[ COMPONENT RECORD // SYSTEM BOARD ]

Mother-
boards.

The motherboard connects the processor, memory, expansion cards, storage, power, and external I/O. The board's socket, chipset, firmware, and exact revision define compatibility.

SCHEMATIC // LAYOUT VARIES BY MODEL

CLASS RECORD: desktop system boards. For exact compatibility, use the board vendor's CPU list, memory QVL, manual, and support page for the printed model and revision.

Reference specifications

Common sizesATX 305 × 244 mm; microATX up to 244 × 244 mm; Mini-ITX 170 × 170 mm. Chassis and board documentation determine actual mounting support.
CPU interfaceSocketed processor interface, generation-specific. Same physical socket does not guarantee BIOS or chipset compatibility.
MemoryDDR type, slot count, supported capacity, speeds, ECC behavior, and validated configurations are board/CPU/firmware-specific.
Expansion & I/OPCI Express lanes/slots, M.2 sockets, SATA ports, USB generations, network/audio controllers, and front-panel headers vary widely.

Identification & compatibility

  • Record the exact model and board revision printed on the PCB; visually similar boards can use different firmware and connectors.
  • Check CPU support list and minimum BIOS version before installation. A board may require a supported older CPU or vendor flashback function to update.
  • Match RAM generation: DDR4 and DDR5 modules are mechanically and electrically incompatible.
  • Read the manual for M.2/SATA lane sharing, PCIe slot wiring, fan-header limits, memory population order, and clear-CMOS procedure.
  • Use ESD-safe handling, inspect for bent socket contacts and bulging/leaking capacitors, and do not power a board with loose conductive screws beneath it.

Often missed board components

BIOS/UEFI flash chips, embedded controllers, VRM stages, clock generators, TPM headers/modules, Wi-Fi antennas, backplanes, and riser boards are part of a complete system-board record.
