The ThrottleStop Guide

Thanks, UncleWebb - what a nice Christmas present!
Joe

 

Just a question can I just copy the old ini to transfer my settings I always entered all values again manually since the ini might be changed but is it okay?

 

Hello & Mery Xmas. Is there a way to setup TS as a Windows service, so all accounts can benefit (especially non-admin ones). I presume the answer to be 'no', but no harm in double-checking.

 

Anyone tried running throttlestop on linux with wine? I'm using https://github.com/georgewhewell/undervolt But this has only few options. It'd be great to have all the features even on linux.

 

Really loving the view of all 12 threads from the 8750H!

I think in Task Scheduler you can set ThrottleStop to "Run whether user is logged on or not" which may be the solution?

 

Good point. I'm not sure if this would work given that this is a UI application. Worth having a go. Will report back.

Edit: apparently this will cause the UI to be suppressed, which I would be fine with as long as TS is still running in background and doing its thing.

In general, new ThrottleStop versions are backwards compatible with previous versions. Just copy the new ThrottleStop.exe into your existing ThrottleStop folder and it will use all of your previous settings. When I add a new feature or new INI option, the new option will automatically be added to your previous INI file.

I agree. It took me a while to get this working correctly. This feature automatically adjusts depending on whether you have 10, 12, 16 or 20 threads.

@etern4l - A person in this forum a long time ago used this method to run TS as a service.
https://github.com/rozanski/srvstart

If you use the Task Scheduler option to start ThrottleStop before a user logs in, this should work correctly. There will be no access to the UI though. Run HWiNFO and make sure that TS is applying the voltages appropriately. Turn off the system tray icons since they will not be available when TS starts before you log in.

 

Hello,
I recently bought a Matebook x pro 2020 (i7-10510U) 16Gb, and followed guidelines shared on this forum.
Thanks to that, I managed to modify the BIOS (1.12 and then 1.15), to unlock what is called "overclocking lock" in the Huawei BIOS,which allows ThrottleStop to undervolt CPU.
I then applied parameters proposed by @fanlessfan: -218mV for CPU core and -50mV for the other parts worked well for me.

Thanks to it, my laptop has become amazingly silent and cool when running desktop applications, whereas cooling fan had been on most of the time prior to that. Battery life is extended and charging while using the laptop has gotten much faster (as the laptop remains cool). It's below 40°C as I'm writting this post.

This by itself is a great achievement and I'm very gratefull to people sharing their experience here.

The less good news is that performance improvement was rather limited (Geekbench test). In fact it stay between 3100 and 3500 in multicore most of the time.
I played with the Turbo boost options in TPL after having checked "disable and lock turbo power limits" in FIVR but whatever I do, package power caps at 15W. I guess this is the reason why performance has not increased much. With a TS Bench 96M, 8 threads, fan does not even start with temperature getting close to 90°C. No thermal throttlig occurs. Only Power throttling.

So I wonder what I missed that would make it possible to break through the 15W limitation as I could see on pictures reported by @fanlessfan. Is it linked to TS parameter? is it windows or another bios tweak? Is it possible that it works with some MBX pro 2020 and does not work with others?

Thanks for you help.

 

Some manufacturers use firmware that forces the long term 15W TDP limit. No easy way around this limitation. If you had access to the IMON Slope setting in the BIOS, you could adjust this. This can be used to trick the CPU into reporting less than the actual power consumption. I have never personally done this so try doing a Google search and maybe you will find some more info. You can also try searching this thread for IMON Slope.

Try ThrottleStop 9.2.9. It is available at TechPowerUp. Check the FIVR Disable and Lock setting and set the turbo power limits in the TPL window to 25 long and 25 short. Try using the Turbo Boost Power Limits - Lock option. If you are still seeing power limit throttling at 15W then there is nothing ThrottleStop can do to help you get beyond this limit.

 

Hi unclewebb,
Thanks again for your help
I made the tests that you recommend, using TS 9.2.9. Result is that with both Turbo Boost Power limits locked at 25W, I'm still stuck at 15W.
I wish I knew what fanlessfan did to overcome that issue.
@fanlessfan, it would be so nice if you could share how you made it !

