    Works great, love the x4 speed and slots… get the web site driver!

    Size: 2.5G RTL8125Color: 4 RJ45Verified Purchase

    Works great, like the LPB bracket inclusion if necessary. Note if using in Windows – I added this to a T420 server that only had integrated GbE, so I was looking to bump up to 2.5GbE. Windows downloaded a RealTek driver, and I was off and running. But… copies to the server were okay – 2.5GbE with occasional hangs, but only 1GbE from the unit. I figured it was PCIe bus related, so I tried all sorts of things. BUT… I finally went to RealTek, downloaded the latest Windows 10/11 drivers, and let it install… and now, I transfer 2.5GbE both ways. I like that this card is PCIe x4 as x1 is right up against the x1 speed limit, having x4 means more slots and more bandwidth to saturate the bus. Also note the cards will only link gigabit to my switch before Windows comes up, so check your link speed on your switch after boot, not on power-off link. Great deal for 4 2.5Gb ports.

    Using Proxmox, which rides on Debian 12(?) Linux. This works right out of the box with NO ISSUES at all. Full speed, I have 2 of them that form my storage network, while a normal gig card talks to my main network. Would buy again and every time from this point on. Might sell and bench this one and go for the 10g model they have.

    A solid 2.5G 4-port NIC going strong for over a month

    Reviewed in the United States on April 19, 2025

    Size: 2.5G RTL8125Color: 4 RJ45Verified Purchase

    After using this NIC for a month or so, I am overall very impressed with the device. Was easy to change the metal flange to the shorter height one. Was, of course, easy to install in the system. System runs Linux, so it immediately identified the NIC and I was able to utilize it. Performed a speed test with the 2.5G switch I have and a system with a 2.5G NIC in it with this 4-port. Received 2.45 Gbps through put (tested using IPerf3 and a Cat6 shielded cable). Would buy it again (and probably will for a next project coming up)

    Works great. Beware that some tools in Linux max at at gigabit and won’t report that it’s running at full speed. Had to do some googling to figure it out.
