The ThrottleStop Guide

Oh no, I do not mean to blame @unclewebb; I'm just trying to report the issue of those settings no longer working. I think it can be easily fixed since the parameter is still available to be modified, since XTU is able to change it. Of course the notebook manufacturers are incompetent arses and ThrottleStop is a savior.

 

That's ok good sir but...
They work as intended. At least for me. Maybe bro @Falkentyne could test on his Jokebook.

 

hello all, im new to all this and i tried with several options . with my latest settings, games are no problem, cpu is running around 3.9-4 ghz and gpu around 1.7ghz. but under prime95 stress, cpu is throttled around 3.7ghz or even lower. the lowest i saw with undervolting was 3.1ghz very heavy load. for games, temps are 55-60 degrees celcius for cpu and 60-70 for gpu.

for stress cpu prime95, PL1 appears and i get 3.7 to 3.3ghz depending on stress level. temp never goes beyond 80°C. cpu underclocks itself after sometime due to this longterm and shortterm power limit i guess.


i used -125mv for both cache and core, no undervolting for intel gpu.

msi ge73 raider i use, with i7 8750h and gtx 1060

so my question is, getting these values for stress is ok? or shall i expect higher clock speeds for cpu?

 

Hi unclewebb,
thanks very much for you explanation!
I dont want blame Lenovo, but Intel response me this issue about lost power GPU scheme is probably on Lenovo side....
But nevermind me, I managed quite simply imported that scheme and now my bench is a bit better
Anyway you are also right with that HD 2000 upgrade. .
So could I to ask somebody with knowledge here, how high are my chances if I would go for i7-3770S (becose it has HD 4000)?
It seems to me on top where I can go for my socket LGA 1155. Becose my board is OEM so I probably cant hope for any K versions is not it? Also my origin CPU was G 630 running at 65 W TDP so I guess I cannot go higher with TDP?
Any kind of advice from you I will be glad
Btw I noticed my Limit reasons are locked I can be clicking ot it as rage but nothing happened, is this standart set TS for Sandy bridge?

Thanks for your replay

 

Could you guys help me out with my settings? I have a Lenovo Ideapad with a 8250u + MX150 and I feel that some guys actually run worse if I turn on Throttlestop (live Overwatch). I fear that the amount of power is shared between the GPU and CPU so whenever I boost the CPU by allowing it to use the turbo frequencies all the time, that penalizes the GPU... not sure if that's the case. Am I doing something wrong? Can I utilize the CPU at it's maximum clock without affecting the GPU? Or, can I limit the CPU to a max where won't affect the GPU?

Here are my settings:

I do not think ThrottleStop needs to be fixed. ThrottleStop just works differently than XTU and many users think that is a good thing.

After you set the Disable and Lock Turbo Power Limits option, go into the TPL window and adjust the Turbo Boost Long and Short Power Max options. These should work correctly. For the moment, ignore what HWiNFO and AIDA64 or reporting or better yet, exit both of them. Try setting a low power limit, open up Limit Reasons and run a TS Bench test and fully load the CPU. When your CPU starts to throttle, (PL1 or PL2), have a look at the PKG Power consumption value that ThrottleStop displays. Does this not correspond with the power limits that you have just set? It is possible that HWiNFO and AIDA64 are not sampling the values the CPU is using in real time.

Maybe. Have you tried using the ThrottleStop - FIVR - Disable and Lock Turbo Power Limits feature. Are your power limits in the TPL window adjustable and have you tried increasing them while Prime95 is running to see if they can be used to get rid of the throttling? What is possible all depends on the laptop model. You will need to do some testing to find out the answer.

When I have a question like this, I do some testing. Start the TS Bench test. For a consistent load, use a 12 thread 1024M test so it lasts for a while. You can push the Stop button at any time to stop testing.

Open up the TPL window and lower both of your turbo power limits to 30. Close that window and open up Limit Reasons. Is your CPU throttling? Does it show PL1 or PL2 glowing in red? Has the CPU multiplier significantly decreased? Does TS show a PKG Power value similar to 30? Did the reported Package Temp to the right of the PKG Power decrease? Post a TS screenshot while this test is running so other users can learn what you have just learned.

