The ThrottleStop Guide

Search works good @ this forum:

If a 4th Gen CPU is throttling, you definitely should be running Limit Reasons to find out why. The ThrottleStop TDP throttle indicator is accurate but it leaves out the exact reason why. This reason can change from one run to the next so Limit Reasons fills in the details.



My Y510P has the Short term package limit set to 58 Watts but when running Prime95, it is more like a 56 Watt limit. PL2 is in Red. As time progresses, it will switch to PL1 and throttle down to the long term 47 Watt limit. EDP is the current limit. You might be hitting that one too. If this is unlocked try setting it to 256. That's a magic number.

 

Limit Reasons only shows Core and Ring PL2, switching between red and yellow randomly.

There are three pictures in this album, and as you can see, the TDP throttle radio button is checked for different package power values, and so is the colors on Limit Reasons. UnCore never gets limited.
Setting the Power Limit to 256 seems to allow it to have a steady ~53W TDP limit, instead of a huge varying range. Turning the brightness low gives a 54~55W range.

Anything higher than 33x multiplier is impractical for this laptop anyway, as it'll hit 90 C quickly, and will work his way up to thermal shutdown in a matter of minutes, even with a cooling pad. 33x is pushing it, but it still can hold its own without shutting down. But it's fun to push it to the limit, and find out what's causing it to limit itself =)

On a side note, @unclewebb could you please add a timer function for the Alarms? Currently I've set an "Alarm" for when the DTS's at 7, it'll turn to a Turbo disabled profile. But as soon as it does that, it goes out of the Alarm range, and turns back to the original profile, which brings the temps up again and shortly hits the DTS, repeating this pattern for a long time. (is that bad for the processor?)
Adding a timer function would be great, because I would be able to set that if the DTS Alarm profile criteria is met, it'll stay in that profile for, say, 10 seconds, before being allowed to automatically leave.

 

Core is the processor. I thought Ring and Uncore were the same, and should be CPU cache, but I can't be certain.

Performance keeps on getting better! Here's an update on what i played with around so far.
I did a lot of reading before undervolting and read my processor i7-4810mq is capable of achieving an undervolt between -50/-70. so i tried with -50 and pretty good so far.
For pp0 power limit if it's not checked, should you check it?
Open to suggestions as always of what direction and what to play with it!

 

@MigaBoo - Your results are looking better and better. Before playing around too much with voltage you should decide if the 38 multiplier is good enough. 38 is good but 39 is better. You might also want to try the 39 multi when 1 or 2 cores are active and then use the 38 when 3 or 4 cores are active. Super Pi mod used to be a popular single threaded benchmark test.

https://www.techpowerup.com/downloads/366/super-pi-mod-v1-5/

This is a reasonably consistent benchmark program that should show an improvement if you go 39, 39, 38, 38. Always fun to see some numbers for comparison purposes. Give the rest of us something to shoot for.

It looks like you are getting near the maximum safe temperature so perhaps 38 is good enough. I like setting the Min and Max Cache ratio to the same value. The next thing to consider under volting is the CPU Cache. You can usually offset it a similar amount or slightly less than your CPU Core. I haven't played around too much with the rest of the voltages. The Core and Cache tend to be the most useful ones.

PP0 Power Limit is used for throttling purposes. Your laptop is not using this so there is no reason to check it.

It is always a good idea to run the Limit Reasons program to keep an eye on your processor when bench testing. Before using it, click on the headings to clear any previous results. If something is showing Yellow that means that it recorded some throttling since you booted up. Red means throttling is in progress and it will show you what part of the processor is complaining so you can tweak your settings.

Looks like you are having fun. I think I am heading to EBay to see what some more fun will cost me.

 

Does ThrottleStop need to run in background continuously in order for undervolting settings to apply, or can I just set the undervolt and close ThrottleStop?

 

@unclewebb You hit the nail on the head. Hq aka BGA chips shouldn't be in a laptop. Best place is in a tablet/phone or a wifi router.

