The PRO B840M-B is a business-oriented mATX motherboard constructed around the latest AMD B840 chipset which supports AMD Ryzen 9000 / 8000 / 7000 series desktop processors, featuring PCIe 4.0, 2.5G LAN, DDR5 and Frozr design that delivers the capacity to support a broad spectrum of both cutting-edge and innovative hardware.
The PRO B840M-B motherboard supports AMD Ryzen 9000 / 8000 / 7000 Series processors.
Form Factor: mATX
Socket Type: AM5
Chipset: AMD B840
With exclusive Core Boost technology and EZ OC Tuning functions, the PRO B840M-B is able to sustain heavy CPU power loads to support system-demanding settings:
Digital PWM IC
7-Phase direct CPU power (P-PAK)
2-Phase SOC Power
1-Phase MISC Power
Frozr Sync: Connect and synchronize cooling with strategically placed pin-headers - including CPU fan header (2A) and system fans(1A).
Frozr Control: Manage speeds and temperature for all fans of your system in MSI Center with Cooling Wizard and Frozr AI Cooling.
Memory Boost: A fully-isolated DDR circuit delivers pure data signals for optimal gaming and overclocking performance.
High-Efficiency Mode: Enabling High-Efficiency-Mode in the MSI BIOS increases memory bandwidth and reduces latency. Four different modes allow users to find out the optimal configuration based on the quality of their memory modules.
EXPO Profiles in the MSI BIOS are MSI OC LAB optimized and can be easily enabled with auto power settings for optimized memory speed and stability.
*1DPC 1R Max. overclocking frequency 8000+ MT/s, supports AMD EXPO.
MSI PCI Express Steel Armor slots are secured to the motherboard with extra solder points to support the weight of heavy graphics cards. When every advantage in games counts, Steel Armor also shields the point of contact from electromagnetic interference.
1 x PCIe 4.0/3.0 x16 slot (with Steel Armor and EZ PCIe Clip II)
1 x PCIe 3.0 x1 slot
The PRO B840M-B motherboard features MSI's M.2 slots:
2 x Gen4 x4 64Gbps slots
The DIY Friendly designs optimize the assemble process and experience.
EZ PCIe Clip II: Allows for easy removal of the graphics card by pressing the tail-like lock with one finger, even in the cramped case spaces.
EZ M.2 Clip II: Install or remove the SSD with a simple push of the latch, without using any screws.
2.5G LAN: A Realtek 2.5Gbps LAN controller delivers a premium network experience.
HD Audio: 7.1-Channel High Definition Audio with Audio Boost.
