10Gtek® 10Gb PCI-E NIC Network Card for Intel X520-DA2, Intel 82599ES Controller, Dual SFP+ Port, PCI Express Ethernet LAN Adapter, Windows Server/Linux/VMware

Had trouble at first as this is a HBA type of card instead of a straight NIC. Found a slot that worked though. Very fast with lots of options. Auto detected in windows 10 and installed the drivers automagically. Not a typo :) I went to the Intel website and used those driver. Just a minor face change to the settings on device manager. This card is ace. Great price. Just get it. Though, if you've had issues with HBA cards before then be careful as it might not work for you. For example, I have a sata card that I just can't get working in this PC. It worked in my old machine. I think most pcie slots expect simple devices. This card is quite complex. If in doubt, but the more expensive simple NIC type cards.

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.

Excellent card, great compatibility. 10Gtek were brilliant when I encountered issues (which turned out to be settings on my switch). Great company, would definitely buy from them again.

Really impressed with this 10Gtek 10GbE dual port NIC and it's working perfectly in Windows 10. I've installed a couple of 10Gbe SFP+ modules and connected via fiber patch leads to my network and have had absolutely 0 issues. The card is a PCI Express x8 card so make sure you have a suitable slot available to plug it into. For Intel based systems some of your slots may not be directly attached to your CPU and will be limited by your chipset. I've installed the card into an x16 slot which I know will have dedicated PCI lanes and offer the best performance. The card comes in a plain cardboard box with a driver DVD and small form factor back plate. I also highly recommend downloading and installing the latest Intel drivers to leverage the full capabilities of this card (such as VLANs and Teaming etc.)

I just plugged it in and it worked out of the box.

If the drivers wont install what is the point of selling the card. I have tried the drivers linked to by the manufacturer web site, tried downloading set up files and tried with the windows device manager. What a waste of money. The customer support tried to suggest I use a fiber module which is a waste of time as use copper. Pay a bit more and get a more reliable card from a company with better support.

These are super cards. Highly recommended.

Needs a bit of work to install to Win 11 but the Support video is Clear and Precise. Maxed out the Sequential speeds 1200+ MB/s. That good I bought another. Bargain...

Worked great for a dual 10G connection from my server to a UniFi switch. True plug-and-play on my Linux build. Much more affordable than the local retail options and the build quality is top-notch. Highly recommend for any home lab or server upgrade.

funziona su server dell R720

Works good with opnsense now, its supported from kernel. No problems. Just ordered another one for my 2nd fiber link. It will have almost same kind of opnsense server than my 1st fiber link. This nic is factory unlocked.

J'étais sceptique au début en voyant quelques commentaires puis cela fait maintenant bientôt 2 ans qu'elle tourne dans un serveur Dell PowerEdge et fonctionne à merveille. Carte reconnue aussi bien sur Hyper-V, Esxi et Proxmox. Fait le job pour nous en tout cas.

The package arrived empty after ordering it here in Australia. Can also confirm this does not work in Synology DS1621+, only older Synology models.
