MSI Readies 6.40 GHz OC Profile for Core i9-14900KS for Select Motherboards
 

Select MSI motherboards from the MPG and MEG series that support Intel's Extreme Power Profile, feature a UEFI Firmware setup program option called "P-core Beyond 6 GHz+." This is a set of overclocking presets by MSI, designed to work with select Intel KS-series processors. Apparently the BIOS MSI released to support the upcoming Core i9-14900KS, comes with this option along with several settings that can get two of the eight P-cores to boost to 6.40 GHz—200 MHz higher than Intel's maximum boost frequency for the chip.
