DDR5 MEMORY SUPPORT WITH HIGH PERFORMANCE
A huge step of DDR performance enhancement with the latest DDR5 memory. Combines with dedicated SMT welding process and MSI Memory Boost technology, PRO B860M-B is ready to deliver the world-class memory performance.

Memory Extension Mode
Memory Extension Mode provides optimized memory parameters for enhanced capability at the same frequency, achieving lower latency and higher performance. Furthermore, Memory Extension Mode can combine XMP profiles to maximize memory frequency, enabling users to effortlessly discover the best configuration based on their requirements.

Performance Mode, Benchmark Mode, and Memtest Mode provide users with the flexibility to swiftly identify the ideal configuration tailored to their requirements and memory overclocking capabilities.
Transient Voltage Suppressors (TVS)
Transient Voltage Suppressors (TVS) are safety devices used to protect against excessive voltage. All motherboard models of MSI are equipped with TVS. When the voltage abnormally rises, the TVS switches from a high-resistance state to a low-resistance state, diverting the excessive voltage to ground. This helps prevent circuit damage caused by high voltage.
solid pin design
The 8-pin, and 24-pin power connectors of MSI motherboards are all designed with solid pins. The solid pin design allows for a more stable transmission of 12V power to the CPU, even when handling high current loads.
Advantages of Solid Pin Power connector
- Improved stability : Larger contact area enhances stability during power delivery.
- Low impedance : Solid pins offer low impedance, enabling efficient power flow.
- Strong durability : The solid pin design ensures strong durability, capable of withstanding demanding conditions.
- Suitable for high-current applications.

An extra layer of sponge materials along with corrosive resistance IO Shield to help improve static electricity and reduce electromagnetic radiation noise from the system as well as much more durable compare to traditional IO Shields.
Over Current Protection
MSI motherboards prioritize safety with the embedded Overcurrent Protection (OCP), ensuring crucial components such as the USB ports, DDR memory, PWM IC, and CPU are shielded from excessive current. This proactive defense mechanism curtails the risk of damage or malfunction due to power surges, promoting long-term system stability. This commitment to safeguarding your hardware underscores MSI’s dedication to producing motherboards that prioritize durability and stability.



The Grounding Structure of Power Phases
The grounding structure of power phases is the MSI’s exclusive design. This patented design enables to suppress the electromagnetic interference (EMI) generated by the power phases and helps to efficiently conduct heat to the copper plane with grounding properties.
