Ok I actually found something, after about 2h of trial and error. If you go into regedit to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\
(look at the keys below, this is just a folder)
 
There you'll find a ton of invisible processor energy settings. Most of them are useless. There were 2 that did exactly what I wanted. I tried out each one and also compared the values to the "maximum" profile of Windows. 
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\36687f9e-e3a5-4dbf-b1dc-15eb381c6863 
@%SystemRoot%\system32\powrprof.dll,-812,Processor energy performance preference policy
 
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\6c2993b0-8f48-481f-bcc6-00dd2742aa06
@%SystemRoot%\system32\powrprof.dll,-701,Processor idle threshold scaling
 
(Set "Attribute" to "2" to be able to see these in advanced power settings dialog)
 
Processor idle threshold scaling is off at max performance profile, but on at all other profiles. So I turned it off at my profile to. 
Processor energy performance preference policy is set to 0% at max performance profile, 33% at balanced profile, 60% at aggressive power save profile. I set it to 20% and now my CPU is jumping nicely between 1Ghz idle and ~2.9Ghz under 40% CPU load - and it stays there pretty stable and doesn't flicker around. 
Of course don't forget to set "max cpu frequency also"..
 
Have fun and happy sunshine holidays
 

I'm on a laptop with i5-8250u - depending on the profiles I created, my CPU will throttle below 0.8 Ghz and Turbo up to 3.4Ghz. 
 
I already used a registry hack to get back the "Maximum Processor Frequency" setting in power options. But that's not what I want. 
 
I want to set a minimum frequency of 1.8Ghz. Google shows zero useful results. Whatever I try in power options seems to have no effect. Only when I clone the Windows Max Performance Setting I get to remove this super-low throttle but then my CPU is constantly high and battery is dry within an hour. 
 
Is there no way with this super expensive and sophisticated CPU to make it run between 1.8Ghz and 3.4Ghz? 
 
Yes, I really need that for productive purposes, not for gaming (got a desktop for gaming). This constant low throttle crap causes my applications to stutter and hang, Windows never seems to guess right how much CPU power it should deliver anyway. 

Many thanks.

I had 3 of these "smoking" within the first 3 weeks I had them. I'm talking about full-SoC Windows devices with soldered RAM, eMMC or NVMe, Ultrabooks / Tablets / Convertibles / 2-1 or however they call it.
 
1.) was a cheap one, don't remember the brand, from Amazon. The device, although new, arrived in a non-working condition and was sent back immediately. It was a 13" Ultrabook with an 7th gen m-whatever, 4GB of RAM and eMMC storage.
 
2.) I thought I should invest a bit more and bought the Acer Switch 3 Tablet, again a full-retar.. erm sorry SoC device with Apollo Lake N4200, pressure sensitive pen (had to purchase separately), 64GB eMMC, 4GB RAM, total cost ~500 USD. The device worked fine at first, I was pleased with the nice screen, the ability to paint on it, and that it was fan-less. That was until it started blue-screening, saying "SDBUS_INTERNAL_ERROR" more and more often until the third week I had it. Windows reinstall fixed nothing. Sent back to Amazon. Had to keep the accesoires.
 
(And also I had started to upgrade my Wifi to 5Ghz / Gigabit routers and a new NAS to compensate for the lack of storage)
 
3.) I thought, well maybe the last one still was cheap. So I paid about 8 times as much as I originally intended and bought an 8th-gen i7 intel tablet with 16GB of RAM, 1TB SSD, planing to keep the device for at least 5-10 years, maybe have the battery replaced at some point. The device smoked after a week.
 
I'm not aware that I did anything to make the devices break, didn't even bring them outside, didn't play Crysis, mostly Office and Web, didn't drop them.
 
Right now I'm pretty pissed. It's a lot of trouble going through sourcing the right device, ordering, installing, customer support, returning, feeling stupid, over and over again. These things seem to be as fragile as my love for Luke (no, just kidding, I will always love Luke).
 
Linus kinda covered this (for about 5 seconds) with the recent Razor Blade update, check the table at the beginning. So what is going on? I cannot find reliable stats on the internet. There's one generic Reuters article about Microsoft Surface more likely to break than other brands laptops. I really hope LMM would dig into Intel-SoC devices and see how likely they are to break. You got any numbers or specific device recommendations?
 
I'm probably spoiled, building my own PCs for almost 20 years, when a piece breaks, I replace that piece.
