17 customers mention "Speed"14 positive3 negative

Customers appreciate the network interface controller adapter's speed. They mention it works at amazing speeds, with sustained 9GB per second speeds using it. The throughput is pretty much line-rate at 512 byte packets, but drops a little bit once you get larger data transfers. The cards really have a purpose for serving data at blistering speeds, and customers are very happy with the performance.

Customers like the value for money. They say it's a good economical option for adding dual 10Gig NICs and a great purchase.

"The NIC is a powerful asset for the low cost. But the installation process is a bit convoluted...." Read more

"...The plus to this card is that it's half the price for a new card and it works with all SFP+ modules...." Read more

"...Unplugged the fan and zip tied an 80mm noctua to it. Cheap cheap cooler on an already lower end NIC, so why did I pay over $100?" Read more

"...They perform well and have had 0 issues running 24/7 and are a good economical option for adding dual NIC capable of 10Gig..." Read more

24 customers mention "Connectivity"12 positive12 negative

Customers have different experiences with the connectivity of the product. Some say the 10Gbps link was established well for the first 5 minutes but then disconnected. Others report that it keeps dropping their connection, even with a valid IP via DHCP.

"These things have been amazing in my home lab upgrade...." Read more

"...to your in-house network feed otherwise no DHCP and the 10G connections don't com up. Highly recommended...." Read more

"...I've run it now for a number of days and I'm getting a clean 10Gbps connection in my home lab!" Read more

"...They popped right into my VMware box and were detected without any need for manual driver updates...." Read more

"If you want up to date drivers don't buy this. Intel dropped support and current drivers do not install, you need to install drivers 3 or more..." Read more

"Driver support was dropped by Intel 2 years ago. No currebt drivers support this card...." Read more

7 customers mention "Fan life"0 positive7 negative

Customers are unhappy with the fan life of the product. They mention it fails after 3 months, dies within 7 months, and overheats and shuts down quickly even when not in use.

"...This card has a fan but reports are some fans died early. I have a 2nd fan blowing on mine. The X540-AT2 draws 12.5 watts at 10Gb...." Read more

"Works good but fan failed after four months" Read more

"I bought 2, one of them died within 7 months...." Read more

An X710 without the hassle

An X710 without the hassle
The product shown is not what the received product looked like. It was a 10Gtek brand card.I was using this card on an OPNSense router build with a Gigabyte H610I DDR5 motherboard and it worked pretty well. The only issues I found was latency when playing video games. Not unplayable, but my consumer grade router did better. World of Warcraft was consistently showing 16ms latency for home and 26ms for the server. My old RoG Router showed 10ms on both with game prioritisation on. I wound up returning it and getting a brand new Dell version. The latency on that card is 10ms on both home and server without any game prioritisation on as OPNSense lacks such a feature.It wasn't a bad card. It worked with non Intel SFP+ modules and was less finicky than my current Dell card. The Dell card was also over double the price new.I am not sure what the latency issues were. Again they were not unplayable by any means. The plus to this card is that it's half the price for a new card and it works with all SFP+ modules. My Dell card only works with Intel SFP+ modules and DAC's and will only reluctantly accepts my Trendnet RJ45 module (there are no officially supported RJ45 modules per Intel). If I restart my router, I have to pull that module or the card will soft brick. Then I have to reset the router with the Intel module for it to work again and then plug the RJ45 module back in when everything boots up. The Intel card I bought as a server pull (2016 production) from eBay will only work with Intel modules and DAC's. It absolutely will not accept my RJ45 module.I can see why very few places offer the SFP+ Intel network cards. They are finicky and definitely not for novices. This card is a good alternative for people who just want a X710 NIC without the hassle.

    The NIC is a powerful asset for the low cost. But the installation process is a bit convoluted. You have to dive through Intel driver layers to directly install the 10GBe NIC driver through Device Manager. Not all that difficult, just a bit aggravating. Otherwise, solid. I used the Wired_driver_30.0_x64 and installed the driver for WIN10/11 from the
    :\\Wired_driver_30.0_x64\PROXGB\Winx64
    folders, don't go any deeper in the install search.

    My use case is a personal development network with two high end desktop workstations, one with AMD Ryzen 9 and the other with Intel i7. Both are running Ubuntu Linux 22.04.2 PRO and I am using a Mikrotik CRS306-4S-1N switch. Both Desktop systems have dual 10G NICs and cable into the switch with 6COM 6C-SFP-10G-T SFP+ 10G RJ45 Adapters and CAT8 cabling.

