Technical Specifications
Technical Summary
The Gigabyte GA-H81M-DS2 Revision 3.0 motherboard, documented August 19, 2014, is built around the Intel LGA1150 CPU platform paired with the Intel H81 PCH. The board utilizes an ITE8620 LPC I/O controller for EC/KBC, HWM, fan control, and thermal sensor functions. Audio is handled by a Realtek ALC887 codec, while networking is provided by a Realtek RTL8111G LAN IC. The board supports DDRIII memory across two DIMM slots via a DDRIII BUS architecture. Graphics output is provided through an RGB Display interface driven by the integrated Intel LGA1150 GPU. Power regulation includes an ISL95812 VRIN PWM controller for VCORE and an RT8120 controller for DDR power. The board features a DUAL BIOS configuration and includes USB 3.0 hub support.
