Overview

The Gigabyte H370M DS3H is a Micro ATX motherboard built around the Intel H370 chipset. It uses an LGA1151 socket and provides four DDR4-2666 DIMM slots for up to 64GB of system memory. That combination makes it a natural fit for a budget-conscious gaming or general-purpose desktop build centered on Intel 8th Gen Core processors.
Positioned just above the entry level in Intel's 300-series lineup, the H370M DS3H trades away the overclocking tools of Z370 in exchange for a cleaner price and more practical feature set. You still get a PCIe 3.0 x16 slot, one M.2 slot for NVMe SSDs, and six SATA 6Gbps ports, so it is capable of handling a mainstream gaming rig or a reliable work-from-home machine. Its Micro ATX footprint also keeps the overall build compact and easier to manage in smaller cases.

Compatibility Guide

The CPU socket is LGA1151, and the primary supported family is Intel 8th Gen Core processors of the Coffee Lake generation. If you plan to use a 9th Gen Core CPU, check the BIOS version in advance because support depends on the installed firmware. Memory is standard DDR4 at up to DDR4-2666 speeds, spread across four slots with a 64GB ceiling.
The board uses the Micro ATX form factor, so it fits in most Micro ATX and full ATX cases. Expansion includes one PCIe 3.0 x16 slot for a graphics card and two PCIe 3.0 x1 slots. Storage connectivity is handled by a single M.2 slot and six SATA 6Gbps ports, which is enough for one NVMe system drive plus several SATA hard drives or SSDs. A standard ATX 24-pin main power connector and an 8-pin EPS connector are required. For a typical build with a discrete GPU, a 650W power supply is a sensible target.

Product Info

The Gigabyte H370M DS3H features the Intel H370 chipset, four DIMM slots, DDR4-2666 memory support, and a Micro ATX layout. It also includes PCIe 3.0 x16, PCIe 3.0 x1, M.2, six SATA ports, and gigabit Ethernet. On the rear panel you get HDMI, DVI-D, and VGA outputs, which makes multi-display setups possible with processors that have an integrated GPU. The onboard audio uses a Realtek ALC887 codec, adequate for headsets and desktop speakers.
As of September 2026, the reference street price listed at Yahoo! Shopping is 114,900 yen. That price reflects the scarcity of a discontinued platform rather than the board's original launch pricing. In the current market, this model is best treated as an entry-to-midrange motherboard for users who want a straightforward desktop build without premium overclocking features or next-generation PCIe support.

Best Use Cases

A first-time builder aiming for a 1080p gaming PC. Pair an 8th Gen Core i5 with a midrange graphics card and you have a balanced system that does not rely on overclocking. Users who prefer stable settings over maximum performance will appreciate the simplicity.
A builder who wants a compact Micro ATX desktop. Because the board is small, it fits nicely in mATX cases that save desk space without forcing you into ITX pricing. This works well for dorm rooms, small offices, and living-room PCs.
A user replacing an older desktop while reusing existing parts. DDR4 memory, M.2 SSDs, and SATA drives can often carry over to this platform, making the upgrade path cheaper and less wasteful.
An office or home PC that prioritizes low noise and reliability. Without overclocking support or a large number of high-bandwidth slots, the platform stays simple. That said, users who expect to run dual graphics cards or require native PCIe 5.0 should look elsewhere.

Things to Consider

The H370 chipset deliberately omits CPU overclocking, so buying an unlocked K-series processor for this board is largely wasted money. The platform also tops out at PCIe 3.0, which limits future expansion even though most mainstream graphics cards still operate well on that interface. The observed 114,900 yen price is likely inflated by low stock of an older-generation product, so check current listings carefully.
At that price, a newer entry-level CPU, motherboard, and memory bundle could deliver better overall value for a brand-new build. This board only has one M.2 slot as well, which matters if you intend to run multiple NVMe drives. For users who already own compatible parts, however, the H370M DS3H can still be a sensible building block.

FAQ

Q: Will any LGA1151 CPU work on this motherboard?
A: No. LGA1151 is used by multiple Intel generations, but the H370M DS3H targets 8th Gen Coffee Lake processors, with possible 9th Gen support depending on the BIOS. 6th and 7th Gen Skylake/Kaby Lake CPUs are not compatible.
Q: Can I install an NVMe SSD?
A: Yes. The M.2 slot supports PCIe NVMe drives, so you can use it as a high-speed system drive. Six SATA 6Gbps ports give you plenty of room for additional storage as well.
Q: Does this motherboard support overclocking?
A: No. The H370 chipset does not allow CPU overclocking. Memory XMP profiles may work, but this board is not the right choice if you plan to
