Socket LGA 1151 B150 board

The GIGABYTE GA-B150M-HD3 is a micro-ATX motherboard built around the Intel B150 chipset. It accepts 6th- and 7th-generation Core i7, i5, i3, Pentium and Celeron processors in the LGA 1151 package. Two DIMM slots support DDR4 2133 memory up to 32 GB in dual-channel mode.

Builders needing legacy and modern ports

Six SATA 6 Gb/s connectors and one M.2 slot provide storage flexibility, while a full-size PCI Express x16 slot, two x1 slots and a conventional PCI slot cover both current and older add-in cards. Rear I/O supplies HDMI video, one PS/2 combo port, two USB 2.0 and three USB 3.0 connections. Buyers requiring more than two memory slots or multiple x16 slots should consider larger form-factor boards.

Two DIMM slots cap memory at 32 GB

The board offers only two DDR4 slots, so the 32 GB maximum is reached with a pair of 16 GB modules. If your workload demands four sticks or higher total capacity, this platform will not meet that requirement.

Questions about this item

Will the Realtek ALC887 audio codec or the two DDR4 2133 DIMM slots need replacement first?

The Realtek ALC887 codec is soldered to the board and not user-replaceable; the two DDR4 2133 DIMM slots accept standard modules that can be swapped if a stick fails or more capacity is needed.

Does the single PCI Express x16 slot running at x16 or the 32 GB memory ceiling limit sustained workloads first?

The board supports a maximum of 32 GB across its two DDR4 2133 slots, so memory capacity is the first hard limit for sustained workloads.

How hot or loud does the board get when the six SATA 6 Gb/s ports and the M.2 slot are active all day?

The chipset and voltage regulators are passively cooled; typical case airflow keeps temperatures in a safe range and adds no audible noise of their own.
