Unlocking high performance while maintaining low temperatures is the ultimate goal for gamers. MSI now introduces BIOS updates for Intel 700 and 600 series motherboards, supporting the ability to disable the CEP (Current Excursion Protection) function. This adjustment allows processors to operate at lower voltages and temperatures without compromising performance.
Disable the CEP Function
CEP, or Current Excursion Protection, is a function designed to prevent system instability caused by insufficient CPU voltage. However, the impact varies depending on the platform and combinations used, sometimes leading to a performance drop. Enthusiast gamers may choose to disable the CEP function to maximize performance. For more details on CEP functionality, please check our introduction article:
