  • Alloy heat sink keeps temperatures stable under load

HP SAE-TXA094 Dual Gigabit NIC

This HP SAE-TXA094 adapter adds two 10/100/1000 Mbps RJ45 Ethernet ports to a desktop, server or workstation through a PCI Express slot. It uses an Intel 82575/82576 controller and complies with IEEE 802.3, 802.3u and 802.3ab standards for wired connectivity.

Suits single-slot upgrades needing two copper links

It fits PCIe x1, x4, x8 or x16 slots and includes a half-height bracket for low-profile chassis. Buyers who need fibre uplinks, 2.5G or 10G speeds, or more than two ports should look at a different adapter.

Sustained throughput with hardware offloads

The controller handles TCP/UDP checksum offload, 9.5K jumbo frames and IEEE 802.3x flow control to keep latency steady under continuous load. An alloy heatsink dissipates heat without a fan, maintaining stable operation during prolonged transfers.

Questions about this item

My motherboard only has PCIe 2.0 slots — will this card work at 2.5 GT/s?

Yes, the adapter operates on the PCIe 2.0 base specification at 2.5 GT/s and also supports 5 GT/s on newer slots.

I still run Windows XP on a legacy machine — is that OS supported?

The card lists compatibility with Windows XP, 7, 8, 8.1, 10, Windows Server, Linux, FreeBSD and DOS.

How can I confirm both RJ45 ports are linked at 1000 Mbps after installation?

Check the link and activity LEDs on each port; a steady link light indicates a 10/100/1000 Mbps connection and blinking shows traffic.