 

Remember that undervolting is relative! At "default" voltage at 3.8GHz on my 4800MQ, I'm at 1.0851v. With a -50mV offset from "default" voltage at 3.8GHz for you, you're at 1.1252v. This means your default voltage is higher. Try to figure out what the lowest safe voltage is for your OCs. Your chip can handle 4GHz on 4 cores as its max OC, though it appears your laptop isn't capable of cooling it.

 

A lot of the throttling options won't work yet, not sure if this is manufacturer specific or intended behavior of the new CPU. [Throttlestop 8.00 Beta 4]

 

What options do not work? No one has bought me a 6th Gen laptop yet. So far I have been taking some wild guesses to try and support these new CPUs.

Your screenshot seems to show that Clock Modulation is working correctly. I disabled Chipset Clock Modulation because I do not think the new chipset uses this type of throttling anymore.

If you open up the TRL window, see what the Non Turbo Ratio is set to. Depending on this setting, it can block the Set Multiplier feature from working correctly. Set this to zero if it is not locked, put a light load on your CPU like a single thread of the TS Bench and see what it shows as you adjust the Multiplier while the test is running.

By the looks of it, ThrottleStop seems to be mostly working for you. Considering that I have done zero hands on testing, it doesn't look too bad. Post some more screenshots of the various windows if you would like me to try and improve Skylake support. These new CPUs do not use FIVR so all those features are gone from ThrottleStop for the 6th Gen CPUs.

Edit - Does Limit Reasons still work? Dufus might need to do an update if that is possible.

 

Clock Modulation, Set Multiplier and Power Saver have no effect on clock speed even with them enabled with Non Turbo Ratio set to 0. Disable Turbo works well and it fixes the multiplier at 26x.
I am not sure if Limit Reasons works, since I recently moved from Throttlestop 6.00 with i7-2670QM and this CPU won't reach 90+ °C for thermal throttling.

 

Hello unclewebb.
Congrats on your ThrottleStop apps. You certainly struck a chord in the CPU tools dept.

My question is a basic confirmation to the risks stated in your disclaimer warring...
With my still viable DellM4400 Precision Notebook Workstation with DCP and PowerMrmizer's tentacled grip on the dedicated Nvidia FX770m 512MB GPU... and having it's way with the CPU, as well.
My basic concern is this... Keeping in mind as I type., I'm embarked on sorting out the processes in the disabling of Powermizer first. prior to any anti-throttling apps or
CPU tampering test apps getting used in the mix. on GPU-Z and Cupid Hardware Monitor
are used confirming undesired throttling when gaming.
That said... My CPU choices are all Socket P Intel Duo core 2 family compatible.
Specifically, the T9900 Dual Core, the Q9200 Quad Core,
the QX9300 Quad Core, and last.X9100 Single Core... All the top CPUs in the Core 2 family.

With all the main factors stated stated here... Do I have a reasonable chance using of not harming my machine with ThrottleStop? Like the System Board on the M4400 Precision, as warned in your ThrottleStop Guide.
And if there's a chance its a go... What would you suggest for a workaround, if needed?

I'm almost sure you'll say it's a no go without great risk but stranger things have happen.
This 08' technology had it's potential.
This machine is new to me., even though it's aged considerably. But still in the game,
per say. Able to run Win 10. Although, I haven't drank that Kool-Aid yet.
Which reminds me, I'm running Win 7 32bit.

Thanks for your time, unclewebb.
Any response to my concerns are deeply appreciated.

 

Thanks for the pics. They help me see what's working and what needs work.

Can you try running a TS Bench test with the Clock Modulation set to 100% and then run the same test with Clock Modulation set to 50%. If this is working, you should see a slow, sluggish time when it is set to 50%. My 4700MQ does not show any difference in MHz when using different Clock Modulation values but there is a big difference in benchmark times between the two settings.

The Power Saver option is related to the Set Multiplier option so if Set Multiplier is not working then it makes sense that Power Saver is not working either. Can you reboot and run CPU-Z before you run ThrottleStop? Click on the CPU-Z About tab and then click on the Save Report (.TXT) button. After that, open the report and Copy and Paste the info to www.pastebin.com and then post a link so I can have a look. There is nothing private in that file but you can also send me a message if you do not want to share that info with everyone. I just want to see if the register that Set Multiplier uses has changed. Intel has been using this same register for over a decade but once in a while they move things around in there. Time to go have a look at the latest Intel public docs. Once in a while they include some useful information in there.

