Single Port 10 Gigabit Ethernet PCI-e x1 Network Card

インテルi225のB1とB2はバッグの製で1ギガモードでしか使えないだったけど、B3はやっと全部の問題解決されているので、買う意味ある。それでインテルのドライバーはやっぱりRealtekよりいい感じ。

当時のFreeBSDのバグで2022/09時点で最新のXigmaNASではI225-Vが動作しないようです。 dmesgではI225-Vとして認識されているようでしたが、次の行で 『Setup of Shared code failed, error -2』と出ていました。 現状最新版のFreeBSDでは改善されているようですが、XigmaNASの対応後に追記したいと思います。

IntelのI225が欲しくなったので購入してみましたが、(3)となっていたのでRev.3物の様です。 Z170-A、Z270F-GAMING、Z590-A GAMING WIFI(オンボ) いずれもI225-V Rev.3で揃えてみました。 余程怪しげな所から購入しなければ、Rev.3物になっている事でしょう。

Works well for what I needed it for

I bought this card as I wanted faster than the built in 1Gbs, but my Dell computer only has a single PCIe 3.0 x16 slot, which is occupied by a GPU, and an x1 slot. I know x1 slots have a maximum bandwidth of 8Gbs, so I wasn't expecting full 10Gbs speed out of it, but nonetheless iperf benchmarks are giving me a decent 7,5Gbs throughput. I note that other users have comment on heat. My PC has a decent case fan on the PCIe slots, so this has not been an issue to me, and it's maintaining around 47-49C under load. The card worked out of the box on Ubuntu 24.04 LTS and was easy to set up. Overall it's a decent card for the money, if your computer's PCIe slot availability limits your options.

The additional speed and compatibility with my ThinkCentre were very welcome, all file transfers etc have the hoped for boost. It seems to take 5-10 seconds to wake up and reconnect to the network after a sleep mode/ standby period with the PC, but that's long enough to make sure your tea is properly stirred.

This is working great in Unraid. Showed up as an interface as soon as I installed it. I have 1.5Gbps internet service and speed test is showing 1.6Gbps from Unraid server. Price was great for an Intel card and was shipped in 1 day.

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.
