It's maybe coming from new method of Intel Turbo Boost Max 3.0 all mates. Since Intel discovered that Intel Turbo Boost Max 3.0 app
cause some vulnerable to its CPU series here https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00243.html.
Intel and Microsoft agreement to bring its next revision of Intel Turbo Boost Max 3.0 app inside Windows OS kernel as service process.
When you use new Windows Version such as 1909 or 2004. It'll auto overclock to what Intel recommended speed of each CPU SKUs.
Just like my 7980XE will be automatic running at max turbo boost 2.0 and 3.0 ( 4.2GHz and 4.4GHz ) as picture belows.
The OS does it even we choose F5 Load Optimized Default via BIOS. I'd report to Microsoft last week. They'd fixing these
via lastest build 19628.1 today. They'll update to normal Windows soon. :cool:

I'm on 1909 18363.836 and when setting to optimized defaults my CPU never went above 4.0, so unless it's not in this build then I think there's something wrong.
Question for you though, when you go into services.msc do you see the intel turbo boost 3.0 service? Is it running. Additionally, in details of task manager, do you see itbmsys or in device manager the intel turbo boost 3.0 driver? In the other thread about removing the ITBM there are people recommending deleting the service, so I'm somewhat confused.
In other news, I played around with manual voltage a lot and noticed auto was applying way more than the required amount of voltage for any load, in one case a core was at 1.219 in auto with a ratio of 43, when on manual 1.115 (all core) I can get stable at a ratio of 44, provided I use avx offsets to low my avx ratio to 40.
EDIT: I'm actually in the insider program but had insider builds disabled, I've signed up so I can test newer builds but I'm out of time to test tonight.
since first BIOS rev. i enabled native Turbo Boost 3.0 in the BIOS and not Software.
Software sided TB 3.0 was always crap in last Gens
ASUS always set Voltage for 5.0GHz if you OC.
e.g you set allcore 4.7GHz the BIOS will enable the Voltage Table for 5.0GHz.
and thats waaaaaaaaay to much
So i need to reduce voltage up to -0.070 offset.
But i can't go lower, because with Cascade lake adaptive voltage will also decrease idle voltage
idle:
Default
Adaptive voltage -0.070
if i go lower bluescreen due to less voltage in lower Clock states
im actually not sure why ASUS dit that.
anyone can answer that?
I wish we could reduce Turbo Voltage and not just increasing 😕

This is the same situation I've found myself in, I want to lower my turbo voltage only, but using an offset makes me unstable at idle, can't even boot into windows with the offset it would need (it's like -0.105 to -0.200 or something).
I've settled for manual voltage for now because speed shift still doesn't seem to be as aggressive as it used to, if it's working at all, so it stays at max clocks most of the time anyway , guess I just eat the increased power at idle.
I'm planning on switching to the next gen ryzen when they come out and moving this cpu over to a server machine, with that on the horizon and all this weirdness I'm getting on this Asus board im having a hard time deciding what motherboard I'm going to go with.
