Review: Does as it says... - Using this as a 10GB NIC on a Windows 11 PC. Once installed, you must download the drivers from 10Gtek's website. Works well and good value for money.
Review: Decent dual port 10Gbe SFP+ NIC - Really impressed with this 10Gtek 10GbE dual port NIC and it's working perfectly in Windows 10. I've installed a couple of 10Gbe SFP+ modules and connected via fiber patch leads to my network and have had absolutely 0 issues. The card is a PCI Express x8 card so make sure you have a suitable slot available to plug it into. For Intel based systems some of your slots may not be directly attached to your CPU and will be limited by your chipset. I've installed the card into an x16 slot which I know will have dedicated PCI lanes and offer the best performance. The card comes in a plain cardboard box with a driver DVD and small form factor back plate. I also highly recommend downloading and installing the latest Intel drivers to leverage the full capabilities of this card (such as VLANs and Teaming etc.)

## 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

### ⭐⭐⭐⭐⭐ Fast card. Lots of features.
*by G***E on 17 September 2016*

Had trouble at first as this is a HBA type of card instead of a straight NIC. Found a slot that worked though. Very fast with lots of options. Auto detected in windows 10 and installed the drivers automagically. Not a typo :) I went to the Intel website and used those driver. Just a minor face change to the settings on device manager. This card is ace. Great price. Just get it. Though, if you've had issues with HBA cards before then be careful as it might not work for you. For example, I have a sata card that I just can't get working in this PC. It worked in my old machine. I think most pcie slots expect simple devices. This card is quite complex. If in doubt, but the more expensive simple NIC type cards.
