Technical Specifications
Technical Summary
This Inventec VELLFIRE motherboard, project code CSA321-OCT-2002, is built on the Comet Lake-H platform. The system is powered by a BQ24780S charger IC and utilizes an ITE8987 EC/KBC. The dGPU power block includes an MP2886AGU controller, with GPU_EN indicating dGPU to UMA conversion support. Memory architecture consists of two DIMM slots (DIMM0 and DIMM1). The audio codec is an ALC255. The board includes a dedicated ROM1 for BIOS/SPI flash and an EC flash/ROM associated with the ITE8987E. Power management is handled by multiple ICs including NCP81215, NCP81151, NCP81253, SY8288CRAC, NB681GDP, NB685AG, APL3523A, APM514BA, SY8284CRAC, SY8088AACA, RT8097ALGE, RT8068AZQW, and RT8816A.
