SIIG Dual-Port Gigabit Ethernet PCIe 4-Lane Card - I350-T2
Upgrade your workstation or server with the SIIG Dual-Port Gigabit Ethernet PCIe 4-Lane Card, driven by the trusted Intel I350-T2 chipset. This easy-to-install PCI Express 2.1 x4 adapter adds two independent Gigabit Ethernet ports, delivering reliable, high-speed connectivity for multitasking, virtualization, data transfers, and streamlined network management. Ideal for expanding network capacity in desktops, workstations, and small servers, the I350-T2-based card blends robust performance with straightforward setup, giving you greater control over traffic, segmentation, and throughput without the need for complex configurations.
- Two independent Gigabit Ethernet ports for flexible networking: The I350-T2 controller powers two separate RJ-45 ports, enabling you to run concurrent networks or segregate traffic for backups, storage access, virtualization, or management. Each port supports 10/100/1000Base-T speeds, so you can maximize bandwidth on both connections while maintaining reliable performance across your environment. This dual-port design is perfect for small offices, home labs, and enterprise-grade workloads that demand parallel data streams without bottlenecks.
- High-bandwidth PCIe 4-lane interface: Built on PCI Express 2.1 x4, this card provides ample bandwidth to handle peak network loads, large file transfers, and multi-VM traffic without compromising responsiveness. The x4 design ensures headroom for heavy workloads and reduces congestion between the motherboard and the NIC, which translates into smoother streaming, faster backups, and improved overall system efficiency when other peripherals are in use.
- Reliable Intel I350-T2 chipset for stability and compatibility: The dual-port NIC leverages Intel’s well-regarded I350-T2 controller, renowned for stable performance, solid driver support, and efficient power management. With a track record of compatibility across a range of operating systems and environments, this chipset provides dependable throughput for daily tasks, virtualization pipelines, and data-center-grade workloads while keeping latency low and CPU overhead manageable.
- Easy installation with plug-in convenience: The SIIG card is designed for straightforward integration into compatible desktop or server systems. After inserting the PCIe card into an available slot and securing the bracket, connect your RJ-45 cables to the two ports. Operating system drivers from Intel and SIIG typically recognize the device automatically, and you can install or update drivers to optimize performance. The simple plug-in approach means you can expand network capabilities quickly without complex configurations or additional hardware.
- Ideal for multi-network, virtualization, and network segmentation: This dual-port NIC shines in scenarios requiring separate networks or VLAN-enabled environments. You can dedicate one port to management or storage traffic while using the other for regular data traffic, guest networks, or virtualization back-end communication. The dual-port design offers practical flexibility for developers, IT professionals, network engineers, and home-lab enthusiasts seeking granular control over traffic flows, redundancy, and workload isolation.

How to Install SIIG Dual-Port Gigabit Ethernet PCIe 4-Lane Card - I350-T2
Install this card with care to ensure optimal performance and reliability. Follow these practical steps to add dual Gigabit Ethernet ports to your system:
- Power down the computer and unplug the power cord. Open the chassis and locate an available PCI Express slot that matches the card’s interface. The card uses PCIe 2.1 x4, so insert it into a PCIe x4 (or larger) slot and verify there is adequate clearance for the bracket and connectors at the rear of the case.
- Gently seat the card into the slot until it is firmly seated. Secure the bracket with a screw to keep the card firmly in place and prevent movement during operation. Ensure no cables or components are pinched or obstructing any fans or airflow.
- Reconnect power, boot the system, and allow the operating system to recognize the new hardware. If the OS does not automatically install drivers, download the latest Intel I350-T2 drivers or use SIIG’s driver package from their official site. Install the drivers and reboot if prompted to ensure the NICs are properly initialized.
- Connect your network cables to the two RJ-45 ports on the card. Use quality CAT5e/CAT6 cables appropriate for your network speed, and confirm link indicators on the ports show activity and link status. Configure IP settings through your OS or DHCP server as needed for each network interface.
- Configure advanced settings if required: consider enabling features supported by your OS and drivers such as jumbo frames, VLAN tagging, link aggregation (if supported by your switch), or custom network profiles. For virtualization or NAS-related tasks, assign distinct networks to each port to maximize throughput and reduce contention.
Frequently asked questions
- What does this card add to my system? It adds two independent Gigabit Ethernet connections via a single PCI Express x4 card, enabling dual-port networking for faster data transfers, network segmentation, and flexible traffic management in desktops, workstations, and small servers.
- Which PCIe slot does it require? The card uses PCI Express 2.1 x4, so install it in a PCIe x4 (or larger) slot on your motherboard. Ensure there is enough space inside the chassis for the card and the cables you plan to connect.
- Are both ports capable of full Gigabit speeds? Yes. Each port supports 10/100/1000Base-T, allowing you to maximize throughput on both connections when your network and hardware permit.
- Is there driver support for common operating systems? Intel I350-T2-based NICs typically have broad driver support across Windows and Linux distributions, with drivers available from Intel and SIIG. Check the latest driver packages for your OS to ensure optimal performance and compatibility.
- Can I use the ports for different networks or VLANs? Yes. Each port can be configured independently for separate networks, or used in tandem with VLAN tagging and advanced networking features supported by your OS and switch infrastructure, providing flexible network topology and security options.
