The ThrottleStop Guide

i've came across this before and we conversed through pm. the old xps m2010 with OC cpu would downclock and lock itself on 25% of MOD clock during simple thing like browsing and gaming but will never trip itself on a TS bench.

im not sure if its similar to this guy's case, OS being put to sleep and would freeze after where he'll pass some heavier tests.

i've seen similar issue with my 8700k laptop where they passes IBT/XTU and TS test, but light workload background stuff will crash the computer and BSOD on idle.

imo its best to test each of these scenarios, but in any of these i've never tried p95 avx because it is unrealistic and I personally dont think any of my workload will be as heavy as that. hence the reason if it passes p95 avx it'll pass most.

 

This lenovo has a really low thermal throttling temp: 80°C (I read this is a common issue with Lenovo and low TDP machines).

- Prime95 (AVX, Single Thread) this laptop will begin thermal throttling at 3,4 - 3,5 Ghz.- No Errors
- Prime95 26.6 (No AVX, Single Thread), thermal throttling at 4,0 - 4,1 Ghz. - No Errors
- Ts Bench (Single Thread) thermal throttling will occur at 4,3 - 4,4 Ghz. - Errors

There's a huge sustained 1Ghz difference between Prime95 (AVX) and TS Bench.
I don't know maybe that's the main difference with different tests approaches.

 

might have to change pl1/pl2 values as long as laptop allows it. if it it'll always throttle and you just couldnt do those tests

 

Yeah, the laptop allows to change PL1/PL2 but on each of the above mentioned tests, the throttiling was thermal even with default 15W PL1.

 

Hello everyone !

To anybody who has one of these cpus:

i7-8700k
i7-9700k
i9-9900k

Would it be possible for you to post a screenshot like this:

http://forum.notebookreview.com/attachments/tsbench-png.175216/

showing complete turbo per core stock values ?

Hope in your help !

 

Most throttling at 80°C is almost always power limit related. When testing, it is best to have ThrottleStop Limit Reasons opened up so you can watch to see what lights up in red. That indicates the reason for throttling. The official throttling temperature is on the main ThrottleStop screen beside the word PROCHOT. Post some screenshots so we can all learn something new.

@xklis - CPU World lists the default turbo multipliers for the 8700K but not for the other two.

http://www.cpu-world.com/CPUs/Core_i7/Intel-Core i7 i7-8700K.html

The screenshot you posted shows that the CPU Cache offset voltage is at the default value. This usually has to be set equal to the CPU core offset voltage so the under volt or over volt will work correctly. ThrottleStop lets you set these differently but the CPU will ignore any voltage request that it does not understand. I do not have access to any modern hardware for testing purposes. The documentation from Intel is non-existent so in situations like that, I try to leave options open so users can experiment. Just cause TS lets you do something does not guarantee that it will work.

 

Thanks for info.
I'm just interested in complete turbo per core stock values of those cpu.
Intel just specifies base and turbo (1core) speeds, while "turbo fivr control" clearly shows every speed at every number of cores used.
That's why i asked in this thread.

 

Here are a couple of screenshots running TS Bench and showing Limit Reasons.
First one Single Threaded test and the other one with 8 Threads.
I increased TPL1 to 20w (instead of 15) but Temp will never go above 80°C in either test.

 

Intel is good at hiding their secrets but really, what's the secret? They need a dose of Ryzen 3000 to smarten them up.

@pantezuma - Thanks for the interesting pics. You are right. Something is limiting your CPU to 80°C which is not usual. On your computer, PROCHOT is set to 96°C. That is when your laptop is supposed to start thermal throttling. If you look at ThrottleStop, there is a check mark beside the PROCHOT box which means at some point, your CPU reached 96°C. Before testing, make sure to click on that box to clear the PROCHOT flag from the CPU.

It is almost like the 80°C limit was thrown on after the fact or perhaps after a power limit was reached or who knows. If you want to help with the investigation, can you try running my RegReport program?

RegReport
https://drive.google.com/open?id=0B0dpSo9k93jDVTZ6WXhDUVlrUFU



Click on the Report button and RegReport will create a new file called Report.txt in your RegReport folder. You can open it up and have a look at it. It will just show a bunch of numbers. No secret bank info or anything like that. It will show me the present value of all of the registers within your CPU. You can attach this report to your next post or you can send it to me in a private message. I am just curious where this 80°C temperature limit might have been set. Click on the Report button when your CPU is throttling and THERMAL is red in Limit Reasons.

My daughter's Lenovo laptop does not have any kooky limits like this. It runs at full speed, way beyond the 15W TDP limit, right up to the PROCHOT temperature without any issues. This is how a properly designed laptop should work. Full speed ahead.



