Frequently Asked Questions
Description
The MSI B840M Gaming Plus WiFi6E sits in the mainstream tier of AMD's AM5 motherboard lineup, built around the B840 chipset in a compact mATX form factor. This white-themed board targets builders who want modern features without the premium price of X870 boards, supporting all current Ryzen 7000, 8000, and 9000 series processors. The inclusion of WiFi 6E wireless connectivity makes it particularly appealing for builds where ethernet isn't practical.
Memory support reaches up to 256GB of DDR5 across four DIMM slots, with speeds validated up to DDR5-8000 for enthusiasts who want to push performance. Two PCIe x16 slots provide flexibility for multi-GPU setups or additional expansion cards, while two M.2 slots both support PCIe 4.0 SSDs in the popular 2280 form factor. The board includes integrated RGB lighting headers and supports XMP memory profiles to automatically configure high-speed DDR5 kits.
Setup benefits from MSI's UEFI BIOS interface and standard motherboard accessories including the rear I/O shield. The board provides dedicated connectors for CPU cooling and water pump systems, making it suitable for both air and liquid cooling configurations. Four SATA III ports ensure compatibility with traditional storage drives, while the integrated WiFi 6E eliminates the need for separate wireless cards in most builds.
