Works well with Windows 10
Bought this to go into my PC to link to a Synology NAS via a Unifi XG Switch. It all just works without any messing with anything. Running windows 10 latest build.

Never see anything about 6GBps
Never seem to see a consistent throughput with this. My test includes 10g nics each side with NVME drives and i7 cpus. Usually only gets to 6Gbps, occasional spike to 8Gbps.

DO NOT WASTE YOUR TIME PLEASE
What an absolute waste of time. No driver for windows 11 and absolutely rubbish. Requested return after wasting over one day of life.

Great Value
I must say, that thise netcard are pretty good and are just working right out of the box. CachyOS (Arch Linux) found the card right away, no driver install needed. I got two of them, and have bought a pair of DAC Cables and have made direct connection between my PC. All I needed was to setup local ip adresse and up and running in no time. I used 10.0.0.1 for port 1, 10.0.0.2 for port 2, Gateway 10.0.0.10 and DNS 10.0.0.10, on the other card, I used 10.0.0.3 and 10.0.0.4 and again 10.0.0.10 for DNS and Gateway. If you want, you can either use bridge or bond to combine both ports on one of the netcard, so you instead of 10GbE get 20GbE out of the cards! Use arch wiki for how to or even just ask ChatGPT. Just remember, if you want to bind two ports to become 1, that this shall ONLY be done for 1 of the cards. I really recommend this under rated cards. Buy them and enjoy the fun with either 10GbE or 20GbE networking the EASY WAY.

parfait
Je l'utilise dans un de mes PC qui me sert de routeur. Laisse effectivement passer (sous Linux) les 10 Gb/s

Not able to get over 3gbps
Regardless of which combination of PCI-e slots and settings I used, I wasn't able to get this above 3gbps even using fibre cables and transceivers. Returned it and gave up.
