Review: Fast, Reliable, and Easy to Install Network Card - This network card is exactly what I needed for faster wired connectivity. Installation was simple, and the card was recognized immediately without any driver issues. The Realtek RTL8125 chip delivers consistent and reliable speeds, making it perfect for gaming, streaming, or large file transfers. The build quality feels solid, and the card sits securely in the PCIe slot. I’ve noticed a significant improvement over my previous 1Gb network card, with stable and smooth performance. Overall, this is a high-quality, easy-to-use upgrade for anyone looking to boost their network speed. Definitely a five-star choice for home or office setups.
Review: Yes, it's compatible with your system - physically and functionally - I bought this for an HP 54L Microserver I bought in 2010 and still have in use as a lab box. I have upgraded my house network to 2.5 / 10gb (depending on the box) and wanted this to participate. The card comes with a low-profile bracket and works just fine in a PCIE 2.0 slot. Three different versions of Windows on the box recognized it immediately and this should extend the lifetime of the box until the grandmotherboard finally gives out. It worked so well, in fact, that I got a second card and dropped it in a Dell PowerEdge 720 as well. The price may seem a bit high, but it's 2 ports and I expect it'll get pulled for other use when/if either server I have gets replaced.

### ⭐⭐⭐⭐⭐ Works great, love the x4 speed and slots... get the web site driver!
*by J***R on August 17, 2025*

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.
