The ThrottleStop Guide

I also use Process Explorer when monitoring badly behaving software.

https://technet.microsoft.com/en-us/sysinternals/processexplorer

The Windows 10 Task Manager seems to have incorporated some of those features. Microsoft liked their software so much that they bought them and made them part of Microsoft.

 

win10 Pro x64
when open the hyper-v, ThrottleStop 8.10 Beta 2 display performance = 0;
then cannot change PP0 Current Limit value ,is locked 29

 

Tried latest version 8.10 beta 2. It cannot minimize into notification area and keep remain on the start menu task bar (Windows 7 64 bits). Even I tried to set minimize option with startup & ThrottleStop option set as start as minimize, close to minimize & uncheck task bar still cannot working. Is there any solution for this?

 

Yes. Just run ThrottleStop from Task Scheduler. Define trigger - start when I log into system and it will start and stay active in the background. With CPU-Z you can see, that your settings are active (for example undervolting).

 

I recall myself having troubles with TS icon on taskbar on newer versions and nothing helped.
Now my old MSI laptop is temporary bricked and I tested latest TS on old Lenovo T410 and interesting enough there is no problem on this machine. What is happening with this taskbar thing?

 

If you are having icon problems, clean the Windows Icon Cache. Directions how to do this are at the bottom of the ReadMe file that is included in the ThrottleStop download.

If you are having problems, post a picture of ThrottleStop that shows the problem.

ThrottleStop reads and writes information directly to hardware registers within the CPU. That means ThrottleStop is probably not going to work correctly in a VM.

Edit - Skylake testing is in progress. Intel's high performance monitoring timers have worked pretty much the same since the Core 2 Duo era. Starting with Skylake, Intel has made some changes so the monitoring methods that ThrottleStop has been using for many generations need to be changed to properly support Skylake. Not much money in the piggy bank so I decided to start testing with a low end Core i3-6100. Some BCLK overclocking shows that ThrottleStop needs an update.



When overclocking a locked Skylake CPU, you lose power consumption reporting, core temperature reporting and the C States do not work either. Cheap MHz has a price.

 

Hopefully the below will be of some use

 

thanks a lot for throttlestop with powercut option,you're amazing !!!! no more throttling with my 4700mq @3.6/3.4ghz with a 770m@1050mhz , ~same temperature as before on full load and little higher average power consumption in my msi soft.
can we auto activate powercut with a command when throttlestop is launched ? when i reboot/shutdown my pc, there is a reset/restore bios (the "cliic") and i need to réactivate it everytime .


edit : maybe a bug ; after a lot of bench/stresstest a Core "MPO" flashing red/yellow say hello after my last occt test: cpu(60%)/gpu(99%)/memory(90%) ,no real throttle appear but FID get stucks at 34 max i can just lower the ratio but normaly it was ~36 at rest and low usage. reboot fixe my issue and not be able to reproduce with the simple TSbench



little screen of TSbench and average power consumption in occt power supply test

@unclewebb ,

i 've a problem with Throttlestop under windows 10, that it's not saving my settings after a reboot (i need to disable PD_PROCHOT and EIST (and i klick save) otherwise my CPU & GPU not working proper (using admin-rights)).

Interesting is when i start Throttlestop after the reboot, PD_PROCHOT & EIST are already disabled and from this moment on it's working - i mean after i see the GUI of Throttlestop (and the process shows up in windows taskmanager) it's working and i can close Throttlestop and it's keeping PD_PROCHOT & EIST disabled for this windows session until the next windows startup...

after the next reboot the the same thing happens...

(this also happens during the previous beta)

do you have any ideas what's causing this issue?

thank you a lot for your great tool - without i could kick my notebook into the garbage!

 

nicely done, more than 8c/8t support. i find it nice you added shortcut, is it possible to have a gadget of this built in? i find that your cpu temp is by far the most accurate in comparison to other ones like cpu meter, pc meter, hwinfo64. those tend to lower cpu temp by 4-7c however those got gadgets lol.

