Description
Gigabyte B840 Gaming X WiFi 6E Motherboard makes a strong first impression with modern connectivity and support for the latest AMD Socket AM5 processors.
This ATX motherboard is built around the AMD B840 chipset and is ready for AMD Ryzen 7000, 8000 and 9000 Series CPUs, offering a reliable platform for gaming and productivity systems. It uses Socket AM5 and supports UEFI AMI BIOS with a 256 Mbit BIOS memory for flexible system tuning.
Memory support is generous and future-proof, with four DIMM slots for DDR5-SDRAM in dual‑channel configuration and official speeds up to 7600 MHz. The board accepts up to 256 GB of unbuffered memory (up to 64 GB per slot), making it suitable for heavy multitasking, content creation, and gaming workloads.
Storage options include three M.2 slots (two PCIe 4.0 and one PCIe 3.0 supporting up to 25110 key sizes), plus four SATA III ports and room for up to seven drives in total. Hardware RAID 0/1/5/10 is supported for those who want redundancy or performance-oriented RAID arrays.
Expansion and cooling are well catered for, with three PCIe x16 Gen3 slots and one PCIe x16 Gen4 slot, multiple fan and water pump connectors (including two water pump headers), and passive cooling on critical areas. PC health monitoring covers fans, temperatures, voltages and water cooling to keep a stable system under load.
Connectivity is a highlight with integrated Wi‑Fi 6E (Realtek RTL8852CE) and Bluetooth 5.3, plus 2.5 Gigabit Ethernet (Realtek RTL8125). Rear I/O includes HDMI 2.1 and DisplayPort 1.4 for up to 4096 x 2160 output, numerous USB ports including USB‑C Gen2, and audio powered by the Realtek ALC897 codec supporting 7.1 channels.
The Gigabyte B840 Gaming X WiFi 6E is ideal for gamers building an AM5 system who want modern wireless networking, fast M.2 storage, and robust memory capacity. It also suits creators needing multiple high-capacity drives and a plentiful complement of headers for custom cooling and RGB lighting.
