My current MB's NIC is a "Marvell AQtion AQC113C". My ISP speed at the wall is 2Gbps up/down. While the AQC113C worked, there appeared to be a known-bug specifically with Aquatic (Marvell branded) NICs when your speed is set to 2.5GbE on Linux systems. After a few days, the controller essentially gets corrupted and i have to reboot the system. That's frustrating as the system is used for local network AI inferencing, transcoding videos as a Tdarr node, and I often SSH/remote into it when I'm away. I need the machine on and available. I read this Intel controller has a good history of reliability on linux systems so that's why I picked it The review: Speaking for the X550-10G-1T model - Installed on a PCIe 4x slot. The notes from the seller are correct 2500/5000 speeds will need manual adjustment first but will work. Screenshot 1 is the "ethtool enp6s0" output. Note the red square those options didn't show until I ran a "nmcli connection modify" change and rebooted. Blue square shows speed I set. 2nd screenshot is the X550 controller. ISP speed test returned favorable at expected speeds 2234mbps down / 2091mbps up. So far the built-in driver is working well. Besides the manual 2500 adjustment, it was technically a plug-in-play experience. The small card fits as expected. 10gig is overkill for my intended use but I wanted "future proofing" and reliability Review: Zero issues. Well priced compared to other intel X550 cards. - Works perfectly. Downloaded driver from intel site. Functions identically to other intel X550 cards which are much more expensive. If you have a PCIx8 available the X540 is better priced and the same performance(except less power efficiency) but I only had a x4 slot. The Aquantia AQC107 cards are also x4 and much cheaper but their performance is bad unless you enable jumbo frames which isn't supported by my router, and latency & jitter & impracticality of configuring every device makes me question if it would be worth enabling even if it did. ## Features - Equipped with original Intel X550-AT2 controller chip which make the servers more stable. This product does not support firmware updates. - Compatible with Windows Server 2008/ 2019, Linux, FreeBSD* 9 and FreeBSD* 10, UEFI* 2.1, UEFI* 2.3, VMware ESXi 5.1 (Limited Functionality), VMware ESXi 5.5. - Supports 100M/1G/2.5G/5G/10G, (If the X550 NIC cannot negotiate to 2.5G/5G automatically, please try configuring it to 2.5G/5G manually). Single copper RJ45 ports(100MbE/1GbE/10GbE) let you connect to network cable for meeting the demands of data center environments. PCIe v3.0 (8.0GT/s) (Compatible with 2.0 and 1.1), X4/X8/X16 Lane. - With profile bracket and additional low profile bracket that makes it easy to install the card in a small form factor/low profile computer case/server.NOT support hot swaping. - What You Get: 10Gtek 10GbE X4 PCI-E Network Card X550-10G-1T (compare to Intel X550-T1) x1, Low-profile Bracket x1.

Straight out of the box, plug and pray worked - have it connected to a Netgear GS110MX switch that has 2 10Gbit RJ45 ports and it is working great at 400-500MBps without any optimization. I would have been using the latest DSM as of this writing so drivers exist in that DSM. Much lower cost than what the official compatible 10000BaseT cards are listed at Synology. So far so good. ## Frequently Bought Together - 10Gtek 10Gb PCI-E NIC Network Card, Single Copper RJ45 Port, with Intel X550-AT2 Controller, PCI Express Ethernet LAN Adapter Support Windows Server/Linux/ESX, Compare to Intel X550-T1 - FLYPROFiber- Fiber Patch Cable 1M/3ft OM3, LC to LC Fiber Optic Cable Cord LSZH 10GB Multimode Duplex 50/125um, Length Options: 0.2m-200m - 10Gtek 10GBase-T SFP+ to RJ-45 Transceiver, 10Gbe SFP+ Copper Ethernet CAT6a Module, up to 30m, for Cisco SFP-10G-T-S, Ubiquiti UniFi UF-RJ45-10G, Fortinet, TP-Link TL-SM5310-T and More --- ## 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.jp/products/280333969-10gb-pci-e-nic-network-card-single-copper-rj45-port](https://www.desertcart.jp/products/280333969-10gb-pci-e-nic-network-card-single-copper-rj45-port) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-26*
