Overview
The Gigabyte B365M DS3H is a Micro ATX motherboard built on the Intel B365 Express Chipset, designed to accommodate 8th and 9th Generation Intel Core processors in the LGA1151 socket — including Core i9, i7, i5, i3, Pentium, and Celeron variants. Its compact 22.6 cm x 20.5 cm footprint makes it well suited for space-conscious desktop builds without sacrificing connectivity or feature depth. Memory support spans four DDR4 DIMM slots capable of holding up to 64 GB of system RAM in a dual-channel configuration. Supported speeds include DDR4 2133, 2400, and 2666 MHz, with XMP profile support available on qualifying i5, i7, and i9 processors. Storage options are generous for this class of board. A single M.2 Socket 3 connector (M key, supporting 2242/2260/2280 form factors) handles both SATA and PCIe x4/x2 NVMe drives at up to 32 Gb/s, while six SATA 6Gb/s ports round out the storage array. RAID 0, 1, 5, and 10 configurations are supported through the chipset, and the board is Intel Optane Memory Ready. Connectivity on the rear panel includes four USB 3.1 Gen 1 ports, two USB 2.0 ports, a Gigabit Ethernet jack powered by a Realtek GbE LAN chip, three audio jacks, plus D-Sub, DVI-D, and HDMI display outputs for systems using integrated Intel HD Graphics. The HDMI port supports up to 4096x2160 at 30 Hz (HDMI 1.4) and HDCP 2.2. Up to three displays can be used simultaneously via integrated graphics. Audio is handled by a Realtek ALC887 codec delivering High Definition Audio in 2/4/5.1/7.1-channel configurations, with PCB-level audio noise isolation and high-quality onboard audio capacitors. A separate audio noise guard physically separates analog audio circuitry from digital noise on the board. System management features include Gigabyte Smart Fan 5, which monitors multiple thermal sensors and controls fan headers in either PWM or Voltage mode, with optional Fan Stop functionality to silence fans at low temperatures. RGB Fusion support provides a single RGB LED strip header compatible with 7-colour LED strips. The BIOS uses a dual-chip AMI UEFI DualBIOS design — two 128 Mbit flash chips — providing an automatic fallback if the primary BIOS is corrupted. Software support includes the Gigabyte APP Center suite with tools such as EasyTune, RGB Fusion, Smart Backup, Game Boost, and Q-Flash.
