10Gtek 10Gb PCI-E NIC Network Card, Dual SFP+ Port, with Intel 82599ES Controller, PCI Express Ethernet LAN Adapter Support Windows Server/Linux/VMware, Compare to Intel X520-DA2(E10G42BTDA)

This card is easy and powerful. It comes with a PC case bracket and a server-style bracket which fit my HYTE case perfectly. One hurdle is the Win11 driver install, and since I have 2 ports, I had to install the driver for both of them. Use the Device Manager "update driver" process. I assume if you are buying this level of hardware, you have some idea of what you are doing... Download the Intel Win10 family drivers, I'd go for the complete set option. After extraction, find the PROXGB>Winx64>NDI565 folder, hit enter. Yes, the NDI565 folder (completely non-intuitive, I know...). Viola NIC recognized, do this for all ports in the DM. Happy networking.

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.

Working well in my Windows 11 PC. It's a home built system with an ASUS ROG Crosshair VII Hero motherboard and AMD Ryzen 9 5950X CPU. I connect my PC to an Aruba S2500 switch in the basement via OM4 fiber - my TrueNAS server also connects to the Aruba via 10Gb fiber.I was previously using a Mellanox card in my PC, but it died for some reason. This card seems to be working just as well, and I get very good thruput numbers when I test its connection to the TrueNAS server in the basement. (I didn't save the actual numbers). Recommended.

This NIC works out of the box with unraid.

No automatic driver installation for Windows 10/11. Download the intel network adapter for Windows 10 driver package from intel's website. Go to Device Manager and find the unrecognized device (listed as Ethernet Controller), and manually install the drivers in this path:Wired_driver_x64\PROXGB\Winx64\NDIS65Otherwise it seems to work well so far.

I bought multiple of these. Installed seamlessly on a ASRock B550 motherboard running Windows Server 2022 and am able to consistently reach speeds of near 10 Gbps on Cat 6a cable on a Trendnet 10 Gbps switch connecting my home network. Windows installed drivers automatically with no problems. Also installed easily on Windows 10 and 11 PCs.

Drivers for Windows 11 took an hour to find and required downloading the entire Intel network driver set just to get it installed. Constantly disconnects/reconnects every 5 seconds, so the driver is faulty. Worst of all even when connected via 40gb fiber to a machine across the room it didn't get over 1.2gbps. I'm assuming the Windows driver is at fault, and it may work fine on *nix, but this is just unacceptable. Intel needs to work with Microsoft to get the driver situation fixed so that end users don't have to deal with this kind of crap - it's not like we can troubleshoot things like we can on Linux. We have to endlessly read forums with unpaid volunteers telling us to run chkdsk over and over and over again. Replacing with NON-intel network devices. I'm looking forward to at some point never using Windows or any other Microsoft product ever again. Others who are using this device with Windows - server os or otherwise - verify your actual network throughput using iperf3.