Edit - Interesting. The older and slower 8550U can pull twice as many watts during the TS Bench test compared to your new and improved 8565U. The 8550U is also running 30% faster in this 8 thread test. Maybe Lenovo engineering got in trouble for leaving so many things wide open for TS to take advantage of.

I also noticed that you do not have Speed Shift enabled. This too is unusual for an 8th Gen U series laptop. Speed Shift is usually enabled by the bios. Have you ever tried enabling Speed Shift? It probably will not solve this problem but you might like it.

You can copy this file to your ThrottleStop directory if you want to create a Lenovo TS version.

@unclewebb - I'm having an issue with EDP Other yellow flashing and often turning red under the limit reasons. Any idea of what in my setup would cause this?

Specs:
i7-7700HQ
16 GB Ram
Repasted GPU and CPU with Grizzly kryonaut
Nvidia 1060 6GB
Windows 10

Here is a link to images of my setup: https://imgur.com/a/vM1tyIl

Please let me know if you need any more information from me. Thank you in advance.

 

@unclewebb

Thanks for your detailed reply.
May I ask what model your daughter laptop is?

If you google "80°C thermal throttling" you will find a lot of Intel laptop users of different manufacturers complaining about this issue!
Somewhere I read something regarding an offset temp from PROCHOT, set by some manufacturers which only can be modified by bios modding. I'm no expert so, who knows.
A few comments:

1) PROCHOT flag is not checked until I start the test, so something happens just a second from starting it.
2) Tried enabling Speed Shift but no difference made (Gonna try to search in Bios but as far as I can remember the Bios is pretty basic and didn't see such an option).
3) This laptop has a particular issue where changing TPL limit will only work after resuming from sleep. Never would work after cold boot (I mentioned this to you a few weeks ago, but doubt you remember!).

In the report.txt laptop has already been into a sleep - awake cycle, so TPL could be modified to 20w and the report was taken during an 8 thread test with thermal throttling in red.
Hope you find this useful and will be awaiting your comments and learning if there's a way to improve this thing!

Hello!

I have strange problem with my system. In short - when GPU get hot more then 52°C it sent signal (or something like that) to CPU to drop frequency on base level (for my i7-3820QM it's 2.7 GHz).

What i do:

1. Run Valley Benchmark to load GPU,
2. GPU get hot and drop frequency from 3.5 GHz (or so) to 2.7 GHz;
3. I press "Turn on" and "Turn off" in ThrottleStop and frequency back to 3.5 GHz (or so) even if GPU is hot now.

How to avoid that frequency drop? I may check "BD Prochot" checkbox, but it didn't help - frequency drop anyway. Only if i also check "Set Multiplier" and then press "Turn On" it will never happen.

I recorded videos:

Here is start


I have to stop recording, since Bnadicam runned on dGPU and temp wont drop.

Second video:

After GPU temp drop below 52°C i runned Bandicam record again.

 

Thank you Papusan!
Didn't even think about wikipedia! (hope they are correct values though !)
Thanks again!

But i see that it lacks of mobile cpus info about complete turbo values.
Here you can find i7-i9-xeon cpus (thanks to those who contributed):

Check Set Multiplier and Turn On.

 

Hello Unclewebb, Im having the same issues with an HP Omen 15 (i7 8750H). The voltage resets (with TS still running on background) when I wake up from sleep. Any idea what can it be?
I was checking if there is any option in the task scheduler to (re)start TS after waking up the laptop, but didnt see any.

EDIT: seems to be the cache offset the only one who gets reset
EDIT2: Nvm, Im not sure what happens, sometimes its fine a -250 cpu / -143 cache, sometimes crashes at -220/-144, sometimes temps get up to 90s in few seconds ,sometimes up to 70s, maybe the temps are related to fans control thought

 

@T[]RK - On some Lenovo laptops like my Y510P, Lenovo thought it would be a good idea to disable Intel Turbo Boost when the Nvidia GPU is active. It does not happen immediately. It just quietly happens in the background while gaming so users were not always aware that their CPU performance was taking a hit. The trick I use to fix this problem is I set the FIVR Non Turbo Ratio to 1. Problem solved. This eliminates this type of throttling.



If that does not work, you can usually solve this problem using the Set Multiplier feature.

It is a Lenovo C930. Great sound for a thin and light laptop. Generally overpriced but it was much more reasonable when I found it available on one of their weekend sales at ~$1050 USD. This was on the Lenovo Canada website. The prices are always high on the U.S. site. She is happy. It has been a good little laptop so far with no more throttling. It is a good laptop for school.

