The ThrottleStop Guide

I applied ThrottleStop basic functionality to prolong the life of my notebook, that is aged now to go in thermal isues, I was quite successful. The remarks to SandyBridge thermal behaviour and the benefit to automatically change Profiles by "Alarm" in Options are the main usage of my application. First against CPU overheating, I change automatically to a second profile with only DTS activated, to prevent CPU to Turbo Boost. The second function of option "Alarm" changes to a profile with DTS on and Multiplier along with Modulations set accordingly, to cool total set in case of GPU thermal problems.

 

+ rep added. Thanks sir for posting on NBC.

Edit. I would maybe add... During the test phase of ThrottleStop. Users should maybe put up a (conservative - or call it safe power profile) of the 4 you can put up as a kind of safe boot up profile. To avoid freezing in windows after boot. Once everything is set up and operate as you want(tweaked), put in your preferred power profile in TS options for startup. Hope you understood what I meant.

 

Thank you for this valuable program at all, all is perfect and running automatic in the startup. The programm really prolongs the life of my laptop. thx

 

I upgraded to the latest version of ThrottleStop and did the TDP level control + Disable Turbo checks; for value 1 it reported a multiplier of 8, at value 0 it changed to 25, and at value 2 it went to 27. After that I tried the game test like you said, and still got throttling with both 0 and 2 settings but they weren't as bad as before and value 0 was slightly better, so it looks like you honed in on the problem with the power consumption issue. Is the post that Takeishi quoted sufficient to look for those memory registers, or should I just stick with undervolting?

 

@xJohnSmithx @Dufus
Hello, about a year ago there was some discussion here about lowered processors throttle temps (internal PROCHOT). I also have a MSI (different model) and it sets the limit to 88ºC, which it hits occasionally (that's also the fan temperature target I think, so there's no margin). This is a 7700HQ with a specced Tj of 100ºC.

(If you're still here) can you outline what you did to set this higher? The BIOS is probably different but maybe it also has that hidden setting.

Thank you

 

Done. I added that link to the top of the first page in this thread, just below the download link. I might add that link to my sig too so people can easily find it. I really appreciate when other users come along and help with this project.

I enjoy doing the programming and testing but for me, writing documentation is about as exciting as cutting the lawn.

@clearnamereloaded - Glad to hear you are having fun with ThrottleStop. Post some pics to share your setup with others.

@Chidan - Memory address 0xFED15F50 is where the TDP Level Control is usually located in the Memory Mapped IO.



The 8 at the start of that register represents the lock bit. If the first digit is is set to 8 or greater, this register is locked and you will not be able to change it. If you set the ThrottleStop TDP Level Control to 0 or 2, you might find that this MMIO TDP Level Control register changes automatically to the same value. You can play with this setting in RW Everything but I am not expecting too much. Under volting should be at the top of your things to do list. That can make a significant difference. If you need any help, just ask. Almost forgot, does the new version of TS report your multiplier and BCLK more accurately? It took a while to come up with an algorithm that seems to work great on all of the 7th Gen CPUs that I have access to. Try clicking on the BCLK button a few times to see if the MHz are consistent.

 

With all this talk about U-series CPU, I am curious: is there performance difference between a 28W 7600U and a 15W 7600U in CPU-only loads? The 28W is needed of course for any GPU/CPU loads.

28W laptops would be just the MBP13 and ThinkPads right now I think.

 

I haven't seen a laptop with a 28W Core i7- CPU yet - Maybe I'm wrong

In terms of raw CPU performance, yes, there will be improvements.

for the ingtegrated GPU, it will be significantly faster with the Iris Plus 540 with 128Mb of eDRAM


You can look at the previous 6th gen benchmarks. The i7-7600U is only a 15W processor, not a 28W

 

Are we talking TDP? And are you saying "exactly" 28W, or is it "laptop CPUs don't go up to" 28W

Because my laptop has a i7-6700HQ rated at 45W

Hope I didn't misunderstood.

THe 28W U processor line is targeted at low power desktops. I've never seen a laptop use it.


We aren't talking tdp

Intel currently has M - 4.5W, U, 15W and 28W, HQ, 45W, HK something about 50W, and then its standard T 35W desktop, Nothing 65W desktop, and its K 91W desktop CPUs

We're talking about the TDPs of CPUs such as the i7-6587U that has a rated TDP of 28W

 

Yeah, I was wondering because you were mentioning i7-CPUs in general, wasn't sure if that line was still in the U CPUs only context.

Edit: also

Gotta make up you mind bro

I'm talking about TDP.