I also looked for ways to change IMON slope parameters, I could not find a solution for the matebook x pro. It's a shame as there may be a way. Actually searching for "IMON slope" within the bios code after having extracted it, I could find "IMON slope" string in there, with its current value. It may be one byte to change to make it work in the end, like for unlocking undervoltage. But how to ne sure?
Also, it seems the bios contains all the code that goes with a a "overclocking performance menu" and that allows to change multiple parameters related to CPU and memory (Insyde H2O v5.0 bios). Unfortunately that menu is hidden and the multiple key sequences that I could find on google to unlock that menu on other computer brands do no work on the matebook x pro...
It seems here is the end of the road..for the moment....

Anyway, it's already a good acheivement to have this already great laptop getting better thanks to TS!

 

Works a treat. Didn't have to turn tray icons off explicitly. The UI is completely suppressed. The non-interactive mode can be enabled even after a user logs in (via Task Scheduler). This is useful if any adjustments of settings are needed - one can just turn the TS task off, launch TS GUI, update settings, close TS, turn the task back on. Many thanks @unclewebb.

 

Hello mate.
There might be a solution for you, if you're sure about dumping/flashing BIOS etc. you might be interested about WIN-RAID forum.
Just ask people arround unlocking BIOS in your laptop, I done that a year ago with my Acer Helios 300 and I had everything unlocked withing few minutes
They will instruct you how to make a proper BIOS dump etc.
You need to be aware that some options might not work / dummy strings etc. but functions like IMON should be there and work after editing value.

 

I have decided to put the Turbo Power Limits window on an after Christmas diet.
I found a little bit of extra room for a long awaited new feature.

 

A quick question. The turbo boost power limit varies between which limits? 0 to which value!?

 

@unclewebb,
Thanks for the new 10 cores version, the AVX feature.. Me and @Justin Stuever been using it on 51M R2 and are facing the same issue. He is using Beta 9.2.9 and i am using 9.2.

We are both on the 10900K and he was reporting to me that if he sets his cores at 48X (for example) that our system will report 1 less bin (47X) under stress (HWinfo monitor and ThrottleStop monitor in CBR20). He thinks it is related to ThermalVelocityBoost. I personnaly have not experience this issue for the first 5 days, except today it started doing the same thing. I closed ThrottleStop and reopened it and the problem was still there. I then rebooted and reset my bios to default. Everything was back to normal after that.

I am just reporting this minor issue hoping it will help development. Also when the situation happened to me i noticed that ThrottleStop monitor seems to misread the clock compare to HWinfo under idle.
47x all cores on HWinfo at idle and 43x 46x 45x in ThrottleStop at idle.

Seems like a conflict between software but i am no expert. Alienware command center is a very buggy software so i would suspect it is causing this issue.

 

My screenshot above shows the maximum turbo power limit value, 4095. If you want to get technical, the register can hold a maximum value of 4095.875 but I decided to round that value off. If you have 4000+ Watts going through your CPU, you have bigger things to worry about.

For Intel's 10 core CPUs, only use ThrottleStop 9.2.9. None of the previous versions properly support the 10 core CPUs.

Before I can answer any questions, I need to see as many screenshots as possible of exactly how you have TS 9.2.9 setup.

I have not played with the Thermal Velocity Boost feature yet. It seems like one of those gimmicky kind of features that some marketing department dreamed up.

ThrottleStop 9.2.9 gives me full control of my 10850K. When properly setup, I can run this CPU at any speed I want. It will maintain this speed throughout a Cinebench R20 run with zero throttling. It only throttles a hair when I push it to 5.2 GHz and it hits 100°C towards the end of a test. The 10850K is a crappy 10900K that needs lots of voltage at these speeds so some thermal throttling when pushing it to the brink can be expected.

I love HWiNFO but when it comes to the CPU multiplier, I would trust what ThrottleStop is showing you before I would trust anything else. The monitoring method that most software uses is not accurate when a CPU is lightly loaded. ThrottleStop uses high performance timers within the CPU and is extremely accurate regardless of load. If ThrottleStop shows the multipliers dropping down when lightly loaded, this really is happening. If you do not want this to happen, you need to set ThrottleStop up correctly.

Here is an example of my 10850K when set to the 50 multiplier. Every core has at least 1 thread reporting the full 50.00 multiplier even when some cores are close to 100% idle.

