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

[Tokat]

Hi Joes321 nice Work i have a Question can i use your Tool with locked BIOS or Not ?

And Second Question is can i use ThrottleStop with locked BIOS? Please Help me !?

[Chupa]

you can both use with a locked bios because it is changed in the running PC. PC off, change gone. Just click it to start when you want it.

Hello,

I have the same problem like @bezisek, I’m able to increase TDP with Throttle Stop (e.g. 12 Watts, like shown in the last post by @Chupa), but under load the TDP returns to 9 Watts after ~28 seconds. Turbo Time Limit is set to the maximum.

Could someone solve this problem or has an idea how to fix that issue?

Thank you!

[Chupa]

I am sure you pressed the turn on button on the TS main page, YES?

turbo time limit extension is for medium loads like encoding etc. When your temp goes over a certain point 75-85 C a forced cool down throttling is started. This is to safe your processor from getting cocked and die.
There are 2 kinds of jobs, one creates lots of processor load and another creates lots of heat. So you can have 9 watt and the processor gets cocked and a 13 watt usage and your processor is still below the critical limits. Naturally these can be combined in any way.

Also to make this overclocking work you need to enhance your thermal design, because the normal design is only for 6 or 9 watt depending the thermal transfer plate.

just a few examples:

t1 just normal torture test via prime95
t2 also added handbrake re-encoding at x265
t3 prime95 switched to maximum power torture test
t4 now it is really time to stop this 15 min torture, my lap gets hot

Yes, I turned on the “turn on” button. 🙂

I haven’t thermal problems, I have done the copper heat sink mod. Under load with Prime95 I only reach 52°C, when thermal throttling starts (after 28 sec). After 15 mins Prime95, I never get about 60°C. So this can´t be the reason… :/

I have BIOS Version 5.12, 12/05/2017 and Windows 10 Build 1709, which one do you have?

It would be nice to get the TDP increase running without flashing BIOS.

I tried the same settings like you have and some other, if I put TTL to the minimum there is no difference. Always after 28 seconds thermal throttling begins. Only the watt settings are taken over correctly. So I can type in 12 or 15 watts and they will work for 28 seconds.

check lock and click apply

then use handbrake.fr and re-encode a video file in x265 for 10 min.

put throttlestop on top and watch the speed and thermals

the temp could be around 75 C

the speed should stay at 1.9 but could go down to 1.6 if you have other jobs in the background working.

before you start, check that there is nothing much running ™

in my 8 min sample the temp went max 77C and the speed stayed 1.9 what is the max for 4 processes and it stayed permanent around 9.5 w

oh, and check this with HWinfo, if it looks different send screenshot

Hi guys, first time poster here, nice to meet you all.

I just got a Jumper 3 Pro, the 12.05.2017 locked bios one. I’ve done the thermal mod as advised by Chris and tried the TDP boost using Chupa’s Throttlestop tips.

The changes show up on HW Info but I get the same benchmark scores. I’ve used the Passmark software and Novabench.

Any idea why this happens? Thanks guys.

[Chupa]

your Jumper jumps into full speed 2100MHz no matter what. Normally for 30 to 45 seconds, then it gets too warm an throttles to the half turbo speed around 1600MHz. The normal operating speed is 1100MHz and the low power energy saver is around 800 MHz.

Now here comes you, bright eyed and bushy tailed to test you new toy. As long as the time limit (maybe yours is deactivated already in the bios) is not reached (or used my throttlestop setting) AND the high temperature sensor is not triggert your Jumper will run  like there is no tomorrow and keep the max speed (as 1.9 show  in throttle stop) in reality 2100 MHz for all 4 until you stop.
If you run a single core test you Jumper can even do 2200MHZ while the other 3 takes a smoke somewhere (not literally)

If you test, use several monitors especially  the build in locky  locky via CTRL, SHIFT and ESC

to understand your processors better, watch them at work doing different things.

Oh and the N3450 has a Thermal Designed Power from 6Watt
Thermal Design Power (TDP) represents the average power, in watts, the processor dissipates when operating at Base Frequency with all cores active under an Intel-defined, high-complexity workload. Refer to Datasheet for thermal solution requirements.

9Watt is just for the overclocking burst frequency (turbo mode 45 sec).
Burst frequency is the maximum single core frequency at which the processor is capable of operating.

So you have one core @2200Hz (good warm) or all 4 cores @2100MHz (hot hot hot)

Now your Scenario Design Power (SDP) is just 4 Watt (pic)
<p class=”intro”>Scenario Design Power (SDP) is an additional thermal reference point meant to represent thermally relevant device usage in real-world environmental scenarios. It balances performance and power requirements across system workloads to represent real-world power usage. Reference product technical documentation for full power specifications.</p>
So be aware, as with every machine, if you get to the limits and over it has consequences. Your computer is designed for the specs what it came out of the box. If you tinker you better improve the thermals first.
Have a look what I did first, installing an A4 (little shorter than legal sheet) sized 0.5mm thick metal plate with contact to the main cooling plate for better heat transfer. it is still not perfect, but that was all i had on hand. It will be redesigned to make it even more efficient.

Sorry for my late answer, I had some struggle with installing M.2 SSD. I used Handbrake.fr according to your instruction, after 28 sec it went down to 9  (8,9-9,1) Watts TDP Limit. Max Temp after 7:32 mins was 54°C, as you can see.

My HWinfo is showing me an extra point “CPU Power Limit 1 – Long Duration” with unlimited duration. Depending on which Settings I choose in Throttle Stop the values in HWinfo are changing.

Same for me as well.

I see you still run with 4 processor at full speed and just 50C temp, that is very good.
You see the throttle was engaged but you are still run back at full steam. That´s all you will get.
9 W is the max we can get the rest is trickery where certain circumstances let us show higher values.

Please keep in mind that the actual TS was just fixed to barely work with the N3450 (I talked to the programmer).
Also values are sometimes wrong represented.

Also I could tinker in my bios with some temp ranges what i still have no idea what they do. (I have screenshots in my diary here.)
If you Jumper keeps running at 9 watts over a long time and you are below 60C you have all done good.

I can get 13 Watt spikes and even 14 watt spikes in extreme situations but my temps go very fast into the red zone.

Cheers Chupa, TS is doing its’ thing and I get constant 9-10W delivery with 65 degrees max after 4 hours of Hearthstone.

Any idea if there’s a way to alocate more ram to the igpu or if that’s likely to make a difference?
