GIGABYTE B840M D3HP
The GIGABYTE B840M D3HP motherboard is the fundamental building block for assembling a desktop PC and connecting all its hardware components. Featuring an AMD B840 chipset and an AM5 socket, this board supports AMD Ryzen 7000, 8000, and 9000 series processors. The device offers a stable foundation for the daily operation of your PC build in a compact Micro ATX format measuring 244×244mm. It uses a standard ATX power supply and a single 8-pin EPS connector for power. Integrated technologies efficiently manage power and monitor the temperature, voltage, and speed of connected fans. The board combines modern hardware standards on the AM5 platform and provides ample flexibility for future PC upgrades.

Processor and memory support
The board is compatible with AMD Ryzen 7000, 8000, and 9000 series processors. For system memory, there are four DDR5 DIMM slots with dual-channel support. Users can install up to 256GB of RAM with overclocked speeds of up to 8200MHz. The system automatically configures memory parameters thanks to its support for AMD EXPO profiles.
Storage devices and expansion slots
The board offers four SATA III connectors and two M.2 slots for installing hard drives and fast SSDs. The M.2 interface uses PCIe 4.0 for data transfer and supports 2280 and 2580 size drives. For graphics cards, it provides a full-throughput PCI Express 4.0 ×16 slot. You can place additional expansion cards in the PCI Express 3.0 ×1 slot.
Connectivity and rear panel ports
The rear panel provides various port types for connecting peripheral devices. Users can make use of USB 2.0, USB 3.2 Gen 1, and the fast USB 3.2 Gen 2 interface. You will also find a reversible USB-C port on the rear and internal headers for connecting to the front panel of the case. Network connectivity is handled by a classic RJ-45 ethernet port.
Graphics and audio outputs
For processors with integrated graphics, there are three video outputs available. Specifically, one HDMI 2.1 port and two DisplayPort 1.4 interfaces, which can handle high resolutions. Audio decoding is handled by an integrated Realtek ALC897 chip with support for 7.1-channel surround sound. The board includes analogue audio jacks for speakers and a microphone.
System features and cooling
The motherboard uses passive cooling for key components and offers headers for connecting case and CPU fans. Security features are represented by an integrated TPM header. Setup is managed through the UEFI AMI BIOS interface with 256Mbit of memory and a practical switch for clearing the CMOS memory. You can customise your case's appearance using the four RGB LED headers.
