Gigabit Dual NIC with Intel 82576 Chip, 1Gb Network Card Compare to Intel E1G42ET NIC, 2 RJ45 Ports, PCI Express 2.1 X1, Ethernet Card with Low Profile for Windows/Windows Server/Linux

I'm using a pair of these Gigabit Dual NIC with Intel 82576 Chip on OpenBSD. Worked OOB. It's been running for about a month now. I've had no trouble getting ~1gbps saturation on these cards between machines tested with iperf or through the internet with various speed test sites.

Works great.. no problems..

Plug and play! No firmware updates needed and running in both ports in aggregate connected to a Unifi system.

Our Dell XPS 8930 at church that we use for streaming has the Intel "killer" ethernet E2500 chipset in it. Worked good for a long time, but then all of the sudden it would start dropping out during a service. It would disconnect for a few seconds, then reconnect. It would do it quite often. Tried updating the drivers and trying other tweaks found with net searches but no luck.We switched to wifi but that was causing issues too, the video would stutter or freeze from time to time. Probably because too many devices were connected to it?So decided to try add-on card in the computer. The X4 slot was being used for a video capture card and the X16 for a video card. It has 2 X1 slots but I think the video card covers one of them.After the fiasco with the E2500 was hesitant to go Intel again but the I210 chipset gets good reviews so got this one. Thankfully was able to squeeze this into the open X1 slot and so far so good, our streaming connection appears to be solid now and speedtest is reporting 200/200 which is what our internet service is. Even changed the settings in OBS to get a better picture and it handled it like a champ.

1 Gbe is pretty slow these days but being an intel NIC it has wide compatibility so you don't run into some of the issues you can run into with other brands like realtek on FreeBSD.Great replacement for a SuperMicro server whose NIC died on me recently.

I was trying to install VMware ESXi 7 on an old Dell XPS desktop system, but ESXi would not recognize the built-in NIC, and thererfore wouldn't complete the installation. After multiple failed attmpts to follow online and YouTube instructions on how to "inject" NIC drivers into the ESXi ISO, I gave up and decided to try a new card.I purchased the "Gigabit PCIe NIC with Intel 82574L Chip" since this chipset is actually listed in the VMware Hardware Compatibility Guide, and the Amazon description claimed it to be ESXi 7 compatible. I was pleasantly surprised that the card was identified by ESXi, and the installation completed without any problems.I can't speak about whether the other NICs on this Amazon page would work with ESXi 7, mainly because the descriptions for some of the cards do not explicitly mention being ESXi compatible. But I can definitely recommend the one with the 82574L chipset based on my success... plus the price is right!

Machine goes into power cycling and will not post with this card installed. Motherboard is a Gigabyte X299 Aorus Master. Without this card it operates properly. Sad that there is such a short return window for a non-working product.

Fast and absolutely compatible with my older motherboards.