Edit - You could also try using a higher Non Turbo Ratio like 25 or 26 and see if that makes any difference to the Set Multiplier function.

I would suggest not using the Clamp option in the Package Power Limits. That can cause throttling below the default multiplier.

Your bios has set the Package C State Limit to C1 which disables all of the package C States. Some older Asus laptops had some BSOD problems when the package C States were enabled so it is not surprising that Asus disabled them and locked this register. ThrottleStop is reporting 0.0 for all of the package C States so that makes sense.

Voltage ID is the same as what HWiNFO is showing so that is probably good.

http://ark.intel.com/products/88967/Intel-Core-i7-6700HQ-Processor-6M-Cache-up-to-3_50-GHz

Intel says that this CPU has a max speed of 3.5 GHz (35 multiplier) and a default multiplier of 26. Intel also says that the 6700HQ is a 45 Watt CPU and it has a configurable TDP mode of 35 Watts. ThrottleStop confirms that and shows that TDP Level 1 also has a 21 default multiplier associated with the lower TDP.

If you want to see some throttling, try running Prime95 Small FFTs version 28.7. I expect during that test the Limit Reasons program will light up like a Christmas tree. I think it still works.

@stringbuzzzzzz - The ThrottleStop warning message is to remind users that they need to take responsibility for their laptop. There is no way I can keep up with what manufacturer uses what sub-standard components. Some of the throttling schemes discovered over the years have been proven to be completely unnecessary and really make you wonder why they were used in the first place. After many years of ThrottleStop development I only know one thing. There are far more happy users than unhappy users of ThrottleStop. Not a single threatening email has come my way complaining that their laptop or their house went up in smoke because of ThrottleStop. This is a use at your own risk type of program but so far, the casualties have been few and the stories of success are endless.

 

Clock Modulation is working. Here is the link: http://pastebin.com/Y8Fib3sp
Ran Prime95 for quite a while and my CPU maxed out at 88 °C along with that constant yellow EDP stuff. The multiplier maintained at 28x.
Set Non Turbo Ratio to 26 and it changes nothing.

 

Yellow EDP doesn't mean anything. If it's flashing or solid Red then it means it's limiting you.

If you have some time, could you please abuse brutalize murder test your laptop and post the results for me in my thread? I want Skylake CPU data. The thread is here: http://forum.notebookreview.com/thr...-yet-i-want-guinea-pig-i-mean-testers.782689/

 

So @unclewebb it seems @Dufus' Limit Reasons needs to be updated for Skylake. According to the test in my other thread, he was TDP throttling (and possibly EDP throttling) running P95, at only 40W, and EDP wasn't lit and PL1 and PL2 didn't even show up in Limit Reasons.

 

Thank you, unclewebb...
I'll always appreciate an honest and straightforward answer like your response.

I'm still in the discovery process with to the overall picture. And if I determine any "non manufacture" related specifics as questions, regarding ThrottleStop..,
I'll be sure to try your insights, once again.
Clearly, as you account... The "What Fer?" vibe, does resonate with the various pushers of power saving tech, imposed on performance driven hardware.
As I do understand the purpose... It's an oxymoron, in principle.

May I put in one last approach here? Before I skim though 390ish pages...

Can you recall any accounts of the Dell M4400 Precision, having related successes, in the vast body of positive accounts with ThrottleStop?
Or perhaps., Having knowledge of a thread that encourages and compiles compatibility verification..? A yay, or nay chart.., so to speak, or however
the format may appear?

If nothing to that effect., I would truly support this idea of a thread that did just that. Linked to your ThrottleStop Guide thread, if you approve, for example.

Again, with sincere thanks...
Stringbuzzzzzzz

 

@stringbuzzzzzz - If I owned a Dell M4400 or any laptop that was not running at its full Intel rated speed, I would try running ThrottleStop. It is the one and only solution for a wide variety of issues and it continues to be 100% free with no adware lurking in the shadows.

