Gigabit Ethernet Network Adapter with Intel I350 Chip - Quad RJ45 PCIe

In this review the Gigabit Ethernet Network Adapter with Intel I350 chip proves itself as a workhorse for small servers and workstation upgrades; the single biggest reason to buy is reliable, hardware-accelerated gigabit networking across four copper RJ45 ports. The reviewer found the adapter offers the original Intel I350 controller benefits such as TCP/UDP checksum offloading and TCP segmentation support, making it useful where CPU overhead matters. Installation is straightforward with drivers available from Intel and the card ships with both low-profile and full-height brackets for different chassis.

Key Features

• Intel I350 controller: Provides integrated hardware acceleration to reduce CPU load during heavy network traffic for smoother transfers and lower latency.
• Quad RJ45 ports: Four gigabit copper ports let a single PCIe x4 slot serve multiple network connections without extra switches or adapters.
• PCI Express v2.1 x4: Compatible with x8/x16 slots for flexible installation in a variety of motherboards and servers.
• Wide OS support: Drivers and compatibility span Windows, multiple Linux kernels, FreeBSD and VMware, so it works in mixed OS environments and virtualized hosts.
• Advanced offloads and virtualization: Features like SR-IOV, VMDq, RSS, PXE, iSCSI and Jumbo Frames support improve throughput in virtualized and storage networks.
• Included mounting hardware: Comes with both low-profile and full-height brackets so it fits standard desktops and ultra-thin servers without extra purchases.

Who It's For

Network administrators, small business servers, and power users who need multiple reliable gigabit ports in a single expansion slot will appreciate this card. Its hardware offloads and virtualization features suit hypervisor hosts and NAS or iSCSI endpoints where CPU cycles must be conserved.

Casual users with only a single Ethernet need, or those requiring 10GbE speeds, should look elsewhere; this product targets gigabit copper networking and does not replace higher-speed fiber or 10 gigabit solutions.

Pros & Cons

Pros

• Original Intel I350 silicon delivers consistent, enterprise-grade network offloads and stability.
• Four independent gigabit RJ45 ports provide flexible Ethernet provisioning from one PCIe slot.
• Broad operating system support makes it suitable for Windows, Linux distributions and VMware hosts.

Cons

• Limited to 1 Gbps per port, so it is not suitable where 10GbE throughput is required.
• Requires driver installation from Intel for some older OS versions, adding a step for initial setup.

Specifications

Our Verdict

The Intel I350-based quad-port gigabit adapter is a pragmatic choice for anyone needing multiple reliable copper gigabit connections in one slot; it delivers strong hardware offloads, broad OS support and flexible mounting at a sensible price. Buy it if you need dependable 1 Gbps ports and virtualization features on servers or workstations; skip it only if you require multi-gig or 10GbE speeds.

Frequently Asked Questions

Does it support virtualization features like SR-IOV?
Yes. The adapter supports SR-IOV, VMDq and other offloads useful in virtualized environments.

Will it work in older PCIe slots?
It uses PCIe v2.1 x4 and is compatible with x8 and x16 slots; check motherboard physical spacing but electrical compatibility is fine.

Are drivers included for Linux and Windows?
Drivers are available on the Intel website and the package provides a driver CD; supported OS lists include Windows, various Linux kernels, FreeBSD and VMware.