    As soon as everything was plugged in the systems came right up and everything was fast and sweet.
    Don't forget to plug in the backhaul cable from the switch to your in-house network feed otherwise no DHCP and the 10G connections don't com up.

    Highly recommended. This is plug and play and the most practical sense. Installation time was about an hour and that include putting boards in two machines, running cables, attaching adapters and installing switch. "Settings/Network/Ethernet/Wired/enp11s0f0 showed connected at 10000 Mb/s immediately.

    My one extra thought though is that the dual channel boards are only a little bit more, and by the time you bother to open up the box and install a board, you might as well think of the future, IMHO.

    Installed in my PC and booted up. The light on the NIC flashed and indicated it was connected to 10G but Windows showed "no internet connection". Moved to my onboard NIC (2.5Gb) and it was fine. Went back to the 10G and it worked for a while, and well. Rebooted my PC and now it refuses to detect the NIC. Tried installing generic Intel drivers, the ioplex drivers, and letting windows detect it, nothing is working. Reseated the card, rebooted, still nothing. It just doesn't get properly detected by Windows. I knew the price felt too good to be true.

    I was a bit worried about operating system compatibility, because the product desription doesn't explicitly list Windows 11 as being supported. I was prepared for manual driver installation, but I was pleasantly surprised that Windows recognized the card and automatically installed/configured the software for it. The network card works and perfoms as expected.
    I am using this network card in a generic PC with an MSI MPG Z490 motherboard (MS-7C79), running Windows 11 Pro Ver.10.0.22631. I'm using 10Gtek 10GBase-SR LC transceivers and LC OM3 fiber cables.

    Got this for my Proxmox machine; It works fine with a Windows 2019 VM but TrueNAS Scale and Ubuntu VMs not so much – they get a valid IP via dhcp but no network connectivity so I think there are issues with Linux drivers or kernel. I just ordered a SolarFlare SFN6122F which TrueNAS reports works (see TrueNAS resources: 10 Gig Networking Primer), if it does, then I’ll be returning this.

    l'ho installata su pfsense per collegarlo ad uno switch mikrotik in 10G. Il sistema l'ha visto senza nessun problema e le performance sono ottime. La consiglio per la sua facilità d'uso e per il prezzo.

    Arrived within estimate and product as described.
    For those interested, these seem to ship with SFP vendor locking disabled, so non-Intel SFP should work.

    Cheaper than a network switch so decided to use this to bridge two home PCs together. Worked great after installing drivers.

    For installing drivers, what worked for me was downloading the X540-10G-2T-X8 (JLX540-AT2) chip package from the QR code on the back of the network card.

    This takes you to an intel site where you should download "Intel® Ethernet Adapter Complete Driver Pack" after clicking "Show All". Unzip the downloaded file and go to your windows Device Manager. Here you will see some unidentified devices. Right-click each of them and click on "Update Driver".

    Next, select the option to look for drivers locally. Then, point it to the extracted intel drivers folder. Windows will automatically look for the correct drivers recursively. I had to do this process for both network interfaces on the card.

    And viola, it works perfect.

    To be fair I was a really disappointed when this card turned up. Considering how much it cost the heat sink was quite loose and wobbled about. I tried to straighten it up but it kept reverting back to its wonky state. There's a couple of plastic pegs on opposite corners of the heatsink, held in place with springs, but it looks like one of the springs was weaker than the other one and compressed fully causing the issue. Perhaps my card was faulty but this sort of thing should be picked up in QA.

    The card seemed to work and was detected fine after installing the Intel drivers from their website. This also leveraged the extra functionality provided by this card's chipset such as VLANs, Link Aggregation etc. so it clearly works and appears to be a genuine Intel chip.

    However, the heatsink got incredibly hot after only a few minutes use. I just didn't have much confidence in the heatsink doing a good job of dissipating heat, or in the plastic pins holding it on top of a chip that clearly gets really hot.

    If you are looking for a Dual port 10GbE RJ45 card I think there are better quality options out there.

    Pros:
    - Appears to be a genuine Intel chip
    - Works with Intel drivers to leverage advanced functionality such as VLANs, Link Aggregation etc.
    - Comes with low profile bracket

    Cons:
    - Expensive
    - Really poor build quality on the heatsink and installation
    - Runs very hot