A stable laptop should never crash. When setting up an undervolt, do not adjust it so it is right on the very edge of crashing. Give your CPU some extra voltage so you do not have to constantly worry about it.

The bios is supposed to reset your voltages when you resume from sleep or hibernate. If ThrottleStop is running in the background, it will usually take care of this problem. Intel XTU is more hit or miss after resuming. There are fewer complaints about this on the web when using TS. Any laptop can block CPU voltage control when starting up or resuming. I avoid talking about this subject in the forums. Laptops are more fun when their CPU voltages can be tweaked.

A 6 core CPU in a laptop can heat up so rapidly that a poorly engineered fan profile can definitely be a problem. Manufacturers believe that consumers would rather have a quiet laptop compared to a functional one. The complaint call center phones light up when aggressive fans kick in while gaming.

 

I reinstalled chipset drivers, and seems the behaviours isnt repeating itself, but I barely tested. It was weird, because sometimes just getting on Overwatch menu, CPU temps got to 90ºs, but when I re-set the cache uv again, they drop down to 70ºs, with same CPU speed (3,9GHz).

I noticed lowest uv that TS bench dont give any error is -130mv for botch cpu/cache , but temps are so high, that im currently using -240/-143 because I have been able to play with no problems for many hours staright. But I know I will eventually have to relax the uv if I get crashes.

 

@Temp1234453 - If you have come up with an undervolt that works well when gaming, set up a ThrottleStop profile for that purpose. When not gaming, switch to a profile with a less aggressive undervolt for better stability. Setup a couple of keyboard shortcuts and you should be able to easily switch profiles on the fly, even when in game.

 

True, havent thought of that. I should have done that when I had my 4700mq, which couldnt handle over -40mv on idle/low load, but could get over -100mv while gaming.
Thanks again Unclewebb

 

Hello. Could you tell me, how can I limit the frequency of the processor in this program? I want to specify a specific value above which the frequency should not be.

 

What CPU are you using? Have you tried lowering the FIVR - Turbo Ratio Limits? Post some more details and some pics so I do not have to play the guessing game.

 

I'm using throttlestop on a MSI GS65 RTX 2060 laptop--I have created a task in task scheduler to start throttlestop when I log in as per Bob of All Trade's instructions ( )--however, when my computer boots it initially loads and turns on throttlestop only for a few seconds and then throttlestop turns off (switches from red system tray icon to green color) . . . I then have to manually open the program to turn it back on and then it functions normally for the rest of that login session. Any ideas?

Thanks,
N123

 

@N123 - Try following the Task Scheduler guide that I posted in the second post of this thread.

http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/#post-6865107

The Task Scheduler has a few options that do not work like one would expect. I will go check out the video you posted to see if I can see anything obvious. I have zero issues after following the guide I posted.

Edit - BoB is a good guy and I enjoy his videos but I wish he would follow my Task Scheduler guide. I watched his video and noticed that he left out some important details.

Pay attention to the part about making sure that items in the Task Scheduler that are grayed out are not grayed out. They must specifically be turned off. My guide, with help from @Papusan , clearly explains this.

 

Thank you--following your excellent guide helped/solved my problem

 

Thank's for your answer. My CPU is i5-8300H. I don't tried to do that because i don't know how it works. Could you tell me? I only read this guide - https://www.notebookcheck.net/How-t...ife-The-ThrottleStop-Guide-2017.213140.0.html

 

To reduce your maximum processor speed, lower the Turbo Ratio Limits.

That is how it works.

Do not be afraid to experiment. What is the worst that can happen? Your computer crashes and you have to reboot? Do not add ThrottleStop to your Windows startup sequence until you are comfortable and confident that your settings are reasonably stable.

If you are truly afraid of using ThrottleStop then you should probably not be using it.

 

hey guys, what's the state of Throttlestop on windows 1903?
I'm updating right know, I hope it works... If not, we always have Intel XTU (even though it's now as good as TS).

 

No issues at all on multiple systems I know of.

 

Hey @unclewebb , I seemed to have stumbled upon something reproducible that's been driving me insane trying to figure it out. I'm not sure if it is documented elsewhere, but it is related to my Dell 7577 laptop and its reluctance to put its CPU Package into the C7 power state.

