@unclewebb nice work bro! Nice name too. Brother @Papusan is blushing

 

Quick question, is it possible to keep the automatic profile changing from AC to Battery and vice versa with the app closed?

Or a way to keep throttlestop running in the background with only a notification icon, and have it out of the taskbar?

 

You you can easily add ThrottleStop to the Task Scheduler and use a key command for what you want on the fly. See the link for a setup guide or you will find it in the latest part of the thread http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/#post-6865107

http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/page-288#post-9987036

 

On the main ThrottleStop screen, make sure the Task Bar option is not checked. ThrottleStop is very efficient when minimized to the Notification Area / System Tray. If you have any problems, read the included ReadMe file and clean the Windows icon cache if you need to. This is explained near the bottom of that file.

 

Hi @unclewebb:

Thank you so much for such great app, it's really awesome!!!

I've tried the Speed Shift feature and according to the HWinfo it's enabled @autonomous mode, so far with very brief testing the battery life has no negative nor positive impact.

I also realized that once it is turned on the windows power option for setting Max State will be ignored I assume it is as intended.

Just out of curious how did you manage to enable the SS while the BIOS has no such function

FYI, am on Dell XPS 15 9550, CPU undervolted to -160mv, Cache -160mv, iGPU -125mv, running rock solid stable and cool!!!

Once again Thank you so much!!!

 

8.20 findings on my system (In signature)

- I am able to downclock to 13x now whereas 16x was the minimum it would go. However it does not stick at 1300Mhz, it jumps between 1300Mhz and 1500Mhz
- To disable speedshift a complete restart is necessary (May be by design?)
- Speedshift can be used to set a max of 8x multiplier, though manual setting will not go to 800Mhz (Setting 1/1 for speedshift makes it go to 800Mhz) - Is this a bug with 6700K/desktop skylake or can TS be tweaked to go lower on these desktop chips? (I like to downclock a lot on battery when doing simple word processing)
- When using speedshift my CPU will only clock up to 39x, not 40x no matter the stress it's under

If I can help at all with testing I will definitely help out.

 

@solo16 - Microsoft decided to market Speed Shift as some sort of Windows 10, latest and greatest version, only feature but that is not true. It is an Intel Skylake feature and Intel's public documentation shows how to enable Speed Shift no matter what operating system you are running. No bios support is needed either. All software has to do is write 1 to MSR 0x770. Now the Linux guys can check out Speed Shift too.
Once enabled, it stays enabled and yes, the Windows power profiles will be ignored when Speed Shift is enabled. I have not tried this in Windows 10 v10586 yet so not sure what happens in that situation when Microsoft is also using Speed Shift. On my desktop Skylake, going into Stand By mode and then resuming disables Speed Shift. That's why I included the ThrottleStop option - Enable Speed Shift when ThrottleStop starts. If this is checked, Speed Shift will be enabled when TS starts or when you resume from stand by mode. Depending on the motherboard and what Microsoft is doing, you might be forced to reboot to disable Speed Shift.

@Plur - The lowest multiplier that the 6700K supports is 8 so 800 MHz is as low as it can go. A setting of 1 asks the processor to go as low as possible and that varies depending on the CPU. If your C States are enabled, it is not unusual for the reported multiplier to jump around when the CPU is lightly loaded. If you set a Min of 8 and a Max of 40, your CPU needs to be very idle before it is going to sit there at 8. The whole point of Speed Shift is for the CPU to almost instantly get back up to full speed when needed. The problem with the Windows Balanced power profile is that it sits at the 8 multiplier too long before getting up to speed. Some people like that but a slow CPU is inefficient so forcing it to 8 doesn't always save as much power as you think it should.

The Speed Shift register has another variable that should be able to offer some more control. It can be adjusted from 1 to 255 which varies the aggressiveness of Speed Shift. The Intel recommended default is 128. I will find some room and add this extra variable to ThrottleStop so you can play around with it. I left this out for initial testing because I could see users setting this too low, their CPU would get stuck at 8 and then they would blame ThrottleStop for making their laptop so sluggish. Writing software that makes everyone happy is a tough gig at times.

