10Gtek 10GbE PCIE Network Card for Intel X520-DA1, 82599EN Chip, Single SFP+ Ports, 10Gbit PCI Express x8 LAN Adapter, 10Gb NIC for Windows Server/Linux/VMware

After a nightmare with Mellanox ConnectX 3 and HP NC552SFP+ cards either not working, incompatible or constantly crashing, I installed this Intel X-520 (82599) based card into my Win11 Gigabyte Z390 system. Finding drivers was a slight mission but once installed, this card worked like a champ. Tested with both DAC SFP+ and OM4 multimode fibre (Using a Mellanox SFP+ transceiver) and it ran consistently - no errors, no disconnections and excellent throughput. Tested with single / contiguous 120Gb files as well as folders containing 100Gb of small (3 & 4Mb) files, I got about 3.5 to 4.5Gbps consistent throughput. Was hoping for a bit more but will next be tweaking stuff like flow control, MTU, Jumbo frames etc. Disk IO is a bottleneck, even using EVO990 Pro NVME drives. I tested direct PC to PC connections using a DAC, then via switch (DAC on PC1, fibre on PC2) using the amazing Sodola 6 port 10Gbe managed switch sold here on Amazon for a ludicrously cheap £65 (as at Aug24). It was OK on crossover but really shone with the SFP switch. Highly recommend this card and really impressed with it. To be fair to Mellanox, their dual SFP+ card is excellent but it seems there's a major compatibility issue between Gigabyte boards (especially Z290/390/490 chipsets) and ConnectX cards. The only time it works is in a 16x PCIe slot. It will NOT work in an 8x slot due to lanes limited to 4. No way I'm dumping my RTX4070 so this 10GTek card came as a huge blessing.

Having been upgraded to Vodafone Full Fibre 910 service, I have been installing OM3 Fibre Optic cables in my house to get this amazing speed to the Windows 11 PCs in various rooms. The card was well packaged and installed easily onto my Aorus X670 motherboard. I also bought the 10Gtek SFP+ transceiver from Amazon to plug into the slot on this Network card. It all works amazingly well! I am now typically getting in excess of 900Mbps on my desktop using this 10Gtekcard. See screenshot. Fow the driver installation on Windows 11, there is a video on the Amazon page. It is not the easiest video to follow - the steps happen very quick - however the needed information is there. I used my video player stop button & rewind a lot to understand what to do. But do perservere - it is worth it!!! Since installation, connection is fast and stable. Very Please!!!

I bought this adapter a couple of years ago and haven't had to think about it since which is defintely a good thing. I seem to remember having a slight faff getting the driver installed on Windows 11 but, having done so, I inserted a 10Gtek optical transceiver I already had and connected my PC to my Zyxel 10Gb switch with a 10ft length of fibre. It runs cool and, being fanless, is absolutely silent. I have slightly better than 1Gb internet and I get full speeds all of the time. The reason I'm reviewing this now is because I'm thinking about replacing my NAS with a 10Gb-capable model and while reviewing my kit realised I hadn't done so. So, if you have a router or switch with an SFP+ port, this is a good choice if using optical modules. I'd steer clear of copper RJ45-style transceivers since, in my limted experience, these can run blisteringly hot so need to be actively cooled.

We known chipset. Compatible with various operating systems. Used with Win server, Win11, Linux and VMWare. All work reliably.

I use these in my Windows Servers and my Linux boxes. They run at full speed 10Gbps when coupled with NVMe drives in file servers.

It does exactly what it needs to do for a good price.

Got a couple of these installed in some Dell T5810 workstations. Used with Proxmox to hook up to my NAS for shared storage as well as various network VLANS. They work very well indeed. I replaced some old 10Gbe nics which were triggering overheat shutdowns. These are working perfectly so far. Recommended.

Tried multiple 10gtek modules (3 intel modules and 1 ubnt module), also tried a brand new LC cable and it just wont take the modules, they power up and then power down repeatedly, had to use a cisco DAC copper cable just to get it working. It was delivered in an open box too which made me wonder how many times it had probably fell out onto the floor, not a great experience. Will be returning.

I combined the 4 1Gb ports on my Synology 2419+ to get 4Gb throughout with an ubiquiti router. I have 12 10Tb disks in raid 5. The speed was a lousy 100Mb/s at best. Now I put this 10Gb X520-DA-1 card in the synology and connected it to an SFP+ port on my switch. Now I get a minimum and stable of 200Mb/s but I think thats the max of the disks combined. I'm very happy because an original card from Synology costs about 270€!!!!

Installed this 10Gtek PCIe network card on Windows 10 and it was up and running in minutes. No reliability or heating issues at all, which is important for my desktop. The card has stayed stable under load and overall has delivered just what I wanted for high-speed networking. Great value and dependable performance.

Fungerade direkt, körs i proxmox mot en Ubiquity Dreambox Pro och den kopplade upp snällt i 10 Gbit.

Nessun problema, rilevati perfettamente da Unraid e Linux. Non sono Intel originali ma il chipset è un ottimo oem cinese

Suite à l'arrivée de la fibre chez moi, j'ai décidé de déployer mon réseau local en fibre 10 Gbps pour profiter des 8 Gbps possibles avec ma box internet, j'ai donc choisi cette carte réseau pour mon pc de bureau. Installation : ✅ aucun souci, c'est une carte PCI-express tout à fait standard, qui prend peu de place Fonctionnement : ✅ fonctionne parfaitement et à la vitesse indiquée, à condition évidemment d'installer les bons pilotes. Débits atteints jusqu'à 6-7 Gbps, charge réseau de l'opérateur à prendre en compte, l'aspect limitant n'est probablement pas mon équipement réseau Problèmes : ✅ rien à signaler, pas de coupure intempestive etc. mis à part des problèmes imputables à l'opérateur ❗ Faire attention à la capacité des ports PCI-express de votre carte-mère, certains ne permettent pas le 10 Gbps et vous limiteront à moins (5 Gbps par exemple), ou ne le permettent que si vous ne branchez pas une autre carte PCI-express dans un autre port ou un SSD M2, tout devrait être indiqué dans le manuel de votre carte-mère
