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

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.

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!

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.

I connected this to an AMD 2700 built box. I couldn't get it to connect at faster than gigabit speeds. Updated drivers, played with different settings, changed cables. Nothing. Max was gigabit speeds. My cheap 2.5gig realtek chip connects at multigig speeds so I know it isn't a wiring/device issue, its a card issue. Junk

I installed this inside my Dell T30 for my homelab.Got recognized instantly.The ports are working alone, so you can use the ports independently.Will update my review if something happens.First review date: July 2 2023

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.

Plug in play without issue in my Dell R710 Server. Proxmox recognized without having to do anything special. Tested speed hit the expected speeds.
