The ThrottleStop Guide

hi unclewebb,

why settings on tpl window doesn't saved to each profile?

 

I've an Asus ROG GL703GS i7-8750H on W10 Pro 1809 - 17763.134 it runs TS no problem if that's of any help. Get chance I've an Acer Switch 5 on 1809, although yet to run TS as it doesn't throttle being just an i3-7130U (passive liquid cooling). Acer limits the CPU to 70C, however the i3 doesn't come close to overwhelming the cooling solution.

Ambient of 26C it will sit at 2.7GHz all day, equally no Turbo etc. TS might help to get a smidge more battery and as you say TS is a tremendously efficient monitor.

Nice to see you here!

This is the latest score from Corona, with the help of TS and it's new RwDrv.sys hack. Ran it yesterday.
https://corona-renderer.com/benchmark/results/cpu/i7-8750h

 

Yeah I saw, can pass 300K Rays on Corona & 1277CB on CineBench R15, however if want to go higher think I'll need to use a modded OS. CPU holds a solid 3.9GHz with no thermal or power throttling.

Q-6

 

Hi everyone!
I be using for many month Throttlestop 850 and today appears a text ''cpu not supported'' what can I do to solve this? I Try the last version and doesn't work appear other error.

 

@onrblbl - You need to under volt the CPU Core and CPU Cache equally. Your under volt settings are probably not doing anything. Here are 2 links to your pictures.

https://i.ibb.co/5nXH8FD/Turbo-Power-Limits.jpg
https://i.ibb.co/9qdGFZ1/Fivr.jpg

I never got around to adding that feature. Maybe someday. Maybe not.

Why not try using different IccMax settings for each profile? That should work and is very similar to setting power limits in watts.

Download ThrottleStop 8.60 from TechPowerUp. That download also contains ThrottleStop 8.50.

 

Quick question about the 'Turn On/Off' Button.

Does that allow Throttlestop to just start controlling CPU Clock Speed and Multiplier, or does it also enable FIVR voltages at the same time? I'm not sure whether it is control of undervolts...

 

please add that feature

 

@FlandersNed - Turn On - Turn Off button has nothing to do with the FIVR settings.
Turn On - Turn Off controls Set Multiplier, Chipset Clock Modulation and Clock Modulation. A lot of 8th Gen CPUs that have Speed Shift enabled do not need to use any of these 3 settings. Clock modulation throttling is rarely used on modern laptops.

I did add that feature and when those two voltages were linked like Intel XTU does, users immediately complained. Some users are convinced that being able to set the CPU Core and CPU Cache voltages independently is a good thing and it really does work. I think it depends on the CPU model. I do not have access to a wide variety of modern CPUs to prove this one way or the other so I am going to leave this feature as is.

 

Thanks for the clarification. Was getting a bit confused about whether or not the button was having effect on voltage, and by extension, temperatures.

 

@unckewebb- Thank you really much. It work better after i set them equally.

 

Hi

Could someone explain me if I can (and what) benefit will give me setting ac/dc loadline to 1 under core IA vr domain. Also by default tdc is set to 0 and disabled.
I am wondering if this will be acting like my current undervolt or what?
Currently I have also set iccmax to Max in throttlestop for all stuff. But I am thinking if setting this in bios could be benefecial insted?

I want to also ask if There is any headroom left to tweak cpu a bit higher. Now in CB15 I have 794 points and I am looking for a bit more. What I could I unlocked and tweak in Throttlestop. All power savings disabled. requested c1. epp 0, ultimate power plan, dptf fix on and so on

 

I have to check it. I never enter the GS65 bios before.

I did not install XTU. But I have MSI Dragon Center tool installed and running. I know it switch performance profile for cpu and gpu, and I dont know how. I'll check if XTU process are running in task manager.

Nice; thanks for the explanation.
I will try reboot with shift-key pressed, nd monitor the voltage. I dont use Sleep mode, but I make strong use of Hibernation (I enabled it on Windows).

I'll do some more bench with EEP 0! But for the moment I'm keeping Speedstep enabled in place of Speeshift...

 

@unclewebb can you please look if something you don't like here. I can't get all core 49x at load.

