25G Ethernet Network Card, 2X SFP Ports, PCIe 4.0 X8, Intel E810 Controller, Support Windows 10/11/2016/2019/2022 /Centos7/ Ubuntu20/Vmware/Esxi7.0(not Support MAC)

Works perfectly on Linux. Been using it with my 10g netgear switch to share the network connections with multiple VM's on KVM/libvirt. Expensive, but worth it if you need to keep at the bleeding edge of technology, otherwise an overkill. Great to play with sriov, vm's, vf's.

after a decent wait finally gotten this 10gbe nic card. however I purchased this because there's a fan but the product sent was w/o a fan and purely heatsink. felt cheated or rather disappointed because we all know the heatsink w/o the fan, may not be as efficient.

Funciona en w11 sin instalar nada más. Funciona a 1gbps o 10gbps, no funciona a 2.5gbps. Recomiendo ponerle ventilación para evitar sobrecalentamiento.

As a solutions architect who has recently started working from home, I needed a reliable and high-speed network card to handle my upgraded home internet connection, which is now a fiber connection at 5Gbps+. I also required higher throughput to my work's datacenter. The 10Gtek 10Gb Dual RJ45 Port Network Card with X540 Controller has proven to be an excellent choice. First and foremost, this network card delivers outstanding performance. With dual RJ45 ports and the X540 controller, it supports 10Gbps speeds, ensuring that my connection remains fast and stable. This has been crucial for my workflow, as I often need to transfer large files and access remote servers without any lag. Upgrading my home internet to a fiber connection at 5Gbps+ meant I needed a network card that could handle such speeds efficiently. The 10Gtek network card has met these demands perfectly, providing the necessary throughput to my work's datacenter. This has significantly improved my productivity, allowing me to access and manage data quickly and efficiently. The installation process was straightforward, and the card works seamlessly with my Windows systems and Hyper-V servers. The packaging was fantastic, and the install was as simple as expected. However, the only negative experience I had was finding compatible drivers. Windows Update didn’t recognize the hardware, and the manufacturer’s website didn’t have any readily available drivers. I ended up going to the chip manufacturer’s website and found the appropriate driver, which I successfully installed. No driver disks or instructions were provided. The build quality of this network card is on par with what I expected, providing a solid and functional product. It feels robust enough for long-term use without being overly impressive. Additionally, the card's design ensures efficient heat dissipation, preventing overheating even during prolonged use. One feature I particularly appreciate is the network activity lights, which, while almost standard, provide clear indicators of network status and activity. The device is also void of any additional noise, making it ideal for a quiet home office environment. Additionally, the value for the money is exceptional. This network card offers high-end performance and features at a reasonable price point, making it a great investment for anyone needing reliable network connectivity. In summary, the 10Gtek 10Gb Dual RJ45 Port Network Card with X540 Controller is an excellent investment for anyone needing high-speed and reliable network connectivity. It has significantly enhanced my home office setup, providing seamless and efficient access to my work's datacenter. If you're looking for a network card that offers great value for the money, exceptional performance, and broad compatibility, I highly recommend this product. Despite the minor inconvenience with the drivers, it has been a game-changer for my workflow and connectivity needs.

Added to an older Dell 7050 for connections to a 10Gbe NAS interface and a backup network. Working great after a year and monitored speeds are right in line with specs.

This card was recognized by TrueNAS (Debian based) and once connected to my UniFi switch auto-negotiated to 10Gbps. I don’t need the dual port and wish a single port card was available for the same price. Single port was almost double the price. It has only been running a week or so. I have not conducted any performance tests.
