The motherboard runs a Core i5-12400, which is a locked chip that tops out at 4.4 GHz, at 5 GHz with a base clock frequency of 125 MHz. This means that MSI will be adding BCLK overclocking capabilities to the B760 version of the Mortar Max.

MSI is one of the few motherboard manufacturers still putting external clock generators in Intel motherboards, especially in lower-end boards like the B series. 

BCLK overclocking changes the system's base frequency to generate higher core clocks as opposed to increasing the CPU core multiplier. It enables you to bypass Intel's artificial overclocking locks, and overclock any Intel CPU. The external clock generator is needed since Intel's default clock generator built into the chips is locked on non-K CPUs.

If the leak is true, this is MSI's second motherboard to date that features this exact same external clock generator, with the previous model being the B660M Mortar Max WiFi.