 

@onrblbl - Your image links do not seem to be working for me. If you cannot get the full multi when loaded, open up Limit Reasons and have a look to see if anything is showing up in red which indicates the reason for throttling.

www.imgur.com works great for image hosting.

 

How can I limit (but not stop) Turbo Boost? I was on a i7-4702mq and on XTU I could limit it to around 2.4 ghz. This was the sweet spot as it mean the temperature stayed under control and my performance was both good and steady.

However on my i7-8565 at 1.8 ghz I firstly have no option to change the multipliers using XTU so TS is my only option. Unfortunately at 1.8 ghz, performance is simply far too low for gaming/emulation. If I set the multiplier to 24T, it simply varies as wildly as if I had not limited it.

Any suggestions?

 

When you have a question, post some pictures of how you have ThrottleStop setup. Not only is this a suggestion, pretty soon it is going to be a requirement.

Why do you not want to run your CPU at its full Intel rated speed? Did Dell release another laptop with barely adequate cooling?

Did you open up the FIVR window? Are the Turbo Ratio Limits adjustable in that window? If these are adjustable, this is one way to control your maximum CPU multiplier.

For your CPU, I highly recommend enabling Speed Shift. Look for SST in green on the main ThrottleStop screen which confirms that Speed Shift is enabled.



If Speed Shift is not enabled, you can enable it in the TPL window. In that window there are Min and Max Speed Shift values which is another way you should be able to limit the maximum CPU speed. When using Speed Shift, do not check the Set Multiplier box.

Adjusting the Turbo Ratio Limits is the preferred method since you can set up different profiles with different Turbo Ratio Limit values for each profile.

 

Also if some guru can explain me few bios options. what is intel SA GV aka system agent geyserville (options disable/enable/fixed low/fixed high)
and what is SA GV low freq (options are mrc default/1067/1200/1400/1600/1800/1867)
In bios it is written that it is freq for low point and default for ddr3 is 1067 and for ddr4 should be 1333

 

Hello @unclewebb

I tryed, and I con confirm the offset resets rebooting or shutdown with SHIFT key pressed, and only this way.

This should be fine and comes handy... I'm just worried about invalid offset whic makes BSOD/instability. What will happen in this case? After a crash will the offset reset?

I entered the bios and no voltage control are available.

 

@unclewebb thank you for your support. I think i should stop continue cause i won't be able to go above 48x

 

Just wanted to say thank you for making this app. Using it on my HP Elite x2 1012 G1 tablet with a 6y54 chip as a streaming center for now, using Windows 10 latest build 1809.

Before using throttleshop. It... well, throttles! My use case involves the following:

• Running twitch stream with it using Windows 10 App like Unstream and 8stream, at the same time! I have a USB-C to DP adapter and connected the device to a 4k monitor currently outputting 4k60hz.
• Occasionally run Netflix and Youtube on it. Trying to get 4k30 working. Seem to be okay with a reasonable amount of drop frames (Ideally, 0 drop frame, but a dozen or so in a 10 minutes video seem reasonable

It was basically unusable at first. While Windows 10 App does not use much CPU power, it uses the GPU power a fair bit, It hit power limit and limit the GPU to 300 Mhz and make the streams skip frames.

My first instinct is to use XTU and increase the power output so it stops power throttling, but for some reason, that setting never seems to be consistent. It will work for a while but for some reason, the device just forgot the setting and go back to throttling without warning.

Switching to Throttleshop, now the power output appears to be consistent. Now performance appears to be solid. I'm able to stream 2x 1080p streams to two monitors at once without issue. 4k30 youtube seem reasonable. 4k60 max out the CPU though, probably not possible without actual overclocking and I doubt this is feasible on this device.

I'm still struggling with undervoltage to decrease temperature because it will sometime go over 90c without a fan pointing at the device. In theory, I can just open the back of the tablet and let the fan blow right into it to drop a temp to 60c but ideally, I don't want to completely remove the low profile style. Preferably still able to use it as a table when I unplug it from the adaptor without a huge hassle. However, since I can just point a fan at it, this is not a huge problem for the moment.

Undervoltage doesn't seem to do anything, both on the CPU and GPU. (I tested it by lower the power all the way down, it doesn't crash the device. Implying that the setting isn't actually taking effect. While when I lower it all the way in XTU, it does crash.) So I'm not sure what to do next. Been trying to catch up on this thread but so far no dice. I imagine a problem like this might be model/device specific?

