245KF e-cores running full clock after update

[itidal]

yesterday, just installed the bios update that includes new core 200s on my msi pro z890-s mobo. unfortunately now my e-cores now run at maximum frequencies. Issue seems to be windows related, as I booted into a fedora liveusb (6.14 kernel) and frequencies seemed completely normal... windows task manager also seemingly can't monitor frequency correctly, showing 4,19 GHz static. (base clock of the cpu) any help is welcome. sorry if i posted this in the wrong section, i'm new in the forum and didn't find an processors forum, only the graphics cards.

Clear cmos.
Run defaults in windows. (Just to check stuff)
Windows Power mode set to balanced.
Use CPU-Z to view clocks. (Right click shows all cores on frequency or pick which core to display)
HWInfo64 for accurate readings.
Be sure management engine is up to date in windows. https://www.intel.com/content/www/u...ne-drivers-for-windows-10-and-windows-11.html

did everything still the same. (also these are hwinfo screenshots already)

Is that the newest bios with the S-boost feature? That is supposed to run when enabled OC D2D and NGU up to 3.2ghz.

Maybe look in bios and try disabling the S-Boost feature and see if this helps.

Does this impact anything ? Is the power consumption higher in idle ? The clocks which are reported don't necessary reflect reality.

s-boost on or off, it doesn't matter. dialing the d2d and dgu frequencies to 3.2 by hand also made no difference. my conclusion is probably something os-driver related got screwed up. i only had the chance to liveboot linux and from what i see, issue doesn't reoccur. i'll do a clean install of windows when i have chance to reorganize my file and such.

yes. cpu used to consume around 10 watts idle but now it's around 15-20w area, which is 50-100% more . nothing to be concerned about but it still makes me unconfortable.