[Fast forward through ~2 hours of testing]

I finally figured out exactly what was going on:

I could only seem to get C7 Package power state consistently while on "Balanced" power plan (and only after screwing with the EPP battery power slider and/or plugging/unplugging from power) and noticed the "Ultimate Performance" plan would prevent my machine from using its higher C7 Package state almost always. The weird part is though, I could get my CPU into the C7 Package state seemingly randomly or intermittently. I figured out how to be able to "trick" my CPU into the deeper C7 Package state while running on the higher powered "Ultimate Performance" plan by switching power plans and messing with the EPP slider and TS's EPP check box, etc while keeping the TS C State window open (so I could see when and what was changing). However I noticed as soon as I closed the C State window, my workaround was lost and I could not get C7 Package state back again until more messing about and going back and forth.

Anyways, I was digging through my power settings and comparing a few of the "advanced" power options and finally determined the specific cause. If you recall from one of my posts some time ago, I had concluded the cause of my machine not consistently entering the C7 Package state to be directly related to the AHCI Link Power Management - HIPM / DIPM state. ( See this thread here that brought it all together.)

That was on Win10 v17xx. I noticed on v1903 that I have since upgraded to that I have an additional option "AHCI Link Power Management - Adaptive" that I don't recall seeing before. As soon as I set that value from "0" (disabled) to "100" ms, my C7 Package states came back consistently on the "Ultimate Performance" plan without any other screwing around regarding the EPP or battery slider, etc. Note the "AHCI Link Power Management - HIPM/DIPM" setting cannot be set to "Active" as that is the equivalent of setting the "AHCI Link Power Management - Adaptive" setting to "0" (disabled).

I also discovered there was an additional option "SEC NVMe Idle Timeout" that appears to be the NVMe equivalent of "AHCI Link Power Management - Adaptive" but it had no effect on my CPU Package C states. Case closed (until the next major Windows Update effs up my beautifully tuned laptop again).

 

Hey, @unclewebb
Did you have the chance to check report.txt for thermal throttling?
Thanks!

 

The Throttlestop is always shut down after i unplug the laptop. Why?

 

Try following the Task Scheduler guide from A to Z in post #2 of this thread (pay attention on the Red text in one of the pictures in the guide). Read also the explanation from Unclewebb about the Task Scheduler in this post http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/page-1023#post-10921267

 

This is really important. I have been noticing similar issues with my XPS 15 and X1/P1 laptops. I had to cold shutdown and restart to get it back, seemingly after every time I connected to my TB3 eGPU. I will see if this affects it.

 

I need help with thermal throttling of my i7-8750H in GS65 Stealth 8SE with RTX 2060.

So far I've made the following changes in throttlestop:
-Undervolted cpu core and cpu cache to -140.6 (computer crashes at -150)
-Enabled speed shift (also in TPL) and set to "0" for my A/C (plugged) in "performance mode"
-unchecked BD Prochot
-left everything else at the throttlestop default settings including leaving speedstep and C1E checked
-on the windows side of things, I leave my PC in "balanced mode"; when the laptop is plugged in the battery slider in the system tray is set right in the middle of the slider range with the power mode saying "better performance"
-I've also setup a custom fan curve so my laptop fans are running full blast when the system is under stress

Although my temperatures and battery life are much better with the above, the main issue with my CPU performance does appear to be temperature throttling on multi-thread workloads and not power-limit throttling--my CPU hits 90 degrees pretty quickly in this instance and throttles down to 3200-3400MH. My cinebenchR20 is stuck at 2458 and my firestrike physics score 14879--this is below average for an i7-8750 per my understanding--for example, physics scores in firestrike over 16,000 should be easily attainable with the i7-8750h per my understanding.

(for what it's worth, when I run cinebenchR20 single thread workload or the parts of firestrike/timespy that are not CPU intensive, I get sustained cpu clockspeeds in the mid high 3900MHz range and my temps are great in the 70's and sometimes 80's) . . . the main issue is the tasks that really peg the CPU....

What are the next things that I should try in throttlestop (or other) to improve multithread temperatures?

Thanks,
N123

 

Jacked up the base to un-restrict fan intakes? (if your model has bottom intakes)

Undervolt and max fans are the main things in terms of software/firmware. Opening its guts up and making sure the heatsink is aligned well, and using a better TIM, are all that's left for you really, which isn't without work or risk (especially in the case of the best TIM, liquid metal)

Thinnnn, powerful, cool - can only pick two.

 

Thanks--I saw somewhere that someone achieved better thermals by applying a larger undervolt to the CPU core and a smaller undervolt to the CPU cache, the idea being that the CPU cache is much more sensitive to undervolt-induced crash than the CPU core...

Is it safe/valid to use different undervolts for the CPU core vs cache?

 

No. With Conductonaut and some bios tweak it is possible the three:

 

I used an $8 tube of Noctua NT-H1 and was able to achieve R20 score of 3099 out of the i7-8750H with no throttling of any kind. There's more than one way to skin a cat, as they say.

