Motherboard Layout Description
The motherboard features a standard ATX layout. Key components and connectors are strategically placed for accessibility and functionality. Prominent features include the LGA 1851 socket for the Intel® Core™ Ultra processor, multiple DDR5 UDIMM slots, several M.2 slots (M-key and A-key), and various PCIe expansion slots (PCIe x16, PCIe x4, PCI). The rear I/O panel includes display outputs (VGA, DP++, HDMI), LAN ports, USB ports, audio jacks, and serial ports. Internal headers provide connectivity for system fans, front panel audio, USB ports, SATA devices, and DIO (Digital I/O). The top view highlights the CPU socket, memory slots, and primary expansion slots.
Block Diagram Overview
The block diagram illustrates the internal architecture and connectivity. It shows the Intel® W880/Q870 chipset interfacing with the LGA 1851 CPU socket. Memory channels (Channel A and B) connect to DDR5 modules. Various I/O controllers manage interfaces such as 2.5GbE LAN ports, USB 3.2 Gen 2/Gen 1, USB 2.0, SATA 3.0, and serial ports (COM). Expansion capabilities are managed through multiple PCIe lanes (Gen 5 and Gen 4) connecting to the chipset and CPU, supporting graphics cards, NVMe SSDs, and other peripherals. Display outputs (VGA, DP++, HDMI) are integrated. Audio is handled by a Realtek ALC888S codec. Other critical components include SPI BIOS, TPM 2.0, and Super I/O for system monitoring and control.
Mechanical Dimensions
The motherboards adhere to the ATX form factor, measuring 305mm (12 inches) in width and 244mm (9.6 inches) in depth. The PCB thickness is 1.6mm. The top side height is 33.3mm, and the bottom side height is 4mm.
