This article covers GIGABYTE B365 HD3 (LGA1151.

Overview

The GIGABYTE B365 HD3 is an ATX motherboard built around the Intel B365 chipset, supporting 8th and 9th generation Intel Core processors on the LGA1151 socket. Key features include dual M.2 slots, Realtek 8118 gaming LAN, and Smart Fan 5 for precise fan control. Positioned as a mid-range, cost-effective option, this board offers a solid foundation for reliable daily use or a budget gaming rig.
It supports DDR4 memory up to 2666 MHz in dual-channel mode, with a maximum capacity of 64 GB across two DIMM slots. The two M.2 slots accept both NVMe and SATA SSDs, giving you flexible storage options. The board also packs six SATA 6Gb/s ports and a mix of PCIe 3.0 slots, including a full x16 slot for your graphics card.

Compatibility Guide

  • Socket: LGA1151 (Intel 300-series chipset compatible)
  • CPU Support: Intel Core 8th Gen (Coffee Lake) and 9th Gen (Coffee Lake Refresh)
  • Memory: DDR4-2666/2400/2133, dual-channel, up to 64 GB (2 DIMMs)
  • Form Factor: ATX (305mm × 215mm)
  • Storage Interfaces: 6× SATA 6Gb/s, 1× M.2 Socket 1 (Key E for Wi-Fi), 1× M.2 Socket 3 (PCIe 3.0×4 + SATA)
  • Power Connectors: 24-pin ATX main, 8-pin ATX12V
  • Expansion Slots: 1× PCIe 3.0×16, 1× PCIe 3.0×4, 2× PCIe 3.0×1
  • Audio: Realtek ALC887 with high-quality audio capacitors
    A typical balanced build pairs this board with an Intel Core i5-9400F, 16 GB DDR4-2666, and a mid-range GPU like the GeForce RTX 3060. The B365 chipset is notable for retaining official Windows 7 support, which can be a decisive factor for some users.

Product Info

The GIGABYTE B365 HD3 launched in 2019 and currently sells for around ¥65,000 on Japanese online retailers as of September 2026. The warranty is the standard three years from the manufacturer. While the B365 chipset is older, it provides ample PCIe lanes for two M.2 drives and a capable GPU, making it a viable choice for builders on a budget who aren't chasing the latest platform. Market positioning: mid-range, value-oriented, with a focus on legacy compatibility and practical features.

Best Use Cases

  • Budget Gaming PC Builder: If you can score a used 8th or 9th gen Intel CPU cheaply, this motherboard lets you reuse DDR4 memory and add fast NVMe storage. It's a great pairing with an i5-9400F and an RX 6600 for 1080p gaming.
  • Legacy Windows 7 User: Professionals or enthusiasts who require Windows 7 for specific software will appreciate that B365 officially supports it. Newer chipsets often lack drivers, making this board a rare compatible option.
  • Versatile Storage Demands: With two M.2 slots and six SATA ports, this board is ideal for users who want multiple SSDs and HDDs without bottlenecking performance.
  • Who Should Look Elsewhere: Gamers needing PCIe 4.0 for the latest GPUs or SSDs, or those wanting to use Intel 12th/13th/14th gen CPUs, should skip this board and opt for a newer chipset.

Things to Consider

  • CPU Generation Limitation: Only 8th and 9th gen Intel CPUs are supported. Availability of these processors on the second-hand market is declining, and prices may be higher than expected.
  • Memory Speed Cap: Official support tops out at DDR4-2666. XMP profiles may not offer significant gains, so don't expect to run high-speed memory at its rated clocks.
  • No PCIe 4.0: Graphics cards and SSDs will run at PCIe 3.0 speeds, which for current-gen mid-range hardware is still adequate, but future high-end components may be bandwidth-limited.
  • Competition: In the same price bracket, B460 or H410 boards support newer CPUs but often have fewer M.2 slots or less robust audio. B365 HD3 is a strong choice if you specifically need dual M.2 and legacy OS support.

FAQ

Q: Does the board support CPU overclocking?
A: No. The B365 chipset does not allow overclocking unlocked CPUs (K-series). You would need a Z390 or Z370 board for that. However, memory overclocking via XMP is partially supported.
Q: Can I install a Wi-Fi card?
A: Yes. The M.2 Socket 1 (Key E) is designed for a wireless card. Intel CNVi-compatible modules (e.g., Intel 9560) work best. Alternatively, you can use a USB Wi-Fi adapter.
Q: Is a 500W power supply enough for this board?
A: It depends on the CPU and GPU. For an i5-9400F + RTX 3060 build, 500W is fine. For an i7-9700K + RTX 3070, we recommend at least 600W. Always account for your full system draw.