@marccdb - Have you tried using the FIVR Disable and Lock Turbo Power Limits feature yet? If I was having power limit issues, that would be the first thing I would try. After that, turn on Nvidia monitoring in ThrottleStop and turn on the Log File option. Go play a game for 15 minutes and when you are done, exit ThrottleStop and go into the ThrottleStop Logs directory and post a log file of your CPU's performance. It will help show if something is throttling. A big drop in CPU MHz or GPU temps are good signs of throttling. You could also use GPU-Z to monitor your GPU speed while gaming.

 

@unclewebb are there documents or white papers from Intel to understand what each option in Throttlestop does? Thanks!

Is the PL3 limit set by the BIOS before booting the OS?

another stupid question, why didn't you put " Disable and Lock Turbo Power Limits " under TPL? It took me a while to figure it out.

 

@abujafar - Intel offers a lot of documentation to the public but some of it is like Swiss cheese. Here is some light bedtime reading.

https://software.intel.com/en-us/articles/intel-sdm

The voltage control features in the FIVR window are not publicly documented by Intel. You only get access to the good stuff if you are a multi-million dollar company and you are willing to sign your life away. My friend Dufus is responsible for the majority of ThrottleStop's many features including all of the FIVR voltage controls. TS Limit Reasons is a direct copy of his Limit Reasons program.

I assume that PL3 is set by the bios.

Disable and Lock Turbo Power Limits was an experimental feature. I was not sure if it was going to be useful so I added it to where I had some space available. The TPL window had become bloated and was on a diet at the time so I did not want to add anything in there. Once I move the Speed Shift stuff out of the TPL window, there will be plenty of room for the Disable & Lock feature in the TPL window where it naturally belongs.

Time for some testing. The first picture shows a desktop CPU throttling.



When 4 cores are active, a Core i5-7600 that is not throttling should be using the 39 multiplier. You can see that the multiplier is below that so this CPU is throttling. Why? Limit Reasons shows that PL2 is the main cause. What is the PL2 limit set to in TS? 36. What does ThrottleStop show for PKG Power? 36.0 W

This seems to be working OK.

Next, I used TS to drop the turbo power limits to 15.



ThrottleStop reports PKG Power at 15.0 W and the multi has dropped significantly to an average of 18.83. Definitely some serious throttling in progress. PL2 continues to light up in Limit Reasons so it is the source of this misery. The drop in CPU power consumption has also caused a drop in the CPU package temperature.

As long as a person disables the secondary power limits using the FIVR - Disable & Lock feature, you should be able to use the primary power limit adjusters in TS - TPL to control the CPU performance and power limits.

Intel XTU combines these limits so it adjusts both of them at the same time. My decision to get rid of the secondary limits is much more useful. It can be used to eliminate DPTF throttling as well as many other ill-conceived throttling schemes. At the end of the day, that is what ThrottleStop is all about.

 

Thanks for the link!
Volume 3 - Chapter 14 seems the most relevant

Also I can confirm that what you described works on my i7-8750H in the XPS15. I even successfully my turbo time limit to 56secs
I kind of figured out on my own what you just did but used cinebench as stessor.

Thanks, this explanation about two layers of power limits makes a lot of sense. I really wish I would know more about this subject!!!

 

Me too!

There is also a third set of turbo power limits. The CPU constantly compares all of them and uses the lowest power limit. TS and XTU cannot get to this third set of power limits. Best to keep quiet before some manufacturer comes up with a great idea to make our lives miserable.

 

@unclewebb , I tried disable and lock turbo power limits, with installing the config file first. But I couldnt observe the effect in HWInfo. it was still 45W. Also during stress test, even though I changed the default 28seconds for max turbo timer to maximum, I am still having PL1 power limit. during stress test, I am getting, for example, 50-60W pck power but, after 20~ seconds, PL1 shows up and my frequency drops down to 3.4GHz sometimes, or to give a range, 3.1-3.5 GHz.