I believe the MacBook Pro 13 with touchbar all use 28W U-series CPUs, such as the 6267U . Both the i5 and i7 have PL1 tdps of 28W. Just wondering if there's any benefit to it in CPU-only computations.

 

Well, higher TDP is usually associated with higher clockspeed, so I guess there's your benefit.


Envoyé de mon iPhone en utilisant Tapatalk

 

I haven't had a u-series CPU in a while, but I recall them only needing 12W or so even at full load turbo.

 

And it's a MacBook so idk how they manage there power settings. Well all I can say, really, is that by adjusting the TDP setting on my Asus laptop, it gives 2.1Ghz base clock @35W and 2.6Ghz base @45W, so I'll let someone else take over on this subject.

I run version 8.48 on server 2012r2 and the program fails to minimize itself. I can only close it.

I checked the minimize on close and startup minimize but even at startup, the program launches the full window.

Now if I launch manually the program, it does launch the full window and remains in the bottom corner of the screen.

i launch the program at startup by putting a short cut in the startup folder of windows

 

As I was requested to send pictures of my Obsidian application: After 10 successive shutdowns I minimized my options in OSIDIAN dramatically and also in overheat protection of Core Temp. Now it works as "designed". The Obsidian application consists now of 2 Profiles, the first with no options set, the second only with a multiplier of 18 out of 8-31 connected by Option "Alarm" in case of DTS 10 or/and GPU 90. No advanced application I could demonstrate as pictures, best regards, Rudolf Zlabinger

 

TS Obsidian does report more accurately than 8.41, both at high and low end performance. And thank you very much for all this help, I'll try some undervolting and see what happens.

 

Have you tried the Clear Icon Cache solution? There is a link included in the ThrottleStop folder.

Experiencing problems using TS 8.4.
Sometimes when laptop hibernates then wakeup TS just crashed silently.

Running Win10Pro, Dell XPS 9560 i7-7700HQ.
Pls let me know how I can troubleshoot this behavior.
Mine config in attachment.

 

@unclewebb - I undervolted the CPU core and cache offset voltage by -100 mV each and tried some gaming tests, and the results are impressive ; not only am I not experiencing any more throttling, but I'm now also getting consistent clock speed at the CPU's maximum performance! Before Limit Reasons always showed PL1 lit yellow and the clock constantly varied by a few hundred Mhz even under minimal stress, but now it's smooth sailing across the board. It boggles the mind that these tests couldn't have been performed by the manufacturer, but thanks for setting my system straight.

 

@unclewebb: Do you recommend upgrading to 8.48 from 8.40 on i7 6700HQ? Will swapping out the ini file will work straight off the bat or should I start from a clean slate on 8.48?

 

I don't remember well, but is 8.48 the one introducing the obsidian theme? I simply renamed the old ThrottleStop.exe file (to keep it just in case) and past the new one in my ThrottleStop folder. I have a 6700HQ and don't have any problems.

@Vasudev - For 6th and 7th Gen CPUs, definitely upgrade to TS 8.48, Obsidian version. Follow @Takeishi advice. Copy new ThrottleStop.exe into your current ThrottleStop folder. If you ever have any icon related issues, clear the Windows icon cache.

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

@Chidan - That's great news. I told you some under volting would make a big difference. I have no idea why Intel is including so much extra voltage in their recent CPUs, especially the low power U series. It is proving to be totally unnecessary. The environmentalists should stop harassing the oil companies and they should go after Intel instead. That is a lot of wasted energy when multiplied by the number of computers world wide with Intel inside.

The original algorithm I dreamed up was a mess when I tried it on a 7th Gen U so I had to do some further tweaks. Thanks for that feedback.

When you say that TS has crashed, can you explain that further? After you resume from Hibernate, when you open up the Task Manager, is ThrottleStop.exe no longer running? I have never seen this happen with any version of TS. If ThrottleStop.exe is still listed in the Task Manager but the TS icon is missing, clear the Windows icon cache as mentioned above.

How are you originally starting ThrottleStop? If you are using the Task Scheduler, make sure that it is setup correctly and that nothing is checked that should not be checked.

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

If you are under volting, how much under volt are you using and what sort of stability testing have you done? Your under volt might be fine for gaming but it might not be stable for other tasks.

As soon as the CPU resumes, it initially uses whatever voltages that the bios gives it. After that, ThrottleStop takes over control. Post some more info so I can help you figure out what is going on. I created the Use Default Cache Ratio during Windows Stand By option for my Lenovo laptop which solved an issue I was occasionally having when resuming. Give that option a try if you haven't tried it already.

