Feature to Disable EDP throttling on TUF F15 2022.

[AnujJena]

Hello guys,

ASUS Tuf F15, i7 12700H, RTX 3060 (140W).

While "Plugged in" and gaming the i7 12700H, power consumption drops from 45 to 25 Watts, because of EDP throttling.
This happens only when the charge is not at 100%. And while gaming the charge keeps dropping from 100% even if it's plugged in.

The screenshots below show the average power of CPU and GPU before and after the battery reaches 99%, you can see the battery level in the last column.

The avg clock speed of the CPU decreases as well.

This causes a performance drop in every game significantly.

The CPU Electrical design point becomes "YES" when the battery drops to 99%.

@AnujJena does Armoury Crate allow to control that anyhow? If not - then probably it's hardcoded in bios.

Try ThrottleStop app for finetuning your Intel settings.

@seerge Here it is,
I hope this is what you needed, XD

@AnujJena hello, thanks for the dump :) I honestly, don't see anything there that would tip me that it's related to all this "throttle" modes you are talking about. It could be some tricky proprietary thing very specific to your model. So without physical device and lots of tinkering it will be impossible to figure it out.

Does lowering charge rate to 80% remove this throttling thing if you go below 100% ?

[AnujJena]

@seerge Hello, and thank you for looking into this for me, I really appreciate it,
Lowering the charge below 80% or lower has no change.
However, after changing the ThrottleModeOnAC to 0, the CPU Throttling gets disabled for some games, while it stays on for some games.
Its really weird.

However, what stays constant is a 200 Watt power limit for CPU+GPU+Misc.
Was there anything in the dump indicating a 200 Watts power cap?

As when the CPU is at 45 Watts, the GPU maxes at 115 Watts, and when the CPU stays at 35 Watts the GPU boosts upto 125 Watts.

It could be that this setting configures Intel Dynamic Tuning (Intel Innovation Platform). This is present on any Intel laptop and will dynamically change PL1/PL2 and dynamic boost of the GPU depending on some settings in a ACPI Table that is hidden somewhere and can only be changed through some "magic" API that is not publicly documented.

[AnujJena]

Yeah, it seems to be the Dynamic Tuning changing the power.
But the I still havent found what causes the TUF F15 model to have a 200 Watt power limit,
because when I tested the same games on a Lenovo Legion 5i and ROG M16, with the same specs,
those laptops had 220 Watts power where as TUF F15 gets locked at 200 Watts,
its not even thermal throttling.

This is a well-known issue for Chinese TUF users.
When the battery is not fully charged, ASUS has limited the total power consumption of CPU+GPU to 160 watts.

Unfortunately, there is currently no known solution to fix this problem. Many users have reported the issue to ASUS, who promised to release a BIOS update to address it. However, it appears they have yet to follow through on that promise and may never do so.

Thankfully, there are a few methods that can help alleviate the issue.

1. One option is to use "Standard mode" and connect an external monitor via DP/HDMI, as the overall power restriction only applies in dGPU mode.
2. Another option involves turning off all e-cores, unlocking bios advanced options, and disabling Intel Dynamic Tuning and Nvidia Dynamic Boost. After doing so, limiting CPU power (PL1/PL2) to 45w will allow for stable CPU/GPU power at 45+115w for an extended period.

[XyKER1]

Yeah so I tried your method and it gives the CPU 15 more watts (up to 40 watts, not 45), which is still a substantial improvement over 25. It still looks like there is no way to increase CPU+GPU power past 140 watts, as ASUS knows this will cause battery drain. I tried changing ThrottleModeonDC to 0, which I think would actually fix this issue (as it probably stops throttling when battery is being used - which happens on this laptop while total draw is above 140 watts), and I got frequent graphical bugs and crashes (probably meaning the GPU isn't getting enough power). ThrottleModeonAC doesn't change anything for me. I'll going to keep trying to fix this but I have a feeling there won't be a way to get long term power draw up to the 160 W it can sustain while at 100% battery.

I think it's not simply just battery drain , look at the pics I sent below , even after water cooling , CPU can still gets to 66C , under normal condition , both CPU and GPU are under 60C if water cool. If this is done without water cool , I am pretty sure , CPU would reach throttle temp of 100C.

[AnujJena]

Disabling Dynamic boost enables the CPU to draw 45 Watts, but limits the GPU below at 100 Watts.
Is there any possible way to re-enable GPU boost?

And it is really weird that disabling Intel Dynamic boost, limits the GPU Boost.

[IceStormNG]

It is not weird at all. Nvidia Dynamic Boost and Dynamic Tuning work hand in hand.
The Dynamic Boost works by relocating unused CPU Power budget to the GPU. For this to work, Dynamic Tuning tries to predict how much CPU load and how much GPU load is running to prioritize either GPU or CPU. If Dynamic Boost does not free up power budget from the CPU, the GPU cannot take it.
Without dynamic tuning, the GPU is locked to its TGP and cannot boost.

[AnujJena]

@IceStormNG I see, it makes sense.

About this , I recently modified my Tuf F15 2022 with water cooling , if i done testing water cooling I wanted to clean install windows and make a fresh start with laptop. But before the clean install , I was using the laptop for about a week. I have some drivers from TUF F15 2023 installed ( since one varient of TUF F15 2023 [FX507ZV] comes with i7-12700H). I played games like Valorant and i saw CPU is using 60W and GPU is using 135W , total power comsumption is so high , even at plug-in state , my laptop battery down from 100 to 68. I thought CPU is capable of using so much power because of low temperature from water cooling.

