    @henk-dev I think it just must be the differences in bios. I can happily hold 2.3Ghz all 4 cores and 700Mhz GPU now thank’s to you with furmark and CPU test the thermals max are always under 75 degrees which is great. I have a huge thermal pad on top of the copper heatsink. Before my GPU would lower to 450Mhz.

    My bios completely different: NB-118-B and dated 07/16/2019 the website doesn’t list a new version to flash. So this is our difference I think and why the difference in wattage. You must have something tweaked in the bios or higher current limit or something.

    Hi guys

    Its my first post here and I wanted to thank Chris, Henk and the others here in this forum for their valuable help.

    Now after reading all the posts I can run my Alldocube Knote x pro (n4100) at 15 watts using these settings:

    W16 0xFED170A8 0000
    W16 0xFED170AC 0000

    WRMSR 0x610 0x0 0x00DD8F00 0

    My cpu speeds are maxed but gpu seems stubborn and cant go over 450 Mhz.

    Is there anyone with the same tablet that achieved higher gpu speeds?

    @georgo85 You should get 700Mhz max, but if you don’t it might be your thermals restricting you.

    Hi Chris

    I haven’t seen the max gpu going over 450 even for a second and also according to throttlestop the limit is pl1 and some times edp current. Maybe if I tweek a bit the DPTF settings in bios.🤞🤞

    EDIT: No luck after disabling DPTF

    PS. Thermals are OK compared to knote 8 with the m3 core!!

    I had issues running the complete unlock via batch file or on boot. My way around it was to open RWeverything and then insert the commands and hit enter. Get the confirmation it worked and then I got 700Mhz and 2.3Ghz overall 4 cores.  Couldn’t quite get what Henk had for pulling 15W.

    Sooo after a lot of research (I really like max Mhz in my gpu :P) I found that actually the intel graphics plan in power options doesn’t affect the gpu clocks at all, as you can see in screenshots.

    It seems that it is stuck at balanced at all times at 450 Mhz max not even a little spike at 700Mhz. I tried change it with Control Panel for Intel Graphics, I updated the graphics drivers and uninstalled TPDF. Can this be a bios thing? I also disabled c states and  TPDF from there and everything seems at maximum performance. I even reset the tablet but no luck.

    Has anyone encountered a similar problem? Thanks again for your time 🙂

    @georgo85 I read that with some devices, such as yours, there might be a power draw limit in the EC (Embedded Controller) on the motherboard. Not much you can do about it. With my Teclast F15, I got best results by unlocking the power limit to 12W max. If I go 15W, there is thermal throttling, because I haven’t done any thermal modding yet. You can browse my Gekkbench results here: https://browser.geekbench.com/user/Azylisk

    From what I’ve seen, for the Teclast F15 device the are actually 2 revisions: K3D5, such as mine, and the K3D8. From browsing the Geekbench results, it seems that the K3D8 revision might be slighty better than the K3D5 one.

    I really don’t think that this is the case because when I set the maximum battery in intel graphics plan in power options it doesn’t lower the clocks and also at high performance settings I don’t get even a second of clocks higher than 450 Mhz. At 50 degrees cant be thermal throttling. I will try to make a new installation of windows rather than just reseting the tablet.

    This is what happens when you buy a tablet that Chris hasn’t reviewed 😛

    BTW I get decent geekbench 4 scores regardless the power limits  https://browser.geekbench.com/user/274688

    @georgo85 You could try to use http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/page-1089#post-10984318 see if that makes a difference, just set IGPU=15 in ThrottleStop.INI

    For my device it did, because it increased my average framerate from 30-35fps to 40-45fps in Dota 2 (FullHD, minimal settings).

    Good luck!
