Gigabyte B840M D3HP WIFI6E — value AM5 Micro-ATX with Wi-Fi 6E
AMD B840 · Socket AM5DDR5 up to 8200 MT/s (OC)Wi-Fi 6E · GbEHDMI 2.1 + 2x DP 1.4
The Gigabyte B840M D3HP WIFI6E (part number B840M D3HP WF6E) is a Micro-ATX motherboard for AMD Socket AM5 on the B840 chipset, supporting Ryzen 9000, 8000 and 7000 processors — a value board for office, home and entry gaming PCs that need wireless networking.
It carries an 8+2+2 digital VRM on a 6-layer PCB, four DDR5 slots for up to 256GB (EXPO/XMP up to 8200 MT/s OC) and two CPU-attached PCIe 4.0 x4 M.2 slots, plus four SATA ports.
Rear connectivity includes Gigabit LAN, Wi-Fi 6E with Bluetooth 5.3, a 10 Gbps USB-A and USB-C, and HDMI 2.1 plus two DisplayPort 1.4 outputs for up to three monitors from Ryzen integrated graphics.
Compatibility note: LAN is 1 Gbps and the extra slot is a PCIe 3.0 x1. The B840 chipset does not allow CPU overclocking, and graphics and M.2 run at PCIe 4.0 rather than 5.0. Display outputs require a Ryzen CPU with integrated graphics.

Key Features
8+2+2 digital VRM
Digital PWM power with premium chokes and capacitors on a 6-layer PCB — stable for Ryzen 5 and Ryzen 7 processors at stock settings.
Two Gen4 M.2 from the CPU
M2A (2580/2280) and M2B (2280) both run PCIe 4.0 x4, with four SATA ports and NVMe RAID 0/1/5/10.
Wi-Fi 6E built in
MediaTek MT7902 Wi-Fi 6E with 160 MHz channels on 2.4/5/6 GHz, plus Bluetooth 5.3 for keyboards, mice and headsets.
Triple display outputs
HDMI 2.1 (4096x2160@60) and two DisplayPort 1.4 (3840x2160@144) — three screens without a graphics card on Ryzen iGPU models.

Frequently Asked Questions
What is the difference between the B840M D3HP WIFI6E and the B840M D3HP?
The WIFI6E version adds a MediaTek Wi-Fi 6E + Bluetooth 5.3 module and antenna connectors. Choose the plain D3HP if the PC will always use wired Ethernet.
How does it compare with the B840M GAMING PLUS WIFI6E?
They share the same B840 feature set, I/O and Wi-Fi 6E; the GAMING PLUS adds white heatsinks and gaming styling, while the D3HP keeps a plainer design at a lower price.
Can it drive three monitors?
Yes, with a Ryzen CPU that has integrated graphics: HDMI 2.1 plus two DisplayPort 1.4 support up to three displays at the same time.
Does it support Windows 10?
Yes, Gigabyte lists Windows 11 and Windows 10 64-bit support.
Singular Expert Insight
A no-frills AM5 board that covers what most office and home PCs need: Wi-Fi 6E, three display outputs and two fast M.2 slots. Gamers who want 2.5GbE should look at the GAMING X WIFI6E, and overclockers at B850. Add a DDR5 kit from our
DDR5 memory range.
✓ Buy it if you need an affordable AM5 Micro-ATX board with built-in Wi-Fi 6E for office, home or entry gaming use.
✕ Skip it if you want 2.5GbE, CPU overclocking or PCIe 5.0 storage.
→ Also consider the B840M D3HP without Wi-Fi if you use Ethernet only, or the B840M GAMING X WIFI6E for 2.5GbE.
