I have an i9 - 9900k , Asus Maximus XI Hero , GTX 2080Ti . I replaced my TX950 Corsair PSU the other day with the Corsair HX1200 Platinum so i can buy another GTX2080Ti. I noticed my CPU was staying at 100% turbo frequency and i though it was because i was messing around with ASUS AI SUITE III.
Uninstalled ASUS AI SUITE III
Booted in Safe Mode
Reset Bios using CMOS button multiple times
XMP I , XMP II Clicked YES , Clicked NO to prompt , Set AI overclocker to AUTO
Used power saving plan for Power Settings ( Minimum CPU 5% )
Nothing seems to convince to make my i9 clock down. Sometimes , some cores go to 800 for half a second then to 2200 then back to 4800. My cpu usage is between 2-9% all the time.
Mention i am using the HX1200 Platinum in Single Rail mode. Could this be the issue ?
