This article covers YuanLey 10G ネットワークカード デュアル RJ45 ポート 10G Base-T イーサネットカード Intel X540 Conrtoller PCIE.

Overview

The YuanLey 10G Network Card is a dual-port RJ45 10GBASE-T NIC powered by the Intel X540-T2 controller. It fits into PCI Express x8 or x16 slots, bringing 10-gigabit Ethernet to standard desktop PCs, workstations, and servers without requiring fiber-optic cabling. What sets this card apart is the proven Intel X540-T2 chipset, which delivers stable 10Gbps throughput over copper twisted-pair cables (Cat6a or better). For users who regularly move large files between a NAS and their workstation, edit 4K/8K video over the network, or run multiple virtual machines, upgrading from gigabit to 10GbE can dramatically reduce transfer times. The dual-port design also enables link aggregation or failover configurations for added reliability.

Connectivity & Compatibility

Interface: PCI Express x8 / x16 slot (x8 lanes required for full 10Gbps) Network standards: 10GBASE-T, 1000BASE-T (auto-negotiation) Supported OS: Windows, Windows Server, Linux, VMware Brackets included: Full-height (standard ATX) and low-profile (SFF) brackets * Ports: 2× RJ45 copper ports The Intel X540-T2 controller is widely supported across operating systems, with native drivers in most modern Linux kernels and Windows 10/11. The card auto-negotiates down to 1Gbps when connected to a gigabit switch, so you can install it today and upgrade your network infrastructure later.

Product Info

The YuanLey 10G NIC is available through and other online retailers, typically priced in the mid-to-high ¥20,000 range. The manufacturer advertises lifetime technical support, though the exact warranty terms should be confirmed on the product page. Market positioning: this is an entry-to-mid-range 10GbE adapter. The Intel X540 controller is a mature, well-tested design — not the newest on the market (X550 and X710 series offer lower power and advanced features), but it provides reliable 10Gbps performance at a competitive price point. It's a solid choice for budget-conscious home lab enthusiasts and small businesses.

Best Use Cases

NAS power users: If you own a 10GbE-capable NAS (QNAP, Synology, TrueNAS) and find gigabit Ethernet too slow for large backups or media editing, this card lets your PC talk to the NAS at full 10Gbps. Ideal for creative professionals working with 4K/8K footage directly from network storage. Home lab and virtualization: Running multiple VMs on VMware ESXi or Hyper-V? The dual ports allow you to separate management and data traffic, or set up NIC teaming for redundancy. The card is well-supported in enterprise hypervisors. * Small office / file server: For teams that share large datasets (CAD files, medical imaging, software builds) over a local network, upgrading the server and key workstations to 10GbE eliminates the network bottleneck without replacing all client machines at once. This card is overkill for general web browsing, email, or casual gaming. Gamers won't see lower ping from 10GbE — the bottleneck is usually internet latency, not local network speed. Also, if your motherboard lacks a free PCIe x8/x16 slot with enough lanes, installation may be problematic.

Things to Consider

PCIe lane availability: The card requires a PCIe x8 electrical connection to achieve full 10Gbps. Some motherboards run the second x16 slot at x4 or x1 electrically, which will limit throughput. Check your motherboard manual before buying. Heat output: The Intel X540-T2 runs warm under load. The included heatsink is adequate, but good case airflow is essential to prevent thermal throttling. Avoid installing it directly above a hot GPU backplate. Cabling and switch: For 10GBASE-T at full speed, use Cat6a or Cat7 cables. Cat5e may work over short distances but is not guaranteed. You'll also need a 10GbE switch or a direct crossover connection to another 10GbE device. Driver installation: Windows 10/11 usually detects the card automatically, but installing Intel's latest driver from the official site is recommended for best stability. Linux users will find the driver built into the kernel (ixgbe driver). ## FAQ
Q: Can I install this card in a PCIe x4 slot? A: Physically yes, but the bandwidth will be insufficient for full 10Gbps throughput. The manufacturer recommends at least a PCIe x8 slot. Q: What can I do with two RJ45 ports? A: You can connect each port to a different network, combine them via link aggregation (if your switch supports it) for up to 20Gbps total throughput, or configure one as a failover backup. Q: Will this card work with my existing gigabit switch? A: Yes, it auto-negotiates down to 1Gbps. You can use it immediately in a gigabit environment and upgrade to a 10GbE switch later without replacing the NIC.
