10Gtek 1-Port 10Gb SFP+ PCI-E Network Card NIC, with Intel 82599EN Chip

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!!!

Using this as a 10Gb NIC on a Windows 11 PC. Once physically installed, the device is recognised by Windows. It works out of the box, but only at 1Gb. Download and install the drivers from 10Gtek's website, and it was offering 10Gb after the first reboot. Works well and good value for money.

Do not buy this for modern systems. It isn't a 10GTek card, it's 10GTek reselling a really old and outdated server NIC. Functionality When it works, it can work. But getting it to work on a modern UEFI system without CSM enabled means you have to flash a custom firmware edited by yourself to bring it up to standard. Otherwise on first boot it will hang the system. You'd have to remove it, go into bios, enable CSM etc then go into windows and flash the custom firmware. And even then on Windows 11, it causes all sorts of random issues like internet dropouts and kernal crashes. Speed No complaints, it can hit full speed. Value for money Given the hassle required to get it to work, i'd rather spend the extra £45 to get a proper modern ASUS branded SFP card. Ease of use Again, when it works, fine sure. But getting it to work isn't good for the average person (in fact the average person would probably just send it back.

I've got quite a basic PC but wanted to leverage the 10G capability of my network infrastructure, I had to change my graphics card to free up a PCI slot with enough lanes for this card. After installation (win10) it was recognised straight away, popped in my SFP+ module and I was good to go at 10Gbps! I'm getting transfer speeds of about 5Gbps when running an iperf3 test to my NAS which is great considering my limited hardware.

Really impressed with this 10Gtek 10GbE dual port NIC and it's working perfectly in Windows 10. I've installed a couple of 10Gbe SFP+ modules and connected via fiber patch leads to my network and have had absolutely 0 issues. The card is a PCI Express x8 card so make sure you have a suitable slot available to plug it into. For Intel based systems some of your slots may not be directly attached to your CPU and will be limited by your chipset. I've installed the card into an x16 slot which I know will have dedicated PCI lanes and offer the best performance. The card comes in a plain cardboard box with a driver DVD and small form factor back plate. I also highly recommend downloading and installing the latest Intel drivers to leverage the full capabilities of this card (such as VLANs and Teaming etc.)

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.

Easy to install. Debian pc installed the drivers automatically with no intervention required. Windows 11 found the card but could not automatically install a driver. I found in the end I had to download the full driver package from intel. Once I had done this windows installed the correct driver. No issues connected to a 10gb rj45 switch using cat 6.

Compatible with minisforum N5 base. Ran iperf3 successfully after making kernel tuning for Linux host and I get 10GB performance with both TCP and UDP flows. Cannot speak of other OS drivers as the main use case will be virtualization and Linux and so far it has been solid with a DAC CABLE

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€!!!!

I bought 4 of these to facilitate my 8Gb fiber connection. I've started noticing some huccups in my gaming, streaming, etc. I checked the Event Viewer on all 4 PCs and they all show a dropped connection multiple times since installation in December. I am on the latest driver and everything else is up to date on Windows 11. I replaced one with a Sabrent 10Gb NIC and it seems to be much more stable. Stay away from these things, they are outdated and troublesome.
