The ThrottleStop Guide

actually i still prefer throttlestop over xtu because it's much faster to change profiles and set them up or play with some tuning.

I don't know where I can set Icc in throttlestop but I set everything in the TPL tab at max value hoping that current could be there too.

From bios instead I set Icc max from voltage regulation line which clearly states it's Icc. Although this doesn't work at all. I didn't work even with throttlestop disabled (hoping I didn't do anything wrong).

Instead, as soon as I installed xtu and raised Icc from its menu, current throttling stopped and I could finally start to fry my 7820HK

 

I beg for your pardon. I seriously admire your work with throttlestop.

Cache limits work ok but if I set Max limit higher than 36 it still doesn't go further. Lower limits are clearly working ok.

I can get multipliers over 36x by setting the fixed ratio although if you try to set a different ratio for each profile only your last submission will be considered and applied to all profiles you set at fixed cache multi.
Yes, cache voltage was always set to adjustable.

actually, is there an easy way to give you small donations through credit card?

 

I also prefer TS over XTU.

Icc is "PP0 Current Limit" in Throttlestop, but I know not whether this value works for Skylake and Kaby Lake. You would need to put in 256 or higher manually.

I don't have Icc in my BIOS, I flat out have current limit. So I am not sure what is up with your system in that regard.

 

will try again tomorrow and I'll look at that TS entry you suggested. I will report back after. I'm not 100% what trial I did with the PP0.

One thing I wonder though is: What units of measure are used by throttlestop? Standard S.I.? Or bios units? ...because bios current is set in 1/4A in my case so I would need to set a 1000 to get 250A for example.

 

TS is straight value. Also my bios is 1/8 current limit, not sure how you are 1/4... I guess OBSIDIAN's BIOS tweaks?

it's either I remember it wrong or it might be john's fault :d ...this is my first clevo so I don't know how's the standard bios

 

If you remember it wrong and set it for 1/4 then it makes sense.

that's true. I'll check tomorrow hoping I have some spare time to play with it.

beaware coconuts might break smartphones

 

It's my power source. Caribbean island and stuff.

mine could be beer then. It's also pretty easy to find anywhere.

 

Thanks for the info. Returning the Minimum processor state to 100% seems to let TS take over. So my follow up question is for better battery life when my laptop is unplugged, should I keep the Minimum processor state as 100% and use TS to control it, or switch the power profile to the Power saver instead?

 

Thank you it has worked

 

Btw, I don't have any checkbox in the PP0 Current Limit entry. I can only check the "Lock" and set the number value. But by doing that i achieve nothing and current throttling is still there.

Also I still have to understand how power limits within throttle stop work because it looks like only BIOS power limits apply correctly. Will do more trials as soon as i can.

 

On my Dell XPS 9550 (6300HQ), ThrottleStop (TPL screen) does not seem to fully access the "package power limits" registers. It might work perfectly on your system.

My workaround to adjust package power limits:

- Open up XTU 1 time only and made the adjustments there (PP long, PP Short, Turbo time limits)

- Make sure the same adjustments are in ThrottleStop's TPL window

XTU has a great looking interface. But it has been a problematic piece of software so I try to avoid it. Issues included: randomly changing settings or losing settings.

Also, do not run XTU and ThrottleStop at the same time. They will conflict as they try to write the same registers.

I use ThrottleStop daily for: undervolt, SpeedShift, and the superb C1E switch.

 

I'm having PL1 issues as well and am not sure how to raise the power limit

I can set power limits from bios easily. The only issue is about Icc, which i can also set from bios but it doesn't seem to work properly. I would really prefer to avoid using XTU.

I'll probably wait for a Throttlestop or bios update. Or even prema bios.

 

I don´t know why but since V8.40 is not allowing me to see the temperatures and the Core Speed on the task bar. when i go to options it doesn´t allow me to check the boxes

 

A question to those using Task Scheduler to start TS at startup: everytime Task Scheduler starts up TS at log in, TS does not appear in the taskbar/window or notification. However a check of Task Manager shows the process running in the background. Only when manually launching the app then will the icon/window appear

 

Main window: task bar uncheck
Option window: start minimized check
Minimize on close check
No icon in task bar tray uncheck

If not working, clear the icon tray cache using the instructions provided in the ThrottleStop folder. (I think it's a web browser URL)

Edit: also, make sure the task is initiated at login, not with Windows.

