It supports Jumbo Frames, Time Sensitive Networking standards, and intelligent load balancing for optimized performance on multi-core platforms. Designed for desktops and workstations with PCI-E slots, it offers plug-and-play installation and is backed by a 3-year warranty and lifetime customer support. ## Description This PCI Express controller with Base-T copper networking interface, provides compact, single-port integrated multi-gigabit (up to 2.5G) - MDI (Copper) standard IEEE 802.3 Ethernet interface for 2500BASE-T, 1000BASE-T, 100BASE-TX, 10BASE-TE connections (IEEE 802.3, 802.3u, 802.3ab). The Intelยฎ Ethernet Controller I225 is designed for use on any mobile, desktop, workstation, value-server, or industrial designs that have critical space constraints. Also supports the latest time sensitive networking (TSN) features, along with best in class power management and Operating System Support Review: Slow to connect from standby - 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. Review: 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 ๐š’๐š๐šŒ, 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 ๐š’๐š๐šŒ, but fails to init with the adapter I received. ## Features - The Intel Ethernet Connection I225 includes advanced interrupt-handling features to reduce CPU overhead. Other performance-enhancing features include offloading TCP/UDP (for both IPv4 and IPv6) checksum calculations and performing TCP segmentation. Other performance-enhancing features include offloading TCP/UDP (for both IPv4 and IPv6) checksum calculations and performing TCP segmentation. - Advanced features such as Jumbo Frame support for extra-large packets and Receive Side Scaling (RSS) are also supported. Additionally, I225 builds on prior controller solutions to add Time Sensitive Networking (TSN) features including IEEE 802.1Qbu, 802.3br, 802.1Qbv, 802.1AS-REV, 802.1p/Q, and 802.1Qav on select operating systems. These features support advanced time critical, and synchronized applications prevalent in audio/video, embedded, and industrial applications. - Advanced interrupt-handling features manage multiple interrupts simultaneously. Combining interrupt-handling features with intelligent filtering, ordering, and directing packets to specific queues and cores, enables load-balancing network traffic flows to improve throughput in multi-core platforms. - Other performance-enhancing features include IPv4 and IPv6 checksum offload, TCP/UDP checksum offload, extended Tx descriptors for more offload capabilities, up to 256 KB TCP segmentation (TSO v2), 40 KB packet buffer size, and 9.5 KB Jumbo Frame support. - What You Get: IO Crest 2.5 Gigabit PCI-E Network Card x1, Driver Disk x1, 8cm Low-profile Bracket x1. Backed by Syba 3 Year Hassle-free Warranty and Lifetime Customer Service. Important Note: Only work with PCI-E slot, Not for PCI Slot. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09SSD3HMB | | Best Sellers Rank | 113,231 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 416 in Network Cards | | Box Contents | 2.5 Gigabit Pci-e x4 Card | | Brand Name | IO Crest | | Color | Black | | Compatible Devices | Desktop | | Country of Origin | China | | Customer Reviews | 3.8 3.8 out of 5 stars (58) | | Data Link Protocol | Ethernet, Gigabit Ethernet | | Data Transfer Rate | 2.5 Gigabits Per Second | | EU Spare Part Availability Duration | 3 Years | | Hardware Interface | PCI Express x1 | | Item Weight | 0.18 Pounds | | Manufacturer | Syba | | Manufacturer Part Number | SY-PEX24076 | | Model Number | SY-PEX24076 | | UPC | 857426008895 | ## Product Details - **Brand:** IO Crest - **Colour:** Black - **Compatible devices:** Desktop - **Data link protocol:** Ethernet, Gigabit Ethernet - **Data transfer rate:** 2.5 Gigabits Per Second - **EU Spare Part Availability Duration:** 3 Years - **Hardware interface:** PCI Express x1 - **Item weight:** 0.18 Pounds - **Manufacturer:** Syba - **UPC:** 857426008895 ## Images ![2.5 Gigabit Ethernet PCI Express PCI-E Network Interface Card 10/100/1000/25000 Mbps RJ45 LAN Intel I225 Chipset - Image 1](https://m.media-amazon.com/images/I/51KzvHjN52L.jpg) ![2.5 Gigabit Ethernet PCI Express PCI-E Network Interface Card 10/100/1000/25000 Mbps RJ45 LAN Intel I225 Chipset - Image 2](https://m.media-amazon.com/images/I/71KwictQzeL.jpg) ![2.5 Gigabit Ethernet PCI Express PCI-E Network Interface Card 10/100/1000/25000 Mbps RJ45 LAN Intel I225 Chipset - Image 3](https://m.media-amazon.com/images/I/61w5hv-z5cL.jpg) ![2.5 Gigabit Ethernet PCI Express PCI-E Network Interface Card 10/100/1000/25000 Mbps RJ45 LAN Intel I225 Chipset - Image 4](https://m.media-amazon.com/images/I/61xx8rYXOhL.jpg) ![2.5 Gigabit Ethernet PCI Express PCI-E Network Interface Card 10/100/1000/25000 Mbps RJ45 LAN Intel I225 Chipset - Image 5](https://m.media-amazon.com/images/I/61SWvec-pEL.jpg) ## Customer Reviews ### โญโญโญโญ Slow to connect from standby *by R***K on 4 March 2024* The additional speed and compatibility with my ThinkCentre were very welcome, all file transfers etc have the hoped for boost.