How is he doing this? If you want the 48 multiplier when up to 10 cores are active, the FIVR - Turbo Groups window should look like this.



You should also check the FIVR Disable and Lock Turbo Power Limits box. There are some Comet Lake tricks hiding within that feature.

I would delete any software that is buggy. I know that when ThrottleStop is the only program monitoring and in full control of one of these CPUs, it does a great job. By itself, it is very consistent. I have no idea what kind of bugs might result if you have multiple programs all writing different data to the same CPU registers.

Thanks for the feedback. Include my name @unclewebb in your Alienware discussion if you want my input on what ThrottleStop is showing you.

 

Hello,
Unclewebb is it possible to get rid of the logo and always get the long core list for example

Most cpus have high cores by now. Maybe you can even skip adding an option and just if the logo.png isnt in place it could automaticly do this.
Just a recommendation. Thanks for everything.

 

@berkkocaturk - I agree that ThrottleStop is quite popular on the 6 core - 12 thread mobile CPUs. A layout that targets those versions is a good idea.

I added the reporting of Thermal Velocity Boost (TVB) throttling to Limit Reasons tonight. Of course Intel does not document this so I had to use RW Everything to hunt down the bit that gets set when this type of throttling is in progress. This new feature seems to work great.

 

And now maybe you can hunt bit that also do the trick and disable this limit reason?
Long time ago I write you about TVB but than you didn't had 10th gen or cpu that supports it. I didn't also. But I had 8565u that in theory support TVB but only with plus 100mhz but never seen it trigered.
On 10875h I can see TVB is functional as max 1 core is x49 but i can see it reaches x51 multiplier.

But maybe there is a way to hold it by disabling by some way its limit reasons.

For laptop users it might be beneficial.

 

I found out how to turn off Thermal Velocity Boost throttling. Intel markets this as a boost feature but to me it looks like a throttling feature. When the CPU gets hot, TVB forces the CPU to slow down. That smells like throttling to me.

I added the ability to toggle this feature on and off in ThrottleStop but only for the K series CPUs. I did not know that the 8565U also uses TVB. I will need to re-design this new feature so TVB can be toggled on or off for all processors that support it.

I posted the testing I did on the Alienware forum.
http://forum.notebookreview.com/thr...2-owners-lounge.832848/page-246#post-11067432

 

Seems Intel 8th-gen “H” chips do not have the TVB feature. At least not the 8750H.

Do 9th-gen chips; or was this only included with 10th-gen or later?

 

@unclewebb, @Papusan, @Mr. Fox, and all my other NBR online friends, new and old.

I wish everyone a Safe, Prosperous, and Happy New Year! See you on the other side in 2021!

 

The scam come with the 8th gen BGA Jokes and still live its disgusting life inside the 10th gen Intel Mobile chips. A useless feature added only to be able to charge more.

Same for you bro Tiller. Happy New Year to you all

 

You know what's not a scam? Seeing as you always love to hate on intel. Their 11th Gen Tiger lake CPU's if TVB is a scam how come my i7 1185G7 can sustain the all core turbo indefinitely in my MSI Stealth 15m?

PS I don't think TS works completely with the 11 gen series yet, lots of options are greyed out. Only thing I'd be interested in doing with TS is raising the power limits as that's the limiting factor on my notebook, not the thermals.

 

If it wasn't for TS this i9-10900K would be completely broken in the Alienware 51M. This feature is unwanted. And the notebook manufactures will use it for all its worth to destroy their machines. Why should they follow Intels specsif they can use it as a second or third Throttling mecanism?



See also @unclewebb comment on this useless feature... http://forum.notebookreview.com/thr...2-owners-lounge.832848/page-245#post-11067417

"If HWiNFO is showing Thermal Velocity Boost as the reason for throttling when this happens, then this is what is causing the problem. I have a desktop board with an option in the BIOS to disable TVB. I cannot think of any reason why I would want this feature so I have left it disabled. I will think about adding a red box to Limit Reasons that shows TVB when this type of throttling happens"

http://forum.notebookreview.com/thr...2-owners-lounge.832848/page-247#post-11067583

"I added Thermal Velocity Boost (TVB) to the Limit Reasons window so you will be able to use ThrottleStop to track this type of throttling. Better yet, use ThrottleStop to disable this type of throttling"

Intel Thermal Velocity Boost vs Turbo Boost

Single-Core Thermal Velocity Boost takes the faster of the two favored CPU cores to a speed higher than what’s achieved with Turbo Boost Max 3.0.

