Provides multiple categories that allow you to synchronise the applications you want to run, automatically optimising them to create a smoother computing experience.

AI LAN Manager

Optimises network performance and minimises latency, delivering a smooth and stable online experience.

Frozr AI Cooling

Automatically adjusts fan speeds to ensure the system remains cool, stable and operating at peak performance.

AI Boost

AI Boost is an MSI-exclusive feature that overclocks the NPU to deliver improved AI performance.

EZ DIY

EZ PCIe Release

An easy-to-access physical button release mechanism allows you to remove PCIe cards with a single press, making GPU upgrades and hardware changes much easier.

EZ M.2 Installation

Developed by MSI, this design allows SSD installation and removal without the need for screws, greatly improving convenience.

MSI’s EZ M.2 Shield Frozr II and EZ M.2 Clip II make M.2 installation simple. Insert the SSD into the slot and press it down to secure it with the clip. To remove the SSD, simply release the clip. The process is smooth and requires no tools.

EZ M.2 Clip Remover

MSI’s EZ M.2 Clip II Remover is a handy tool designed to reposition or remove the EZ M.2 Clip II on your motherboard. It allows users to easily detach the clip and reattach it to another M.2 slot if needed. The tool is included in the accessory kit provided with MSI motherboards.

EZ Button

Smart Button

A multifunction hardware button that can be configured in the BIOS. It can perform actions such as resetting the system, Safe Boot, Turbo Fan mode and EZ LED control with a single press.

Flash BIOS Button

Update the BIOS using only a connected power supply. A CPU and memory are not required.

Clear CMOS Button

Restore the BIOS to its default settings, which helps resolve most boot issues.

EZ Switch

Dual BIOS Switch

Allows you to instantly switch to the backup BIOS ROM if the primary BIOS becomes corrupted.

EZ LED Switch

Turn off all LEDs connected to the motherboard with a single press.

Metal Backplate

The metal backplate helps cool the MOSFETs using dedicated thermal pads while also strengthening the motherboard, protecting components and preventing PCB bending. This also makes installation easier.

Pre-Installed I/O Shield

The pre-installed I/O shield simplifies installation by removing the need to manually fit the shield during motherboard setup. Its integrated design ensures correct alignment and a secure fit while improving durability.

EZ Mounting

MSI motherboard circuitry ensures case standoff keep-out zones remain clear. Protective paint is also applied around each screw hole to help prevent scratches or damage during installation.

• Avoid Collision Notification
• Keep-Out Zone
• Double ESD Protection

EZ Antenna

The MSI EZ Antenna design allows the Wi-Fi antenna to be attached easily without twisting or rotating connectors.

Direct OC Jumper

The onboard dual 2-pin Direct OC Jumper enables simplified overclocking by allowing precise BCLK adjustments directly from the operating system. Additional BIOS options provide even more control over clock increments.
