GIGABYTE B840M DS3H AM5 DDR5 Motherboard
Next-Generation Power and AMD AM5 Compatibility
The GIGABYTE B840M DS3H motherboard provides a responsive and versatile foundation for compact AMD desktop computers. Built around the AMD B840 chipset and advanced Socket AM5 platform, it supports compatible AMD Ryzen 9000, 8000 and 7000 Series processors. This broad CPU compatibility makes it suitable for modern gaming systems, content-creation workstations and productivity-focused PCs.
An 8+2+2 phase digital VRM power design provides stable and precise power delivery to the processor during gaming, content creation, multitasking and demanding computing workloads. Its space-efficient Micro ATX layout makes the board suitable for compact cases without sacrificing essential performance or expansion capabilities.
Four DDR5 DIMM slots support up to 256GB of dual-channel system memory. Compatible overclocked memory modules can reach speeds of up to DDR5 8200MT/s, depending on the installed processor, memory configuration and firmware support. This high memory bandwidth helps deliver responsive multitasking and faster performance across demanding applications.
High-Speed PCIe 4.0 Storage and 2.5GbE Networking
Two PCIe 4.0 M.2 connectors support compatible high-speed NVMe solid-state drives, helping reduce operating system start-up times, shorten game and application loading times and accelerate large file transfers. The dual-slot design also enables users to expand their NVMe storage without immediately replacing an existing drive.
Four SATA 6Gb/s ports provide additional connectivity for SATA SSDs and high-capacity hard drives. Support for RAID 0, RAID 1 and RAID 10 configurations offers greater flexibility for users who want to prioritise storage performance, data redundancy or a practical balance between both.
An integrated Realtek 2.5GbE LAN controller provides wired network speeds of up to 2.5Gbps when connected to compatible networking equipment. This increased bandwidth is ideal for competitive online gaming, high-resolution media streaming, network-based storage and transferring large creative project files with reduced waiting times.
Intelligent Thermal Management and Modern Expansion
Passive VRM cooling helps draw heat away from essential power-delivery components, supporting consistent operation during extended gaming sessions and processor-intensive workloads. This practical thermal design helps the motherboard maintain a stable operating environment inside compact and full-sized PC cases.
GIGABYTE Smart Fan 6 technology provides detailed cooling control through multiple CPU and system fan headers. Users can configure custom fan curves and monitor component temperatures to achieve their preferred balance between effective cooling and low-noise operation. Water-cooling pump support also provides added flexibility for compatible liquid-cooling configurations.
A PCIe 4.0 x16 slot supports compatible modern graphics cards for gaming, content creation and GPU-accelerated workloads. An additional PCIe 3.0 full-length expansion slot accommodates compatible auxiliary add-in cards, such as capture devices, sound cards and network adapters. These expansion options provide flexibility for future upgrades and specialised system configurations.