Setting this variable above 128 should allow your CPU to reach the maximum multiplier when stress testing. Thanks for the feedback. Send me a mesage in a week or two if you would like to test out this new feature.

 

I did see from the speedshift allowing it to go to 800Mhz, 8x would be the lowest. However when not using speedshift, whilst just using profiles it does not allow me to go to 8x. I can set it that low, sure; but it wont go below 1300Mhz - see here http://puu.sh/rdHyQ/681adae4c3.png

Setting it to 8x I see a minimum of 1400Mhz with clock jumps

Setting it to 13x I see a minimum of 1300Mhz with clock jumps

On the note of testing speedshift, I definitely will help you test.

 

In your screenshot is Speed Shift enabled or disabled? If Speed Shift is disabled, are you using the Windows Balanced or Windows High Performance power profile and what is the Minimum and Maximum processor states set to? What C States are being used? I have a desktop Skylake CPU that has no problem dropping down to the 8 multiplier while Speed Shift is enabled or while using the Balanced power profile. Your screenshot shows that you have a lot of background activity going on. An idle processor should not have one thread spending 11.2% of the time in the C0 state. I will post some pics in a little bit to show you some examples.

 

Thanks, I should have realised what that option did earlier, now throttlestop is bae.

 

Here is an interesting comparison. Here is how my Core i3 looks when idle while using the Windows High Performance profile.



Next up, I switched to the Balanced Profile.



For the last test, I enabled Speed Shift.



In all 3 examples, the Package power consumption is identical at 11.2 Watts. Core temperatures and the package temperature are also nearly identical. If anything, the screenshot with the CPU running at full speed shows a slightly lower core temperature which translates to the lowest actual power consumption. Not exactly a scientific comparison by any means but still, there is not a lot of difference as long as there is not a lot of crap running in the background on your computer. Fair comparisons are difficult these days when Microsoft secretly downloads gigabytes of data in the background as it gets ready for another update. While testing, Google Chrome decided it was a good time to do an update.

With Speed Shift enabled, it took a while to get a screenshot with the 8.00 multiplier across the board. Most of the time the multi was hunting around between 8 and 9. In the Balanced profile with Speed Shift disabled, it spent a lot more time stuck at 8.00. It took more load to get it to start moving up to full speed.

When testing, if Speed Shift is disabled, use the Windows High performance profile with the Minimum and Maximum processor state set to 100%.

If Speed Shift is enabled, the ThrottleStop Set Multiplier feature and the various Windows power profiles will be ignored. In this state, the CPU gets to decide what is best for performance vs power consumption.

Edit - A difference of half a volt and 2900 MHz made next to no difference. Who would have thunk it?

 

Speedshift is disabled in the screenshots. High performance profile is being used.
Here's a pic of the C-States while downclocked: http://puu.sh/rdQRX/d97a35009c.png

And here while on full clocks: http://puu.sh/rdQXa/0f7767397f.png

I don't have too much going on in the background. Steam is open, firefox is open with ~15 tabs, media player open

I have set 100% on both minimum and maximum while on AC now. Still unable to go under 1300Mhz
I don't know anything about C-states or how to rectify the issue you have pointed out (I am a noob when it comes to this)

EDIT: You said there's another setting for speedshift for aggresssiveness. What is the default setting right now without the ability to change it?

 

Hi,
I have a problem with IGP throttling
Here's the screenshot

Spoiler

Any idea why it's complaining about ring EDP and how I can workaround it?
What puzzles me most is that I got both package temp and wattage safely below limit.
CPU cores are limited to x15, cores and gpu undervolted.
Short Turbo sees IGP clocked as high as 500+ MHz, but sustained is stuck at 300 with red ring EDP.
Once I got it jittering between 300 and 450 but can't repeat that any more.
I tried to increase current limit via the Intel Extreme Tuning app but it changed nothing.
Gpuz shows IGP clock always 0, so I have to use AIDA64 for monitoring
This is lenovo 700-11 with a skylake m5 (hd 515)

 

Hello all!

