IO CRESTM.2 M-Key PCI-e 3.0 Interface Single Port 5.0 Gigabit Ethernet Modules

Have not used it for extended periods of time, but seems to work correctly when combined with a USB4 or Thunderbolt4 port. It does get HOT, so don't put anything on top of it. Windows 11 driver worked just fine out of the box, but I did tweak some settings. I do this on all my Ethernet adapters.If your USB4 port is not also Thunderbolt, this device will not show up as a network adapter. It uses the Aquantia chip. It will show up as a USB device with no function.

Edit: as of XigmaNAS 13.1.0.5.9725 this adapter is now recognized and works as-expected! Thanks to ms49434 and zoon01 for applying a kernel patch to accept the PHY that is present. Original review follows.The adapter arrived in a small, cardboard box. The heatsink is attached securely. A hardware check indicates that the chip is revision 03.Under Windows 10/11, the adapter is usable with no additional effort or configuration on the user's side.Under Linux/FreeBSD, the adapter may or may not work depending on the version of the driver used to attempt init. Under FreeBSD specifically, support for the I225 was added in 13.1 via 𝚒𝚐𝚌, however the driver performs an unnecessary PHY vendor ID check, which may fail if the adapter reports an ID that isn't listed in an internal table.The fix (recommended by Intel themselves) is to no longer perform this check and instead assume a PHY for all I225 adapters. This fix is available in FreeBSD 13.2 and/or 14, and would need to be backported if using anything earlier.Examples; TrueNAS Scale 22.12.0 supports this adapter, while XigmaNAS 13.1.0.5.9687 (latest as of this review) includes 𝚒𝚐𝚌, but fails to init with the adapter I received.

This product does not support even basic PCIe power management technologies, such as PCIe ASPM L1. As such it can easily triple the power consumption of the computer it's installed in, by preventing the entire computer from entering lower sleep states.With this card installed my computer cannot go any lower than the C3 package cstate. Without the card installed it can stay in the C10 package cstate, which is the lowest power state.The chipset used in this card (ACQ113) can support PCIe ASPM L1 and the lower power PCIe L1.1 and L1.2 substates, but the card advertisers it cannot support them.As such this adapter is not functional for low power use cases. Suggest looking elsewhere if you need a low power 10 Gbps ethernet adapter.Firmware versions reported by the card in lspci:Bundle Version: 1.5.38Fw Version: 1.2.122Output of "lspci --vv" on Linux:Ethernet controller: Aquantia Corp.

Bought this to test with OPNSense. First time using it and setting up a router with my own hardware. I dropped this in an i7 4790, 16GB DDR3, 256GB NVME and this four port NIC. OPNSense detected without a problem and was up and running at 2.5gbps. I have a 2gig fiber connection and hasn’t given me any issues.I will note the card did not have a fan like the picture and does not have the option to add one. The heat sink is large enough that it shouldn’t be an issue but will tell with time. The model number received matches the pictures and one ordered so could be a different revision. I’m on the fence on returning this if heat is an issue since this is in an itx build with limited fans.Overall happy it with it.

This upgrade to 2.5gig Ethernet is easy to install into a PCIe slot and drivers are included on thesupplied mini CD. Many drivers are included including Windows 11, 10, Mac and Linux. Full speedis achieved using Cat 6 wire. Both full form and small form factor hardware included - easy to change out.Ethernet socket has two LED indicators for link and speed which is good since other cards may not havethese indicators or have holes to see through to an LED on the inside surface of the card. The Realtek chipand the software may be able to go to 10gig in the future since there is some references in drivers andother information of the system. Maybe a firmware update in the future for this?Overall, this is a great product and very reasonable in price and support.
