Our take on the SIIG LB-GE0711-S1 Dual 2.5G 4-Speed Multi Gigabit Ethernet PCIe Card

The SIIG LB-GE0711-S1 is a PCIe x4 network card that adds two RJ45 Ethernet ports running at 2.5G, 1G, 100M or 10M. It uses the Realtek RTL8125 chipset, the same controller found in most 2.5G add-in cards and many desktop motherboards, so driver support is broad. It fits standard and low-profile cases with the included bracket and supports VLAN tagging, jumbo frames up to 16K and Wake-On-LAN. It suits NAS builders, home-lab servers and desktops that need a second fast port or a link to a 2.5G switch; it is not a 10G card, so buyers wanting 10GBase-T should look elsewhere.

What reviewers say

Owner feedback on this class of Realtek-based 2.5G card is generally positive: it works once the right driver is installed and delivers the expected 2.5G throughput. Complaints center on driver setup on Linux and on cards running warm in tight cases.

What people mention
  • SpeedPraisedOwners report it reaches full 2.5G throughput when paired with a 2.5G switch.
  • DriversMixedWindows setup is easy, but Linux users sometimes have to install the Realtek driver by hand.
  • FitPraisedThe included low-profile bracket makes it fit small-form-factor and NAS cases.
  • HeatCriticisedSome owners say the card runs warm and want more airflow around it.
  • SlotMixedIt needs an x4 slot, which some buyers find wasteful for a 2.5G card.

About the SIIG LB-GE0711-S1 Dual 2.5G 4-Speed Multi Gigabit Ethernet PCIe Card
