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

[wef vef]

Hi guys!

 

I have Teclast F5(N4100 – UHD600). I modded my heatsink, and replaced the termal paste. My bios is unlocked, C state is disabled, all thermal sensor, and power limit disabled. I tryed WRMSR 0x610 0x0 0x00000000. 

My cpu run always in turbo mode. When i run games, the cpu is throttling, and the TDP stuck on 6w. Sometimes the tdp run on 11w, and after 5-10 sec, throttling. The temp is low (60-70C°). When i run prime95, the cpu is not throttling, only when i run games.

Why throttling the CPU when playing games?

 

Thanks.

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.

 

Working perfectly fine on my Swift 1 N4200. https://youtu.be/BbWN-iOR0yw

Could you try an older bios?

Hi, this looks awesome. But is it possible to do it from Linux (Ubuntu) ?

Have n3450.

I’m wondering the same. I have a TV box with the N4200 and have installed Debian.

Hoping there is a way in Linux as well?

Which options may I ask? Did you notice higher battery consumption and heat?

The option is in the BIOS, you basically disable the power limit and it’ll use as much as it can, as needed. I’ve been playing with different power options to check which gives the best battery life, and which gives the best performance. The thing is, when it can burst up to high watts for a short time, it will finish the task much faster and might actually use less power. Of course, if you’re gaming, then your not doing a quick burst of power but are just using sustained power draw. So I’d say it really depends, but I hope to make a full write up in another week or so.

 

John, could you kindly point me to where I can download the BIOS update that will let me unlock the power limitations of my Voyo Vmac N4200? Is there a guide anywhere?

Thank you!

So my bios had unlocked features and one of them was remove power limit. Now it goes to 15W… I think this is maximum what that power board can deliver.

hey guys, everytime i restart the laptop the TDP limits goes back to default, is there any ways to have them locked on the limits you just choose, for example 10W ? thanks

[zoomysloppy]

Can we disable power limit exceeded? N4200 runs at 12W for about 10secs and inside HWi power limit exceeded becomes yes, cpu reduces to 6W. Can we over write this so its always no.

I RECENTLY PURCHASED APOLLO LAKE NOTEBOOK. I WAS SEARCHING FOR IT AND FOUND THIS FORUM. SO HERE IS MY GIST OF HOW TO UNLOCK TDP & CREATE SHORTCUT OF BATCH FILE. SO YOU CAN UNLOCK OR SET YOUR DESIRE TDP AT SINGLE CLICK.

HOW TO CREATE .bat FILE OF DESIRE WATT:-

1)OPEN NOTEPAD.
2)COPY & PASTE OR WRITE ONE OF THESE :-
“WRMSR 0x610 0x0 0x00DD8F00” 15W TDP
“WRMSR 0x610 0x0 0x00DD8A00” 10W TDP
“WRMSR 0x610 0x0 0x00DD8600” 6W TDP
“WRMSR 0x610 0x0 0x00000000” Remove all limits
3)SAVE THE FILE “tdp.bat”.
4)NOW MOVE THE CREATED FILE TO RW.exe folder.
5)CREATED THE SHORTCUT OF “tdp.bat” to desktop.

YOU ARE GOOD TO GO.

NEED APPLICATIONS:
1)RW everything.
2)NOTEPAD.

didnt work for me! maybe I made a mistake somewhere?

.bat seems to run instantly but nothing happens. Also tried the shortcut command solution with no success.

I recently bought a Lapbook SE and I am trying to improve the gaming performance. I did the heatsink mod and it brought down the max. temperature from 87C to 70C (at the stock 6w TDP). I’ve tried to increase the TDP for more performance, but it seems whatever I do the GPU won’t reach high clocks, it only goes up to 400-450mhz, so I think I must be doing it wrong. Please could someone advise me exactly what to do in the BIOS and in Windows? Many thanks!

I tried this on my Acer Spin 1 with a Pentium N5000 and it had no noticeable effect whether I chose 10w, 15w, or unlimited modes. This laptop seems capable of up to about 15w stock in short burst workloads, but that can last as short as 12 seconds before dropping back down to 7w sustained. This laptop rarely hits 70c, and even with tuning it so it doesn’t go over 65c, the burst limit still throttles performance to the same wattage.

[Henk De Vries]

For anyone that runs into trouble for the N4100 Gemini Lake not listening the PL1 unlock and always clamping to 6 watts:

Theres a second limiter in the MCHBAR that also holds a power limit value. Wichever is lowest ‘wins’.

Its placed in the memory at 0xFED170A8 on the Goldmont (plus) devices.

 

Setting this to zero makes the MSR power limit the only limiting factor for these processors.

My BMAX Y13 now runs at a stable 15 watts, with only the ‘copper shim mod’, at around 85 degrees centigrade(furmark gpu+cpu stress test).

I have the power limit set to 15 watts, it probably would go higher, but I’m statisfied by these performance gains, as it throttles just a little bit under full load.

I use this command to remove the second power limit.

Rw.exe /Min /Nologo /Stdout /Command=”W16 0xFED170A8 0000″

Hi,

@henkdev

Great info, I couldn’t get the GPU to hold its turbo well enough like the Apollo Lake. Disabling C-States helps also boost performance at the cost of a little battery. I used a few other ways to help also but now this works a treat! What’s the code for unlimited TDP I want to see how far I can really push this N4100.

 

Or maybe a 20W TDP. I’ve ever seen them use over 15W as a package but I wonder now if it can?

Another thing I would love to do is somehow stop the RAM from clocking down from 2400Mhz to 2133Mhz. If there is a way to force 2400Mhz DDR4 instead of the 2133Mhz all there Gemini Lakes seem to run max. The RAM spec looks like it can do it according to HWinfo and the timing.

I know it’s not much of a boost but if we can get the absolute top speeds it’s a little more of a performance gain.
