I have a few of these on my windows 10/11 machines. If I remember
correctly it might require a firmware upgrade. I may have also booted in
to linux to change the mode on them as well.
If not I have had good luck with the x520 and x710 Intel cards too.

I thought that might have been the problem, I tried to run the
commands to change it, but all attempts were met with errors saying
the option on the card was not supported.

Chances are that card is in infiniband mode and need a quick swap to
ethernet mode with their utilities. For cheap simple windows I
would say grab an x710 intel based card, pretty cheap now a days.

Subject: [AFMUG] 10 Gig PC Adapters
I'm looking to change the 10G adapter in my Windows11 PC. I have a
Qlogic BCM57810 now, but I think that it's causing my PC to randomly
crash. I picked up a Mellanox ConnectX-4 LX, and windows recognized
it, and both windows and the Fiber switch show the interface up at
10G, but it refuses to get a DHCP Lease. I even tried booting into
Linux with the same result.
I don't have to use fiber SFP, but I have a lot of Fiber SFP's laying
around. Are there other workstation 10G cards I can try with windows
drivers?
