with Intel Chipset 82546 Dual Port Gigabit 8492MT PCI Server Network Card 1000M RJ45 NIC Ethernet Desktop Adapter

Works well and recognized. Only getting about 60-75% of max at least in my setup but awesome if need ports for older setup or PCI.

I was a little nervous about getting this card since the obvious "english as a second language" description made it seem like maybe it was but maybe it wasn't, but maybe it was running an intel chip and because of the reviews reporting non-intel chips. However, when I installed it in my truenas server to FINALLY replace the on-board garbage(realtek, yes, I should have read the section on compatible NICs when building the thing), the system booted right up and even presented the intel bios prompt for each chip/port on the card. I still wasn't 100% convinced so booted a live linux distro to see what the card actually reported for its chips. It's a dual card and both chips came up intel. Now that isn't to say they aren't couterfeit. China has proven it knows no boundaries when it comes to that, even going as far as hacking chips to present seemingly genuine identification/specs. I did do a sort of stress test after booting back into truenas by copying ~1tb of data and the transfer held steady at 103-105MB/s (big B for byte, not Mb/s for bit), which is satisfactorily close to the gigabit rating of my network. I also streamed on 2 devices at the same time from plex running on the server. It didn't drop once. The on-board garbage would regularly drop out with less than half that throughput. We'll see how it stands up over time though. Will update if anything changes. I'll also update if I ever get around to upgrading the rest of my network for higher speed and/or to handle aggregation so I can test that feature properly.

Dont know why people are expecting gigabit speeds from a 10/100 nic, says right at the top what it is. Building older machines, win98 me, xp, some older motherboards dont have onboard nic so this is the best option

While unlikely to be an issue for most home applications, a chinese network card is probably a no go for many places due to potential security concerns. I use it for my home server that host docker containers for media centers, HVAC, and some small home automation and web services, it's enough for me and I might consider putting it on a VLAN later. Works great with VMware ESX8

I bought this Ethernet PCI for replace My Ethernet at my Computer board. It work right out of the box. easy to install and compatible with Window's 10. the seller(Amazone) delivery on time as it promised. Thank.Minh Ngo

This is NOT a 64-bit PCI-X card, it is a 32-bit PCI card that will WORK in a PCI-X slot, but will then limit your PCI-X buss to legacy PCI buss speeds.Perfectly fine for a legacy PCI slot but will never reach full gigabit ethernet speeds even using just a single channel."COMPATIBLE" should be the headline for this product. PCI-X compatible. Gigabit ethernet compatible.I can't wait to find out how "compatible" the drivers are.

UPDATED:I'm an idiot. Card works. Both interfaces work. pfSense is plenty happy with it. Made some pretty rookie technical mistakes. Works with Debian bullseye too.Original review:I use this in my pfSense box, the drivers are happy with the chipset, and both interfaces are recognized. Interface 1 (igb0) is perfectly good. Interface 2 (igb1) doesn't detect a carrier. I've tried multiple cables, rebooting, and other troubleshooting steps. Link issues are one thing but it can't even tell there's a cable plugged in... I'll have to end up getting another card for my project.

I purchased and returned this network card because it never got close to full gigabit network speeds. Another gigabit card in the same computer transfers at the expected peak throughput of ~940 Mbps on my home network. This card would rarely exceed 600 Mbps, and usually averaged ~560 Mbps. I noticed after-the-fact that some positive reviews discussed similar speeds - I am assuming unaware that it was below par.I tested both ports and spent a half-hour with Amazon tech support. While being detected as a genuine chipset and passing various diagnostics, the card/chipset appears intentionally crippled imho
