## Description

Product description

Review: Works great, pick the right driver - 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.
Review: Plug-and-play Intel-based 10Gb card - Plug-and-play with FreeBSD-based systems: toss it in and the Intel driver just works. As an Intel card, you are limited to Intel-compatible SFP+ modules unless you activate a kernel-parameter override. The card comes with a half-height PCIe slot backer preinstalled; you'll need to swap it with the included full-height backer to use in a standard PC. It runs a bit hot, and works best with a fan blowing on it, but I've had one running for some time with no issues.

## Features

## 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

### ⭐⭐⭐⭐⭐ Plug-and-play Intel-based 10Gb card

### ⭐⭐⭐⭐⭐ Works good w/ Proxmox 9 and OVS
*by E***S on August 22, 2025*

I got this to take the place of a Broadcom 2xSFP+ card that liked to have LACP timing fights with my TP-Link equipment and would refuse to establish links on TwinDac cables. I’ve had no issues on Proxmox 9 worked out of the box except for setting up OVS to use the new X520 card. I do not have fiber modules to test but twindac cables work fine for me on this x520.
