Technical Summary

The Gigabyte GA-H61M-D2H revision 1.0 motherboard, documented on August 25, 2011, is built around the Intel LGA1155 CPU platform paired with the Intel H61 PCH. The board utilizes DDRIII memory across four DIMM slots, configured as one DIMM per channel on Channel A and Channel B. Graphics output is supported via RGB, DVI, and HDMI interfaces. The system incorporates a DUAL BIOS architecture for firmware redundancy. Key onboard controllers include the ITE 8728 EC/KBC, an ALC889 audio codec, an Atheros AR8151 Gigabit LAN IC, an Etron USB3.0 3232 hub controller, an ITE 8892E card reader, and a Marvell 9172 wireless module. Power management is handled by an ATX architecture with discrete voltage regulation provided by ISL95870 and three ISL6364 controllers. The board number is 9MH61MUB3-00-10B.