Dell laptops from the era you are talking about had some of the world's worst throttling problems and to this day, many of those problems were never properly fixed. I would suggest reading about the issues that some Dell laptops were having back when your M4400 was released. Throttle Gate is what motivated me to come up with a solution for the insanity that was going on.

http://www.mediafire.com/view/1gnwmozzy0w/throttlegate.pdf

ThrottleStop is compatible with the vast majority of Intel CPUs made during the last 10 years. No need to read 383 pages of this forum and there is no need to create a compatibility matrix. Just run the program like everyone else here is doing.

@D2 Ultima - Besides PL1 and PL2, Skylake CPUs also have a PL3 and a PL4 power limit that can be set by manufacturers for throttling purposes. Maybe one of those new limits was causing the problem. I have not seen Dufus around lately but he might not have time to update a program for a CPU that he probably doesn't own yet. I am in the same boat. No money or any need to buy another computer at the moment.

 

Oh. So BGAtel has gone even further. Wonderful. =D.

I understand you and Dufus not having time/money. If I had a stable income I would be getting one of those P870DMs and would have been able to test, but alas I don't.

 

Does ThrottleStop need to startup with Windows everytime for the undervolting settings to stick?

 

Anytime you start throttlestop it'll apply.

 

Well... There ya have it.
Your feedback was worth the time asking.
This machine is one Intel QX9300 short, of a fully maxed.
I will report back when I iron out the fore mentioned and drop in the CPU above.
Much appreciated.
Happy O.C., unclewebb.

 

When starting ThrottleStop with Windows, is it possible to have it minimize to the notification area (Hidden icons) instead of having it just minimize to the task bar?

 

Thank you very much.
How do I know if it is running in background? I don't see it in Background processes or Windows processes.

 

@unclewebb Hi, can your programm works with the new Intel Atom Cherry Trail ? I have a tablet with this http://ark.intel.com/it/products/85474/Intel-Atom-x5-Z8500-Processor-2M-Cache-up-to-2_24-GHz
Thanks

 

The World overclocking record for a QX9300 still belongs to scook9. He used ThrottleStop to increase his multiplier and voltage sky high and got his QX9300 up to 4333 MHz. Impressive!

http://hwbot.org/submission/1014630_scook9_cpu_frequency_core_2_qx9300_4333_mhz

Open up the Task Manager and in Windows 10, ThrottleStop.exe should show up in the Processes tab as well as the Details tab. If it is not there then it is not running. You can get ThrottleStop to do exactly what you want it to do as long as you select the right combination of options. If you have any trouble with the system tray icons not being created properly, read the included ReadMe file that came with the ThrottleStop download.

@D2 Ultima - I might write my own Limit Reasons program someday and perhaps include monitoring for PL3 and PL4 throttling, if I find the appropriate documentation. Hooking up PL3 control is on the things to do list. My 4700MQ supports this but Lenovo left it disabled. Who knows, maybe Dell or another manufacturer is already using PL3 in some of the 4th Gen CPUs. We will never know until I add this feature.

@GiovyX96 - I think beta 4 already has that feature.

http://i.imgur.com/OuM4ID5.png

I need to change power consumption reporting from W to mW and I should also read the docs to confirm that the voltage is being reported correctly. Other than that, it seems to work and you can use it to reduce the core voltage.

 

@unclewebb
Uhm, so can i set at max frequency cpu and gpu clock? In "gaming" (just for test xD) cpu clock is about 1.60ghz instead of 2.24ghz (and also the gpu is underclocked).
Thanks

 

When using ThrottleStop on the Atom CPUs, try adjusting the turbo power limits higher. That is how to get maximum performance out of these processors. Sometimes that feature might be locked by the bios but often times it is unlocked. Increasing the turbo limit even a couple of watts can make a big difference. The Intel GPU is also limited by power consumption so increasing this limit can help both the CPU and GPU. I do not own one of these CPUs so post some pics so I can learn some more and maybe make some recommendations.

 

Ok, i will post some pics ^^

@unclewebb

OFF



ON




ON + CPU-Z



BONUS (?) XD




Uhm, it seems that nothing changes, or maybe i have to do something else?
Thanks for help

 

@GiovyX96 - Did you try increasing the Package Power Long limit? It is set to 4 in your picture so I would try bumping that up to 5 or 6 or 7 and see if your CPU runs a little faster when testing with the TS Bench.

