10G PCIe Network Adapter, AQUANTIA AQC107 chip Binardat LAN Ethernet Controller, 10G/5G/2.5G/1G/100Mbps RJ45 NIC Card,Support PXE for Windows/Linux

5gig as advertised, fast, fit in pcie slot. Easy to install but need to download drivers from website for 5 gig. Works great.

These cards work well at a reasonable price

Plug and play, very stable, cheap and works pretty well over stress, never had a single problem! MAKE SURE YOU INSTALL THE DRIVER!!!

Works great, noticed an increased snappiness to the computer.

I tested this in 3 different machines. One of my ASUS motherboards had an issue that when you initially started the machine, the PCI-E was not active. This is NOT the fault of the card but the fault of the motherboard. For me to get the machine to boot fresh with the card active I was required to disable the onboard ethernet adapter. If you intend to use the onboard adapter and this adapter doublecheck reviews of your manufacturers motherboard before blaming the manufacturer of this board. To ensure you have setup the card properly. When you first install this, windows will install a default driver. I would double check the card works as expected by doing speed tests if you have internet speeds at 2.5Gbps. If you do not have those speeds you can setup iperf3 server and client and run a speed test between 2 computers. A poor mans version of this is to copy a large file from computer A to computer B. But if you do the copy file trick, you must ensure you hard drive speeds are at or above the 2.5G speeds. Some SSDs cap out at 100Mbs. Drives rated at 6G or 600Mbs likely will never run at those speeds. So keep that in mind when doing speed tests with data. If you noticed you are not getting expected speeds for the adapter. I would recommend downloading the realtek drivers from realtek. Once installed, you can change the adapter settings in the Device Manager to used 2.5G instead of the default often set to 1.0G. You may also want to turn on Jumbo frames. But in doing so check your router's capabilities for jumbo frames. Some routers will limit or restrict jumbo frames so keep that in mind. If turning on Jumbo frames and you speeds decrease you likely are having issues with your router. Some manufacturers, especially those with all 2.5G ports usually turn this feature on by default. Overall, after testing in 3 different machines. I plan to use this in my gaming PC. I can finally upgrade my internet speeds and take advantage of it for both my server and my gaming PC. A worthy upgrade in my mind since my day job includes having fast and reliable internet connection.

Great for a lil diy router, really good quality and couldn't be easier to install. It's always nice to have extra hardware included, and I need it for a my low profile computer build, and no extra cost is always good!

I hoped it would work in my Mac Pro with Ventura 13.7.8, but I was wrong. I wasn't able to install a driver and it was not recognized automatically.

If you use PFSense, this card does not work. The BSD operating system does not have drivers available.
