Intel Ethernet Controller I226-V
Single-port 2.5GbE controller IC for client motherboard and PCIe adapter designs. This is a controller/chip record; finished-card details are implementation-specific.
IDENTIFICATION: Match complete component top-mark, stepping and board revision. Nominal signaling rates are not measurements of application throughput.
Exact specifications and compatibility
| Dedicated subcategory | Ethernet controllers and PHYs |
|---|---|
| Exact controller identity | Intel Ethernet Controller I226-V |
| Component / board identity | Controller IC with integrated 2.5GBASE-T PHY; carrier board provides magnetics and RJ-45 connection. |
| PCIe bus and host interface | PCI Express 3.1 x1 host interface. |
| Ethernet ports / physical interface | One 10/100/1000/2500BASE-T port with auto-negotiation; actual link depends on board circuitry, peer port and twisted-pair cabling. |
| Nominal rate (not measured) | Up to 2.5 Gb/s nominal on one Ethernet link; not measured throughput. |
| Drivers and OS compatibility | Linux igc driver; Intel/OEM driver packages for supported Windows versions. Check exact stepping, platform BIOS/NVM, device ID and driver release; support differs among motherboard implementations. |
| Board / system compatibility | Requires an I226-V-compatible board or card with PCIe x1 routing, power, clock/reset, NVM and 2.5GBASE-T analog components. A bare IC is not a standalone PCIe card. |
| Revision and variant warning | I226-V is distinct from I225-V and the I226-IT variant. Identify the full suffix and stepping; firmware, platform design and board vendor support affect operation. |
| Measured throughput | No measured benchmark is claimed for a physical specimen. A valid result records the host, link partner, medium, driver/firmware, traffic pattern, test tool and duration. |

Archival and preservation notes
Record suffix and stepping, board model, device/subsystem ID and NVM version. Preserve original thermal pads/heatsink if fitted by the host design.
For an installed specimen, preserve source URL, access date, source revision and label/condition notes. Do not infer connector count or board-level compatibility from controller family name alone.