I checked BIOS for some settings about power limit but I couldnt find anything, also I tried to increase the power limit and lock it after enabling Disable and Lock Turbo Power Limits to 55W for example but, I didnt observe a change.

During games though, for example Withcher 3, I just downloaded and tested, I get 3.9-4GHz CPU and 1.7Ghz GPU with 98% Load usually. Temperature-wise, they all look ok, CPU is never over 65 degrees celcius, GPU is never over 75 degrees celcius, its also note to worth that I didnt observe spikes or FPS drops during the testing. I got 40+ FPS during gaming which should be normal I guess for the GPU.

Is there any other way to test this TPL limits and observe the effect? I tried to increase like I said but, I didnt see any effect, the maximum power after 30 seconds of stress test is 45W even though I was locking to 50-55W for example.

 

@unclewebb - I've two question for you if you please answer. First; Do you recommend using the feature "Disable and Lock Turbo Power Limits", i still didn't get how does this function works. Second; Do i have to click "Clamp" for Long and Short Power Max in TPL.

 

Hello.

I use TT in Dell xps 15 9570. Very good programm, thank you.

But i have an issues.

I limit miltiplier to 34(max is 41) and udervolt to -0.200.
All ok, but when my laptop went to hybernation, and then i turs it on, the TT works not correctly. It does not limit multiplier to 34, it limits it to 41(cpu-z says about it). If i open FIVR and closed it, it will help and multiplier limits to 34.
This issues appears only with hybernation mode. If i shutdown laptop or go to sleep mode all is ok.

Can you help me with my problem?

 

@Cooler-master - I had same kind of problem. If i shutdown TS is not keeping the same multiplier i choose earlier.

 

Here's the issue i am having. "VR CURRENT"

 

Oh, this does work! Thank you for the clarification. I apologize for having made an assumption.

Wow, I did not know there is not one, not two, but THREE sets of power limits! This information fits perfectly with what I'm seeing on my Razer Blade Stealth. I believe the third power limit is programmed in the EC firmware. On Blade 15, "Gaming Mode" in Razer Synapse changes power limit from 35W to 45W. Stealth replaced that with an even more pathetic "Lower Power Mode" that limits package power to 8W. According to RWEverything, it switches EC register 5F from 00 to 03. I put in 03 manually in RWE to try to induce Low Power mode myself to no effect. Anyone got an idea how to get rid of this type of power throttling? I've got access to all the BIOS menus thanks to AFUWIN and AMIBCP; I have already changed the power in "Config TDP Configurations" to no effect.

 

When I was looking around in the unlocked MSI laptop BIOS, there are PL3 and PL4 but the settings are empty.

 

Maybe. Can you post a screenshot of the FIVR window? I am using Windows 10 and on my desktop computer, the FIVR Turbo Ratio Limit values are correctly restored after I resume from Sleep or Hibernate mode as long as ThrottleStop is left running.

Can you increase the VR Current limit in your bios? This might be a limitation of your motherboard. The VR section may have been under designed.

ThrottleStop has to be running so it can control your multiplier. If you exit ThrottleStop or if you reboot and do not run ThrottleStop, it will have no control of your CPU. Post a screenshot of the FIVR window.

Yes. I always recommend using that option.

No. I never recommend clicking on the Clamp option. I like a fast CPU, not a slow CPU.

The 8750H is a 45W CPU. Some manufacturers enforce this rating. Many do not. If this limit is being enforced on your laptop by the EC, you will not be able to run your 8750H fully loaded at its full Intel rated speed.

@Zeddi is able to run Cinebench on his 8750H while maintaining the full 39 multiplier for the entire test.
http://forum.notebookreview.com/thr...ongfang-gk5cn6z.815943/page-320#post-10851360

An empty setting usually means that a power limit is not being used. Intel provides a wide range of throttling options. Too many in my opinion. No one forces manufacturers to throttle the crap out of their laptops. It is their choice.

