10Gb PCI-E NIC Network Card for Intel X710-DA2,100MbE/1GbE/10GbE Dual SFP+ Ports, with Intel X710-BM2 Chip,10GbE PCI Express 3.0 X8 Ethernet Adapter Support Windows/Linux/VMware

I installed this network card in my custom OPNsense pc router. It was basically plug n play, although I did have to set the interface speed manually to 2.5Gb, as auto detection didn’t work. I didn’t test it with anything faster but I do get full speed at 2.5gb and I’m confident it would work fine up to 10Gb.

Works great in my OPNsense router. No issues as of this date, 2 months heavy server use.

This network card WILL NOT work with Windows 11 version 24H2. Windows did not detect the card, so I went to the Intel drivers site and found recent drivers for Windows 11. Unfortunately these drivers did not work. It did however detect the card and there were no warnings in Device Manager. Even with the recent Intel drivers installed, it still behaved as if the network cable was unplugged.So, I decided to install the card on one of my Windows Server 2025 machines and bam, Windows detected the card with no additional drivers needed. Upon searching for a solution, I found a couple instances where others were having issues with Windows 11 installs. So be advised that this card at this time is not Windows 11 compatible

Needed to upgrade my internet speed and this easy to install component is doing the job!Great price and value.

Bought this to replace a dead ethernet port on my motherboard. I liked the fact that this model had a heatsink since heat can can induce thermal throttling for these types of things and in terms of a network adapter, that will affect the transfer speeds (i.e. reviews complaining about thermal throttling for USB network adapters).Also it was cheap enough that I wouldn't feel too bad if it didn't work. A few months later after installing and it's still going strong. I get sustained 2.5gbe speeds out of it transferring files within my network to and from my server so I can't really complain.Only minor negative I can think of is it has a bright red activity light that constantly flashes on the inside of your case. This is a problem if you have a windowed side panel like I do. Not a deal breaker and can be addressed, but annoying nonetheless.

Because my server runs linux (TrueNAS), i was able to see why this card wasn't connecting at 2.5gb.Turns out, the card is CAPABLE of connecting at 2.5gb speeds but doesn't ADVERTISE (tell) that to the switch, so they always auto-negotiate at 1gb.In linux, run "ethtool [interface name. example, 'ethtool eth5']" and look at the capable and advertised speeds. This means that you need to create a service/unit file with systemctl in order to run this at bootup "ethtool -s [interface name] speed 2500 duplex full autoneg on".This is what is known as a work around. I did not pay $130 for a work around.

I ordered the X550-T2 for my pfSense build, but the first card arrived defective. I reached out to the seller, and they immediately sent me a replacement with no hassle.The new card works flawlessly in our pfSense setup, delivering reliable 10Gb performance. While the product is great, the highlight of my experience was the seller’s exceptional customer service. They resolved the issue quickly and made the process stress-free. Highly recommend both the NIC and this seller!

The thing to know about this card is it supports multiple speeds. I had a router I built that had a card with the X540 chip in it. The issue is that the X540 only supports 100Mbps, 1000Mbps, and 10Gbps. This card supports 2.5Gbps and 5Gbps. That is something that is important when setting up your network for multi-gigabit. Do yourself a favor and just spend the extra money for this card. Works great with OPNsense, just have to manually set the speed.
