H!Fiber 10Gb SFP+ PCI-E Network Card NIC, with Intel 82599ES Chip, Dual SFP+ Ports, Compare to Intel X520-DA2 (E10G42BTDA), PCIe X8, Ethernet LAN Network Adapter Support Windows/Linux/VMware

Windows 10, it worked out of the box. To get it to work on Linux, it took me a little long as it detected the card and showed the interfaces, but I had to dig through the startup log (dmesg) in order to find out that the drivers were not loading. Downloaded the drivers, installed them, and POOF! Working in Linux, too! I don't foresee myself needing to add anymore 10G NICs to any more of my devices, I would definitely consider re-ordering these. iperf3 results [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 1.06 GBytes 9.09 Gbits/sec 53 1.76 MBytes [ 5] 1.00-2.00 sec 1.09 GBytes 9.38 Gbits/sec 9 2.02 MBytes [ 5] 2.00-3.00 sec 1.09 GBytes 9.41 Gbits/sec 32 2.01 MBytes [ 5] 3.00-4.00 sec 1.09 GBytes 9.38 Gbits/sec 2 2.01 MBytes [ 5] 4.00-5.00 sec 1.11 GBytes 9.57 Gbits/sec 44 2.04 MBytes [ 5] 5.00-6.00 sec 1010 MBytes 8.48 Gbits/sec 153 1.99 MBytes [ 5] 6.00-7.00 sec 966 MBytes 8.11 Gbits/sec 131 2.01 MBytes [ 5] 7.00-8.00 sec 1.04 GBytes 8.97 Gbits/sec 15 2.01 MBytes [ 5] 8.00-9.00 sec 1.12 GBytes 9.59 Gbits/sec 66 2.02 MBytes [ 5] 9.00-10.00 sec 1.03 GBytes 8.81 Gbits/sec 163 2.03 MBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 10.6 GBytes 9.08 Gbits/sec 668 sender [ 5] 0.00-10.00 sec 10.6 GBytes 9.08 Gbits/sec receiver As you can see, there is some variation in the speeds, but seeing that this server is now live (I should have saved iperf results before I turned this server loose), but for the most part, I am getting 9+ Gbits per second. Damn impressive.

Me costó instalarlo en Windows 11 pero lo logré, hay que seguir las instrucciones, excelente producto

Works just as expected, added to my OPNsense box to transfer my LAN switch to a 10gb connection with a patch cable. Has been running without fail since installing

I just can't find the Driver for the H!Fiber 10Gb SFP+ PCI-E Network Card. If anyone out there has this driver that works

This is the second one I have purchased. It is a backup in case the one I currently have goes bad. I use this in my pfsense machine I build from an old HP SFF desktop. It's extremely stable and very fast throughput. I have used it in windows as well and the driver support is plug and play. I have never had an issue with it and love having dual connectivity as I use it to support multiple VLANS. This helps me maximize my home network. Very good value for the money.

It sends all my data overseas, but my network go brrrrrrrrr, so cool.

Solido como una roca

I installed this card in my older HP Z440 running Proxmox, and it worked flawlessly from the moment I plugged it in. With its renowned Intel chipset, this card is incredibly stable and effortlessly achieves the maximum throughput through the SFP+ connector without any stability or cooling issues. Considering its affordable price, it’s a well-worthwhile investment.

Worked great but then died after 16 months of use.