@leader288 - Double check the task you created with this tutorial.

http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/page-514

@John Hito - Any icon related issues can almost always be solved by cleaning the Windows icon cache.

http://www.digitalcitizen.life/how-clean-notification-area-icon-cache

@-BaTaB- I will have a look this week to see where IccMax is hiding. Some Intel settings are duplicated and unfortunately, ThrottleStop cannot get to all of them.

 

I'm having the same problem. I get no tray icons at all with the newer versions and it won't let me check the boxes for cpu temp, etc.

The "no notification area" box is unchecked and the taskbar box is unchecked. It either runs in the taskbar only or closes.

 

I had a chance to play with the cache ratio on my 4700MQ. The way it works is a little confusing but I think it is working correctly.

The Cache Ratio slider at the bottom middle of the FIVR window can only be used to increase the cache ratio higher than the default setting. My 4700MQ uses a default cache ratio of 34 so setting this to Default gets me 34. Any setting between 8 and 34 is ignored. A setting of 35 gets me the 35 cache ratio and a setting of 36 gets me the maximum 36 cache ratio. This CPU only supports +2 bins of overclocking.

If you want a maximum cache ratio less than 34, you need to use the separate Cache Ratio Minimum / Maximum setting which is just below the monitoring panel in the FIVR window. For a maximum of 28, just set the maximum to 28. ThrottleStop can save different Min Max values for each profile so give this a try. It should work.

I agree that this is a little confusing but I blame Intel. They created 2 separate registers to control the cache ratio which is not necessary.

@JohnnyFlash - Did you clean your Windows icon cache? As soon as you do that, it is usually problem solved. After you do that, do not run different versions of ThrottleStop from different folders. Use one folder for ThrottleStop and keep it in the same location. Any changes and you will need to do another cleaning.

 

I also found this post on another board: https://www.techinferno.com/index.p...xperiences-version-20/&page=104#comment-70524
The user kaladeth not only got a 2860QM working, he also successfully got an eGPU setup working. Interesting stuff. So it looks like an upgrade is possible, despite the official position of HP being otherwise. Now to save my precious pennies. Thanks for the input.

 

Understood...that's quite bad.
I saw your post under
http://askubuntu.com/questions/337147/throttlestop-for-ubuntu
Do you think that looking at what TS does under Windows is a viable way of learning it? I could do this, but sadly only on Haswell...

 

Understood. Although what i was wondering are two other things:
- is it intended that when you set different fixed cache ratios for different profiles, throttlestop lets you do that but once you apply the setting, throttlestop will apply only the last value you set on all the profiles you set to "fixed cache ratio"? For example you set profile one to 40x, profile 2 to 45x, profile 3 to default and profile 4 to 36x leads you to all profiles set at 36x after you click apply.
- fixed cache ratio is only working for multipliers that higher than default but how about the Min/Max? Is it intended that you can set Max at ratios higher than default but the real multiplier will never go higher than the default? I see that only fixed cache ratio will let you have a multiplier higher than the default setting.

 

After reading this, does this mean there is no way to launch TS unhidden using an admin account & task scheduler, when a non-admin logs on?

 

Now I understand what you are talking about. When using ThrottleStop, I have always just set the Fixed Cache Ratio to its maximum value for all profiles and then if I wanted a lower value, I set that by adjusting the Cache Min / Max to a lower value. I also tend to only use a single profile so I never noticed the bug with the fixed cache ratio changing randomly in the FIVR window when changing profiles. I will get that fixed up so it works properly in the next release and thanks for bringing that to my attention.