Dear @unclewebb ,

Thanks a lot for the answers. I just tested again with cinebench and, after setting as Zeddi, I was able to achieve full time 39 multiplier for entire test. Then I switched the test to prime95 and, I saw only for 60 seconds or so, I was able to maintain the full 39 multiplier. Even if I increase the turbo time limit and PP0 turbo time limit, the result was roughly 60 seconds still. My temps were not even over 80 °C. During the cinebench, I see 50W and more than 45W usually.

With 45W, during prime95, it goes back to 3.8GHz with 38 multiplier with max fan, around 65°C stable. It still feels like CPU can do more because first 60 seconds is more like 50W+ and keeping 39 full multiplier at all times, no spikes and temp is also around 75°C. Somehow, the time limit is restricted maybe?

 

By design mine Intel® Core™ i7-6700HQ work on 3500mhz with 1 core loaded and if all 4 cores are loaded its speed will be 3100mhz. Can i somehow correct this via subj? To have 3500mhz on all cores loaded.

Thx!

 

Your only options if you have access to increasing the base clock (BCKL) frequency. Maybe you'll get 100MHz more before you hit the wall or run into stability problems. And you have the power limits wall put by Intel as well. Best options... Undervolt as much as possible.

 

You can't do 3.5GHz on all cores.

 

Max BCLK you can use is 2.98%, but you need unlocked bios and ME Engine FW mod.
So max you can achive is 3192 on all 4 cores and 3604 on 1 core.
But you need a bit of knowlage to do this. But you need to know that by puting higher BCLK you will be OCing not only CPU Cores but also CPU Cach, RAM, IGPU, and also FCLK and PCIE if I am correct.
Correct me if I am wrong.
Sometimes everything works great like on my MSI laptop but sometimes you can hit the wall at 1%bclk. There can be problems with booting because of ram problems. your wifi card may lose connection. Also you can brick it by bad bios mod or by breaking the me Engine.
I f***** me FW once and I needed Svet help and his me unlocker tool to recover it. because I could not gain CPU access to recover ME. Realtek audio Pin mod was not help for me. Second try worked for me.
if you are still want to try and push everything to Max give it a try. Many of us here have knowlage to bring you back from sh**.
I can advise you know that it is nice to have programer because enything can go wrong.
Toutorials for how to gain access for ocerclocking by bclk and unlocking BIOSes are easy to find via Google. But because of your question I am not be that guy who would give you all The info because I don't want to be responsible for any damage that may come frome misunderstandings. If you come back with some Basic and more advanced knowlage then I and many others will help you

BR

Edit: For now you should learn more about maxing your current performance from cpu and gpu. Try what @Papusan said also work more with for example gpu curve in MSI afterburner. And find out how Windows is wasting your cpu ram resources. You would be suprised how much of performance is wasted.

What is funny I came across post on mobile Pascal tdp tweaker, were some guy moded tdp of gtx1060 to achive higher performance. after modding from 78W to 110W he was able to achive around 13450 graphics score. My gtx 1600 van achive The same score without moding tdp. So you now can see my point about tweaking and maxing your current hardware.
Of course i plan to mod my Gtx 1060 tdp but currently no time for that

again BR

 

No. The 6700HQ is a locked CPU. You need a K series to increase the turbo multipliers beyond their default spec.

Yes it is restricted. ThrottleStop allows you to request a huge time limit but the CPU will ignore any request outside of what it considers to be a normal range. If you ask for 1000 seconds and it does not understand this request, maybe it will only give you 60. I have never found any documentation that explains this. I left ThrottleStop wide open so users can experiment.

Have a look at how terrible many expensive laptops are running Cinebench.
https://www.notebookcheck.net/Dell-...GTX-1050-Ti-Max-Q-Laptop-Review.355641.0.html

After a Dell XPS 15 9570 warms up a little, performance falls off a cliff. And that is with the much more expensive 8950HK. If you can run Cinebench with a 39 multiplier for the entire test then you are doing much better than the majority of laptops with 8750H processors.

