Review: Excelente producto - La tarjeta funciona perfectamente a 10 Gb Review: Easy install! Great expansion card! - My system already had 10Gb ethernet, but I disliked the heat from the translation between SFP+ and RJ46 so I got this so I could just use a DAC cable between my system and the switch. No issues installing, I just had to download the driver from Intel and install it manually, otherwise it worked pretty quickly without issues. Tested getting full 10-gig speeds through iperf3 no problem. 10Gtek seems to be establishing themselves well in the industry. Great cables, wonderful adapters, and now solid NICs to add to the list of items of theirs I've gotten and used. All work solid and as expected. ## Features - 【SPEC.】Data Rate: 10Gbps/1Gbps; Interface: Single SFP+; PCIe Type: PCIe X8 - 【Controller】Intel 82599EN controller chip, Compare to Intel X520-DA1(E10G42BTDA) - 【Supported Systems】Compatible with Windows Server 2003/ 2008/ 2012, Windows7/8/10*/Visa, Linux, ESX/ESXi* - 【Note】Only by setting up Win10 driver correctly the NIC can work on Win11!

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excelente producto *by A***R on 8 October 2019* La tarjeta funciona perfectamente a 10 Gb ### ⭐⭐⭐⭐⭐ Easy install!