For 10th Gen desktop CPUs, this is only doable if the CPU is running under 70 degrees Celsius (158 degrees Fahrenheit) and if the CPU is working beneath its power, current and temperature specifications. For 10th Gen mobile CPUs, the temperature threshold is 65 degrees Celsius (149 degrees Fahrenheit).

All-Core Thermal Velocity Boost refers to the speed achievable if every core is active and the CPU is operating under its respective temperature threshold ( 70 degrees Celsius for desktop chips, 65 degrees Celsius for mobile ones).

 

No thermal throttling here......only power limit throttling.

 

Pasmark is a useless benchmark test. Read about it here http://forum.notebookreview.com/thr...-owners-lounge.797128/page-1124#post-11051630


And be you sure. The notebook Manufacturers will milk on this and similar features for all it's worth. And this won't gain the buyers. Again. A useless feature that should have gone in the grave before birth. This have nothing to do if I like Intel or not.

How Dell cripple performance explained by....

I just don't like that the processor behave like this....

 

So passmark maxes out the CPU and GPU and you don't like it because i'm proving you wrong? I'm not using it as a benchmark i'm using it to stress test the system.

Watch this and cry me a river





Can you explain to me where the CPU clock is going up and down because it's not. It sits at 48w indefinitely at is 4.2ghz forever so what's up and down about that?

 

Your laptops CB R20 score is excellent I am not even getting throttled much because all i can do is hover around 3.9GHZ on all cores which gives me 2900 ish scores your cpu just undervolts like a champ mine is core -210 cache -130 I can not go beyond that do you have other bios etc settings? or is it just good silicone

 

First thing.
You should put the link for TS 9.2.9.2 also here besides Alienware forum as this is main thread.
Second thing
Does TVB setting in FIVR is now applicable to all cpus from 8th gen and up?
And is it possible to control temp value that limits the TVB?
Third thing
Why profiles in TPL are greyed in 9.2.9.2? I MISSED SOMETHING? OR I need to delete ini file?
Fourth thing
Did you change how the bclk is reported? As on 8565u before on TS 9.2 it was 99.767 or something like this, now it is reported as full 100?

Update for 10th gen 10875H CPU and TVB FIVR OPTION.
By default there was a tick near the TVB option in FIVR window and while my cpu was boosting to 51 multiplier many times in limit reasons TVB was triggered first in yellow and also in red.
I had score of around 7.5 in 120 bench.
After I untick TVB in FIVR my cpu is still boosting to 51 multiplier but TVB limit reason did not trigered any way (no yellow/no red TVB LIMIT) and my TS bench 120 went down to 7.32

LOVE YOU

 

Try running CB R20 in ‘Realtime’ thru Task Manager for some extra points. It may freeze the animation, but will complete if the system is stable.
I do believe this particular chip is good, but there is definitely a point of diminishing returns on every chip that has to be found. I usually see around ~0.975V under consistent load on CPU with Cinebench.

I am (surprising even to me) using the factory BIOS my laptop originally shipped with in 2019. I’ve never updated since day 1. Version 1.07.04RIN5

I have overclocked the DDR4 thru BIOS which helps somewhat. It is factory PC2666 19-19-19-43 Micron/Hynix (mismatched sticks)!

The only other BIOS settings I can think to mention are disabling SGX, SpeedStep, VT-d.

Everything else is ThrottleStop settings and trimming the OS fat by removing unnecessary background tasks. I basically max every slider in TS and enter the largest value any field will accept. The cooling on the laptop seems to be able to handle it.

 

I thing ram parameters are very risky since I have MSI laptop bios if I make something that i can not get into the bios how will i reset it ... I have timetec brand (it was the cheapest) sk hynix memory that i have used over 2 years without an issue but overclocking or lowering timings are scary on laptop i have done it on desktop a lot but i dont want to mess it up. do you have any guide on laptops?

