## Long description

Steel Legend is a motherboard series designed for durability and practical aesthetics, combining robust materials with mainstream features for daily users and enthusiasts. The board includes a 2oz copper PCB for improved thermal performance, support for DDR5 memory XMP and EXPO profiles, PCIe Gen5 Blazing M.2 for next-generation SSDs, an enlarged aluminium M.2 heatsink with anti-drop screw and a toolless M.2 installation mechanism, integrated Wi‑Fi 6E, Thunderbolt 4 Type‑C, 2.5 Gb/s LAN, and onboard RGB control compatible with Polychrome RGB and SignalRGB.
Advantages
The 2oz copper inner layers lower operating temperature and improve energy efficiency for overclocking. DDR5 XMP and AMD EXPO support make memory overclocking straightforward when using compatible modules. PCIe Gen5 Blazing M.2 doubles bandwidth compared to the previous generation to support ultrafast SSDs. Enlarged aluminium M.2 heatsinks, anti-drop screw and DIY-focused toolless design simplify installation and enhance thermal stability. Built‑in Wi‑Fi 6E, Thunderbolt 4 Type‑C and 2.5 Gb/s LAN provide modern connectivity options while onboard RGB headers and SignalRGB/Polychrome compatibility allow unified lighting control.

How to use
Install the motherboard in a compatible micro ATX case and mount an Intel Core Ultra Series 2 processor into the LGA1851 socket following standard CPU installation steps. Insert DDR5 memory modules into the DIMM slots and enable Intel® XMP or AMD EXPO profiles in BIOS if using supported modules to apply tested overclock settings. For NVMe storage, use the Blazing M.2 slot for PCIe Gen5 SSDs or the Hyper M.2 slots for Gen4 drives; the toolless M.2 heatsink and anti‑drop screw simplify M.2 installation. Connect storage devices to SATA ports as needed, attach power connectors from the PSU, and configure BIOS settings such as boot order, power management, and thermal monitoring. Use the onboard Wi‑Fi or Ethernet for network setup and connect displays via HDMI, DisplayPort or Thunderbolt 4 Type‑C. Control RGB lighting through Polychrome RGB or SignalRGB software after installing compatible LED devices to the onboard headers.
Рекомендации
Для стабильной работы и безопасного разгона используйте сертифицированные DDR5 модули с поддержкой Intel XMP или AMD EXPO, обеспечьте достаточную вентиляцию корпуса и при установке M.2 SSD воспользуйтесь прилагаемым большим радиатором и анти‑скользящим винтом.