 

I was wondering if anybody could help me fix my Toshiba encore WT8-A-102. I used throttlestop 8 beta and now my CPU is stuck at 0.52ghz and I have even tried to reinstall windows 10 but to no avail any help would be appreciated thanks

 

Think TDP throttling on a 15w 6560u /iris could be ameliorated with the TDP clamp? Stopping the cpu from going above 8w or so would probably hurt clock speeds a lot

 

Hi guys ! I want to undervolt my 4720hq because my temps are high . During heavy load will spike to 92 C . It doesnt throttle if i do a stress test useing XTU , but if I do a gpu stress test in the same time , then it will throttle. I can't change thermal paste or smth because this laptop is 6 months old . I never done this before so I need some tips On how to do this. Ty very much !

 

What does 6 months old have to do with change the thermal paste?
Advice: change the thermal paste

also- do any of the TPL options work on skylake u-series CPUs? it seems to have no effect. My 6560u is running at 1200 mhz CPU 700 mhz GPU during firestrike bench due to TDP, not temp.

This is frustrating. There is so much more room for performance if there was some way of increasing the tdp on Skylake processors.

 

Hi. Thanks for your reply. I downloaded TS 810 2b (which I hope is the latest version...?) and it recognised my CPU just fine even though it's a desktop computer with a desktop CPU (i5 4590S). When I opened the FIVR (not that I even know what that stands for the new window gave me the options I was looking for in the Turbo Ratio Limits box, i.e. it let me choose the Turbo Boost depending on the number of cores being used/load. (My CPU Intel specified max Turbo Boost with active 4 cores is 3.3 GHz, 3 cores it's 3.4GHz, 2 cores it's 3.6 GHz and single core it's 3.7 GHz.) I set my preferred Turbo under 1/2/3/4 core active to 3.7 GHz, I clicked apply and nothing happens - my max turbo under 4 core load is still the factory designated 3.3 GHz. I then noticed in the top left of the Turbo Ratio Limit box an option which you can tick called Overclock. This is grayed out and I cannot tick it. Is this the reason why my new turbo ratio limits aren't being applied? Can I overcome this? Thank you. P.S. I forgot to mention that no, I didn't go full retard and forget to click Turn On button on TS after I tried to apply the above mentioned changes

 

try bios reset? reset cmos see if that help.

 

If i would open it and change the thermal paste like you said, I would lose the waranty. I have 18 months of warranty . So this is not an option for me . Thats way I was thinking to undervolt .

 

most of the time, thermal paste isnt the problem be very honest. dust blocking vent, or just laptop heatsink isnt designed to cool properly on the cpu. rather than undervolting, see if you can either turn off hyperthreading in bios, or simply lower the clock frequency with throttlestop, theres no other way to go about this.

 

I wanted to keep it running as best as it can so I don't want to lower the clock or turn off hyperthreading. So the best ideea to make in cooler is undervolting . Btw ,i've downloaded TS 8.1

 

How will they know you've opened it?

 

Agreed... Unless it is a MSI with all their warranty labels, they won't know.. The high temps can be solved by a repaste or send it in to a service centre to be repasted.. Personally I would do it myself to save all the hassle of loosig your laptop for a few days!

Sent from my LG-H811 using Tapatalk

 

tbh even the sticker can be tampered but that would be unethical.

and another fact, repaste doesn't do much unless at underload with max fan speed, or at least the fan spins high enough to show the difference. reason behind that is because EC or w/e profile system has set the fan to activate at a certain speed when hardware hits a certain temperature. even with a better paste, it'll still hit that temperature which triggers the fan, it may delay by a bit before hitting that temp with a better paste thats about it.

however underload, if theres an option to turn on max fan then a better paste would show it's difference through temp differenece.

 

gotta find which one is more important to u. temp + fan noise or system performance. if a heatsink isn't designed to fully take a certain amount of dissipation then you're only option is to lower the clock, unless of course, you mod heatsink.

 

It's Asus x550jx . 4720hq, gtx950m

 

Both are important. And I hear alot about undervolting and how this can lower my temps , so I wanna give it a try . But im new at this kind of things . Never used TS before. I want to know how to undervolt it a bit ,mby i can get a few degrees lower . How should I start and what's the worst thing that could happen . Thank you all for answers !

