ipolex 10Gb Network Card Intel X520-DA1 Ethernet Card PCI-E NIC(E10G42BTDA), with Intel 82599EN Controller, Single SFP+ Port, 10G PCI Express LAN Adapter Support Windows Server/Windows/Linux/Vmware

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.

Worked great in my home TrueNAS server!

Very Satisfied

I mean it’s a 10gbps network card. Chances are your computer isn’t even man enough to serve 10gbps from its hard drives. Does your switch even lift 10gbps, bro? Does your Ethernet cabling have the testicular fortitude to handle all this Heman glow shine?When a NIC eats up an 8 channel PCI Express port and has a fan on it, you know it doesn’t duck around. You’re probably going to need a multi device raid to even deliver all that data. What’s nice is even if you can’t max the stream out, you have a bit of overhead so the network speed doesn’t grind to a crawl during a file transfer. Or if your network is saturated by large data traffic from multiple devices like IP cameras.If you have a solid capable NAS array, these cards really have a purpose for serving data at blistering speeds. Moving large raw movie files and such.The card itself is easy to install and the drivers were easy to find and get working.

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.

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\Winx64folders, don't go any deeper in the install search.

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.