Instead of thinking that the cache ratio slider is a fixed cache ratio slider, think of it more as a slider to control cache overclocking. You only need to use this slider if you want to access cache ratios greater than the default cache ratio. When you set this slider, it has to be in agreement with the Min Max Cache ratio that you have set. The CPU will check both values to determine what cache ratio it is going to use. For example, you can set the slider to access an overclock cache ratio but if you set the Min Max cache ratio values to a lower number, the Min Max is going to win so the CPU will use the Min Max ratio. Likewise, if you set the cache ratio overclock slider to its default position, the CPU will ignore your Min Max cache values if you have set them higher than the default value. Once I get this feature fixed up, you can do some testing and hopefully it will make more sense.

@JerryDD - You can try to learn about how the FIVR works by comparing registers to settings in ThrottleStop. When doing this, make sure you are only using ThrottleStop and do not use any other monitoring programs or Intel XTU at the same time. Even programs that do not let you adjust the voltage are still using the overclocking mailbox to read voltage and offset data from. Haswell, Broadwell, Skylake and Kaby Lake all work pretty much the same. Good luck.

@leader288 - ThrottleStop is not very user friendly when trying to use it in multiple accounts. It was originally designed so a single user could tweak their computer and go play some games. If you need to be able to make adjustments across multiple accounts then you will probably be better off using Intel XTU.

 

Alright, now it's crystal clear. Thanks a lot.
Do you think Icc max for kaby lake will be available in some future release of TS?

 

Thanks unclewebb. I need some more thinking on whether it's worthwhile to jump in...

 

This adjustment will not likely be in ThrottleStop anytime soon. I know that Intel has moved this into their overclocking mailbox but I do not have access to any documentation that shows how to access the individual Icc Max values. If your CPU is throttling at full load and EDP is lighting up in red in Limit Reasons, you will either need an unlocked bios or you will have to use Intel XTU to increase Icc Max.

 

That's the exact reason . I was hoping for your TS since XTU is kinda garbage in comparison. No offense to Intel but I think that's the truth.

I guess I will hope for the kind @John@OBSIDIAN-PC to fix the Icc bios setting or even the Prema boss unlocked bios .

 

We just got a great coder to work with us on the app so there will be great stuff coming for everyone.
But for more TS features read this: http://forum.notebookreview.com/thr...y-by-obsidian-pc.801464/page-29#post-10501272
Some donations for uncleweb would be a great incentive for him to keep adding requested features

Will do will do. I don't have a paypal account. Need to gather info and register

 

Just found the culprit for audiodg.exe using .5% UC utilization even while muted. I tried disabling audio related stuff, and disabling the microphone dropped it to zero. Then I remember I had "hey cortana" active.

Very Good tools, thanks

 

Thank you for this program UncleWebb, it's very useful and informative! However, I have a throttling problem that doesn't quite seem to match any others I've encountered after a fair bit of research, can I post about it here?

 

I guess it depends if it's related to ThrottleStop, but I guess you might be in nice place to ask.

 

Post away. The more info the better. Is anything lighting up in red in Limit Reasons if your CPU supports that program? I always like hearing about new problems or new throttling schemes.

 

I just realised something - the U power CPUs' are not necessarily limited to 18.6W for me.

Without fiddling with CPU registers in RW-Everything, my CPU will happily use up to 22W of power when performing the LinX Benchmarks - No power limit throttling. This is without undervolting. My i7-6500U was at full 3.0GHz for the entire session of the LinX,

BUT... on the 4th or 5th run of the 2048MB Problem Size, thanks to LinX for letting me see the first thermal throttling on any of my laptops in 5 years - CPU got up to 95C before underclocking due to PROCHOT and thermal limits

Recap:
The Integrated GPU was NOT loaded during LinX
If the CPU Cores alone are causing the power consumption to go above 18W, the Core speed will not throttle.
Testing again, if running the AIDA Stress Benchmark, which stresses the Core as well as the integrated graphics card, the entire package throttles itself to 18W.


Let's test this on my older Acer Aspire E15-571PG-524H:

Running LinX: The CPU uses 23W, and does not throttle for the entire duration of the benchmark.
The integrated GPU was NOT loaded.

Again, running the AIDA Stress Test with the Core and iGPU loaded results in the entire CPU Package getting throttled down to 18W

So I can assume Acer isn't willing to throttle their CPUs much.