 

that all dependent on your bios and mobo. if voltage regulation is doable then in throttlestop u'll be looking for a button called "TRL". under extra voltage basically lower that to 0. if your mobo allows it and cpu is supported by throttlestop it should be available, if not it'll be grayed out, normally u'll need an unlocked bios and a good machine.

with 0 volts means no voltage, and if it's already at 0 (gray out doesn't count) then u can't go lower than that i believe thats end of the line.

 

anyone else having the problem that Trottlestop isn't saving settings after Windows reboot?

(at page 442 is my full description)

 

I was hopeing for some more explicit advices , how to set the TS and how to test it . Mby from someone with a 4720 hq and TS 8.1 .

 

@JohnnyR8 - I am not sure if I fully understand your question. ThrottleStop makes changes to your CPU but these changes are temporary. When you exit ThrottleStop, most of the changes you have made will remain unless some other software or Windows changes something. ThrottleStop does not make any permanent changes. It does not change anything in your bios. You will need to run ThrottleStop each time you boot up or each time you resume from stand by.

If the changes you make in ThrottleStop are not being saved correctly, delete the ThrottleStop.INI configuration file and make sure you have read / write privileges where you have the ThrottleStop folder located.

PowerCut is an experimental feature. This is not saved yet and might not be. Enabling PowerCut while booting up or resuming from stand by can cause the CPU to get locked to a high reported power consumption value which might be a problem for a low power U CPU. This probably wouldn't be a problem for something like a 47 Watt CPU.

@raptor04 - Every CPU and every situation is unique. What problems are you having? What are you trying to accomplish? What are you willing to risk? ThrottleStop is not the kind of tool where you just copy someone's settings.

 

@unclewebb Hi . I was hoping for an answer from you , but i didn t want to bother you . I just want to use TS to undervolt my 4720hq to lower the temps a little bit . My temps are about 92 when i stress my cpu . It doesnt throttle if I only stress cpu , but if i stress the gpu in the same time , the will throttle . Like i was saying , i dont want to open it and change the thermal paste because the laptop is kindda new and I have many months of warranty . And I ve read that undervolting its a safe way to lower the temps . what is the worts thing that could happend ?

 

And I know that every cpu and every situation is unique , but I was hoping for some tips on how to do the undervolting . Btw , sorry for my bad english .

 

@raptor04 - Using ThrottleStop to undervolt your CPU should be pretty easy.

1. Click on the FIVR button to open up the Turbo FiVR Control window.
2. At the top, make sure CPU Core is selected.
3. Check Unlock Adjustable Voltage.
4. Leave the Voltage at Default and move the Offset Voltage adjuster to the left to undervolt. A setting of -40.0 mV seems like a good place to start.
5. Click on OK and do some testing. If your CPU is stable then you can try reducing the CPU Voltage further. Using this same method to reduce the CPU Cache voltage a similar amount can also be useful.

Always keep in mind that an Offset Voltage value that works well when the CPU is fully loaded might crash when your laptop is lightly loaded.

A long, long time ago when undervolting a desktop CPU, I went too far and corrupted Windows. I wasted hours trying to recover the mess I made and finally gave up and reinstalled Windows. Undervolting a small amount should be trouble free but always remember that things can and do go wrong. Always be prepared for the worst. I am never as prepared as I should be.

Sorry it took so long to reply. No time for ThrottleStop lately. Too busy overclocking my new Skylake.

 

@unclewebb This is the kind of answer I was hoping for . Thank you very much ! I will start in the morning and see how it goes . That pic is very usefull. And btw , if destroying windows is the worst that could happend when i undervolt , then i don t care . I dont have anything important on this laptop . I was affraid that I could burn cpu or smth .

 

You might be able to burn your CPU if you randomly increased the CPU Offset Voltage. Decreasing the offset voltage should rarely if ever result in any significant long term problems. I think I was using Windows XP when my day playing with the core voltage went horribly wrong. Some people go on wild overclocking and voltage adventures without ever asking, what if something goes wrong. A healthy level of fear is a good thing.

Skylake progress is coming along nicely. The new MHz and multiplier algorithms are much improved and almost ready for further testing.

