Good news: found a way to increase TDP limit on ezbook 3 pro (N3450 Apollo Lake & N4100 Gemini Lake)

if you put it in the startup folder it is there permanently until you disable it

This will drain battery faster though, right? Seeing as the CPU is working harder.

[Chupa]

it is all a balance between long running time and a fast computer with a bright display  – you can have a 8 hours or less than half the time depending your needs.

You can even restrict the pc via TS or RW to run with reduced power.

I reduced a 35watt i7 to 6watt via the multiplier and a turbo block
was still running with 8 processors but each below 1GHZ instead of 2.5 / 3.2Ghz

Doesn’t work on Acer swift 1 with a N4200. Entered different hex combinations and the info does update in HWINFO64 to reflect the removed power limitations, however, when monitoring the actual power consumption, it will not go above 6w. I guess Acer has found a way to lock it down. Cinebench scores do not change.

Bios manufacturer is Insyde and not AMI.

[Chupa]

so your acer is not that swift. Did you notice that this is a Jumper forum, for a Chinese low quality brand?
how about checking in an acer forum?
or even better go to throttle stop and check there.
it works with my asus, hp , jumper, thomson, t-bao, and sony

Hey everyone!

So…

I have an Apollo Lake N3350 CPU and I tried the memory patch .exe file and to no avail, still just 6w.  It’s an ECS LIVA Q mini computer, check it out, it’s insanely tiny.  It has a heatsink and active fan as well.

Any suggestions?

Also is there might be a possibility I could just do it manually if I knew what word or byte in a certain area of memory to look for to modify?  Not sure if the exe is applying the change to the right memory location for an N3350? Or is it all the same regardless of Apollo Lake model? (I’m assuming no?)

[Chupa]

the n3350 is often choosen to keep the power usage way down. it has half the cpu capacity of the n3450 and often comes with a total locked bios.
I tried the same N4000 2processores instead of 4 and even throttle stop could not get it faster. it was locked to 6W and not over 60ºC – the throttling would set in. It was a lenovo 15.6″ and was horrible slow. Took me 5 min to test and bring it back.

tested on lenovo ideapa 330 14igm with n5000 at TDP of 6w, failed.

Awww, bummer…

There’s just gotta be a way, maybe a different memory location to modify? If only I could load in a custom bios, but that just sounds like a bad idea in general.

Thanks man! I wonder if I could try using ThrottleStop on it.  Although I have no idea what parameters to modify under ThrottleStop.  I looked at the interface and had no idea where to begin…

read my diary, then you know

Chupa –
using the ThrottleStop I was able to change the burst time from 6w for 10 seconds to 15w for 65535 seconds.  This change was seen using HWiNFO64

Although the TDP was not changed (still seen as 6w) the max burst was changed and there was a significant difference seen in terms of performance.  Using Throttlestop’s benchmarking tool, stock time was 250 seconds, with the change applied at 15w, the time returned was 92.2.  Massive difference.

So Throttlestop works for the N3350, you might want to update your diary. 😉

[Crossfade14]

Did I understand it correctly, that in case I have flashed the modified unlocked BIOS and disabled power limits there, then I do not need to use Throttlestop or the manula memory writing, as these will just add a limit ontop again (even though a higher limit than originally)?

Because my problem is, that nothings seems to change anything. I flashed the unlocked BIOS and disabled power limits there. Then I made some benchmarks (Passmark – PerformanceTest and Unigine Heaven and two games) and results for ether no futher change to settings or with Throttlestop (15W, longest burst period; yes I locked settings and clicked on “on”) or with RW.exe and cmd commands for 15W, results/scores/fps are always the same (around 160 in Unigine Heaven) and do not even differ from before flashing the bios and doing the heatsink mod.

What makes me so curious is, that somehow during Heaven benchmark (so heavy graphics testing) the cpu does NOT stay at around 1,9 level but does throttle down quite al lot even though it uses only around 9W and temperature is just about 60°C. So nether the electric nor the thermal limit is reached, yet it throttles. As long as I just use CPU related tasks it stays at max speed but as soon as the GPU comes along aswell, it stays at 2100Mhz CPU and 700Mhz GPU @*11-13W for some seconds, before it then goes down to about 1700-1900Mhz (CPU) and ~450-550Mhz (GPU) @8,5-9W and stays on this level.

So what could be the reason for not seeing any improvement? Why does it still throttle that much? Could it be connected somehow to the GPU multiplier/ratio? Why seems the GPU to be stuck at 450Mhz in 99% of the time when a game is running even though 700Mhz could be the burst rate and nether Celcius nor Watt are anywhere close limits. Is it somehow possible to also address the GPU clock speed from memory with RW? To somehow “force” it to boost or at least to tell the GPU that there is no need to throtte currently. All fixes here seem to focus on the CPU (yes I know its an internal GPU)

This thread made me think about it, unfortunately i have not the knowledge to dig deeper into this.

https://www.overclockers.com/forums/showthread.php/788464-Change-ratio-on-Apollo-lake-soc-and-intel-HD500

To clarify on thing on the screenshot: The sensor graphs and logs were not running right from the beginning. So the graphs just show the “lower” level afer a couple of seconds and not the 2100Mhz (CPU) / 700Mhz (GPU) @11-13W level from the first seconds.

 

EDIT: I tested some more and noticed that if I use H.264 x264 Codec (which just uses the CPU) in Handbrake then Throttlestop stays at about 2100Mhz and 9W with just about 59°C after 15min. So this is obviously the cpu limit and thats fine. But if I use the H.264 Intel QSV codec (which also uses the iGPU) speed starts at 2100Mhz and 600-700Mhz GPU and about 12W and after some minutes it drops to constant 9W, 1700-1900Mhz and 450Mhz(GPU) and throttlestop shows that throttling is engaded and stays there even though temperature never exeedes 61°C . So even with the new limits or without limits the CPU is not possible to keep MAX CPU AND MAX GPU speed constantly because of throttling. And this throttling cannot be due to power limits (9W instead of 15W or unlimited) nor can it be due to temperature (61°C …). Is there anything that we can change so that the N3450 stays at its first boost speed? (yes, best performance in Intel HD driver and Windows is activated)

start throttlestop

set in tpl the turbo time limit to maximum
don’t 4get the turn on button

i set the temps in the bios all 15 degrees higher
now throttling begins at 85ºC

processor is designed for 105ºC, so plenty of security.

read through my help section for more info

but remember the processor is not ventilated, so everything will get quite warm

my jumper 3s runs a max of 15w sustained and 18.5w battery bar discharge rate and can do that for a long time

Did  anyone attach an   EXE thats sets the TDP to 15w or unlimited ? Ive just read through the whole thread and can only see the 10w EXE attached, on page 1 i think,  Also in regards to making a shortcut in RWEverything, is it just better to make a BAT file and put it on the RWEverything folder ?

Thanks

1. Open Notepad 2. Write (or copypaste) there the command which raises the tdp limit 3. Save the file “tdp.bat” on the same directory where is the RW-everything program (rw.exe) 4. Drag and drop the tdp.bat on the desktop with second mouse button and choose make a shortcut Now when you double-click the shortcut it runs the .bat file which contains the rw-command from here. Profit.

Hi and thanks for this, i having a bit of a problem when trying to do this, when i try to save the bat file into the RWEverything directory it tells me i dont have admin permission, ive checked my username and I definitely have full control, so that is weirdd. And also it asks me not save it in ANSI, Do i choose Unicode from the drop down list instead ? The way i have been doing it is just saving it into my user file, then copy and pasting it into the RWEverything directory

ty 🙂