It is the same with their dedicated GPUs, I've seem some gaming laptops manufacturers that temperature limit their dGPUs to about 70C, whereas Acer locks the 840M and 945M on both of my computers to 92C. Why does this matter? Because it sets the parameters for Nvidia GPU Boost

The Nvidia GPU Boost basically automatically "overclocks" the graphics card based on the temperature limits the manufacturer sets. For other laptops, if the temperature limit is 70C, the GPU will boost all the time until it reaches 70C, at which time it will reduce its clock speed to the base clock to try to keep inline with the 70C temp limit.

No wonder my dedicated GPUs were running at their boost clocks all the time.

 

Alright, thanks! I've got an Asus X556U with a 7th-gen Core i5 7200U overclocked to 3.1Ghz, and an Nvidia Geforce 940mx. I use it mostly for internet browsing and gaming, and occasionally I experience a brief but massive performance drop seemingly regardless of how computationally intensive my current activity is. Here's some logfiles taken during several of these events, from simply having a lot of tabs open in Chrome to testing the game War Thunder with high graphics settings: https://pastebin.com/0RiFXQPJ https://pastebin.com/kv8XFQ4W https://pastebin.com/t3wXtteC

Core and GPU light up solid red PL1 in Limit Reasons when the voltage drop occurs. and BD PROCHOT and PL1 are solid yellow all the time (even when I have BD PROCHOT unchecked); EDP OTHER is yellow under RING. At the same time as PL1 goes red, in the logfiles you can see that the MULTI and POWER entries bottom out and PL1 is recorded.

I've been perusing this thread and some others dissecting similar issues and tried a few settings changes in ThrottleStop but nothing's helped, here's my current settings.

 

Thank you for giving my Laptop a last chance. The main feature was only one: DTS in a second Profile, as you recommended in thermal issues with Sandy Bridge. The GPU issues I stopped by brute force with all frequencies set to 50%, but then the machine is nearly unusable but survives GPU temps over 90°C..

 

Along this thread of work I learned a lot about the inside of a laptop, very interesting.

 

Have you tried stressing the CPU only? With ThrottleStop TS Bench or some kind of CPU stress test?

Che0063's post just above yours show that the GPU is limiting the CPU in some way, so that could explain why it throttles even tho it isn't doing much.

PS: overclocking is pushing a CPU beyond its specified max clock speed, settling it so it stays at said max clock speed is not overclocking

Also, UncleWebb did some digging with a 7500U

My Laptop is now the age to go in thermal issues, ThrottleStop only will prolong his life to control his thermal behaviour, Yes there is PROCHÖT that sends signals to CPU to throttle in case of GPU´s overheat situation that throttles CPU from GPU without Termal throttling situation of itself. The aim is to cool down the total set, so GPU could recool itself.

 

@unclewebb Look what I found on Notebookcheck.net today? ThrottleStop reviewed Again, thanks for making this wonderful tool.

"ThrottleStop is one of the most useful programs for any PC user, but it can be intimidating to use at first glance. This primer walks readers through installing ThrottleStop, explains its basic features and functions, and guides them through some basic optimizations that any user could benefit from."



"ThrottleStop, an original program by “ @unclewebb ", started as a simple means to counteract some throttling mechanisms used in older laptops, check temperatures, and change CPU clock speeds. Over the years, ThrottleStop has been tirelessly updated by its creator and has now collected quite an array of extremely useful features not just for avoiding throttling and overheating, but for increasing the performance, battery life, and functionality."

 

Thanks for posting lots of pics and log file data. After looking at your logs, I headed to the Asus website to learn more about the X556U and the first thing I read was, "Uncompromising Performance". Really Asus? Looks like the marketing department and the engineering team are living on two different planets. The performance of your i5-7200U in your laptop is nothing short of a disaster and sadly, it appears to be by design. If I bought this laptop I would immediately be boxing it up and heading back to the store looking for a full refund.

Let's start with the Intel specs.

http://ark.intel.com/products/95443/Intel-Core-i5-7200U-Processor-3M-Cache-up-to-3_10-GHz?q=7200u

The Intel specified thermal throttling temperature for a 7200U is 100°C but if you look at ThrottleStop, it shows that Asus decided that was too high so they dropped that down to 90°C. When a check mark appears in the ThrottleStop PROCHOT box, that shows that your CPU has been doing some thermal throttling.

