Technical Summary

The Quanta Computer FM91A motherboard is an Intel platform designed for Auburndale or Clarksfield processors in an rPGA 989 socket, paired with a PCH. Graphics are handled by a discrete ATI M92-XT GPU (M92-S2-XT) via PCI Express. The system memory architecture consists of dual-channel DDR3 800/1067/1333 at 1.5V across two DDR3-SODIMM slots. The embedded controller is an ITE8502, and the audio codec is a 92HD73C. The BIOS/SPI flash is a 2Mbyte 17X8 device. Power management is handled by a suite of regulators including TPS51427A, TPS51116, TPS51218, ISL62882, MAX8792, RT9018, and RT9024, with an ISL88731 charging IC. Networking is provided by a Realtek RTL8111DL LAN controller, and the clock generator is an SLG8SP585V in a QFN-32 package. Thermal monitoring is managed by an SMS1422 sensor.
