Technical Specifications
Technical Summary
The Compal DH53F M/B LA-F991P is a motherboard designed for the CoffeeLake H processor platform in a BGA1440 package, paired with a Cannonlake PCH-H chipset. Graphics are handled by an Nvidia N17E-G1 GPU with six gDDR5 memory chips. The system memory architecture is dual-channel DDR4, supporting 2400/2666 MHz modules across two 260-pin DDR4 SO-DIMM slots. The embedded controller is an ENE KB9022/9032, and audio is provided by a Realtek ALC255 codec. A single SPI ROM is used for BIOS storage. Networking is handled by a Realtek 8411H Gigabit LAN controller, and the card reader interface uses a Parade PS8527 re-driver.