 

Wow, thanks for the app!
My Wacom Cintiq Companion has super loud fan noise and heating problems. This utility is really helping me stay away from the heat and the noise.
BTW I can't minimize the app to the notification tray icon. Is it by design, or is it just that I couldn't find the right button to push yet?

 

This will minimize it to tray on closing if you don't want it on your taskbar.



Set multiplier not working for me now. I had this problem earlier today and playing with non turbo ratio locking helped. But now it doesn't.

 

Set Multiplier is working correctly on my 4700MQ. Make sure the Non Turbo Ratio is set to 0 and that you are using the Windows High Performance Profile in the Power Options. Multiplier control might not work correctly in the Windows Balanced power profile.

Make sure Task Bar is not checked if you want ThrottleStop to minimize to the system tray. That setting can be found just above the Save button and the Log File option on the main screen.

 

Set multiplier doesn't work. (Though it worked). Non turbo ratio - 1 no matter what I set it, lock or unlock it.
It's all the same on all 3 profiles. Energy saving profile used to keep the multiplier at 8 most of the time CPU was lightly loaded, now it keeps it at 24. Reboot didn't help.
I deleted throttlestop's folder and extracted new one from the archive. Still got the problem.
Furthermore, I had -89/0/0/-107 core and cache voltage offset profiles, now, with the newly extracted TS I have -89/-89/-89/-89 core and cache offsets. GPU changed from 0/0/0/-160 to -125/-125/-125/-125 (BTW is it default? because I remeber having these GPU offsets when I first launched TS).

UPD: after second reboot offsets zeroed.

 

Your screenshot shows that the Non Turbo Ratio is presently at 1 and the register in the CPU that contains this information is now Locked. Once this register is locked, there is no way to unlock it unless you reboot. You may be asking for a setting of 20 but if the CPU is Locked, it is going to ignore this request. Same thing if you change profiles. It doesn't matter what you request, if the CPU is locked, it is locked and this setting cannot be changed.

A Non Turbo Ratio setting of 1 means the Set Multiplier feature will be completely ignored. Sounds like this is working as it should be.

In the FIVR window at the bottom right, there are 3 different options to control how and when the various voltage changes will be saved. Do you fully understand how this feature works? That might be causing some of the voltage saving problems that you are having.

When you first launch ThrottleStop, if it does not find a previous ThrottleStop.INI configuration file, it will read the values that your CPU is presently set to and use those as the default values. If you boot up and your CPU has all of the offset voltages, etc., set to zero and ThrottleStop does not find an INI configuration file, ThrottleStop will use zero as the default values. If you save voltages to the INI configuration file, ThrottleStop will use those values the next time you start ThrottleStop regardless of what settings you might have changed in the bios.

 

First at all I wish to thank you for this amazing tool. But I have one question, the first gen of Core i is fully supported?

I'm seen some really interesting stuff here but only for recent CPUs.

 

I continue experiencing problems with TS that I cannot explain.
After night in hibernation mode I opened TS to see Set Multiplier working and Non Turbo Ratio unlocked and set to 24. I was able to change it in under 24 range. But after switching profiles ( one of them had Non Turbo Ratio - 1 and locked) I got it locked and set to 1 everywhere.
I unticked "lock Non Turbo Ratio" in all 4 profiles and rebooted - stil got Non Turbo Ratio - 1 and locked.
BSOD changing profiles ( having offset that passed all stress tests (AIDA 64, LinX, Prime 95 etc.) except x265.
Reboot.
BSOD on executing TS.
Reboot.
TS opening fine - still got Non Turbo Ratio - 1 and locked.
Hibernation.
TS opening fine - still got Non Turbo Ratio - 1 and locked.

Concerning previous settings changing I'm almost certain I had "save immediately" in FIVR. And I never had offsets in profiles 2 and 3.
By the way, I think that x265 is the best stability test for undervolting. The benchmark can be found here: http://x265.ru/
My system passed many stability tests at -107 mV core voltage offset, but x265 ran stable at -89 and no further.

