    These work great, they are infact pcie 4x so they can be used fully with a m.2 nvme socket as long as it can do genuine pcie 4x, I have this modded into a jonsbo n2 along with a dual port 25gb sfp nic to bridge my 10gb network to a 25gb local lan setup, it works great

    Fast delivery, the card seems new. The package wasn't too big so it could easily fit into my mail box. I didn't have the time to properly test it. I think it would need a firmware update (not sure tho). good price, recommend 100%

    Received with fiber transceivers installed (bought in a separate purchase from Winners Hardware). All working perfectly. Good value and arrived in excellent condition. Will buy from again! Thank you!

  • 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.

  • 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).
