Z370 Micro ATX Board for 8th Gen Intel

The GIGABYTE Z370M D3H fits a Micro ATX chassis and accepts 8th generation Intel Core i7, i5 or i3 processors in the LGA 1151 socket. Four DDR4 DIMM slots support up to 64 GB of system memory. It is intended for compact desktop builds that need Z370 chipset features without a full-size ATX footprint. Builders who need more than four memory slots or a larger form factor should look elsewhere.

One SATA Cable and Rear I/O Shield Included

The open-box package supplies the motherboard, a single SATA cable and the chassis I/O back panel. No additional brackets, driver discs or Wi-Fi antennas are provided. The board itself exposes six SATA III ports and two M.2 interfaces for storage expansion. Users planning multiple SATA devices must source extra cables separately.

Aluminium Reinforcement on Primary PCIe Slot

The sole PCI Express x16 slot uses a metal-reinforced design to hold heavier graphics cards securely. Rear connectivity includes one USB Type-C port running at USB 3.1 Gen 1 speeds, six USB 3.1 Gen 1 Type-A ports and four USB 2.0 headers. Intel GbE LAN and Realtek ALC892 audio with 7.1-channel support handle networking and sound without add-in cards. The 24.4 cm square layout fits standard Micro ATX mounting points.

Questions about this item

Will the CMOS battery need replacing and is one included?

A metal battery is supplied with the board so the CMOS cell is already present and will only need changing when it eventually loses charge.

What caps the graphics throughput on the single full-size slot?

The board provides one PCI Express x16 slot running at x16 electrical, so the card itself sets the performance ceiling.

How loud and hot does the Z370 chipset get during all-day loads?

The chipset is passively cooled with no fan, so it adds no noise and its heat output stays within normal motherboard operating limits.