Great work to @unclewebb and @Dufus for Throttle stop and limit reasons.
I have been testing different settings and have found a few stable profiles. Have enjoyed TS for two separate laptops!

My y50-70 with the I7-4720HQ and 4600/960m seems to always have the 4600 hit temp limits, this can happen before i start a benchmark. I have see the GPU warning when simply hovering over a task-bar browser icon to "peak". And 2d tests on the 4600 can cause TDP throttle - seems very strange
--- is there a setting I can change from throttle stop to limit this throttling?
---I have an unlocked bios - I have set back to defaults and I still get this behavior, are there settings to increase throttle limits?
---even while typing this post I saw red flashes on limit reasons that there was throttling with GPU power


also here are logs from Throttlestop:
https://www.dropbox.com/s/9uzfodznu5gbuja/2016-09-18.txt?dl=0
and the logs from GPU-z (watching 4800):
https://www.dropbox.com/s/kigetvdyfcdr5i1/GPU-Z Sensor Log.txt?dl=0

Picture of Throttlestop settings and limit reasons:
https://www.dropbox.com/s/gevelvo4fojsgfd/GPUpower.png?dl=0

If anyone knows where the original Dufus thread is or tutorial is on limit reasons - id love to find/read it, been searching for a few weeks

Edit:
Worked from -20mv to -75mv on the IntelGPU FIVR settings - still throws GPU power yellow/red warnings. I dont see the package power go over 47 - gpu'z shows igpu going up to 6 or 7 watts

edit2: uninstalled drivers, ran some tests without intel video drivers installed and everything was perfect... grr lenovo drivers getting uninstalled and testing will continue

 

THX for finally making this thread a sticky after almost 500 pages!

 

@Plur - Here are a couple of more screenshots to show what TS does on my desktop Skylake CPU. In both pictures, the CPU is fully loaded with the TS Bench running. In the first example, I am using the Windows High Performance power profile combined with the Set Multiplier feature. This allows me to run the CPU at any speed I choose regardless of load. It is locked at the 8 multiplier.



In the second example, I am using the new Speed Shift feature to accomplish the same thing. By setting the Min and Max options both to 8, the CPU is also able to run steady at the 8 multiplier. The results are pretty much the same either way. Same VID voltage, core temps and package power. The core temp is a couple of degrees higher in the Speed Shift example but that is only because I allowed the test to run a little longer before getting a screenshot.



With Speed Shift off, the Set Multiplier option gives me full control so I can run at any multiplier from 8 to 37 and it will be steady at that multiplier. I have the Non Turbo Ratio set to 0. I mentioned a while ago that there could be two different locations for the Non Turbo Ratio. ThrottleStop only has access to one of these settings so maybe the trouble you are having with your multi not being steady is because there is a second Non Turbo Ratio in the Memory Mapped I/O that is set to a different value. Not sure. It might be some other secret Win 10 setting. I am using Windows 7 for my tests.

The other setting I plan to add to ThrottleStop is adjustment of the:

0FFH is equivalent to 255 decimal so you will be able to adjust this from 0 to 255. Default value is 128. Not all Skylake CPUs support this feature.

@duzenko - Intel is not very clear what Other means for CPU Ring throttling.

I can only suggest a few things that may help but probably will not do anything. First of all, clear the Package Power Limits - Clamp option and try setting Package Power Long and Short both to 9. Have you tried changing the Power Balance to different values? I have done zero hands on testing with a Y series CPU so I am not going to be much help.

@barkarse - Even with an unlocked bios, I think your CPU is still going to be limited to 47 Watts. The unlocked bios might let you adjust this using ThrottleStop but I believe there are multiple settings that control TDP that ThrottleStop does not have access to.

I think that is what ThrottleStop reports as GPU POWER throttling. There is the package power limit that includes all the various sub sections of the processor package but there is also the individual CPU core power limit which is called PP0 (Primary Plane 0) and there is a separate GPU power limit which is called the PP1 limit. ThrottleStop lets you access PP0 but I never got around to adding PP1 adjustment. Not yet at least. It is possible that Lenovo set the PP1 power limit way too low so throttling happens very quickly. This register might also be locked by the bios. In the next few days I will try to play around with the PP1 register in my 4700MQ to see if I can duplicate your issues. By default, this register is not used in my Lenovo Y510P so it is set to zero.