Your CPU is running about as good as it is going to get. Playing around with ThrottleStop might get you a few more MHz but probably nothing significant that you will notice. Some Atom CPUs throttle like crazy and during previous testing, ThrottleStop was able to make a huge difference in performance. If a CPU is not throttling and if it does not support overclocking then there is not much that ThrottleStop is going to be able to do to improve performance.

Can you run the Dump tool by Dufus.

https://drive.google.com/open?id=0B0dpSo9k93jDX1Fpa1FpTmo1Qk0

It will show me some more info about your CPU. Can you Copy and Paste the information in the Dump file to www.pastebin.com and post a link here.

Edit - I forgot to mention. Even if you can increase the power limit by another watt, your CPU is near the thermal throttling limit. The cooling is adequate for your chip as is but there is not any significant room in cooling capacity to increase power consumption or performance.

 

Yeah, in this 2 hours i have test the Package Limit with some games XD
Yep, i have set it first on 5 with a little increase of fps. In all case, the max that it make is about 6.6w (with 7 as limit).
But the Ghz of the cpu is not everytime at 2,24, i think it depend on something else.
The Temp is pretty the same, the max in the Core 0 is 86°C vs the 84 stock
I tried also the turbo time limit but it don't change anything.

Ok for the Dump, take me some minutes (?) xD

@unclewebb for you
http://pastebin.com/hhvFLJXW

 

So I found out that ThrottleStop does start at logon, but it is in background processes. But after a while it would just disappear.

Edit: Apparently, it would closes itself when I change from AC to Battery. Going back to AC does not start it again.

 

The maximum multiplier for your CPU is 28. (28 X 80 MHz = 2240 MHz)

Unfortunately, the 28 multiplier can only be used when a single core is active. When you are doing some stress testing with TS Bench and all the cores are active, the maximum multiplier will automatically decrease. This feature is built into the hardware. There is no way that ThrottleStop or any other program can get around this limitation. All of the locked Core i processors work similar to this. The maximum multiplier is usually only available when a single core is active.

Increasing the power limit is likely increasing the speed of the Intel GPU. When you are near the turbo boost power limit, the GPU might be programmed to slow down first before the CPU slows down. Try using GPU-Z to monitor the GPU MHz. If your Atom is supported, it might show an increase in the Intel GPU MHz after you increase the turbo power limits.

ThrottleStop has an option called DC Exit Time. Did you check off this option? If you did, this forces ThrottleStop to automatically exit as soon as your laptop switches to battery power. You can also set the number of seconds before this happens if you want a delayed exit. If you are using this option, ThrottleStop will not start up again by itself because it has already stopped running. If you are still having problems, post a screenshot of how you have the Options window setup. Are you using the Task Scheduler to startup ThrottleStop with Windows? Did you more or less follow the method to do this that is outlined in the second post of this thread? I will try to update the screenshots in that post some day.

 

This is how it's setup. I've setup ThrottleStop to startup using Task Scheduler exactly as posted in the first page. Is it possible to not have ThrottleStop exit itself when on battery since I have setup a battery profile. Can I just set DC Exit Time to a really high number?

 

It isn't supposed to turn off when on battery, the setting is off.
Either throttlestop has some kind of bug, or something else is killing it

------

Just purchased a ThinkPad 8 for 800BRL (~200USD). That was a steal!
Let's see how the Atom Z3770 will work with ThrottleStop =)

 

I agree with the "or something else is killing it."
As it does have a confirmation to "not turning off" has an account.
Reinstall a fresh download of the appropriate version of TStop, after all bios and OS settings are returned their prior settings, before the attempts to
fix the problem.
Once new copy of re-installation is complete.
Making sure a good "once over" is done for any/all preferences in system bios being your preferred admin commands. Bios versions and providers are
known to have these areas in focus., Accommodating a priority "performance only, or "never turn off" to that effect" preference. Just as the OS's, "power
management" settings are second in line, to power priority settings. Like I said... If it applies to your bios.

Assuming there's no dedicated app that's interfering.... Reminiscent to throttling technologies of the past, still present under different logos.
If so, address the concern for third party apps.

