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.

Fasssssssssssst lol even me silly as a sausage installed easy just took couple minutes to search the drivers 10 out of 10.

Installed this 10G Base-T PCI-e NIC (Marvell AQC1) in my workstation, and the performance has been excellent — consistent 9.7–9.9 Gbps transfers over CAT6a to my NAS. Drivers installed smoothly on Windows, with no compatibility issues. 🔗 Throughput: Low latency, stable speeds, and great performance with jumbo frames enabled. Easily handles large file transfers and real-time streaming. 🔥 Thermals: The one caveat — this card runs hot, especially in smaller cases or systems with limited airflow. Under sustained transfers, temps crept into the 80s°C. Adding a nearby fan or ensuring good case ventilation is strongly recommended. 🧩 Build Quality: Solid PCB, low-profile bracket included, and it fits well in standard x4 or x16 PCIe slots. ✅ Verdict: Excellent value for 10G networking, just be mindful of cooling. It’s a powerhouse NIC — as long as you don’t let it cook itself.

Bought a few different types of these two from mellanox which failed, decided to give old team blue a chance and it works great with Proxmox, I'm happy boy again.

Took two minutes to install and worked out of the box with Windows 11. It only needs a PCIe 1X slot of which I had plenty spare.

I purchased this NIC due to my Motherboard port dying. This was a great replacement and has resolved my issue. No issue with speeds as seen in screenshot.

These cards are plug'n'play under Debian Sid (6.11.2 kernel) and Bookworm (6.1.0 kernel) which use the atlantic kernel module, lspci identifies them as: 03:00.0 Ethernet controller: Aquantia Corp. AQtion AQC113 NBase-T/IEEE 802.3an Ethernet Controller [Antigua 10G] (rev 03) One of my machines sometimes get stuck at the grub prompt or reboots to the BIOS from a cold boot - moving it to the other PCIe 2 x8 slot seems to help a bit but not 100%, the other machine seems ok, as does a warm reboot. I initially used one with a TPLink 2.5Gbps switch where it worked at 2.5Gbps just fine, temps around 63c. iperf averaged about 2475Mbps in both directions. Moving to a NICGIGA 10Gbps switch they work at 10Gbps but does get a bit hot at up to 84c under load in one machine (the one with the boot issue) but seems to sit around 59c in the other at idle. iperf3 got up to about 9900Mbps between the two machines! Might just add a 40mm fan. Bit more expensive than 2nd hand SFP+, but they work in a multi-speed environment a lot better. Brilliant customer service too.

Installation facile ! Fonctionne très bien. À voir dans le temps.

works great! would recommend. i buyght this thinking it would work with my internet problem. but it didn’t. found out that my building is hiding a bad secret of coax cable in the walls and found out that every time i download big files crashes my internet on my desktop.. so this hole time i thot it was my motherboard 2.5g chip was going bad but it wasn’t

Funziona alla perfezione. Inizialmente non andava oltre i 2500 mbps. Poi disabilitando il risparmio energetico in win 11 (vedi foto), ho risolto e funziona alla grande. Con una 10gbps di dimensione, sto sempre a 8/2,5 gbps.

Questa scheda di rete PCI‑Express supporta connettività 10 Gb SFP+, montando un controller Intel 82599, spesso identificato come X520‑DA1. È ideale per chi ha bisogno di elevate prestazioni di rete in server, workstation o sistemi di archiviazione. - Punti di forza Controller Intel affidabile: il chip 82599/X520‑DA1 è molto apprezzato in ambito enterprise per stabilità e compatibilità. 10 Gb SFP+: offre alta velocità su infrastrutture in fibra ottica (tramite moduli SFP+ e cavi DAC). Compatibile con sistemi Linux/Windows: ampiamente supportata da driver open source (ixgbe) e firmware aggiornabili. Buon rapporto prezzo/prestazioni: considerando i modelli OEM rigenerati, offre capacità avanzate a costi contenuti. - Possibili criticità Driver e firmware: alcuni utenti riferiscono la necessità di aggiornare manualmente il firmware o i driver per ottenere prestazioni ottimali, soprattutto su Linux. Richiede una infrastruttura adeguata: senza cablaggio SFP+, switches o moduli compatibili, la scheda risulta inutile. Supporto ufficiale incerto: molti venditori offrono versioni ricondizionate o senza garanzia; è importante verificare dettagli sulle condizioni e supporto post-vendita. La scheda Intel 82599/X520‑DA1 è una scelta solida e conveniente se cerchi alte prestazioni di rete su hardware tradizionale. Offre stabilità, supporto driver ben collaudato e una buona velocità, pur necessitando attenzione al firmware, driver e all'infrastruttura compatibile.

Even my brand new motherboard for my latest build only had 5Gb onboard. I had recently rewired my house to Cat 6A and wanted to have a full 10Gb link between my NAS and my main computer. This fit the bill. Full speed over my home network and no issues whatsoever. I have not seen any drawbacks. Some complain about heat and connectivity issues, but I had none of that. The only time I had an issue was while I was installing Windows and it did not automatically have a driver available for this card. What I am saying is normally the Ethernet on the motherboard automatically has a driver for Windows installation. I had disabled the motherboard Ethernet and had to download a driver for this card prior to installing Windows. Not a big deal, just an added step that people should be aware of. Fit is not problem as it is a short card. I've not had any stability issues with this at all in the several months I've had it up and running.
