And since so much of Raptor Lake's performance comes from its high clocks, using a The comparator monitors the inductor feedback current against the peak current threshold. Applications with high thread counts, and/or “heavy” threads, can encounter PPT limits that can be alleviated with a raised PPT limit. What is it and should I be worried about that when I start overclocking. Go to Control Panel. At the bottom, you have several tabs, including Current, Creator Mode, Game Mode, Profile 1, Profile 2, and a few others. Everything seems fine apart from one thing. Not sure if this is a bad or good thing, but the common fix of changing power management settings to 'Balanced (recommended)' did nada. cpu did pull alot more wattage but system was unstable with those changes at 5ghz. There are some power supplies that are specifically designed to provide high peak currents. I changed the minimum power condition to 40% with reduced EDC to 25-40%.
