10Gb Dual LAN SFP PCI-e Network Card, Intel 82599(X520-DA2) Controller, NICGIGA 10Gbps Ethernet Adapter, 2 * 10Gbe SFP Port, 10G NIC Card, Support Windows/Windows Server/Linux/VMware

Out of the box this was not running at the 2.5Gb speeds (even though Windows reported it as running 2.5Gb) it was staying around 900mb with iperf3 test between 2 other machines on network that both have 2.5Gb NICs. Using the QNAP 2.5Gbe unmanaged switch for 3 PCs that all have 2.5Gbe NICs. They are segmented on their own VLAN coming from pfsense firewall appliance which also has 2.5Gbe. After updating the drivers from the Realtek site as per the pamphlet that came in the box along with a small form factor screw driver and 2 screws (using case screw to match black aesthetic) and the 2 I/O plates, then it unlocked the full menu in the interface's controller properties. Also was getting closer to the 2.5Gb speeds on local network, RDP feels smoother and stable connections without drops. There is some irregularity in the iperf3 tests though. Not getting the irregularities from 3rd PC to main PC so not sure if it's driver related or just an issue with the Realtek chipset of this card. Overall though satisfied with the price to performance and hope there will be future driver updates, not counting on it though. For what I need it to do, be a stable RDP connection it seems to be holding strong and helps not feel laggy like it did with the default 1Gb port on the X370 Taichi Mobo. This is an improvement. If you do want a blacked out PCB and the bright green LED isn't visible while doing work then this is a good 2.5Gbe card. Also make sure you get the latest driver from Realtek, out of the box is not fully unlocked. Happy packets :)

I needed a second network card for my pc and this does the job. It’s pretty fast, didn’t need any extra drivers (I run windows 11) and works well. I use it to directly connect my NAS. No issues at all.

Works great for my opnsense/pfsense router

Card works well but doesn't support port trunking under Windows 11 Home/Pro Environment due to Intel disconntituing they "Port Teaming" function after Windows 10. Haven't tried it in Server or Windows 10 OSs. Supports Jumbo Frames Slot alignement is right on and installation is easy. Doesnt seem to heat up much.

Fix for Onboard Network card not working. Straight forward and easy to install.

Works very well with TrueNAS. Easy plug and play installation.

Works at 5 after updating driver

I bought this 10GbE Base-T adapter for my OPNsense firewall. It worked perfectly at first and was immediately recognized by the system. Performance was great for the first few months. After four months, my firewall suddenly stopped processing traffic. The card is still detected correctly by OPNsense, but there are no link lights, and it will not recognize any connection. I am very disappointed in the quality of this card. It worked well at first, but it failed far too quickly. Consider this a warning if you plan to rely on it for more than a few months.

In case you don't want to read the full review the short version is: Good card, worth the money, fully recommended. The problem: The first picture shows the problem: a 1Gbps connection that only reaches just over 300Mbps, with a wired connection. Having checked every piece of equipment between modem and motherboard, including running a CAT 7 cable directly between the two the problem was finally identified as a dodgy Intel chipset on the ASUS B550-F motherboard. In other words the onboard LAN was just unable to deliver the full broadband speed - and had been delivering substandard speeds for some time. The solution: pictures 2-4: a NICGIGA 2.5Gbps PCI-E card with a Realtek chipset. Why this card? Well, simply put, it has a black backplate that fits in with the motherboard's black backplates. I know, not the best reason but it also has a known chipset, a decent heatsink on the main chip, an handle over the 1Gbps bandwidth, future-proofs to a certain extent and is at good price point. (A quick note about the future-proofing: a 1 Gigabit connection can potentially deliver over 1Gbps - up to 1.3Gbps - whereas a 1Gbps card stops at 1Gbps. This card is 2.5Gbps and so will handle over 1Gbps and provides some future-proofing for when the next major speed increase comes in.) Install: was really simple: unscrew a backplate, install the card, screw in the card, close the case and plug in a CAT 7 cable bought at the same time - KINBETA high speed 10Gbps 2 metre CAT 7 flat braided cable - and switch on PC. See pictures 6-8. The result: picture 9 shows the result. As soon as the PC started the card was recognised, no driver download was needed. The download speed jumped from 321.5Mbps to 925Mbps (picture 9) solving the problem in a most elegant way. It is interesting to note that the ping was 9ms both before and after upgrading the NIC and upload also remained the same - the 52Mbps which was the expected speed and initially highlighted the problem. For those with a small form factor PC it is worth noting that a smaller backplate is provided (see picture 5) as well as a screwdriver and two screws. Overall very happy with this purchase it solved the problem at a reasonable cost and I can feel the difference the higher speed connection makes. Definitely recommend this card.

Le produit est Bon. Pas hyper simple à installer pour ce qui concerne les Drivers sous Windows 11 mais en insistant, la carte est reconnue. Les débits sont conformes, jusqu'à 650Mo/s. Stabilité OK. Pas de dégradation après 1 an d'utilisation.

Instalar y utilizar. 0 problemas y tasa de transferencia sostenida.

This runs perfect in my pc. My internet connection is stable and runs at full speed. I even get the 2,5gbs intranet connexion from my router. My internet plan is only 100mbs so that doesn't benefit of the full 2.5gbs obviously but maybe in few years I'll get an optic fiber connection that will take advantage of that pciE card. This was easy to install and has no Cons or whatsoever.

Ich habe vor einigen Monaten das Tempo des Netzwerkes von 1 GB auf 10 GB erhöht, durch einen passenden Switch und ein NAS mit 10 GB Anschluss Da mein PC Onboard nur einen 1 GB LAN Port hatte, habe ich diese Dual Port Karte eingebaut. Der Einbau ging problemlos, ich habe jedoch auch keine große Grafikkarte verbaut. Es muss für Windows 11 noch ein extra Treiber herunter geladen werden, seit dem laufen die zwei zusätzlichen LAN Ports komplett ohne Probleme. Und der Datenduchsatz innerhalb des Netzwerkes ist ein riesengroßer Unterschied.
