    As I was searching for adventure to keep squeezing more juice of speed of my laptop [See my sig.].. I was looking for something to do :D so it came to my mind about DPTF.. since it was disabled by default on my unlocked BIOS so.. I wanted to experiment it.. so what I did was enable it from BIOS and restarted & I got for like 13 drivers devices added on device manager [Previously it was only 1]

    Anyway.. I kept digging & looking through drivers files (.inf) and what does contains... it seemed to me that it missed adding power settings in able for DPTF to work fully so..

    I read & searched about something related to DPTF kept googling & found some info. on some russian forums & this [https://www.anandtech.com/show/9550...ower-and-thermal-framework-smarter-throttling] and this [https://superuser.com/questions/909...al-framework-settings-what-exactly-do-they-do):] after digging deep.. I finally found some registry keys that needed to be present in order DPTF to work fully functional. It doesn't add them when you setup or when you just install its drivers only so... I added those missing keys and after adding it those power settings showed so.. after choosing those settings through windows power settings....

    wow.. without even restarting.. it began to lower watts under heavy load or gaming..

    I made sure that it is not throttling or crippling something because I have got my fully speed all the time and under heavy load with lower watts! which means= lower temperature! ;) previously my cpu temp. was touching 80 c but now doesn't go over 73 c on all cores .. it is great :D

    Edit:-

    Oh yes.. I just found out now while writing this.. the reasons why I have have lower watts at the same full cpu speed is that it was playing with the CPU Cache speed.. it was lowering the CPU Cache speed when stressing my CPU so that it leads to lower watts = lower power consumption = lower heat. :)
    So.. it was a great journey for me.. although I don't see any performance degradation at all actually it improved :)

    For those who wants to have those power options.. make sure that you have all DPTF drivers installed bec. without them.. it doesn't have any effect no matter what settings you chose :)

    Note:- Open a Notepad & Copy it from the spoiler then save it as .reg file to work :) or download it from the attachemnt ;)

    No I still can't get into package C6 state. If you have some time try install Linux and check package c state there to determine if it's blocked by BIOS or Windows issue. I was doing some experiment today with MSI BIOS but no progress at all.

    Indeed. Extremely detailed guide, which I've followed as much as possible.

    I noticed that the CPU C0% for the first core spikes to ~50% whenever I move the cursor: it doesn't matter whether I use a USB mouse plugged into a USB-A port, plugged through an adaptor into a USB-C port, or while using the touchpad.

    Hi, thanks for posting that updated version! Please see https://imgur.com/a/9alWERM for all my settings, including two shots from the limit reasons. Interestingly enough - as you suspected - none of the boxes turn red when throttling...but one time the "vr thermal" box suddenly appeared. I completely shutdown and restarted, and it didn't appear the 2nd time. ¯\_(ツ)_/¯

    Also, here's the video I uploaded for Apple support. Note they of course required I reproduce in macOS...whatever! The crazy thing is after throttling occurs, it never seems to recover while the gpu is engaged despite ever-decreasing temps (the madness starts around 4:00): https://streamable.com/ea7jr

    So is it advisable to update TS(From 8.50 non-expire version to 8.70.6 by copying ini file) on broadwell based chips esp. 5220U?
    @unclewebb I think @kurtzyload might be partially correct on disk throttling not because its 70% full but temperatures above 70C will throttle the M.2 or custom Apple/Samsung NVMe/SATA drives. Maybe that is incorrectly signalling PCH to stop IO requests from/to SSD and inadvertently causing CPU to starve/throttle. Maybe I'm wrong! Apple always does what's best for consumer experience( Always!!!)
    Well DPTF is disabled by Dell on some models because it kills CPU. @Freitz has a issue when undervolting the cpu and WHEA when undervolted and he got replacement mobo which had zero issues.

    I know & I heard alot of horror stories related to DPTF but I'm sure that due to DPTF not functioning correctly which leads to problems & BSOD's alot.. I did alot of searching.. and always what I have found that people tend to only install the driver mostly & rarely others install through a setup from OEM websites I even saw people mod there BIOS to disable DPTF...but guess what....
    All of them doesn't have those power settings! They don't add those registry settings at all ! I'm sure it's the reason why DPTF was functioning like a crazy.. Shame on $hity Intel if they did that intentionally :(

    After I tweaked those power settings until now it didn't cause any kind of problems or any kind of stuttering or lag or even less performance... but what I did noticed is lower power consumption while on load or gaming without doing any kind throttle on CPU but it does indeed throttle the CPU Cache speed ;)

    I'm sure that those people who suffered alot of issues because of DPTF was not fully functioning... at the end DPTF goals was:-
    1) Lower temperature while maintaining high performance
    2) Lower power consumption which leads to lower temperature
    3) Longer battery life

    But all those goals was crippled by $hity Intel setups or drivers... I blame on Intel not DPTF :)

    AHCI, AHCI Link Power management HIPM/DIPM is set to Lowest

    I guess I can try a live version. Which program do you use to see it? What were your results in linux?

    Interesting thought re: SSD temp, and one I didn't consider! Unfortunately (or fortunately, depending on how you look at it), the SSD remains a frosty 40C when throttling occurs.

    Try searching my username on that guide's thread ( http://forum.notebookreview.com/thr...e-on-windows-enabling-deeper-c-states.815602/ ).

    I remember fighting with my deeper C states being on again off again for various reasons. Are you using an external monitor? Is your dGPU completely off? Those were two issues I think I remember discovering that prevented my C states from working correctly.

    NVMe SSD correct?
    Use HWINFO64 to see avg. temps when using CPU and GPU concurrently when playing a game or running simulations on OpenCL/Vulkan/Metal?
