Socket 1150 micro-ATX board

The GIGABYTE GA-H81M-S1 (rev. 2.1) is an Intel H81 micro-ATX motherboard built for the LGA 1150 platform. It accepts Core i7, i5, i3, Pentium and Celeron processors and provides two DDR3 slots for up to 16 GB of dual-channel memory. A single PCI Express x16 slot and two x1 slots handle graphics and add-in cards.

Passive chipset cooling

The H81 chipset runs without a fan so the board adds no active noise of its own. Power draw is limited to the CPU, memory and any installed expansion cards. Rear I/O includes two USB 3.0 ports, two USB 2.0 ports, PS/2 keyboard and mouse connectors and a D-Sub video output driven by the processor's integrated graphics.

Two SATA 6Gb/s ports

Storage connects through two SATA 6Gb/s headers while front-panel USB 3.0 and audio headers are available on the PCB. The Realtek ALC887 codec supports up to 7.1-channel audio when a compatible front-panel module is fitted. A single Gigabit LAN port provides wired networking at 1 Gbps.

Questions about this item

How do I install a CPU into the LGA 1150 socket without bending pins?

Lift the socket lever, align the processor triangle with the socket corner, place the CPU gently without force, lower the frame, then lock the lever back down; the lever tension secures the contacts.

What maintenance will the Realtek ALC887 audio codec need over time?

The codec itself is solid-state and needs no service; keep the rear 2/4/5.1/7.1-channel jacks dust-free and update the audio driver when Windows releases new builds.

At what point does the dual-channel DDR3 1600 memory subsystem hit its ceiling under sustained load?

The board caps at 16 GB across the two 240-pin slots, so once both slots are filled with 8 GB modules the memory capacity limit is reached.
