Review: 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.
Review: 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.

### ⭐⭐⭐⭐⭐ Review
*by D***R on 2 August 2025*

I am recycling a 2014 AMD FX 8 core gaming PC to be a NAS to store data for my small business / SOHO network. This thing was a direct drop in / plug and play with the old PCIe 2.0 x16 slot and operates and full speed. Configuration in OpenMediaVault (Linux) was simply a matter of setting the IP parameters and enabling this controller, disabling the original onboard 1 gig and now I have network connectivity that will outstrip the SATA III disks handily... This uses an established Intel chipset so compatibility between this and the old AMD chipset is quite good. I had opted initially for another brand that worked, for 4 days... I will update my review if there are any problems but as it sits right now, it is working perfectly, and from what I can SEE anyway, it all looks quite high quality, every bit as good as the official Intel cards used in enterprise class servers at a fraction of the cost for this SOHO application.
