10Gb PCI-E NIC Network Card, Single Copper RJ45 Port, with Intel X540-BT1 Controller, PCI Express Ethernet LAN Adapter Support Windows Server/Windows/Linux/ESX, Compare to Intel X540-T1, 2-Pack

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.

The 10Gtek 10Gb PCI-E NIC with the Intel X540-BT1 controller is an outstanding network upgrade for anyone needing fast, stable, and reliable 10-gig connectivity. Installation was quick and seamless — plug it into a PCIe slot, install the drivers, and it’s instantly recognized. The Intel X540 chipset is known for its reliability, and this card absolutely lives up to that reputation. From a performance standpoint, it’s excellent. I consistently achieve full 10GbE speeds during large file transfers, virtualization workloads, and NAS-to-PC operations. Latency is extremely low, and there’s zero packet loss or connection instability. The onboard controller handles offloading efficiently, reducing CPU load and keeping system performance smooth even during heavy data transmission. Thermals are well-managed too — the heatsink keeps the card cool, and I haven’t experienced any throttling or heat-related issues. The RJ45 port is sturdy and compatible with Cat6a/Cat7 for maximum throughput. For home labs, servers, workstation builds, or high-speed content workflows, this NIC is a top-tier option at an excellent value. Enterprise-level hardware, flawless stability, and true 10Gb performance.

Worked great, I used it in a Nas and it connected right up. Super stable and not a bad price plus 10gig is amazing

Works perfectly in my QNAP NAS as stated. Now I can finally get 2-5Gbps only limited by drive IO. This NAS doesn’t support very many network cards so I’m very glad this worked!

I have been using this card for about a month in a Ubuntu 24.0.4.4 LTS desktop that performs some light duty server functions. The card is good when it works. Lately I have had a lot of issues with unstable firmware from this card while using it for server workloads through a VPN. I'm not sure if the VPN is relative however it is how I know. The VPN software will clamp off all communication saying the network connection is not available. The kernel displays errors about firmware error detected FWSM: 0xFFFFFFFF. The only way to recover from this so far is a full power off, pause, and power on. Not a reboot. For it being marketed as a server card, I wish it did not have this issue. I has happened at least 3 times in the last 4 days. I will say, it normally happens under load. So light duty use may not cause this issue. EDIT: I did update the card to use thermal paste and a noctua cooling fan and I have not seen much difference.

I brought the 2-pack Dual 10GB NIC to create a peer-to-peer static IP connection between my gaming rig and my Windows NAS. The card does need downloading and installing the driver from the Intel website. After installation of the driver, the connection shows up on the Network and Sharing Center. Great cards, no issues yet.

quite happy my tp-link tx401, kept crashing during heavy usage 10gb nas/torrent, etc.... and replace it with this, stable but a bit slower. did not crash. good stuff.

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.

Só conseguir fazer funcionar no 10G na 5ª formatação com windows 10 no 11 esquece. Recomendo 21H1 e anteriores para ficar estável apesar de funcionar na 22H2 com oscilações 1000/10g. obs. coloquem ventoinha! A X550 funciona bem no 11 23H2 e anteriores e é a próxima que vou adquirir.

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.