Most laptops are limited by power limits and not temperature limits.

Prime95 is not a realistic load for a laptop with a 6 core CPU. You are probably going to be able to run most everything else at full speed so be happy with that.

 

Odd situation with power limiting on Dell XPS 9550 (6300HQ). Two main issues:

1. 45W CPU Package is capped at 35W

2. Any undervolt to CPU core & cache drops Pkg power to 25W (tried both ThrottleStop and XTU)

3. Any ideas to get this running at 45W?

- ThrottleStop shows (factory default) turbo boost short and long of 56W and 45W, respectively. I have changed that to 65W and 55W with ThrottleStop & RWEverything. Tried with fancy new ThrottleStop "Disable and lock turbo power limits". Also tried with Intel XTU. (edit- Also tried lower thresholds like 55W and 55W.)

- Running Prime 95 alone, the CPU package max 35W

- Runing Prime 95 with TS, the CPU package max 35W

- Running Prime 95 with TS & undervolt package max 25W (FIVR screen, CPU core & cache only, any voltage offset, although say a tiny 25mV drops CPU package max to just ~32W). (edit - same general "bad" behavior with Intel XTU). Used same voltage offset for core & cache; did not undervolt other areas.

- ThrottleStop shows TDP level 1 and level 2 of 35W and 0W, respectively. I don't think this is the issue. I can set "TDP Level Control" in ThrottleStop to 0 (and it stays there all the time per "HWiNfo Current cTDP Level"). I can't change TDP Level Control to 2 (tried via TS and locking register via RWEverything 0xFED15F50 80000002)

- ThrottleStop has shown "limit reasons" "Ring EDP Other" in yellow for years (Max VR Voltage, ICC Max, PL4 in HWiNFO flagging). Sometimes these are not flagging. Usually not flagging when running Prime95.

- TS Bench runs at CPU package max 22W

- Tried:
* rebooting
* safe mode
* a few versions of ThrottleStop
* newest Intel XTU
* Different Windows Power Schemes
* SpeedShift
* BD PROCHOT
* Disable and lock turbo power limits
* Options in Dell Command-Power Manager (also deleted program and shut down system)
* etc.

Any ideas?

People should stopp support companies who destroy own products.

 

@pressing - The screenshots you posted show 100% load and all 4 cores are showing the 28.00 multiplier. That is the maximum speed for a 6300HQ when 4 cores are active. That is not throttling. Same thing for the screenshot that @Papusan posted. HWiNFO is reporting the 28 multiplier for all 4 cores. It is running as fast as Intel designed it to run.

http://www.cpu-world.com/CPUs/Core_i5/Intel-Core i5-6300HQ Mobile processor.html

The 45 Watt number is a maximum rating. If it does not need 45 Watts to run at full speed, that is OK.

It is not unusual for some things to be flagged yellow in Limit Reasons after your boot up. It is only important if they are glowing or flashing red while the CPU is loaded. That and a lower multiplier will confirm throttling.

 

For me, I tested with some games and CPU is below 80, usually below 75 and around 70 °C with multiplier 39 all the way. So no throttling in CPU and also for GPU, its the same, max is 73-75°C and max clock.

@unclewebb, thanks a lot for explanations and insight. I cleared my doubts and I appreciate the support.

 

Thank you.
I want to limit ratio to 34. CPU is 8750H in DELL XPS 15 9570.
But after hibernate ratio is 41! You can see it on HW info screenshot. Max freq is 4100 mHz.

 

Okay, guess i'll stay with this advice:

Any good guide on this?

 

@Cooler-master - I tested this on my 7th Gen desktop computer and the Turbo Ratio Limits were being applied correctly after resuming from Sleep or Hibernate mode. Instead of showing me HWiNFO, can you show me a screenshot of ThrottleStop so I can see how you have it setup. Run a single thread of the TS Bench and take a screenshot of ThrottleStop while that test is running so I can see what it shows when a load is applied to the CPU.