Anyway, once again thank you for making this software @unclewebb and thank you for your dedication and support

 

I am 99% sure that if the CPU crashes, it should reset the offset voltage values to their default values.

Why not? Too much heat or do you need too much voltage for stability? If it is throttling when stress testing with the 49 multiplier, open up the ThrottleStop Limit Reasons window and find out why.

Do you know that when you use ThrottleStop to under volt, you should under volt the CPU Cache and CPU Core equally? Intel XTU does this automatically but ThrottleStop forces you to do this manually. If you only under volt the CPU Core in ThrottleStop, the CPU will ignore this setting. That might be the problem you are having.

Same thing for the Intel GPU. I believe you need to under volt the iGPU and the iGPU Unslice in ThrottleStop equally so this under volt will work. I do not own any similar hardware so the best way to test this is to clear the Unlock Adjustable Voltage boxes in ThrottleStop. Use Intel XTU to under volt and then open up the ThrottleStop FIVR window and have a look at the top right table of voltage values. You should see two voltages move in tandem with the XTU voltage adjustments. Now you can exit XTU and just setup ThrottleStop so it does the same thing that XTU was doing. Post some screenshots if you need some help.

That is the #1 complaint that I hear about XTU. Inconsistent, especially after resuming from stand by. Hopefully you can get ThrottleStop working for you so you can retire XTU. It is resource hungry and inconsistent. That's not something I want managing my CPU.

You are most welcome. I always wanted a legit reason to hang out in the forums all day. Now I have a reason.

 

This is good news. Using your suggestion I found that undervoltage for GPU is actually the iGPU unslice not the intel GPU one(It doesn't care about the Intel GPU voltage at all). And it works fine. At least this is where most of the heat came from so it is going well! Let's see how far it will go.

Pretty much, plus it is using a good amount of CPU time based on process hacker. While throttlestop really only use a tiny bit. Retiring XTU isn't really an option. That thing is good to start understanding and testing but once you established everything, XTU really can not be depend upon.

I think you got many many legit reasons to hang out here waaay before I looked into Throttlestop. Cheer![/quote][/quote]

 

Firstly thank you for replying!

Tried setting multiplier through FIVR at 30. Unfortunately the only time speed stays at 3 ghz consistently is when running the TS Benchmark. For games its better but it still wildly fluctuates beneath that and for emulation its even worse (between 1 to 1.6ghz).

How can I get it to stay at a certain speed? I did it on my previous laptop by simply capping the multiplier and when under stress the system simply operated at that consistently.

 

Do you have Speed Shift enabled? If you see SST in green on the main ThrottleStop screen, go into the TPL window and try setting the Speed Shift Min value to whatever value you like. Also set the Speed Shift EPP value on the main screen to 0 and use the Windows High Performance power profile.

This sounds like a throttling problem. The U series are low power CPUs which means they are designed to throttle. A 15 Watt power limit only goes so far. Your previous 4th Gen CPU had a much higher TDP rating. Post some ThrottleStop screenshots when it is running at this speed including what Limit Reasons is saying. On a Dell, you might not be able to get the CPU to do what you would really like it to do. I would start by enabling this feature.

 

@unclewebb I am writing this post mostly to thank you. I have an XPS 9570 with i7-8750H. I had a lot of fun and success using throttle stop.

From my initial tests, I had the feeling that the offset Core/Cache should be the same (and anyway the lowest of the two would up prevailing).
However, under certain stress tests, like prime95, I am able to sense a difference when different values are used.
Specifically, I can set Vcache=-135mv (my limit) and set any value for Vcore without having a crash.
If I monitor the VID using HWInfo64 during prime95, I am able to see a difference up until -180mv Vcore (that is the VID during the test is actually reduced as I try values from -135 to -180).
Beyond -180mv, it won't crash but it won't make a difference in the VID as reported by HWInfo64.

I have learned how to use it throttle stop here and there.
Is there a guide to clarify what each option does (especially the FIVR and TPL that are not covered in the first post)?
I managed to even set custom Power Limits and duration using your recent "Disable and Lock Turbo Power Limits".

