Nice!
Worked great on install on an old Z370 Motherboard. Used provided driver by QR code download. Easy and I am getting 2.3 gb downloads. Highly recommend this 2.5 gb pci-e card.

Easy to use and negotiates 2.5 Gb
Plug and play no issues on Windows 11. Didn't have to find drivers or anything.

Boy, did this up grade my machine.
Boy, did this up grade my machine. I have just gotten true fiber installed to the house and found that the promised speed just was not there. The technician told me to turn up the speed on my PC. It was then that I found out that my mother board was the speed limiting issue. Once installed - wow, smoking fast. Compatible with my windows machine and software. Installation was easy - software/driver took a little time but all the work was well worth it. So far, no function or stability problems. Over all I am pleased with the purchase.

AQC113 - Good but confusing driver issues...
Driver info and instructions for the 10GB Marvell AQC113 controller is absolutely terrible! If you read the instructions that come with the controller it says to scan the QR code on the hardware to download the driver... this takes you to an intel driver download website which IS NOT THE CORRECT DRIVER. Also, if you go the the GigaPlus website and look for the correct driver, it is not there either. Ridiculous. For appropriate driver you must go to the Marvell website (which is in Chinese - use your browser's translate function), scroll down the bottom and select Marvell public drivers and then AQC 113. That should save you the headache that I just experienced trying to get this card to operate faster than 1gb+- speeds. Other than that, this card has good reviews for reliability and runs significantly cooler (and cheaper) than the X540/X550's.

Work as expected
I bought 2 of these for my older pc's after getting 2 gig internet. They were easy to install and windows 10 and 11 found them. I still installed the manufacturers driver from thier web page. Speed tests were bouncing around 2.1 and 2.3 gig down and up. Now I built new pc's and put one in an old dell workstation and am using it as a game server. No one has had any trouble with connections.

Just works
Setup background: I needed a 2.5gbe adapter for my Unraid server. Server is a hodgepodge of ancient hardware (intel i7 2600 based). It's also space constrained in a 2U rack case, so low profile bracket was required. Tried this item and aside from my own lack of preparation, it worked perfectly at rated speed. No weird driver install required. Tip for those upgrading Unraid boxes, just make sure that you either have GUI access via ipmi or a local monitor/keyboard or set all your network stuff to auto ahead of time to avoid losing network access while the new card is picked up as default but remains unconfigured. Overall I'm very happy with this purchase and would get more if necessary.

This Dual-Port 10Gbe NIC worked very well in Windows Server 2019
This Dual-Port 10Gbe NIC, equipped with the X520 (82599ES) Ethernet controller, worked very well in Windows Server 2019, using both 10Gbps SFP+ ports. It delivers 10Gbps, as advertised. This LAN 10G PCIe network adapter features independent dual SFP+ ports for connecting 10Gb SFP+ modules/AOC/DAC, and is compatible with PCIe X8 and X16 slots. It’s important to note that this adapter is only applicable to PCIe ports and not PCI slots.

Different size plates which Is useful for fitting in to your case. You may need to Google drivers for this before it functions as windows does not (or didn’t for me) discover it. Once installed however this thing works perfectly and is very quick

Ich kann mich den guten Rezensionen hier nur anschließen. Wir haben zwei dieser Karten im Haushalt, um unsere Geräte mit 2.5GBit/s an den Router anzuschließen. Unter Linux funktioniert die Karte via Plug and Play mit voller Geschwindigkeit, unter Windows hat es bei uns ein manuelles Installieren der originalen Treiber gebraucht, da die Windows-Treiber die Karte auf 1GBit/s begrenzt haben. Unsererseits uneingeschränkte Kaufempfehlung

la scheda è stata subito riconosciuta dal sistema senza installazione di driver particolari e di facile montaggio. E' con dissipatore di calore. La mia connessione e' passata da 1 gb a quasi 2,3.Consigliata.

Scheda di Rete 5G perfettamente funzionante, svolge il suo lavoro egregiamente. Lavora solamente con 2.4Gbps, il massimo che le reti possono fornire, ed è fantastico.

This worked perfectly on my PC. Just a quick backstory: This should not have even been an option for me but unfortunately I purchased the MSI Pro Z790-A motherboard that has the defective Intel I-226 LAN chipset (SOOO disappointed with Intel...). I already did an RMA on a previous motherboard ( an ASUS motherboard that came with the same defective I-226 chipset) and I did not have the patience and time to return the MSI motherboard so this was my alternative. Very simple plug and play device that instantly connected to the internet without any issues. It only runs at 2.5Gbps but this is good enough for my daily use.
