4 Ports Gigabit M.2 M+B Key Ethernet Card SI-PEX24092

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.

worked GREAT with hardware passthru in a proxmox Ve system , i have been able to vurtualize my 2.5gbit routing

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.

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.

Linux plug and play. Works great on 6x kernels. 600MB/s to and from my TruNAS machine running four Hitachi 10TB platter drives in zraid. Performance is steady and stable.Truly happy this works because it's the only x1 card I could find. Most of my board is blocked off by my RTX4090 and brace. Only other exposed slot is x8 but it has a card with 4x m.2 nvme drives on it.EDIT 8/16/2025 The card lasted less than three weeks and died. Does not recognize that a cable is even plugged in. I bought two and the second is working in place of the failed nic. We will see how long that lasts.