UPD: got reboots when attempting to execute TS with -107 core/cache and -160 GPU offsets with almost no CPU load (maybe even other profile with 0 offsets was active). So I deleted TS folder once again, unzipped new one. This time offsets were locked and 0 as they should be. -107/-107/-160 core/cache/GPU offsets working stable except graphic artifacts when CPU temperature hits 100C (it happens even with no offsets). Non Turbo Ratio still locked.
What locks it and what can I do about it?

UPD2: profiles 1 and 4 (0 and -107 core voltage offsets respectively) showing same temperatures and power consumption under 100% load by TS Bench (values typical for -107 mV).
http://i68.tinypic.com/300fwhu.png
http://i67.tinypic.com/35a2cfd.png

Using Aida 64 stress test makes temperature and power consumption a bit more but still equal no matter what profile. Turning TS off and exiting change nothing. Do Not Reset FID/VID unchecked.

UPD3: and then after one of the many reboots Non Turbo Multiplier is unlocked and working on power saving windows profile.

The 1st Gen Core i 920XM was one of ThrottleStop's biggest success stories and it still is. Have a look around for 920XM and 940XM world record holders and ThrottleStop is usually involved too. Most of the newer versions of ThrottleStop have been developed to support the newer CPU models so some users with 1st Gen processors seem to stick with TS 6.00. Use whatever version works best for you.

@kzmn - You need to understand that when you switch to a profile that has the Lock feature set on the Non Turbo Ratio, you cannot just switch back to a different profile to unlock it. The locking occurs within the CPU itself. As soon as this happens, you can exit ThrottleStop and the CPU will forever remain locked. Some people want that feature while others need to avoid doing this. I like setting my Non Turbo Ratio to 1 which allows maximum performance and prevents my Lenovo Y510P from disabling Turbo Boost. I just set it to 1 but I do not need to use the Lock option so I leave that alone.

When you reboot, the bios is supposed to reset this register and unlock it. I am quite sure that there are some bios versions out there that do not unlock this register like they are supposed to. If this ever happens, try completely powering down and pull your battery too. Wait a little bit, put the battery in, plug your laptop in and boot up and see what happens. There is nothing I can do about this. Some manufacturers overlook things like this when writing the bios. Windows 10 also has a feature that I am not a fan of where rebooting does not do a full reboot. Here is some more information about that and how to do a full reboot which is more likely to fully reset the CPU.

http://www.tenforums.com/tutorials/7370-restart-computer-windows-10-a.html

In your UPD2 examples, you left out the FIVR monitoring table on the right hand side so I cannot see if the offset voltage was properly applied or not.

The offset voltage values you are using are much more aggressive than what I can run on my 4700MQ. If I tried to run offsets like that, I would get light load BSOD problems almost immediately. When playing with offset voltage, light load testing is just as important as full load testing. I like running a single thread of Prime95 as well as just surfing the net.

The TS - FIVR window has a Zero Offset button. This makes it easy to get back to a setting of zero. Click on that button and then push apply and your CPU will be back to Zero Offset. You will need to do that for each different voltage type. This is a little easier than constantly deleting ThrottleStop.

Edit - One very important thing is that if you are using the Unlock Adjustable Voltage feature in one profile then you should be using this in every profile. If this is checked in your first profile but not checked in your second profile, the voltages you are using in your first profile will continue to be used in your second profile. Not checking that box is telling ThrottleStop to simply ignore the voltage in this profile so it does. If you want zero offset voltage in your second profile then you have to be specific. Check Unlock Adjustable Voltage and use a setting of zero. Watch the monitoring table on the right hand side so you can understand what ThrottleStop is doing to your CPU voltages.

 

Having a very strange CPU wattage problem on my 6560U after going to windows insider build. I don't believe it's related to TS at all, but I am at a loss of what could cause the CPU to take more than 5x the power it usually does- it should be less than 1W at this clock. I've tried setting my BIOS to defaults to no avail. Any ideas what could cause a high CPU package power despite it not being used?

Rolling back to regular Windows build fixed it

 

Thank you for explaining. What are your offsets for 4700 MQ?
So, core offset brings the most effect on power consumption and temperature, cache offset's effect is 4-5 times less, effect of I/O and system agent offset were unnoticeable in my case.
Cannot find much information about VCCIN. Can it be used to add stability and go further with core and cache offsets? Is there much use in it?