 

It is very unfortunate and scary how screwed up laptop firmware has become. As idiotic as one could ever imagine things being, on most laptops it has become extremely difficult to clear NVRAM completely and what would normally take a matter of seconds to correct by clearing NVRAM can soft-brick many systems making recovery difficult to impossible for some folks depending on the skillset and tools available to them. It is ludicrous to think that one needs to own an SPI programmer, save a dump of the BIOS, and have a second computer to fix simple mistakes that removing a coin cell battery used to be able to remedy, but no longer can.

Things have degraded to the point that I can no longer bring myself to purchase or recommend laptops for anyone that view their self as an enthusiast because even the most exotic and highest spec, and extraordinarily expensive and overpriced, models being sold today have critical flaws that require extensive hardware and firmware mods to mitigate severe engineering defects and flaws. People are better off having the cheapest product they can find for mobility, limiting what they do to basics (email and web browsing) on a mobile platform, and spending more for a self-built desktop. Almost every notebook made and sold today is compromised, broken, crippled trash in multiple ways. Aspiring for excellence in the mobile space has been displaced by an irrational mad dash to for having the cutest piece of junk with the most gimmicks.

 

ThrottleStop 9.2.9.2
https://drive.google.com/file/d/1_-4O51eUpYShlyXvqFuE1-CjF6pLV0mT/view?usp=sharing

New Features
- added control of Thermal Velocity Boost to the FIVR window.
- added reporting of Thermal Velocity Boost (TVB) throttling to Limit Reasons.
- added a long term TS Bench test and updated the user interface.

On the 11th Gen U and G7 series, Intel has blocked CPU voltage control. They have not just locked this feature where it can be easily unlocked. Software voltage control is no longer possible. That is why many of ThrottleStop's features in the FIVR window are greyed out. The FIVR register is still there but Intel does not allow software to read or write voltage information to this register.

 

I learned rather recently on some Clevo models you can press 'Fn + D + Power' on boot to clear CMOS.

You can also use 'Fn + G + Power' to reset GPU if it is not responding.

If all else fails I have had to pop the keyboard off (2 screws underneath) and manually remove CMOS battery to clear boot-loop issues after setting bad memory timings. Depending on the particular timing error though, if you let it boot loop several times it automatically resets BIOS factory defaults and boots itself. Just depends on which timing it is stuck on. tRFC and tREFI are the hardest to recover from for me.

 

Cleanest version yet in my opinion! Switched to Purple Prema skin! Also seems to be ACTUALLY reporting BCLK correctly and accurately! Thank you! January 1st, 2021 already shaping up nicely!

 

Done. I wish there was two of me. Then I could get more work done. My daughter was angry yesterday because I have been staying up to 1 AM or 2 AM working on ThrottleStop.

I think the new ThrottleStop FIVR TVB setting will be applicable to all Intel CPUs that use TVB. I do not own any 8th Gen hardware so I will have to wait to hear from users.

Same as above. There is only one of me. I have started working on this new feature but I got sidetracked and started working on the Alienware TVB issues instead. I had zero knowledge of TVB so I get all excited when I have a chance to learn something new. The profiles in the TPL window will be up and running someday soon.

Thanks for the bug report. I was playing around with the BCLK code. I must have forgot to remove some testing code before releasing the latest beta. I hate releasing untested versions of TS but Alienware owners needed help right NOW. Keep the bug reports coming in so I can get everything fixed back up.

ThrottleStop starts by reading this information from your CPU. If the TVB option in ThrottleStop was ticked, that means your computer originally had this feature enabled.

That is what I like to hear. Finally a way to turn off Thermal Velocity Boost throttling. Any throttling feature that can start at less than 60°C is not for me. I think my desktop starts to trigger TVB throttling at 57°C. Once again, the Intel marketing department won out over common sense.

Thanks for sharing the love. I promise to work harder in 2021. No more slacking off.

With your 10875H, make sure the FIVR - Disable and Lock Turbo Power Limits box is checked. There is some Comet Lake goodness hiding within that feature.

Edit - My Asus desktop board has an interesting feature. When fully loaded, Thermal Velocity Boost throttling will start at 56°C. Sad when "engineers" think this is a good idea.

