Review: Works only with a transceiver - I put this card in my five-year-old Dell Windows 11 desktop in order to take advantage of fiber internet speeds. You'll need to pair it with an SFP+ R45 transceiver to use it with Ethernet. I used a transceiver from 10Gtek and it's working great. You'll also need the latest X520 driver pack from the Intel website; I used v29.4. The auto-install didn't find the NIC so I used Device Manager's Update Driver function and pointed it to the folder where I'd unzipped the driver, and it installed fine.
Review: Works great - Works perfectly in Windows 11 and doesn't seem picky with sfp+ modules. You do have to install the driver manually but for the price I can live with that.

### ⭐⭐⭐⭐⭐ Worked Right Out of the Box Windows 11
*by J***H on April 30, 2024*

I would give this card 6 Stars if I could. Literally plugged it in and it took right off. Windows 11 recognized the card as a Intel I210 Gigabit Fiber Network Connection. I used an MTXNEO 1.25G 1310NM 20KM DDM SFP module. Interesting these cards do not have a heat sync on the main chip like most Intel cards. However, the Intel I210 card does not have a heat sync either. So absolutely no worries. At the time of this review these cards were selling for $10.99. Let me tell you, this is a steal! I will for sure be purchasing more of these cards. Will let this one run for a while. If it fails within a short period of time I will update my review. For sure not expecting any issues.