 

@Eason - One thing I noticed in your screenshot is that your CPU is not using any of the Package C States. Turning these off will increase power consumption when lightly loaded. Does the regular version of Windows show anything different now?

Edit - Just for comparison, my 4700MQ reports about 1.2 W to 1.3 W when it is idle using the package C6 C State but this increases to about 7.2 W to 7.3 W when the package C States are disabled. Same load.

 

@kzmn - During testing, increasing VCCIN seemed to decrease the reported power consumption. It seems to be a bug in these CPUs. Temperature goes up so you know that power consumption must have gone up but reported power consumption goes down. This trick can be used to get a little more turbo boost before throttling begins. Now that the PowerCut feature is available, it makes more sense to use PowerCut if you are looking to get a little more turbo boost out of one of these CPUs and then you could try decreasing VCCIN to see if that helps reduce core temperatures. Your laptop looks like my laptop where it is thermal limited. Changing out the thermal paste is on the things to do list but I mostly only use this laptop for internet and testing purposes so ultimate performance is not that important.

My CPU core is only good for about -40 mV or -50 mV of offset voltage. Similar for cache. During a TS Bench test, VID voltage is reported as 1.0360 V and it can maintain the full 34.00 multiplier throughout this test. Some CPUs have a higher VID programmed into the chip by Intel so these should be able to use a higher negative offset voltage without becoming unstable. That's why it is kind of pointless to compare CPU settings. We both have the same 4700MQ model number but they are more than a little different. Adjust away. If it is unstable, it needs more voltage.

 

Interesting! Yes, there must be something wrong with that build of windows. Back on the old build and I see C2 and C3 of the package C state percent. are being used. C6 and C7 are not, though.

 

Hi @unclewebb, thank you for creating Throttlestop. I have been using it since the very beginning.

Today I have a bug with Surface Pro 4 and ThrottleStop 8.10.

According to figures reported by throttlestop, I noticed that the package power of the cpu (i5-6300u) always is capped to around 7.5-8.0w regardless of number of core usage, temperature, voltage. It doesn't seem like there is any throttling and max load temperature is below 50 degrees Celsius. The maximum CPU frequency I was able to obtain while running any workload is 2.9Ghz for 1 core (unable to achieve 3.0Ghz), 2.6Ghz for 2-4 cores.

I have tried to test undervolting using FIVR. On my surface pro 4, the voltageID in the main application does not respond to undervolting attempts. I tried to undervolt 50, 100, 150mV with ease and stable under any kind of load. The VoltageID remained the same. It is stable both idle and under load. I tried to test a crazy undervolt (250mV) to see if the CPU truly undervolted. The result is the OS hanged (expected).

I have been using throttlestop on Surface Pro 3 and as far as I know, it also works on surface pro 4. What could I have done wrong or is my Surface Pro 4 some how special. I am open to any troubleshooting/debugging on my end.

Update: After a restart, the capped TDP went up to 10W and VoltageID display is able to respond to voltage undervolting changes inside FIVR.

 

@jackluo922 - The Core i5-6300U uses a Configurable TDP Down (cTDP) mode. When a low power U CPU is forced into one of these modes, it will be limited to 7.5 Watts or 10 Watts or whatever a manufacturer chooses. The ThrottleStop TPL Window should show what modes your CPU supports. Here is an article that talks about this feature.

http://www.cnx-software.com/2015/08...s-7-5w-tdp-a-closer-look-at-configurable-tdp/

I have heard that uninstalling the Intel Dynamic Platform & Thermal Framework Driver might give you more control of your CPU but I do not have any hands on experience with a Surface Pro 4 to test this out. You might be able to leave that driver installed and then make changes in the Windows - Power Options as that article shows.

With the 6th Gen CPUs, I think you need to adjust the CPU Core and CPU Cache voltage in tandem when using ThrottleStop. After I do some testing, I will probably change ThrottleStop so users are forced to adjust both of these at the same time. With previous Broadwell and Haswell CPUs, these two voltages could be adjusted independently. Post some pics if you have some more questions. I always learn something new when I see some screenshots of ThrottleStop in action, especially on hardware that I do not own.
