HP 2.5GBase-T PCIe Network Card

This HP network adapter adds a single 2.5 Gb/s Ethernet port to a desktop or workstation over a PCI Express 3.1 x1 lane. It uses an Intel I225-V or I226-V controller and includes a low-profile bracket for small-form-factor cases. The card supports 2500, 1000, 100 and 10 Mb/s link speeds.

Fits standard and low-profile slots.

The x1 connector works in x1, x2, x4, x8 or x16 slots and the bundled bracket fits low-profile chassis. Buyers who need two or more 2.5 Gb/s ports from one card, or who require 10 Gb/s throughput, should look at a different adapter.

2.5 Gb/s maximum throughput over copper

The integrated MAC and PHY deliver up to 2.5 Gb/s on standard RJ45 cabling using IEEE 802.3bz. This single number decides whether the card matches your switch and cabling infrastructure.

Questions about this item

Which Intel controller version should I pick, the I225-V or the I226-V?

Both controllers deliver identical 2.5GBase-T functionality. The I225-V has been discontinued and the I226-V replaces it with improved error rates for better packet stability over longer cables, enhanced transmission accuracy and lower active power consumption.

What does the 2.5Gb/s headline speed actually deliver in a real system?

The card auto-negotiates at 2500, 1000, 100 or 10 Mb/s over standard copper cabling. Actual throughput depends on your switch, router and cable quality, but the controller supports full 2.5Gb/s line rate when the link partners and cabling meet the 2500BASE-T specification.

How does the PCIe 3.1 x1 interface limit performance?

The adapter uses a single PCIe 3.1 lane at 5 GT/s, giving roughly 4 Gb/s of usable bandwidth after encoding overhead. This exceeds the 2.5 Gb/s Ethernet line rate, so the slot does not bottleneck the network port.
