LORDWORLD 2.5 Gigabit Ethernet PCI-E Network Card Intel I225 Black

SKU CH-29W6-B61AV

Adds 2.5 GbE connectivity via PCI Express using the Intel I225 controller with TSN support, RSS, and 9.5 KB Jumbo Frames

  • 5 GbE speed over RJ45 supports 10/100/1000/25000 Mbps networks
  • Intel I225 chipset offloads TCP/UDP checksums to lower CPU load
  • Advanced interrupt handling balances traffic across multiple cores for better throughput
  • 5 KB Jumbo Frames and 256 KB TCP segmentation reduce per-packet overhead
  • TSN features IEEE 802.1Qbu 802.3br 802.1Qbv 802.1AS-REV 802.1p/Q 802.1Qav enable time-critical apps

2.5 Gigabit Ethernet PCI-E Card

This network interface card adds a 2.5 Gigabit Ethernet port to a desktop PC through a PCI Express slot. It is built around the Intel I225 controller and targets users who need faster wired throughput than standard Gigabit without moving to 10 Gigabit infrastructure.

2.5 Gbps headroom and limits

The card negotiates at 10, 100, 1000 or 25000 Mbps over a single RJ45 link. It handles typical multi-gigabit internet plans and local NAS transfers comfortably, but it cannot exceed 2.5 Gbps, so 10 Gigabit or fibre uplinks remain out of reach.

Intel I225 offload and TSN features

The controller offloads TCP and UDP checksums for IPv4 and IPv6 and performs TCP segmentation up to 256 KB. Jumbo Frames up to 9.5 KB and Receive Side Scaling distribute load across cores. Time Sensitive Networking support including IEEE 802.1Qbu, 802.3br, 802.1Qbv and 802.1AS-REV enables synchronised audio, video and industrial workloads on supported operating systems.

Questions about this item

Will the 2.5 Gigabit Intel I225 card work in an older PCIe 2.0 x1 slot?

The card uses a PCI Express interface that is backward compatible with PCIe 2.0 x1 slots. It will function at the slot's maximum throughput while still providing 2.5 GbE connectivity via the RJ45 port.

How can I verify the Intel I225 is negotiating 2.5 Gbps after installation?

Check the link speed in your OS network adapter settings or the switch port LED; it should report 2.5 Gbps (25000 Mbps) when connected to a 2.5 GbE switch with a Cat5e or better cable.

Does the box include a low-profile bracket for small form factor cases?

The product is a full-height PCIe card with a standard bracket. A low-profile bracket is not included and must be purchased separately if your chassis requires it.