Not sure if there ever was a separate Limit Reasons discussion. There should have been. The 3 registers that store this information in the processor are fully documented by Intel.

http://www.intel.com/content/www/us/en/processors/architectures-software-developer-manuals.html

Volume 3 - Chapter 35 Model Specific Registers. MSR 690H, 6B0H and 6B1H are the ones that TS reports data from for Haswell.

I have only been waiting for 6 years. Wasn't sure what feature I was going to have to dream up next to finally get noticed!

 

Hi I am very happy to use the new 8.2 throttlestop with the new "limit reasons" feature.
I am using it on p775dm3 (6700k, gtx1080), and I am getting "EDP other" when OCing CPU even 0.1 clock from stock.
There is no prema bios for it, but I've maxed all the power limit in TPL tab.
Any idea what EDP other is, and how I can get rid of it?

 

Hello, first of all thank you for the program, it seems to include all the functionalities I could ever wish for.
I´m working on a gigabyte p34 with windows 10 and throttlestop 8.2 and I would like to set up profiles in order to keep my CPU temperature below 85 degrees (approximately, so that it doesn´t heat up my GPU). Anyway, so I set up the profiles as adviced (secondary profile with disabled turbo) using the alarm and a DTS of 15. All is working correctly, except that the temperature (perhaps only the estimate) jumps when switching from a profile to another.
So typically when it is in profile 1 (3.5ghz) it will estimate 90 degrees thus switching to profile 2 (2.6ghz). At which point it will immediately estimate 80 degrees (which seems odd), thus switching back to profile 1, ect. So it will ask the processor to change its frequency every second or so. So first of all I was wondering if this is normal, if it is dangerous for my processor to be changing its frequency on such a short time laps and if there could be a way to smooth the estimated temperature? When I read the temperature on another program it is more stable, so I´m guessing that that other program (gigabytes smart dashboard) smoothed the values.

 

@unclewebb
I have played with it a little today
Here's my conclusion - the red edp other must mean that most energy is used by L3 cache and memory controller
If I set cache ratio to 15 or lower it stays yellow
Right now my problem is that I can't make the chip consume more than 3W
It just throttles no matter what value I set to power limit even though the package temp floats in comfortable 60s
That applies to sustained load. Short bursts are often 5W.

 

Since I uninstalled the Clevo Control center on my P650rp6 (i7-6700hq), Throttlestop isn't able to use turbo boost. I tried setting the multiplier manually, deleting the software and redownloading it, nothing. It always maxes at 26 instead of 30+ The only thing that gives me back my Turbo Boost is reinstalling the control center which sucks because It seems to conflict with Tstop.

Also when undervolting (once again everything is checked etc) my VID doesn't change at all. In idle and load, on battery or performance profile...

here's my setup






my stetup during load :

 

@Arondight You seem to have forgotten to check the set multiplier option. It's a must if you want to use the higher multipliers.

 

As you can see it changes Nothing :

 

Have you maxed your TPL settings? Also too low voltage can prevent maxed multi.
And finally..., Have you tried put bios to default settings? Have tried win power plan on Max performance?

 

So much this

@unclewebb, first thanks for your tool it's an outstanding tool and precision tool for finetuning the cpu, and what i want to say is yeah i think windows 10 still does some dirty tricks to manage the cpu, for example when i'm gaming and i leave the "balanced" power profile active my cpu NEVER EVER clocks over 4Ghz even with your tool active, if i quit the game tho and do some stress testing, x264 or your integrated benchie it boosts to my set 4.3Ghz, but if i switch to "high performance" power plan, my CPU clock stays at 4.3Ghz even when gaming, stress testing of course stays 4.3Ghz. Set the CPU to 5% min thingie in the power plan settings the CPU downclocks fine too.

