Technical Specifications
Technical Summary
The Wistron OAK14 Chief River DIS (Document Number A31105, Revision A00, dated September 5, 2012) is an Intel Ivy Bridge platform motherboard with a BGA1023/BGA989 CPU socket and Intel Panther Point HM76 PCH. Graphics are handled by a switchable Nvidia N13P-GS or N13M-GS GPU supporting Optimus technology. The system firmware resides on an 8MB SPI Flash ROM. Embedded controller functions are managed by a Nuvoton NCT3940S-AN. Audio is provided by a Realtek ALC3221 HDA codec. Power management is handled by a BQ24727 charger IC and multiple DC/DC converters including TPS51216, TPS51225, ISL95833, ADP3211MNR2G, TPS51219, TPS51463, and SYW2311. Memory configuration supports two DDR3 1333/1600MHz SODIMM modules. The board integrates a Realtek RTS5170 card reader, a Realtek RTL8105E-VD 10/100 NIC, and a 802.11 b/g/n Bluetooth V4.0 combo Mini-Card wireless module. The PCB part number is 12204 with project codes 91.4WT01.001 and 91.4XP01.001.
Technician FAQ
Q: What is the BIOS flash configuration on this motherboard?
A: The motherboard uses an 8MB SPI Flash ROM connected via the LPC bus to the PCH.
Q: What EC/KBC controller is used on this motherboard?
A: The embedded controller is a Nuvoton NCT3940S-AN, communicating via the LPC bus.
Q: Does this motherboard support dGPU to UMA conversion?
A: The schematic indicates two configurations: UMA only installed and Discrete Optimus installed, suggesting the board supports both configurations.
Q: What is the charging architecture on this motherboard?
A: The charging circuit is built around a BQ24727 charger IC, with DCBATOUT as the main power rail feeding multiple DC/DC converters.