Thank you for keeping the app very lightweight.
If you DM me your paypal address, I would be happy to offer you a beer.

 

Hello,

New to this Forum, but using ThrottleStop for a while.
A bit of history...A friend of mine has an HP laptop that all of a sudden became very slow. After a bit of testing it turned out that it became slow once the laptop was on AC Power. The moment the laptop used the battery it was fast again.

Installed ThrottleStop 8.50 and all problems were solved. Recently we got the CPU is not supported error. Time to upgrade..We tried the 8.50 version, the 8.60 and the 8.70 version but none of the versions give the same effect. The laptop stays slow on AC Power.

I made a special power management plan where the settings for both battery and AC power are the same.
Using the Intel Extreme Tuning Utility I see the Max Core Frequency/Processor Cache Frequency dropping from 3.19 Mhz to 0.40Ghz. once the AC power is on.

Wondering what settings to use in the latest version of ThrottleStop to eliminate the AC Power throttling behaviour.

 

@BrianNoteBookReview - I think I already sent you an email about this. Disable BD PROCHOT. Problem solved.

@abujafar - Someone, somewhere told me that using different Core and Cache offset values was only useful when running AVX instructions. I do not have access to a wide range of recent CPUs or proper documentation so I have no idea what the truth is. It might only be certain types of AVX instructions like AVX512.

I recommend that a good place to start would be to keep the Core and Cache offsets equal. Once that is dialed in, then you can do some more testing and find out if setting these differently is useful or not. If your testing shows that on your CPU, this improves temps or performance, I am not going to argue.

Thanks for the offer to help financially but the donation box closed up shop quite a while ago from lack of use. In the words of Bob Of All Trades, this software is brought to you by my wallet.

Head to the 20 second mark of Bob's video for further info. Users are having fun with the Overpowered WallyMart laptop that he tested. After some minor TS tweaks, there are less throttling issues compared to many mainstream laptops.

 

That would be me.
Although @hackness found something acting strange with different offsets being used first, so I got bored and found out what was happening.

I did not fully test (or can I be bothered to) the difference between core being set higher than cache, vs cache being set higher than core--someone else wants to do it be my guest, but what I found out was that the higher of the two voltages (regardless of which one is higher) is used for SSE2 (non AVX) instructions. When AVX instructions are used, either the CPU cache voltage is used, or the lower of the two voltages is used. You guys need to test that for yourself. The only one I tested was cache being set lower than core, with AVX, the lower (cache) voltage got used. I don't know what happens if cache is set higher than core voltage and AVX is used. I don't want to guess, either.

 

I currently don’t have much time testing, but I’ll do a brief summery of what I found in October last year:

1. If you set CPU offset to be 3x lower than the cache offset, you’ll find that voltage change would be less than 3mV when the AVX instruction kicks in, for example CPU offset -150mV and Cache offset -50mV.
2. If you did the above settings and run Prime95 with AVX instruction enabled, you might find the some of the threads’ usage isn’t reaching 100%.
3. If you set the cache offset to be lower than the CPU offset, you’ll find that the behavior would be the same as both set to the same offset value, and the voltage change would have a difference of 30 to 45mV when AVX instruction kicks in, for example CPU offset -25mV and Cache offset -75mV. And if you run Prime95 with AVX instruction enabled, it should reach 100% usage on all threads.
4. I don’t really need AVX instruction so I set my CPU offset to be 3x lower than the cache offset.
5. Please note that my tests were carried out under the environment that the AC loadline and DC loadline set to 5 in the BIOS.

 

Hello,

This did the trick. Not really understanding why it does this, but I will watch the video for hopefully more info. Glad to have this working so my friend can work again
Thank you so much for the support you gave to us!!

 

Usually a temperature sensor goes bad on the motherboard or in the power supply. I am not sure either. I just know that disabling BD PROCHOT is the only cheap way to get this problem fixed.

No one likes using a computer that only runs at 400 MHz. That is like trying to run Windows 10 on a 20+ year old laptop.

