MSI PRO B860M-E mATX Motherboards ( Intel LGA 1851 Socket, Supports Intel Core Ultra Processors (Series 2) Cpu, 2x DDR5 RAM Slots, Max 128GB RAM Support )
- One Finger for EZ GPU Installation :- The new EZ PCIe Clip II, located on the first slot, features the rebounding force mechanism that allows for easy removal of the graphics card by pressing the tail-like lock with one finger. Due to this exquisite design, users can uninstall the graphics cards effortlessly, even in the cramped case spaces.
- ONE HAND :- MSI motherboards circuitry ensure the case standoff keep out zones are pure and clean. Moreover, the protective paint is printed around each screw hole to prevent parts from being scratched or damaged to the motherboard.
- EZ OVERCLOCKING :- While overclocking can be overly complex for some, MSI Click BIOS X made it more accessible with multiple one-click overclock features for both processor and memory, allowing users to easily enhance system performance without delving into intricate settings.
- EZ OPTIMIZATION :- A host of features inject artificial intelligence into key aspects of your computing experience to make smarter, real-time optimizations. The MSI Center offers a clean, minimal interface to customize and manage your PC settings. The AI Engine, for example, automatically adjusts settings based on the applications you’re using, ensuring seamless performance.
- Direct 6+1+1+1 POWER DESIGN :- Unleash and sustain the maximum performance with a flagship VRM design built with a total of 6+1+1+1 digital power phases. With an 8 pin power connector, PRO B860M-B is ready for the challenge of high-end processors.
- OPTIMIZED PCB SOLUTION :- The PCB design has been optimized for higher bandwidth and faster transfer speeds, which is also beneficial for reliable circuit transmission.
- 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.
- 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.
- STAINLESS STEEL IO :- 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.