HWiNFO is showing me that the CPU is running at 1097 MHz so I am not sure when that max speed was recorded.

Edit - Is it possible that ThrottleStop is not using the Performance profile in your screenshot?

Is your computer going into Sleep mode and then automatically going directly into Hibernate mode after that?

Anyone else having this problem? Anyone not having this problem?

 

Thank you for the reply!

The problem exists only with hibernate mode. In sleep mode all is OK.

1. I start my laptop after hibernate
2. Run any game or heavy programm or cpu test and the cpu shows ratio 39-41.
3. I open FIVR in TS and press "OK".
4. Run any game or heavy programm or cpu test and see ratio 34.

I captured a small video with my problem.

And also take screenshot.

I have not any system timer. Laptop goes in hibernate mode when i close lid only.

I think TS is using Perfomance profile.

 

I have same kind of problem, when i restart my notebook. I will send screenshot later.

 

@Cooler-master - Thanks for the information and taking the time to upload a video. If you can do some testing for me, I will try to get this problem figured out for you. I will send you a test version of TS in a day or two.

@onrblbl - No need to send me a screenshot. I will send the test version of TS to you too when it is done.

 

Thank you!
I will do what you need.

 

I appreciate for your support, thank you.

 

Is the rise of Uncore Power Consumption when using Throttlestop on i7 8550U a known Bug?
I dont want to use it if it triples my idle power consumption of the cpu on my Laptop :/

 

I have recently seen the "high Uncore power consumption" bug but I do not know what is causing this. What testing have you done? Is ThrottleStop causing this or is it another monitoring app causing this or is it a bug within the CPU itself? If you are running HWiNFO, AIDA64, HWMonitor or any other monitoring utilities, try turning them off one by one. Turn off ThrottleStop too.

The power consumption data reported by software is only an estimate of actual power consumption. It is possible that there is a bug within these CPUs that is causing high Uncore numbers. Not sure yet. Try using Sleep mode or Hibernate mode and then resume and see if anything changes.

I do not own an 8th Gen CPU to do any testing with. ThrottleStop has not changed in recent memory so it is interesting that this just started happening recently and only on some 8th Gen CPUs. I think I have seen this bug on an 8750H as well but I do not think that they all have this bug.

Edit - 8750H Examples





Can anyone explain why two different 8750H CPUs at a very similar load show a huge difference in reported power consumption? If ThrottleStop is showing only 0.6 Watts for Package Power on one CPU, that has me thinking that ThrottleStop is probably not the problem. The question then is, what is the problem? A bad driver or a bug within the CPU itself are my guesses.

 

You could also ask yourself... Is this behaviour more common for some brands notebook models vs. others? Need more data than a few showed.

 

Some people (e.g. on MSI notebooks) use imon offsets to reduce throttle, so the OS reported Watts are cut in half or more and no longer represent 'accurate' power reading estimates.
Often user are not aware because systems are already sold hard-coded like that by reseller.

 

@unclewebb I have an 8750H here on an XPS15. I haven't noticed this behavior but I will keep an eye on it.

In your screenshots, I notice 2 differences.
1) The EPP is set to 128 in one case and to 0 in the other. If I do that I get an increase in power consumption but nowhere near 12W.
2) In the second screenshot, C3 is at 63% while in the first is 0.1 (presumably it is in C7).
Also, we can't see the last 2 cores.

 

Thanks for your Answer!!
So, i have a few Infos and Maybe also an idea what is causing the difference on your screenshots.

First of: My Laptop is a Samsung NP900X3T with the i7-8550U. I check the Power consumption with CoreTemp (only Monitoring tool running), not with Throttlestop. The "Uncore" is an estimate, yes, but the package power is not an estimate. CoreTemp is comparing IA-Cores and GPU with total package consumption so in my mind, this is a very good estimate.