 

For the 7th Gen U CPUs, if you do some under volting, 15 Watts should be enough to run most CPU dependent apps at full speed. If you are not under volting and you are running apps that use a lot of AVX instructions, a 28 Watt U CPU would help maintain full speed. A 28 Watt U CPU would also be useful if you are trying to get maximum speed out of the Intel CPU and Intel GPU at the same time such as when gaming. Strange that so few WIndows devices are using the 28W U. This was the first that I heard of them.

Here is a U running LinX while maintaining the full 35 multiplier.



The 7th Gen are very efficient compared to a couple of generations ago but if limited to 15 Watts, the MHz would probably decrease 15% to 20% in this test. I see my daughter's 3rd Gen U laptop sitting near by. Might have to do some LinX torture testing to see how far Intel has come.

 

About that point, as I remembered and if Intel still insist in their rule, Intel can guarantee the CPU is still running without error in their deep and true function tests(according to the history, there are some tools or so-called emulator to test CPU in the CPU manufacturers at 90's, about the age of Intel Pentium[586], so we can see that the CPU development started to be grown much faster than before) at 20% overclocking to maintain the CPU quality in mass production. Thus, we can found that there is much room to overclock the CPU(as my previous notebook, SU9400 1.4GHz can be OC to 2.1GHz) or nowadays under-voltage the CPU to decrease its temperature to avoid throttling. Thus, it is normal the CPU voltage is higher than our expectation due to the 20% OC quality rules(If the role is still valid but I believe it is).

 

Thanks @unclewebb. Can i change the theme to light instead of dark. I see your max temps are 95C, perhaps is it the stock paste?
Any chance of fiddling with cTDP on TS, I really wanted a cTDP feature that only applies to the battery profile. For example 45-56W TDP on Performance profile and 35W for battery profile.

 

@unclewebb sent you a big pm, let me know what you think

 

After several shutdowns from Core Temp, limited to 100°, I applied the following settings of OBSIDIAN, now my device works again "as designed". I present 3 files, showing profile 1 and 2, 1 for normal operation the profile 2 to cooldown in case of heat issues, automatically changing between by option Alarm.

 

@cktducky - I know Intel includes extra voltage so they can guarantee long term stability for their processors. I just think that -100 mV of extra voltage when a CPU is brand new is too much. This is causing unnecessary heat, reduced battery run time and performance issues for all Intel based laptops. Maybe Intel needs to work on some new technology so the default voltage for a CPU varies during the life of the processor. The CPU could test itself on a regular basis and based on the results of this built in stability test, the CPU could decide to increase the default core voltage by an extra 10 mV per year for 10 years or use however much extra voltage is needed for stability. Adding 10 mV per year makes more sense than adding on 100 mV the day a CPU leaves the factory because it may need this extra voltage some time in the future.

ThrottleStop has been the same gray color for years. It might be 6 months or so before a gray option returns to TS. Adjustable TDP settings for each profile sounds like a more important feature for me to work on.

@Eason -

 

Thank you, @unclewebb, for the CPU voltage hint. I will look for possible adjustements in my Obsidian application. Deplorable only, that the FIVR menu is not available for me, maybe you varied according the device facilities, so I cannot adjust voltage, however, there maybe a simpler way to adjust. My device is now 5 years old, so for example Speedstep and Multipier works.

 

The app give control over a lot of features, but this only works if the CPU has that feature. It must also be unlocked.

Hallo @Takeishi, I also scanned BIOS for related unlocks, and also the other adjustements in the menus, Thank you for the hint, that would me otherwise make to do so.

 

I hope CPUs don't degrade that fast, has that been your experience? I've undervolted a laptop CPU before to edge of stability & it was stable like that for 2yrs+ until I bought a new laptop; I've had the same experience with overclocked GPUs overclocked to edge of stability & they were stable for 5yrs+ until I stopped using them due to obsolescence. I'm wondering then if my overclocked 6700K will start to degrade then? My understanding was that it was really only high voltage & high temperatures that caused degredation. I can understand that a well looked after CPU might degrade after the 10yr mark say, but before?

 

I think it's Intel's attitude is not really about fast degradation of voltage requirement. It's more about quality control and efficiency. They are not doing extensive tests on cpus and they are testing only few samples which means that if they apply a safe overvolt they get:
- less faulty or demoted cpus from the same production
- still acceptable temp
- some cpu with decent overclock/downvolt (making enthusiasts happy).

Their overvolt is just a safety factor they use to keep better profits. Making extensive tests to apply a "close-to-the-edge" voltage for each cpu would be very expensive and lead enthusiausts to an already optimized piece of silicon (no fun no party).