That first problem is mildly irritating. The next problem is that Intel's low power U CPUs are kind of like 3 CPUs in one with 3 significantly different personality and performance traits. By default, the 7200U is a 15 Watt CPU but it also has 2 different TDP levels that it can operate at. TDP Level 2 allows the CPU to operate at full speed up to the 25 Watt level. That's wonderful and easily enough for full performance but manufacturers are not required to use that level. TDP Level 1 is also known as Configurable TDP Down and when the CPU goes into this level, it turns your CPU into a low power CPU with a TDP rating of only 7.5 Watts.

That's bad but it gets worse. Each TDP Level is also associated with a different default multiplier. I think the default 15 Watt TDP Level has a default multiplier of 25. The TDP Up level has a default multiplier of 27. ThrottleStop shows that the TDP Down level has a default multiplier of 8. That's really bad but it looks like your CPU is taking this misery one step further and it is dropping down to the minimum multiplier which is only 4. A 400 MHz CPU is a far, far cry from the 3100 MHz CPU that you thought you purchased. Your CPU seems to be entering TDP Down mode and is then getting stuck there for excessive amounts of time.

I do not fully understand what triggers the CPU to drop down into TDP Down mode. The algorithm might be some sort of time weighted average so if it runs at a high TDP level for too long, then it is forced into TDP Down mode. This happens instantly. It is sort of like a little kid that gets a time out and has to go and sit in the corner until he cools off. After that, it tries to get back up to full speed and then ends up throttling again and again.

I know of 2 registers, one in the CPU and one in the memory mapped IO which can be used to lock the CPU into TDP Up mode or even the TDP normal mode but I am pretty sure that there is a third register that I cannot get to that controls the TDP Level. If this cannot be controlled then the only remaining option is for you to reduce power consumption and try to prevent the CPU from ever going into TDP Down mode. I would start by under volting both the CPU Core and CPU Cache by approximately -100 mV. This can make a significant difference. The next thing you might have to do is use the ThrottleStop Disable Turbo option. This will slow down your CPU which is a bad thing but compared to dropping off a cliff and getting stuck at 400 MHz, no turbo boost is not that bad.

I feel your frustration, especially after watching the 7500U I bought run all 4 threads happily at a steady 3500 MHz without a hint of throttling. That taught me that there is nothing fundamentally wrong with Intel's low power U CPUs. The problem is manufacturers that have lost their minds. What sort of person, pretending to be an engineer, thinks that a modern CPU, in 2017, stumbling along at 400 MHz is acceptable? That kind of stupidity leaves me speechless.

Could you try upgrading to the latest version of ThrottleStop? It is not going to solve your throttling problem but I think the latest version does a better job of accurately reporting the CPU multiplier and BCLK speed on the 7th Gen U CPUs. After you do that, open up the Turbo Power Limits window, check the TDP Level Control and set that to 1. For a test, go back out to the main screen and click on Disable Turbo. What sort of multiplier is reported? This test usually shows 8 but with your CPU, it might only be 4. You can try that test too with TDP Level set to 0 and to 2. I am mostly just curious. Just trying to see what sort of control TS has over your TDP Level. After this, with this set to 0 or 2, go try to play a game and see what happens. I am not expecting this adjustment to make any long term difference. When this U wants to throttle, it is going to throttle. After that you can try various settings to reduce performance to try and avoid the dreaded TDP Level 1 wasteland. You should also be able to reduce maximum performance by lowering the Misc - Speed Shift maximum multiplier setting.

Hopefully some under volting will make a significant difference. If you talk to Asus, tell them to get their heads out of their back sides. Show them my screenshots of how a 7500U can run. 400 MHz might have been OK back when Windows 95 or Windows 98 were popular but 400 MHz is an unacceptable speed for a laptop to be running at in 2017.

Thanks @Papusan - Always nice when others notice the usefulness of ThrottleStop.

 

As I have always have said... INFO OUT TO THE PEOPLE Importent!!
