HP | 614203-B21 | NC552SFP | 10Gb 2-port PCI Express x8 Ethernet Server Adapter

It's insane what you can get for $50. A dual port SFP+ NIC. This NIC works right out of the box in my Unraid server and does LACP nicely. Works with any 10 gigabit transceiver, both copper and fiber. No need to spend $200 on an Intel dual port SFP+ NIC, unless you really want the Intel management software and an outdated driver CD. In fact, you can buy a pair of these NICs and it's still cheaper than a new Intel NIC.Of course the green PCB is an eye sore if I were to install this in my own pc, but you don't care about aesthetics as much as I do in my PC, then this is the NIC to get.

used to work on my old desktop but it is not compatible with motherboard z 490 and newer

This NIC works well in most systems, but does not work in all. I tried using this on an ASUS PRIME Z590M-Plus motherboard, for example, and it will not POST with this card in either of the two PCIe x16 slots. Even using the "tape-over-the-SMBus-pins hack" that is used for some server grade HBAs to make them work on desktop motherboards, having this card in the system will not let it POST. It does however work on my AMD Ryzen based systems using the B450 or Z570 chipsets from Gigabyte and MSI without having to use any "hacks" to get it to work. I was able to use a different server grade dual port 10Gbit NIC on the ASUS Intel board that worked fine without any "hacks". I'm not sure if this is an Intel issue (I don't have another modern Intel motherboard to test with) or just a motherboard specific issue.

Installed this in a small form factor, home built NAS running windows server standard 2019. Windows recognized with no problem running fast as expected! Kudos to seller TechnoDealsUSA, item came with a low profile bracket (delivered 15 days before expected delivery). I sent an email to the seller requesting a full height bracket and received it a few days later via FedEx. I am very happy with the product and seller!

So you just shut down, plug in, and this will work on a Windows 10 computer. The first boot or two take five to ten minutes, which is really scary. But once it finally boots up, all the drivers are installed, and the cards work properly.

My motherboard did not support this card. I ended up getting another card that was pci-e instead.Do keep in mind if you are new to this you can’t have more than one nic adapter unless you control this at the switch level. Also it’s not recommended or really supported to have more than 1 nic in the same subnet. I highly recommended to disabled the built in nic on the motherboard. Use fiber or Ethernet injection for HP if you can find them (don’t cheap out). While the Cisco ones may work it’s best to find the proper injectors or fiber adapter.Recommended for those looking to have more speed. This can be configured for 2 10gE uplink. While I did not end up using got my server I did confirm the card works just fine and probably the cheapest name brand you can find.

The first issue I had with this device was that it still runs on PCIe 2.0. I accept the part of the knave for not having looked at that specification beforehand, but it didn't seem to play well on more modern motherboards.The other issue is that it died. That's right, just a few months of almost never using this (no really, I had set it aside in a machine I was building) and it died. I wish I could say money well spent, but that would imply that I didn't spend about 60 dollars for a piece of technology that I hardly ever used that broke when I finally went to put it to use.My advice: go with something a little higher up. They're almost all more expensive, but on the plus side, you'll be far less likely to have what happened to me happen to you. Good luck.

Running with no issues on AsRock X570 Mobo with Ryzen 9 5950x with ESXi 6.7 U3 hypervisor . Full speeed 10G!Next is to add a card to older intel sky lake server being upgraded mobos…