What i noticed too with SpeedShift enabled my CPU stays max at 3.8Ghz gaming and stresstesting but downclocks fine, have to set min/max for your new SpeedShift option to 43 so that my CPU clocks work, curious if your future setting you mentioned about the SpeedShift Sensitivity fixes this. Oh and sometimes your "Power Saving" Feature get's stuck for me somehow, for example if i'm using high performance power plan CPU @ min/max 100% ofc it stays 4.3Ghz, then when ticking your option the CPU downclocks fine to x8-x13 but doesn't go to full power anymore, namely 4.3Ghz, just stays at x13 Multi even when stress testing and gaming .

 

You guys were right, the issue was the power plan. It's weird because I made a custom power plan where I put the cpu power to 100% when plugged but for some reason it still disables turbo. When using the high perf plan which has the same CPU settings, turbo boost works... I don't get it, but it works so I'm happy.

Sadly still no change in VID , any idea ?

(This software is awesome really)

 

I think nonturbo ratio on the FIVR page should be set to 0 or 1. I saw that earlier in the thread, but not sure where.

Joe

 

@ unclewebb
how many bins i3-6100 dose have?

 

Пофиг.

 

None. i3s don't turbo.

 

Hey bro, how the hell were u able to overclock 17 4710hq to 4.7 ghz??

 

If you Google you will find more about the topic http://forum.notebookreview.com/thr...-intel-haswell-cpu-microcode-bug-hack.790177/

 

Okay thanks man, but i dont think that much clock speed will be stable for long right? i mean it will get very hot. hey man, please tell me which settings work the best for i7 4720hq, i have to use throttlestop and optimize it to the fullest. can u also tell me something about vccin? what value would be good?

 

So this is my first day using this software to undervolt and I think I'm running into the same issue as you. I'm trying to set certain offsets for power saver and others for gaming. When I unplug, it automatically shifts to gaming but my offsets stay the same as in power saver. I'm switching my Windows power profile like I should but it's not consistent. Only once did it change the offsets but never again. I'm not sure what I'm doing wrong.

 

I am here to help but first I need you to help me. Post some screenshots. Lots and lots of screenshots. Show me how you have ThrottleStop setup and show me what it is doing that you do not think it should be doing or tell me what you are trying to accomplish with it. Include as much background info as possible. Start with a single profile and learn how the program works.

Are you using Intel XTU, are you using the default Windows High Performance power profile? Do you have a Skylake CPU and are you using Speed Shift, Windows 10, etc. etc. Do you know that some 6th Gen CPUs need the CPU Core and CPU Cache voltage to be set equally before the voltage offsets will be applied?

@Arondight - Some ThrottleStop settings only work properly when using the default Windows High Performance profile. Some people do not realize that Windows power profiles contain many hidden settings so a custom profile that seems to be similar to the default Windows High Performance profile might have some significant differences that are not readily apparent.

If your Windows High Performance profile ever gets corrupted, open up the Power Options and click on the Restore plan defaults button.



The ThrottleStop Power Saver feature is from the Core 2 Duo era so I avoid using it. Power Saver still works on Skylake CPUs in Windows 10 but there are better ways to control a Skylake. All Power Saver does is it adjusts the same register that the Set Multiplier feature adjusts. For Set Multiplier to work correctly, the Non Turbo Ratio has to be set to zero (0).

With a 6th Gen Skylake, if I need a low multi when the CPU is lightly loaded, I would enable the new Speed Shift feature. I have finished adding an adjustment to ThrottleStop so a user can fine tune Intel Speed Shift. This adjustment is called Energy Performance Preference (EPP) which lets the CPU know if you are interested in maximum performance or power saving or anywhere in between. This next version should be released in a day or two after I do some more testing.

No time for the forums while I am working on improving TS.

 

@unclewebb: Thanx for this great tool, I have been using it many years mainly for undervolting C2D laptop with great success. Now I bought a new laptop, undervolting went great, but having some problems - any idea how to get any lower package C state on i5-5200u? It seems to be using only c2 package state (Thinkpad Yoga 14)...In comparison acer v5-573g using i5-4200u is using mostly C3 package state and has lower package power despite using older CPU and a larger screen...