 

Hello everyone.
I've been using ThrottleStop for a while now and have to thank UncleWebb for all of their hard work. Today I decided to join the community and learn a thing or two from the professionals.
I wanted to get some opinions on my ThrottleStop settings from the professionals here. I uploaded screenshots of the main window, FIVR window, and TPL windows.
It is worth mentioning that I own a Dell Inspiron 7577. I have the specs in detail on my profile.
Thanksss!!!! LINK TO SCREENSHOTS

 

@Mike B. - The 7700HQ is a locked processor so it cannot be overclocked. This means you can use the default turbo ratio limits of 38, 36, 34, 34. Going higher than default settings will not get you anything on a locked processor.

I have never found a reason to check BD PROCHOT. If it is not causing any problems, I guess it is OK to leave it checked.

In the TPL window, I like using 28 seconds for the time limits. That seems to be a common default value for the mobile processors. ThrottleStop lets you set the power and time limits sky high but these kind of settings might be ignored by some CPUs. If the time or power limits are not causing any throttling problems then leave them as is.

Overall your settings look good. Are you having any throttling problems?

 

Nope!!! Not having any throttling, CPU usually hangs around 3.4 GHz to 3.8 GHz but never goes lower than 3.4 GHz. And temps almost never go over 75°C.
Also, I am confused about "Disable and Lock Turbo Power Limits" option in FIVR. Because I don't know if this will work with my CPU and whether it would it improve my performance or not.
Thanks again!!!

 

Put speedshift values to 80 instead of 0.

 

Can somebody please explain what EDP power limit is and by what can be triggered?
Also what is RING?

Is there a way to figure out when PL3 is triggered and by what?

Thanks!

 

7700hq can only be overclocked by around 100MHz with 2.98% BCLK. But for now this is the max because igpu is holding BCLK to move past 103 BCLK.
You can achive that with unlocked bios and modded ME firmware.
OCed 7700hq can do near 800 points in CB15.

 

Hey! thanks for the suggestion. I tried value "80" but it actually made me get stutters during games.

 

Hmmm... can you please tell me more about unlocked BIOS and modded ME firmware. Where can I get it? Instructions?

 

For maximum performance when plugged in, I have always liked setting the Speed Shift EPP value to 0. As long as useless background tasks are kept to a minimum, a fast CPU, regardless of load, is a good thing.

This will work with all CPUs since the 4th Gen. This switch also adds in some magic code for the 2nd and 3rd Gen unlocked K series CPUs.
Only you can test whether it will improve performance on your laptop. If you do not have any power related throttling problems then you do not need to use this.

 

I think you must use ISLC from wagnard to clear standby list and minimise stutters. Before using it, I used to get stutters and FPS drops now its solved!
I created a task for ISLC just like TS. https://www.wagnardsoft.com/forums/viewtopic.php?f=18&t=1256

 

I tested "Disable and Lock Turbo Power Limits" option on my laptop
Aaaand... no improvement in Cinebench
It almost seems like that it does nothing at all, even when I check the box in FIVR, the "Apply" button doesn't turn on?!

 

Thankss!!! I did not even know this existed hahaha
I will test it and post the results later!

 

@unclewebb
I was able to hit 5.0Ghz with my 8700k cpu but i was having blue screen. When i got blue screen it usually means voltage is high, isn't it? And if you could please explain to me differenc Power timit (95w) and short power limit(118w) I was first having TDP throttling then i set power limit 125w it was still same then i've changed short power limit to 120 then it was not throttling anymore from TDP.

 

Does lowering the Turbo Boost long and short power max limits in TPL window affect temperatures in any way?

In my case (i7-8750h) they are set by default to 70 (long) and 90 (short).

 

I don't think it does.

 

Changing the power limit of the CPU should of course change the temperature, since power leads to heat. The problem is those Turbo Boost Power Limits settings no longer appear to work. You can see that the PL1 (long limit) and PL2 (short limit) values aren't actually changed according to HWiNFO, AIDA64, etc. Meanwhile, the same settings in XTU are able to change those values. ThrottleStop has a sort-of alternative, which is "Disable and Lock Turbo Power Limits" in the FIVR menu, but what we most often need is to granular control over the PL instead of disabling it altogether. @unclewebb I hope this gets fixed!

 

Don't put the blame on ThrottleStop. Put the blame where it shoud be... On the notebook manufacturer. Stopp support them... Maybe they will change.