KabyLake usually grants allows less downvolt because their production is more efficient/refined and thus they were able to reduce their safety factor over SkyLake. For the same reason, since they are selling chips at almost the same frequencies, you can get few hundreds of MHz more with KabyLake over SkyLake with proper delidding and cooling.

 

This makes sense what you say, I'm inclined to think it's for the reasons you listed rather than to safeguard against any future degredation - that would also fit in better with my experience with undervolts & overclocks remaining stable for multiple years (ie no degredation).

 

Yes, I absolutely agree with you!

 

I just love how @unclewebb keeps making ThrottleStop better and better. Too bad we can't say the same thing about what Micro$loth does with Windows.

 

for the special Fox Tornado version of ThrottleStop. That should look good in the next TS video you do.

I enjoyed the recent Windows 10 clean up project you posted. Highly recommended.

 

Yes, it will look amazing. I'm going to have to do another one pretty soon and that will make it all the nicer.

 

@Mr. Fox & @unclewebb : Did TS become open-source or is it photo-shopped?
Mr. Fox have you tried tweaking No. of threads to 12/16/24 to get a bump in scores OR 100% stress test tool for CPU OC.

 

No and no. @Mr. Fox has been a long time supporter of ThrottleStop and I have always appreciated his helpful videos so I decided to create a special version of ThrottleStop for him. Anyone with over 17,000 rep points on NBR deserves some recognition. He has also helped guide TS development, making sure it doesn't become a big, bloated mess like some programs and operating systems have become.

 

It's always a pleasure supporting you and a product as awesome as ThrottleStop. There are a few heroes in my overclocking world, and you're one of the few, bro. You're in good company with @Prema, @Mumak, @svl7 and @Johnksss@iBUYPOWER on my list of Rock Stars.

 

Hey guys i have a question please.
i've been having my laptop stable with undervolt -110 or -115.. everything ok.. then i started lately to play with my gpu overclocked ( +170-200 mhz on the core) and i've been experiencing randomly some system crash but not graphic driver crashing.. but rather my system rebooting like when it happened when i had undervolt pushed too hard.. now the question is.. do i have to reduce my undervolt when i'm overclocking my GPU even if it has nothing to do with the cpu? like if the cpu needs more power when i overclock my gpu? or could it be possible that the system reboot while gaming is just related to my card being overclocked too much? in that case i would expect a driver video crash.. rather than a reboot? right?
thank you!

 

Maybe your CPU gets hotter when gaming due to the GPU being stressed too - thereby perhaps creating a unstable undervolt due to increased temperatures. Or maybe the increased overall power usage of the notebook somehow decreases the 'cleanliness' of the power going to the CPU - thereby creating an unstable undervolt. You could always try reducing your undervolt when gaming to see if it still crashes - if it doesn't then you've got your answer.

 

It looks good in these screen shots, too.

Too bad Windows 7 doesn't support your system ... Just kidding, actually It is so good to see all these best combinations, Win 7, 3Dmark11, Throttlestop, Pascal, Kaby Lake, DDR4.

 

Indeed. Windows 7 is alive and well, and that is a threat to the success of their latest piece of crap OS, just as it was the bane of Windows 8's existence. The Redmond Mafia are pulling out all of the stops now and are willing to stoop to digital genocide to create an impression of success with Windoze OS X Creators Abortion.

My completely valid and legit Windows 7 Pro product key, purchased for and used only on this system, was suddenly and mysteriously blacklisted this weekend. My activation was lost for no explainable reason and when I attempted to reactivate I saw a strange message something along the lines of " this operating system version is not authorized for your product" or " your product is not authorized to use this version of Windows" (cannot remember exactly what it said... wish I had saved a screen shot). It was a chilling message and one I have never seen before. I had to resort to dishonorable means to reactivate it.

If this is the kind of experience we can expect more of, I won't hesitate to use whatever means at my disposable to continue using my preferred operating system for as long as I want to. If doing it legit and paying for it (which I have always done until now) doesn't work, then I'll do it the wrong way without batting an eye. These Nazis are not going to make my decisions for me. They don't have a say in the matter and if they think they can, then they can pucker up and plant a wet one on both sides of my gluteus maximus.

 

Maybe WU detected it as Kaby Lake CPU during the detection process and flagged it with the message you posted above. If you want Windows 7 so badly become a pirate.

 

So is anyone else having an issue with 8.48/Creator's update on W10 and the TS taskbar icon not showing up? I've tried resetting TS, re"install"ing it, wiping the icon cache.. Nada.