On a physical level...
It does make prefect sense if laptops behave in this way., Simply due to a "battery's discharge conservation" default function, ensuring battery preservation.
A consideration that batteries in general, may not possess the same headroom, otherwise sustained by an AC/DC power supply's constant source of
"regulated" voltage, and over the "rated requirement" of amperage... Headroom.

 

haha what did you get off eBay?
Got it to 3.9! 4.0 is not worth with all the heat problems since it is a laptop.. still working on cooling. i have a cooling pad with 10 fans + max fans on + some eBay cooler suction fan that sucks air outta my gpu fan area.
Idles at 39/40.
no bsod or crashes.
Played bf4 for a while and handled it good. only thing is required is fine tuning since my bf4 fps sorta jumps time to time from like 70ish to 100 to 150 lool. but it doesn't down clock nor over heat.
Limit reasons gives no warnings so it should be good besides the fine tuning.
Only thing i need help is with the turbo timer and watts. I played with it for hours and this is the best i got it to!

 

It is always a pleasure seeing someone get some good looking numbers out of their CPU with the help of ThrottleStop.

As long as your CPU is not throttling, there is no reason to get too technical with the various power limits. For the Primary Plane Power Limits, PP0 Power Limit is not checked so you can ignore that setting and the PP0 Turbo Time Limit can also be ignored for the same reason. You have set the PP0 Current Limit very generously so that is not likely going to be a limiting factor during any normal use.

In the Package Power Limits, the Turbo Time Limit determines when your CPU switches from the Short term power limit to the Long term power limit. If you are setting both of these power limits to the same value then it doesn't matter what you set the time limit to. If Limit Reasons is not lighting up PL2 or PL1 then your CPU is not being limited by the values you chose for the Package Power Limits. That's exactly what you want to see. A CPU that is allowed to run at its full Intel rated speed. No throttling. Life is good,

It never hurts to look!

@Daedalus1116 - I am not sure why you are having problems. ThrottleStop stays running on my laptop without any issues whether I am plugged in or switch to battery power. Try reading the included ReadMe file and clear your Windows icon cache. If you are still having issues after that, can you copy and paste the contents of your ThrottleStop.INI config file to www.pastebin.com and then post a link here. I would like to try and duplicate your settings to see if I can recreate the issue you are having. This is the first time I have heard about this problem so it might be something on your laptop. Send me an INI and I will do some testing just to make sure.

 

Perhaps it's something on your task scheduler? It might be turning the program off when on battery, idk.

 

This is the ThrottleStop.ini
http://pastebin.com/i058syM9

and these are how task scheduler is setup

Spoiler: Pictures

 

I updated to the latest beta and my expected battery life shot up over an hour. Whoo.

 

You have an option in the Task Scheduler checked that says,

"Stop if the computer switches to battery power"

I would also clear,

"Stop if the computer ceases to be idle"

and clear

"If the running task does not end when requested, force it to stop"

In the second post I included a link to download some pics of how I have the Task Scheduler setup.

http://www.mediafire.com/download/6tnz3ccauuq3ekk/TS6_Win8_Manual.zip

I agree that the second post is overdue for an update. Try changing those options in the Task Scheduler and see if that fixes your problem.

Did you change the C7 Interrupt Response Limit setting? For me, this seems to change the reported power consumption. Not sure yet if it makes any significant difference in actual power consumption but the numbers look good.

 

Thank you very much unclewebb, I'll give it a try and report back.

Edit: It worked! Thank you everyone. Weird that those settings apply even though they are greyed-out.

 

I, uh, don't think I have that option. My laptops are first gen i5 560m and i7 920XM.

 

I am also surprised that an option that is grayed out in the Task Scheduler would cause so much grief. Glad to hear that you got this sorted out and thanks for sticking it out to the end and letting everyone know that your problem has been solved.

You are right. The new C7 IRL Option is not available on the 1st Gen Core i CPUs. I am not sure why the latest beta is more efficient. I think it is just a coincidence but I will try not to change anything to screw up your new found battery life.

 

Maybe I just didn't set something up correctly last time? I do remember the C state thingy reverting back to C0 from C6 randomly.
