Great card, doesn't like e-cores on 12th-13th Gen Intel CPU based systems...
Great value for a ConnectX-3 PCIex 3.0 x4 single port card. Windows 10/11 have a driver that will get you going, but i highly recommend you get the last provided one from nVidia. There is also an issue, on 12th and 13th gen Intel CPUs where you will have to disable e-cores for the system to boot under Windows. The last drivers nVidia provided do not handle e-cores at all and will cause the system to crash reliably. This card works with all of the 10gig SR optics and DAC cables i have. I just probably should have gone with a ConnectX-4 or 5 card, as they're not much more than these are. ConnectX-5 cards are the oldest nVidia still supports with updated drivers. All older cards are left to the mercy of the last provided drivers.Great value for a ConnectX-3 PCIex 3.0 x4 single port card.

Cheap entry into 10Gbe that works
Installed it into my TrueNAS Core server running X470D4U ASRock Rack motherboard and it was detected just fine after changing a BIOS setting .. I have it connected via a 10Gbe copper DAC SFP+ cable into a cheap unmanaged switch that has 4 x 2.5GB ports + 2 x 10GB SFP+ ports. I can't test actual throughput though as my PC's are only 2.5GB

It just works!
One of the best ways to add sfp+ to your Windows or Linux computer. Windows and Linux will load the driver automatically so you don't need to worry about finding it online. You can also upgrade the firmware on the card but I haven't noticed a difference so I probably wouldn't bother (unless you're having issues).
