Technical Specifications
Technical Summary
This Quanta GM6C MLK DIS motherboard revision 1A, dated January 7, 2011, is built around the Intel Sandy Bridge processor (PGA 988) paired with the Intel Cougar Point PCH (mBGA 989). The platform supports three graphics configurations: Discrete Only (nVidia N12P-E/G), Optimus (SW), and UMA Only (HM67_UMA), with dGPU to UMA conversion facilitated by 0ohm resistors. System management is handled by an ITE8518 EC/KBC with a dedicated 512Kbyte flash, while the main BIOS resides on a 4Mbyte SPI flash. Memory architecture consists of dual-channel DDR3 800/1066/1333 1.5V across two SO-DIMM slots. The charging IC is an ISL88731, and power regulation is managed by a suite of ICs including TPS51427A, RT8207A, VT358, RT8015DGQW, NCP3218MNR, TPS51461, and NCP6131S. Audio is provided by an ALC665 codec with MAX9736AEJ+ amplifiers, networking by a Realtek RTL8111E-GR LAN, and connectivity includes a JMB389A card reader, UPD720200F1-DAK-A USB 3.0 hub, and SN75DP139RGZR/SN75DP120 HDMI level shifters. Thermal monitoring is performed by an EMC2112 sensor.