When idling, my Package Power is between 0,1Watt and 0,3Watt in total, 0,1-0,2Watts are for Uncore and 0,1Watts are for IA Cores, which totals to max 0,3Watts most of the time.
As soon as i start TS, The Uncore stays fixed at a Minimum of 0,5Watts. Without even using a Setting. Even when i completely close TS, the High Power Draw is staying. I have to reboot the machine for it going away. I did not try Sleep Mode, but i will Test.


So with your Pr(oblem with 8750H-CPU (I assume, that most Laptops with this CPU have a powerful Nvidia-GPU built-in): In a Clevo-Gaming Laptop with an i5-8600 Desktop-Class CPU, i have a similar behaviour. It has to do with Optimus Technology and the switch to the dedicated GPU. Idling without the GPU, the package Power is roughly 1Watts. As soon as the dGPU is triggered (even for a short time), the Package Power is Minimum 10Watts for 5-10 seconds before going down again (because GPU is disabled again).
The Problem is, until today there is a bug in Windows 10 or the Nvidia or Intel Driver that randomly triggers the dGPU even when not needed: https://answers.microsoft.com/en-us...-problem/93e7004a-62b1-4211-8e37-4c136608865e
(In my Opinion, this is not partially fixed at all, it is still the same mess, even with most recent Windows and Driver updates)

This would be one possibility, why your second screenshot Shows a power Draw of 12.8W. This is roughly the 10.8Watts of Uncore (its Always the same) and 2Watts of IA Cores added together.

Package Power Overview:
Idle, dGPU not active: 1Watt
Idle, dGPU idle: ~11.8Watt min
Idle, dGPU doing Stuff (try the nvidia Control Panel 3D Animation with Spinning nvidia logo): 4Watts

The Uncore Power Drops, the higher the dGPU Clock in my understanding. But only with inactive dGPU you get best idle Uncore Power of 0,6Watts in my example.

I hope i could help

 

Eh? I noticed this exact behaviour on my i5/7-XXXXU CPUs with Nvidia's dedicated graphics. C states would be limited to C2/C3 for a few when the dedicated GPU is on. Windows would wake the inactive dGPU for a few seconds, even when doing seemingly simple tasks, for example, opening Windows Explorer or closing a program. This was especially terrible in 1803 iirc, where the entire system would lock up for a few seconds while Windows or the CPU waited for the dGPU to go back to sleep. This happened almost every time the user closed a heavy program for some reason.

That being said, my 8250U would use 1.4W during said dGPU wakeup for a few seconds. The Package would not go below C3.

 

I've found this option but i didn't wanna touch it. This must be the reason then. This value goes over 250...

Intel CPUs do not measure their power consumption. All power readings are only estimates.

This does not make much sense. The reported Package Power includes the Intel CPU cores and the Intel GPU. Power consumption of an Nvidia GPU is not included in the package power number that software reports.

Exactly. Different C States and EPP values, etc. will make a slight difference but a 12W difference with the vast majority of that being the Uncore is hard to explain.

I agree. I just posted the first two pictures I came across. Same 8750H CPU but two different laptops. I hope to find someone with one laptop that has this problem where sometimes the Uncore watts are low at idle and sometimes they are high at idle for no apparent reason. On a low power U CPU with a 15W TDP, a huge change in calculated power consumption like this would kill maximum performance and cause a lot of throttling.

Live a little. Bump it up and see if that throttling flag goes away. What is the worst that can happen?

How do you have ThrottleStop setup? Can you post a picture? After you exit ThrottleStop, any changes to the CPU will be maintained until something else comes along and changes things. Are you using any ThrottleStop features that change your CPU in any way?

 

Burning my notebook

 

If it's a non- overclockable CPU, no need to worry. If its locked it's also fine to increase it. No damage and no risk at all. I7 6700HQ and I7 7700HQ are locked and non- overclockable. I think the new i7 8750H is also locked like the earlier, others correct me if I'm wrong

 

CPU Voltage Regulator Current Limit value goes really far like 250... That's why i said like that.

 

Unless it is under my hand.... i7 6700HQ and also i7 7700HQ can be unlocked too
This is mine...



About i7 8750H I guess in the future we will know
