Technical Specifications
Technical Summary
This Apple Computer Inc. motherboard, drawing number 051-6950, is designed around a 2.5GHz CPU platform with a 1.2V/800MHz core. The system architecture features an M56 GPU and an H8S/2116 EC/KBC. Memory is provided by two DDR2 DIMM slots operating in dual-channel 64-bit mode at 1.8V/667MHz. The BIOS is stored on an RMT BootROM SPI flash. Networking is handled by a Yukon Gigabit Ethernet controller and an Airport WLAN module. Audio processing is managed by an STA9221 codec. The board includes a U4800 Flash Controller for media card support. Power management is distributed across multiple ICs including U100 for charging and U8900, U8950, U9000, and U9050 for core voltage regulation. Thermal monitoring is provided by a U6100 GPU+NB temperature sensor and a U1000 CPU temperature sensor.
