IO Crest 2.5 Gigabit Ethernet PCI Express PCI-E Network Controller Card 10/100/1000/25000 Mbps RJ45 LAN Adapter Converter for Desktop PC (SI-PEX24059)

Used to upgrade an older PC for use on a 2.5Gb network. Hardware installation was easy and took 10 minutes, and Windows 10 installed a driver for it so it worked straight away. However I was getting 280-odd MB/s incoming, but only 170-ish outgoing. So I installed the driver on the included CD (Realtek 8125 chipset) and that got full speed in both directions. So far seems like a great, economic way to upgrade.

Direct connection between 2 PC's, not connected to a Switch. Works great at 2.5G Speed, dead easy to install, no problems.

There is no Windows 7 driver on the disc but it can easily be downloaded from the Realtek site. Otherwise easy installation and good perfrmance.

Multigigabit networking at a bargain price. Works with Windows 10; you do have to install the drivers which come on a mini CD but it checks for updates during the install. Faultless at this price.

Installed into a full size slot on my motherboard. The card comes with 2 size brackets, with the larger bracket being fitted and the smaller size bracket in the box. Windows 10 detected the card straight away and didn't need to use the supplied driver cd. I've been running this card for 1 month now without a single issue with excellent speeds.

Easy to install. Working dull speed on windows server 19 Minimal setup. Getting great speeds

Bought as the Ethernet port on my PC suddenly decided to die, had to switch to a wireless dongle that was not capable of HD video streaming. This was so easy to install into a spare PCI slot. Windows foouns it right away and was soon getting download speeds of 200mb. Worth getting.

Upgraded it on my pc and works perfectly. No driver issues or hardware issues.

This upgrade to 2.5gig Ethernet is easy to install into a PCIe slot and drivers are included on the supplied mini CD. Many drivers are included including Windows 11, 10, Mac and Linux. Full speed is achieved using Cat 6 wire. Both full form and small form factor hardware included - easy to change out. Ethernet socket has two LED indicators for link and speed which is good since other cards may not have these indicators or have holes to see through to an LED on the inside surface of the card. The Realtek chip and the software may be able to go to 10gig in the future since there is some references in drivers and other information of the system. Maybe a firmware update in the future for this? Overall, this is a great product and very reasonable in price and support.

I bought this to test 2.5GbE on a PC that did not support it. This thing is plug-and-play, and worked everywhere I connected it. I bought it in 2021, and it's still working just as well as the day I got it!

Acabo de instalar la tarjeta de red, si costo trabajo para que mi tarjeta madre la reconociera, aunque al ser pci, y puedes conectarla en los puertos pci-e 16x, posiblemente mi tarjeta no la reconoce de este modo, y fue necesario colocarla en los pci. con eso la detecto windows sin problemas, ya solo busque el driver directo del fabricante del chipset, el cual es Realtek, y permitió que funcionara un poco mejor. A comparación de mis anteriores test con el conector de red de la tarjeta madre, si varia la velocidad de internet, pero puede que con el tiempo se ajuste y me de mejores resultados. la primera foto es del antes, y la segunda con la tarjeta

Aparte de muy buen precio para un 2.5 gigabit, mis pings bajaron de 25ms a 8ms.

Unraid loaded the driver and gave me 0 issues. Transferring large files, I was getting 2.1+ gigabit speeds. I am happy with the speed improvement at a low price and not needing to install fiber optic cable. Using a 5ft cat5e cable plugged into this and a 2.5gb Ethernet switch.