Regarding undervolt for Core and Cache, the 8750H seems to benefit from a staggered undervolt like this. I'm currently -0.165v core and -0.135v cache with good results.

 

Unfortuanly, my Lenovo IdeaPad Y500 have got Ivy Bridge CPU, so no FIVR option for me.

Maybe it's really accident, but i tested connection temp between CPU and GPU. And it's really between 52-53 degree. I saw it in HWINFO64 how graph go down when temp higher and up when temp is lower. I add load when temp around 50 and graph doing down again, i let it cool down and it jump up.

If dig dipper, where it may be? Both Y510p and Y500 have got unlocked BIOS versions. Is it possible to find any kind of flags there? Disable it in BIOS firmware and flash it on laptop.

There already was removed white list for WLAN, removed whitelist for eGPU, maybe there is also something for this.

 

For Ivy Bridge, try clicking on the TRL button. I believe the Non Turbo Ratio setting is in that window. Try setting it to 1. If that does not work, you will need to use the Set Multiplier option. That should work.

Setting the Non Turbo Ratio is just a better way of solving this problem because it takes zero CPU cycles. Low cost, high reward.

I have been slacking off on ThrottleStop, especially during the summer. I downloaded your report, had a quick look but I have not found anything yet. If I do, I will post the results here.

 

Hey unclewebb, i have a question for you, ive acer predator with i5-8300h, no matter how hard i try i cant get past cpu 45watt power limit using throttlestop throttles my cpu to 3.2 ghz when it happens, but this processor have max core speed of 3.9ghz, looks like firmware blocking throttlestop's overrides, what if i use a unlocked bios and set power limits from there it would work? i cant try it right now, because this laptop have locked bios, i will need a spi programmer for it. If you say it gonna work i will buy one spi programmer and unlock my bios. thanks for throttlestop which still does wonders.

 

Hi.
I am trying to use ThrottleStop to undervolt my laptop, however because of the layout of the program, I am unable to use keyboard to access certain features like the FIVR window, or setting the offset voltage etc.
I am blind, and keyboard is necessery for me when it comes to using programs.
So if possible, can I have some help on using ThrottleStop in it's current state, or as a request to the developer, could keyboard usability be taken into account in the next update?
Thanks in advance.

 

Have you tried using the FIVR - Disable and Lock Turbo Power Limits feature? That works on some laptops to overcome the 45 Watt barrier.

I have no idea if your plan will work. If you want to try unlocking your bios and if you need to buy a spi programmer when something goes wrong, that is up to you.

@Robgeta - My apologies. ThrottleStop is not a keyboard friendly program and I do not have any plans to update it to make it more keyboard friendly. What CPU do you have? If you could share your ThrottleStop.INI configuration file, I might be able to edit it so you would have a basic under volt. I am not sure how else I can help. You are probably going to need someone with better vision and a mouse to help you out with ThrottleStop.

 

@unclewedd... I have a GPD win2 with a cor N3 7Y30 processor in it.
I want to give an undervolt to the CPU and GPU to decrease temperature and to allow the GPU to have more headroom to opporate at max frequency.
If you could create a configuration file for it, I would be grateful.

Why don't you have plans to expand on keyboard compatibility for the program?
For blind users like myself who have experience with computers, we would rather be independent than have to rely on others constantly for programs like this.

 

Kindly take a few moments to think about what you wrote.

 

Yes i tried Disable and Lock Turbo Power Limits feature it didnt work either

 

@pressing... edited. :d

 

If that is the case, you are pretty much screwed unless you can come up with a modified bios. Even with a modified bios, there is still no guarantee. Let me know if you get this working.

I have never run ThrottleStop on a Core m3-7Y30. ThrottleStop supports a lot of different CPUs that I do not have and have never had access to. It would be nice if I had one of everything that Intel has ever built but my house and my wallet is not big enough for that. I do not know what ThrottleStop features are available on that processor. Your best bet is to go to a GPD specific forum and see if someone with your exact same CPU would be willing to share his ThrottleStop.INI configuration file with you. Copy his configuration file into your ThrottleStop folder and then start ThrottleStop and see what happens.

I have no plans at the moment to do any more ThrottleStop development. I always have some ideas and I have even considered writing a completely new version that is more logically laid out. I do not have enough time for what I would like to do so this project has been sitting idle for a while now.

 

too good of a software to let it stay idle. try start fund raise and see how many people are interested, especially with all the new CPUs from AMD/Intel you maybe surprised to see how many would love to use throttlestop over XTU or ryzen master.

make this software worth your time again!
