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 ## Frequently Bought Together - 10Gtek 10Gb PCI-E NIC Network Card, Single SFP+ Port, with Intel 82599EN Controller, Ethernet LAN Adapter Support Windows Server/Linux/VMware, Compare to Intel X520-DA1(E10G42BTDA) - 10GTEK 10GBase-SR SFP+ LC Transceiver, 10G 850nm Multimode SFP Module, up to 300 Meters, for Cisco SFP-10G-SR, Meraki MA-SFP-10GB-SR, Ubiquiti UniFi UF-MM-10G, Fortinet, TP-Link and More, Pack of 2 - FLYPROFiber- LC to LC Fiber Patch Cable 1M/3ft, OM3 Multimode Fiber Optic Cable Cord, 10GB/40GB, Duplex, 50/125um, LSZH, Options: 0.2m-200m --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/34831237-10gb-pci-e-nic-network-card-single-sfp-port-intel](https://www.desertcart.at/products/34831237-10gb-pci-e-nic-network-card-single-sfp-port-intel) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-24*
