Review: La tarjeta funciona perfectamente a 10 Gb
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.

## Questions & Answers

**Q: What's the difference between the x540-t2 and x550-t2 ?**
A: The X520 and X540 have a PCIe 2.0 x8 interface, which has 32Gbit/s bandwidth.
The X550 has a PCIe 3.0 x4 interface, which has 32Gbit/s bandwidth.

The single-port versions may be used in slower slots: X520-T1/DA1 or X540-T1/DA1 will work in a PCIe 2.0 x4 slot (at 16Gbit/s); the manual says the T550-T1 should work in a PCI 2.0 x4 slot as well, although I haven’t tried it.

**Q: Has anyone actually gotten close to the 10gbps connection speed for this card?  pcie 2.0 has limit of 5 gt/s or about 4gpbs max.  so can it be 10gb?**
A: The card is PCIe 2 with x8 lanes, which is 4 GigaByte per second. 4 GigaByte is the same as 32 GigaBit, so it should handle 10 GigaBit just fine.

**Q: Will this card negotiate down to a pcie gen 3 x2?  i think my only free x4 slot only runs in x2 mode which is why i'm asking.**
A: No, please kindly note that the X550-T1 supports PCIe v3.0 (8.0GT/s) (Compatible with 2.0 and 1.1) X4/X8/X16 Lane, and it does not support X2.

**Q: does this work with windows 11?**
A: I have not gotten it to work with windows 11. The seller says to install drivers 26.7 but those dont work

*by R***A on 8 January 2026*

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.
