The High-Efficiency Mode is designed to optimize memory performance byincreasing memory bandwidth and reducing latency. With the four sets of RAM timing settings, it allows users to find out the optimal configuration based on the quality of their memory modules.
Latency Killer
MSI BIOS has introduced the latest Latency Killer feature on all AM5 socket motherboards. Users can enable Latency Killer in the BIOS to reduce memory latency by up to 12% when running at high frequencies. Importantly, it is compatible with a wide range of memory overclocking features, including Memory Try It!!, EXPO, A-XMP, and High-Efficiency Mode, etc.
UP TO 12% Memory latency Reduction
*Supports BIOS versions after AGESA 1.2.0.2b.
- TVS
- SOLID PIN DESIGN
- STAINLESS STEEL IO
- OCP Protection
- GROUNDING STRUCTURE
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.
Anti-corrosive Stainless Steel IO Shield
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.
FROZR DESIGN
- FROZR GUARD
- FROZR SYNC
- FROZR CONTROL
- COMBO FAN
Combo Fan Header
The MSI Combo Fan Header is a versatile component, functioning as both a pump and or fan header. The header will automatically detects whether it is either pump or PWM/DC fan, with it's distinctive gray color ensuring easy identification
