

This StarTech.com adapter adds two RJ45 ports to a PC or server through a PCI Express 3.0 x4 slot. It supports speeds from 10BASE-T up to 10GBASE-T over twisted-pair copper cabling. The card targets workstations and servers that need high-throughput wired connectivity without fibre infrastructure.

PCIe 3.0 x4 lane requirement

The adapter operates in a PCI Express 3.0 x4 slot, which supplies the bandwidth needed for dual 10 Gbps links. Systems limited to x1 or x2 electrical lanes cannot deliver full line rate on both ports simultaneously. Verify the motherboard or riser provides an x4 link before purchase.

Jumbo frame and PTP offload

Hardware support for IEEE 1588 Precision Time Protocol and jumbo frames reduces CPU overhead in time-sensitive and high-volume workloads. Wake-on-LAN and Energy Efficient Ethernet are also implemented in hardware, so the host can enter low-power states without losing link.

Questions about this item

Does the 10 Gbps speed apply to each of the two ports simultaneously?

Yes, each RJ45 port can negotiate up to 10 Gbps independently, and the PCI Express 3.0 x4 interface supplies enough host bandwidth to keep both ports running at that rate without bottlenecking.

What does the PCI Express 3.0 x4 interface cap in practice?

The x4 slot carries PCIe 3.0 signalling, so the card is limited to the throughput of a PCI Express 3.0 x4 link; it cannot use wider or newer slot generations for additional bandwidth.

What slot size and bracket height does the card need to fit?

The adapter requires a physical PCI Express x4 slot (or larger) and uses a standard-height bracket, so it fits typical server or workstation chassis without a low-profile bracket.
