10G Network Card with Intel X540 Chip, 10GB PCI-E NIC Compare to Intel X540-T2, Dual RJ45 Port PCI Express X8 Ethernet Adapter Support Windows/Windows Server/Linux/Freebsd/VMware ESXi

This dual port 10G network card worked like a champ. Installed it in the system, disabled the boot from LAN options (which my system didn't like), but it works great once properly configured. It was NOT hard at all to make the BIOS changes needed OR to install the needed drivers to get it running with the OS. When I need another 2 port 10G network card, I'll go for another one of these!

Network Card has been working like a champ for over 30 days now. Before using this network card, the server was crashing when trying to move large files from workstation to server. (using a 1 GB NIC and a 2.5 GB Switch). Using with 10GB switch and this network card.

The product works, Intel drivers downloaded directly from the Intel website. The heatsink is held onto the PCB with spring loaded plastic standoffs, and onto the pads that connect the heatsink to the Intel chip. When you mount this into the PC, the heatsink is upside down, and the springs are weak and the heatsink actually slumps and the pressure comes off the heatsink pads on the Intel chip. They seem too weak and I really hope the chip does not overheat due to this loss of pressure on the chip. You can see when you turn the card upside down, the heatsink moves away from the intel chip, it is not firmly held against the chip as the plastic spring standoffs are too weak for the weight of the heatsink. The packaging was rather horrible though. A thin plastic casing with no padding inside a thin box (which was crushed), inside a thin Amazon bag, sent internationally. I am amazed it arrived here without damage.

Purchased this to direct connect my QNAP TVS-882ST3 NAS. My transfer speeds went from 108MBps to over 480 MBps which is close to the limit of the Raid setup. As I add drives I'm sure this card will be able to keep up with the transfer requirements. Note, the card will not speed up your slow network unless you connect it to other 10G cards.

Update: Removing 2 stars as item died 21 months later. The card was left alone during this time. Today it emitted a smell and died without warning. I would say that it overheated. --- Pros: Value for money, heatsink that dissipates heat without the need of a fan. Speed throughput really high at 10gbe. Cons: It can connect at 10gbe but the fallback is 1gbe - no 2.5gbe or 5gbe support. Seems to be using CPU a lot when maxing out speed. Windows drivers are not up to date. Get the Intel drivers (search for Ethernet Converged Network Adapter X540 Series) Overall, I am not sure if it's a keeper. I would like to see it work at 2.5gbe as well and use less CPU. Will test for the next few days.

Whatever you do don't get a NIC with a built in fan! The dingy little fan will fail, the card will instantly overheat and your desktop or server will start crash/reboot. A fan on a NIC is an indication of a low quality, low performance / low yield chip. This cards from XZS have a real solid heatsink. Work very well and rock solid stable for our cluster servers.

Been using with an OPNsense virtual machine running on an old Windows 10 Pro system using Hyper-V. It has not had a single issue in the months that I've been using it now.

No problems and no issues. Has been running flawlessly for over a month: I know, not a lot of time. Still, out of the box and running on a Linux install with no issues. Would and probably will buy another one. The lower rating on the tech support is because the documentation could be better.

サーバーで利用するために購入 OSはProxmoxVEで利用しているが安定して利用できている。 ある程度の発熱はあるが、製品特性上問題のない範囲内と考えている （サーバーは基本的に空調が効いた環境で内部エアフローも十分であるはず）

Excellent product. Works great with module: 10Gtek SFP+ to RJ45 Copper Module - 10GBase-T Transceiver for Cisco SFP-10G-T-S, Ubiquiti unifi UF-RJ45-10G, Netgear, D-Link, Mikrotik, Meraki, Linksys and More, up to 30m. Linux network speed reports it at 10GB. It's pegged.

特に問題なく使えています。

Good Price works well, had to download latest Intel drives otherwise flawless.