 

Oh, now I get it. I had the Zephyrus S15 with the 10875H CPU for a few days in the month of October (it had a misaligned touchpad so returned it), and recall seeing this exact same behaviour with the all core boost. 10875H is supposed to boost up to 4.3 GHz when all cores are loaded, and strangely I saw it boosting only up to 4.1 GHz or something even though it had plenty of thermal headroom left untapped, as it was running in mid 70s, and there was no power limit throttling either. And when I scrolled down to the limit reasons, I saw thermal velocity boost saying 'yes' on HWInfo. Back then, I didn't care much about it and entirely forgot about this entire thing as the delivery guy showed up the very next hour to pick up the return, and I thought it must be a one off thing. I didn't know it was such a scam all along.

 

I wished those features worked on all Clevos and all laptops in general. What they really all should have is the same as what you would find on a respectable desktop motherboard... a good, old fashioned, never-fails, hardware button that you press that forces NVRAM to poop all over itself. There is zero excuse for laptops not having this other than the people who design and manufacture them are imbeciles that don't care about the products they build or the people that buy them, or the businesses that sell them to the unfortunate victims of their nefarious marketing crap.

 

Bclk reported as 100 is not correct unless you have modified the ME FW via FIT tool and flashed with programer bypassing write access to it.
All laptops have inserted dumb bclk spread which you cannot change and remove. It is possible to run the bclk on 100 or up to x102.98 unless you mod ME FW.
On up to 7th gen it was easy to do, while from 8th gen and up it is a bit more tricky as to change me fw icc profiles and being able to save the modded version of me fw you need to dump whole bios and insert into it new me fw, but than you need to set whole me fw from zero and that is way I still didn't do that on my 10th gen as I am still investgating things.

But back to the topic, now bclk that TS reports is buggy. If you have seen previously 99.76 or something similar, that was correct.

And yes, we are all ****ed by all vendors by 0.25% and that means you will never see advertised CPU speed/ddr4 speed/FCLK clock/pcie speed unless you do the mod that I have mentioned.

But all in all I think that it is not by vendors or Intel but by some SAR specification that they need to met to release the laptop.

 

ThrottleStop 9.2.9.3
https://drive.google.com/file/d/1nCKPjhlPXd1Ij4dkbnJBrFUQNFIQcZfj/view?usp=sharing

New Features
- fixed the BCLK bug. Thanks Krzyslaw.

No worries. I just fixed this bug. No one has to suffer with the wrong BCLK any longer. Of course, some people like seeing a perfect 100.000 MHz BCLK. Whether it is right or wrong, it does look nice.

Here is what ThrottleStop looks like on a low power 11th Gen U or G7 CPU.
Hopefully Intel is saving the good stuff for 11th Gen Rocket Lake.

 

On msi, try to change something silly in bios and save. Than hold the power for 45 sec. This should reset whole bios and clear all settings. There should be also little hole on the bottom of laptop in which you can insert paper clip. You should press it few times and than hold it for similar time as power. Efect should be the same. If it works and will clear the setting you have changed you can edit ram settings safe.

 

Yeah, no worries. I tried to explain him the problem with bclk value.

And btw FIVR - Disable and Lock Turbo Power Limits box is the thing that I check always at first when I am setting the TS.

Did you tried to check if it is possible to edit TVB temp values some way? I don't know with RW or RU/GRUB?

 

I do not know how to change the TVB temperature. I am not going to try and solve this problem. ThrottleStop already has the best solution possible. Clear the FIVR Thermal Velocity Boost box and put an end to TVB throttling.

The best throttling feature is the disabled throttling feature.
That is why I named this program Throttle Stop.

Can you check out TS 9.2.9.3. The BCLK bug should be fixed.

 

As you have seen, it's sad that some try to give me bad credit because I highlight what this really is. But I will call out trash or useless features, once I see it whatever if they try to show me in bad light or not. Nice that som see it the way the post was meant to be. +reps

 

You never did answer my question, sure you like to point out trash but you also avoided me after I proved you wrong.

 

Please re-read my posts. As well the links. Where did I say your CPU clock is going up and down? Please stop!

 

I just realized when the thread list is longer and you are throttling throttle "HOT" overlaps and they fight with each other

I will try this I know there was an EC reset button on the motherboard but will that reset all the bios settings since i have never actually used it?

 

See:
http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/page-1260#post-11067853

 

I have a question. Is it possible to set a different Offset Voltage for "idle" than "under load"?

I often find that the processor can be undervolted further under full load, but once you stop the load test and the system becomes idle, instant crash.
