Excellent piece of kit!
After a nightmare with Mellanox ConnectX 3 and HP NC552SFP+ cards either not working, incompatible or constantly crashing, I installed this Intel X-520 (82599) based card into my Win11 Gigabyte Z390 system. Finding drivers was a slight mission but once installed, this card worked like a champ. Tested with both DAC SFP+ and OM4 multimode fibre (Using a Mellanox SFP+ transceiver) and it ran consistently – no errors, no disconnections and excellent throughput.Tested with single / contiguous 120Gb files as well as folders containing 100Gb of small (3 & 4Mb) files, I got about 3.5 to 4.5Gbps consistent throughput. Was hoping for a bit more but will next be tweaking stuff like flow control, MTU, Jumbo frames etc. Disk IO is a bottleneck, even using EVO990 Pro NVME drives.I tested direct PC to PC connections using a DAC, then via switch (DAC on PC1, fibre on PC2) using the amazing Sodola 6 port 10Gbe managed switch sold here on Amazon for a ludicrously cheap £65 (as at Aug24). It was OK on crossover but really shone with the SFP switch.Highly recommend this card and really impressed with it. To be fair to Mellanox, their dual SFP+ card is excellent but it seems there’s a major compatibility issue between Gigabyte boards (especially Z290/390/490 chipsets) and ConnectX cards. The only time it works is in a 16x PCIe slot. It will NOT work in an 8x slot due to lanes limited to 4. No way I’m dumping my RTX4070 so this 10GTek card came as a huge blessing.

Good card.
Works well had to hunt for a driver but other than that it works well.

Good rj45 10gb nic (single port)
Easy to install. Debian pc installed the drivers automatically with no intervention required. Windows 11 found the card but could not automatically install a driver. I found in the end I had to download the full driver package from intel. Once I had done this windows installed the correct driver. No issues connected to a 10gb rj45 switch using cat 6.

Does as it says…
Using this as a 10GB NIC on a Windows 11 PC. Once installed, you must download the drivers from 10Gtek’s website. Works well and good value for money.

Easy to install, and working once the drivers are installed.
Using this as a 10Gb NIC on a Windows 11 PC. Once physically installed, the device is recognised by Windows. It works out of the box, but only at 1Gb. Download and install the drivers from 10Gtek’s website, and it was offering 10Gb after the first reboot. Works well and good value for money.

Easy route to 10G
I’ve got quite a basic PC but wanted to leverage the 10G capability of my network infrastructure, I had to change my graphics card to free up a PCI slot with enough lanes for this card. After installation (win10) it was recognised straight away, popped in my SFP+ module and I was good to go at 10Gbps! I’m getting transfer speeds of about 5Gbps when running an iperf3 test to my NAS which is great considering my limited hardware.

It was awesome in my Synology DS1817+ NAS until it wasn’t!
It was awesome in my Synology DS1817+ NAS until it wasn’t!Plug and play dual 10Gbe! The model I received was a fan version, not passive as advertised.I was super happy with this and it’s only a fraction of the price of the Synology OEM model. Worked perfectly straight out of the box. Just plug and play with the Intel 540 chip.Sadly, after less than a month the fan is knackered.Have returned and purchased a passive model.10Gb Dual LAN Base-T PCI-e Network Card, Intel X540 Controller, NICGIGA 10Gbps Ethernet Adapter, 2 * 10Gbe RJ45 Port ï¼ 10G NIC Card, Support Windows/Windows Server/Linux/Vmware/ESX

win11 10g card

This card is easy and powerful. It comes with a PC case bracket and a server-style bracket which fit my HYTE case perfectly. One hurdle is the Win11 driver install, and since I have 2 ports, I had to install the driver for both of them. Use the Device Manager “update driver” process. I assume if you are buying this level of hardware, you have some idea of what you are doing… Download the Intel Win10 family drivers, I’d go for the complete set option. After extraction, find the PROXGB>Winx64>NDI565 folder, hit enter. Yes, the NDI565 folder (completely non-intuitive, I know…). Viola NIC recognized, do this for all ports in the DM. Happy networking.

I combined the 4 1Gb ports on my Synology 2419+ to get 4Gb throughout with an ubiquiti router.I have 12 10Tb disks in raid 5.The speed was a lousy 100Mb/s at best.Now I put this 10Gb X520-DA-1 card in the synology and connected it to an SFP+ port on my switch.Now I get a minimum and stable of 200Mb/s but I think thats the max of the disks combined.I’m very happy because an original card from Synology costs about 270â¬!!!!

Très satisfait de cette carte réseau 10Gtek équipée du contrôleur Intel X540-T1. Après installation, j’ai dû télécharger les pilotes directement depuis le site d’Intel, car Windows 11 ne la reconnaît pas automatiquement. Une fois les pilotes installés, la carte fonctionne parfaitement.Pour exploiter pleinement ses capacités, j’ai activé les jumbo frames à 9000 octets. Depuis, les transferts entre mon PC et mon NAS (équipé également d’une carte 10Gb et de SSD NVMe) atteignent environ 95 % de la bande passante théorique. Les performances sont au rendez-vous, avec des transferts rapides et une latence minimale.En résumé, une excellente carte réseau pour ceux qui cherchent à améliorer leur infrastructure réseau domestique ou professionnelle.En screenshot, les débits entre la carte réseau et mon nas D923+ équipé d’une carte réseau E10G22-T1-Mini

Guter Netzwerkadapter.Funktioniert problemlos unter Proxmox ohne weitere Treiber.Durchsatz 2x 10GBit Dauerlast problemlos.Konfiguration als Trunk ebenfalls problemlos.Achtung: Sollte gut belüftet sein (beim Einsatz in 19″ Servergehäuse normalerweise kein Problem, da genug Luftzug vorhanden ist)
