Review: Great performance, awkward fit in a desktop case - This card does what it is supposed to do. It negotiates at full speed and easily maxes out my connection without any drops or instability. Once it is set up, it just works and stays consistent. Setup was not completely plug and play for me. Windows did not install the driver automatically. I had to go into Device Manager, find the unknown network device, and manually point it to the driver I downloaded from the manufacturer. After that, the card came online and has been solid. The bigger issue was the physical fit. The metal port shield around the Ethernet connector is clearly designed with a server chassis in mind. In my standard RGB desktop case, the top of that shield hit the edge of the case and kept the bracket from seating properly. To make it work, I had to carefully trim the top of the metal shield down to roughly the height of the PCB so the card could sit flush in the slot. After that little bit of handiwork, it fit fine and has been working with no problems. Overall, performance is great and it fully saturates my line, but be aware that you need to install drivers manually and, depending on your case, you might have to do a bit of physical work to get it to fit right.
Review: Great NIC - Works perfectly. The difference in speed between this card and a gigabyte card is incredible. It was easy to install, and I was able to download and install the drivers for it without a problem.

### ⭐⭐⭐⭐⭐ It does work well on Windows 11 with a windows 10 driver follow the video in the image.
*by M***N on June 12, 2025*

I had trouble getting it working on windows 11 even trying some other tutorials I found on the internet. The seller sent me the above image with a note and the card comes up very well on both ports now. For the price this is the best value I have found even through it is using a "old" driver. It works well connected to my Ubiquiti set up. I am glad they responded with a note, I had figured I would have to use it on a server platform instead of a workstation. Follow the video from the link above and it will come right up in windows 11. It will warn you about driver signing but it is an Intel driver it is just that they are not keeping up with windows 11. Beyond that the card works well on my mother board. It has a well designed heat sink and where it is located in system it has a case fan directly cooling it. For the price you are not going to beat the card.
