B365M HD3 Micro ATX DDR4 Board

This GIGABYTE motherboard uses the Intel B365 chipset on a Micro ATX form factor. It fits LGA 1151 socket processors such as Celeron Dual-Core CPUs. The board supports up to 32GB of DDR4 memory across two slots.

Entry Builders and Compact Upgraders

The board suits users assembling a budget office or home PC in a smaller chassis. Enthusiasts needing multi-GPU layouts or extensive overclocking headroom should look at full-size ATX alternatives with richer power delivery.

Dual-Channel 32GB DDR4 Limit

The maximum supported memory is 32GB of DDR4-SDRAM in a dual-channel configuration. This capacity ceiling decides whether the platform can handle your intended workload or if a board with four DIMM slots is required.