Then I did a clean-install of windows, and i still install some of TUF 15 2023 (FX507ZV) drivers , but the total power consumption is back to normal , even with water cooling enabled , CPU is only using about 30W and GPU about 110-125W. I am still trying to replicate that high total power consumption like last time , but still not successful.

[AnujJena]

Okay, makes sense.

[AnujJena]

@IceStormNG Going off topic for a bit, can you help me deciding which RTX 4060 laptop would be a good choice?
A laptop that will not have an EDP throttling like the TUF Intel series.

Would TUF A15 2023 be a good model?

[IceStormNG]

All models have EDP Throttle. It is the CPU that does that mainly + BIOS current limitations set by EC or VRs. I have no experience with the TUFs though, I always went with the Zephyrus because I like their design and the portability + performance. I only game a little bit here and there.

[XyKER1]

@AnujJena I watch Jarrod's Tech (a gaming laptop reviewer) a lot, and without a doubt, the best models other than the TUF series are Lenovo Legion or Acer Predator Helios. They're well priced, upgradeable, and don't have any major drawbacks. You could go with the TUF A15, but the other two, while maybe slightly more expensive, have better cooling and you don't run the risk of extreme EDP throttling.

[XyKER1]

@1m4g1ne Does your battery discharge while playing games with your water cooling (and fully unlocked CPU), or does it stay constant? I finally got a new game that's heavily CPU limited, so I've decided to start attempting some BIOS modifications to fix the throttling issue. This information might save me a lot of time.

[XyKER1]

Just wanted to post a final update on this situation. Two weeks ago, my TUF F15's charger broke, as it kept disconnecting and reconnecting, making me unable to do anything more intensive than light web browsing. I sent it in for repair under an extended warranty and they gave me a full refund as they were unable to fix it. I bought a Lenovo Legion with very similar specs (i7-13700H and 4060), which is so much better in every way than the TUF F15 (with the exception of the touchpad being garbage). However, it came with a 230 W adapter, and whenever the CPU+GPU power draw is above 135 W, the battery starts draining while gaming, although I can still get 70+ W on the CPU (compared to 25 W on the TUF). However, many people on Reddit have figured out that buying the 300 W adapter will stop the battery from draining.

With this in mind, I can conclude that the reason the TUF was throttling was because the adapter is not powerful enough to supply the components at 45+115 W. You can't just add up the power draws and compare them to the total adapter wattage - power supplies don't work like that.

I also had been doing an enormous amount of BIOS tinkering over the last few months, and nothing allowed the battery to drain further to improve performance.

So, the only possible way to stop this throttling is to buy the 330 W charger for ROG laptops, which looks like it has the same port shape and should work.

Ooooh... I just discovered this topic and I have the same problem on my F17 (2022) 12700H-RTX 3060. #1574

With Ghelper I had to limit my CPU to 40W and the GPU to 1700Mhz (95W-100W) to obtain acceptable performance and not exceed the throttling limit.

Thanks for sharing all of this.

[XyKER1]

I'm Raibex87 on the ROG forum and I can tell you that you don't need to read everything here (I already have). Nothing will fix this issue other than getting a new power adapter (and you can limit the GPU clock using G-Helper to allow higher CPU power draw, like you said).

[Kikimahe]

Oh Raibex87 ! :-)

Yes, I see that nothing can solve the problem. :(

I even tried reinstalling Armory Crate this afternoon (shame on me).
But obviously that didn't change anything and I immediately uninstalled it.

For buying a new power adapter, I looked at the price and it's around €200 ... Ouch.
And we are not 100% sure that fix it. ;'(

[XyKER1]

@Kikimahe The only website I'm aware of that sells official ASUS spare parts is A-Accessories, although it looks like that adapter is sold out for them. Not sure why it's so expensive for you - for me pretty much every charger on Amazon is $100 or less, although I do live in the US. I would recommend against buying from Amazon if that's what you were looking at, as aftermarket chargers are very unreliable.

I do see some listings for $45 US dollars on Ebay which say brand new OEM 330 W ROG charger with 30-day returns, so maybe there are some deals like that available in Europe.

I know it's a pain, but I'm 99.9% sure that nothing else will work considering a laptop from a completely different brand has the exact same battery drain issue with a similar CPU+GPU wattage to total adapter power ratio (135:230 on my Legion, 146:240 on the TUF). The 240 W adapter is simply not powerful enough, and even if you were able to find a way to allow battery drain, that would destroy your battery capacity rather quickly if it's draining every time you're playing games.

[XyKER1]

@Kikimahe Actually ignore what I said before, I just got the 300 W power adapter, and it doesn't make a difference. Even though my Legion Slim 5i Gen 8's thermal system can handle a lot more power, it looks like the motherboard caps the input to 230 W, so I wouldn't be surprised if ASUS did that, too. I'm going to return this and get a Legion Pro 5i which actually supports the 300 W adapter, so hopefully that won't have the battery drain issue. With that being said, there may actually not be a way to stop the EDP throttling on the TUF.

[Kikimahe]

I was thinking of buying a 330W adapter soon...
Thanks for your feedback, I wouldn't do it.

For the moment I keep the battery charged at 100% to maintain maximum performance all the time. I will replace the battery when it dies.
And when I play games, I pray that it doesn't go down to 99% :-D
