- H!Fiber 10Gb PCI-E Network Card NIC, Dual RJ45 Copper Ports, Compare to Intel X540-T2, with Intel X540-BT2 Chip, PCIe X8, 10Gbase-T Ethernet LAN Adapter Support Windows Server/Windows/Linux/VMware ESX

Works perfectly in my UDM Pro.

This is a very fast PCIe card for your ethernet connection. We build custom computers, and many of our clients request that a 10G ethernet card be included with their build. Unfortunately, many are mistaken as to the usability of this board with their present circumstances. Our offices have a 10G network, so all the computers are equipped with 10G cards to communicate with each other at about that speed. Our internet, however, is only 2G, so regardless of the 10G cards in the computers, we only get 2G speed from the internet. You can put this card in your computer, but unless your other computers on your internal network also have 10G cards, you will only communicate at the speed of the slowest computer you are addressing. The same is true with the internet speed. If your internet speed is 1G, that is the speed at which your computer will receive data from the internet regardless of the 10G card in your unit. When internet providers offer 10G service, we will sign up and then have the 10G speed from the internet. As an aside, also realize that all the internet providers limit your upload speed to the internet because they don't want people running a website from your home or office; they fear the traffic you may put on their lines.

I recently upgraded my home networking from 1 Gbps to a mixture of 2.5Gbps and 10Gbps. I used these NICs on my two Windows desktop computers. Once installed and configured they worked like a charm. The two disappointments were A) the NICs did not come with drivers and it was a bit of a challenge to get the correct ones located and installed; and B) Microsoft Windows 10 and 11 will no longer support trunking, so I could only get 10Gbps speeds on a single connection rather than 20Gbps - which is not the fault of the NIC provider, but nonetheless disappointing.

Easy install and setup. Latest drivers are on Intel's website. Drivers are installed through the "Device Manager" function in Control Panel on Windows 11

Works as expected. It comes with a small form factor plate so you can swap out to fit your SFF computer. You just seat it into your expansion slot, fire up the computer, log in, and install the driver that comes with it (CD).

Taking one star off, I thought this card would do 2.5 gig - It does not, it is a chipset issue, not a driver issue. Not a problem, put the card into a server on my 10 gig network. Would have loved it to do 2.5 gig - no issues with the card, easy setup and it works. using in Proxmox, Checked on OpenSuse and it worked Speed was right on - though I really didnt check all that much - I dont notice any heat issues on the home server, with a NAS on it.

I purchased two, one for my NAS and the other for my computer. I upgraded to a 10Gbe network. When it connects, it works and the speeds are there but it disconnects constantly and it does not make a connection most of the time. I have to restart or keep giving it a static IP. I replaced them both with a different brand and I no longer have that problem. I am not sure if it was having a hard time talking to TrueNas or my router but a different brand fixed my issues.

I bought two of these cards, each for use in two different systems. The fan bearings died on one within a month, and then about two months after that, out of nowhere the fan died in the other one. Replaced each with 10gb TrendNET cards with a heatsink, each of which have been fine. They worked fine while they lasted, but I would not buy them again.
