    Hey Folks,

    Just picked up a Teclast x4 and having issues unlocking my TDP. It’s rocking a N4100, but PL1 seems stuck on 6 watts.

    I’ve disabled CStates in  bios as well as power limiting. I’ve also run:

    W16 0xFED170A8 0000
    WRMSR 0x610 0x0 0x00DD8A00

    But HWiNFO still reports PL1 to be 6watts. Has anyone run into something similar and found a solution? Deffinitely not a major issue — this tablet is mostly just a pet project.

    Cheers!

    Just got an AP45 4k Minipc with a Pentium J4205 (10W). For some reason all the provided commands give me a Command Error. I figure the addresses might be different but I wouldn’t really have a good idea as to where to start. If anyone has a good guide I would appreciate it. While I was able to disable DPTF and PL1 and get my power usage up to around 15.8W I can’t seem to get it much higher except in very short bursts to ~17W.

    Furmark CPU+GPU

    J4205 (stock) – 9.996W avg, 14.788W max | 1694.1 MHz CPU & 353.2 MHz GPU | 65C Package

    J4205 (nolim) – 15.781W avg, 17.724W max | 1673.1 MHz CPU & 539.4 MHz GPU | 80C Package

    <hr />

    Now I get the feeling the stock power adapter, a 12V2A barrel jack, might be the limiting factor here given it’s only 24W max. I might need to order something with a bit more headroom given I also want to install a spare 2.5″ HDD I have… But thanks for the tip on disabling DPTF. I was wondering why disabling PL1 didn’t make a difference on it’s own.

    Hi all,

    First of all thanks Chris for his dedication on the thread.

    Reporting working as below:

    BMAX Y13 N4120, run 15w with unlimited time, 2cmx2cm copper shim mod.

    CPU: All cores 2.2~2.3GHz (can’t hit 2.5GHz as power limited)

    GPU: 500MHz (only able remain at 500MHz as power limited)

    Temp: 86 Degree

    RW batch used:

    @ECHO OFF
    CD\
    CD C:\Program Files\RW-Everything
    Rw.exe /Min /Nologo /Stdout /Command=”W16 0xFED170A8 0000″
    Rw.exe /Min /Nologo /Stdout /Command=”W16 0xFED170AC 0000″
    Rw.exe /Min /Nologo /Stdout /Command=”WRMSR 0x610 0x0 0x00008F00 0″

     

    Do trial run with the unlimited setting and max out 19+watts and the temperature shoot up too fast and not even dare to further stress test after less than the first minute. Don’t want to further stress as the intention to unlock the TDP is for performance improvement during daily usage. Sustainable YouTube 4K60FPS HDR live streaming with >250Mbps data rate.

    Battery power drain fully depend on the usage as we’re not modding any EIST setting and both CPU/GPU just use as per needed task.

    CPU-Z benchmark can get single core 204 and multicore 808 which is very good cpu performance improvement.

    If anyone still wondering the Linux equivalent of the RWEverything command, here it goes:

    1. Install busybox & msr-tools
    2. Execute these:
      busybox devmem 0xFED170A8 16 0000
      busybox devmem 0xFED170AC 16 0000
      wrmsr 0x610 0x0

    Feel free to make it autostart depending on your init system. If you use systemd, however, this unit can be used:

    [Unit] 
    After=network.service 
    
    [Service] 
    ExecStart=/etc/maximum-performance.sh 
    
    [Install] 
    WantedBy=default.target

    place it in /etc/systemd/system/maximum-performance.service, then /etc/maximum-performance.sh containing:

    #!/bin/bash 
    
    busybox devmem 0xFED170A8 16 0000 
    busybox devmem 0xFED170AC 16 0000 
    wrmsr 0x610 0x0
    
    

    and don’t forget to set the correct permission: 744 for /etc/maximum-performance.sh and 664 for /etc/systemd/system/maximum-performance.service. Then just enable it:

    sudo systemctl enable maximum-performance.sh

    Bang! Now you get unlimited power on boot. Of course you can change the value for wrmsr argument if you want some actual limit.

    Testing Geekbench 4 and 5 results in maximum 30ishW power draw and impressive results, double OpenCL, double multi-core CPU (GB5 only), 50% higher single-core CPU.

    Not bad on my dual core dual thread celeron n3350, i got around 10-15% performance, it worked!

    Hi,

    thanks for these helpful info, works perfectly with my Teclast F5 / N4100.

    But I have to do it manually in RWEverything every time because this command does not work :

    Rw.exe /Min /Nologo /Stdout /Command=”W16 0xFED170A8 0000″ (Invalid Parameter)

    Any idea ?

    dear all ,

    there is a way to launch the scrip directly at the start of windows? I put my hand on a acute angle pc (n3450) with bios lock and i do some test, moving from 6W tdp to 10W i got in a suit of test an increase of performances between 73% and 110% just with an increase of power consuption of 66%, and temperature increase only by 5°, i do stress test with 6W and max temp is 55°, at 10W temperature rise up 61)

    i try to move to 15W, in the same bech i have an increase between about 95% with a peak of 144% with a power increase of 150%. And sometime i see the cpu throtling, newer happen with 10W.

    Temperature during stress test rise up to 66°. Unfunatly stock cooler is in aluminum, in order to increase thermal exchange i add a small 1 mm foil of copper between  cpu core and cooler and change thermal paste with better one. (of course i add a layer of thermal paste between core and copper foil an between copper foil and cooler).

    So i think that 10W is the sweet point to gain a huge boost of performances avoiding huge temperare.

    So it is just “boring” to launch the script or RW everything every time, there is a way to change register once for all or launch the script automatically during the startup ?

     

    tnx

    Hi guys if you used these strings;

    W16 0xFED170A8 0000

    W16 0xFED170AC 0000

    WRMSR 0x610 0x0 0x00000000 0

    and stıll not get 700mhz on igpu  try to increase pp0 current limit on ThrottleStop

    Hi, I just updated Windows to 21H1 and RW 1.7 doesn’t work anymore when I run this:
    WRMSR 0x610 0x0 0x00DD8F00

    It stays maxed out at 6w, while I got the full ~12w before. Anyone has the same behaviour? I’m on an Atom x5-Z8300.

    just do as every of us did, lauch the script or RW and try to see if you gain something avoiding thermal throtling.  I thisk that this script work great for n series, with tdp lock at 6W…moving to 10W you really gain a lot with few degree more on the soc. I try to move my n-series from 6 to 15W and i see some problem, maybe due the “poor” heatspreader of my hardware. J series run directly to 10W, so maybe you have to try with 15W. Do some test (like unigine valley, run at default, check temperature and see the final score, run again at 15W and see how much rise the temperature and how much rise the score)

    Dear Mario,

    there is a way to create a script and launch directly at the boot of a linux system like openelec?