 

@unclewbb Just for clarification, does that mean that if we choose "Windows High Performance profile" we should not adjust items like "Require a password on wakeup" but rather leave everything in the "Advanced settings" window at default?

 

Just choose Windows High Performance Profile, you can probably make changes to the High Performance profile though if they're not CPU related settings, but make sure you always have Max & Min Processor state set to 100% and the Windows High Performance Profile selected.

 

Heads up. The 8.20 zip file gets flagged for containing this [ https://www.microsoft.com/security/portal/threat/encyclopedia/entry.aspx?name=Trojan:Win32/Spursint.A!cl&threatid=2147705703&enterprise=0]

False positives happen, but I'm inclined to think either I've been MITM'd or that we should cease using SendSpace or whatever. @unclewebb, at your convenience, could we get this uploaded elsewhere? My personal recommendation would be Mega, of course.

 

Hello All,

Sudenly throttlesptop stops working. messages : this beta version has now expired (version 810b2 which is the llatest one).

Any idea ?

 

Update to the new one (8.20).

My bitdefender and MBAM doesn't detect it, what antivirus are you using?

 

Thanks for the tips and quick response Robbo9999!

For downloads I run virustotal.com (google subsidiary). They check a file for viruses on ~50 anti-virus software packages. ThrottleStop was getting dinged by an antivirus software a while back but you can do a search here regarding false positives

I think that is because a new version of ThrottleStop is being issued in the coming days per the developer unclewebb. I get same message with v. 8.20.

 

I'm running Windows 10 Build 14393.187 with Windows Defender Definitions Build 1.229.210.0

No such issue here. I believe you may already have some rootkit or malware on your computer; it is extremely unlikely that you are being MITM'd.

 

@au9879 - My Asus - Skylake desktop has the same issue. The bios allows adjusting Package C States up to Package C8 but none of these settings actually work. They all default to the same package C2 and that's it. On a desktop board, this is mildly annoying. On a laptop, this increases power consumption and heat and also decreases battery run time. My daughter has an Asus laptop with a low power 3rd Gen U CPU and it can spend ~90% of the time in Package C7 when idle. Not sure what some manufacturers are thinking.

You can try contacting Lenovo but you probably won't get anywhere. Most manufacturers will tell you that third party tools and any info they report are not supported. Have you tried adjusting the Interrupt Response Limits? My Lenovo Y510P - 4700MQ has these default settings,

C3 IRL - 66
C6 IRL - 106
C7 IRL - 145

with Time Unit set to 2, 1024 ns. I plan to keep looking into this to see if there is a register or a Windows power profile setting that can be adjusted to enable the deeper package C States.

I said this once but it needs to be said again. I do not want access to your PC. I spend too much time on my own PCs. I just ran the TS8.20 zip file at www.VirusTotal.com and 55 out of 55 virus scanners are happy with ThrottleStop. I continue to use SendSpace because it is one of the few sites that my friends in China can get to. Many reputable download sites including Google Drive are blocked by big brother over there.

@pressing - The problem is that some manufacturers create their own Windows power profiles that might be similar to the Windows High Performance profile but there can be significant differences. Options like requiring a password on wakeup are not going to cause any problems for ThrottleStop. If you are having any problems, switch to the default Windows High Performance profile and go from there. On 6th Gen Skylake CPUs, enabling Speed Shift takes control of the CPU away from Microsoft and that's a good thing.

 

What is the meaning of this red label(gpu power) ？

 

Hey man, i have to discuss a few things. Your mentioned that windows high performance mode in needed for some functions, can you please tell which functions are these? Also, for some reason, whenever i set a higher turbo short time power limit than stock, i check it from intel xtu and it is not set. I don't know why this is happening as it is not the case with turbo long time power limit. Also, sometimes while playing games, if change a few settings (stable settings) after sometime playing the game, the laptop switches off suddenly and restarts.

I don't know what exactly is going on here but my CPU has never throttled down below 800 MHz before at idle.


Strangely my cache ratio was 4 in the FIVR window but as soon as I tried to change it, it jumped back to 8.

Also, using the speed step controls seemingly does nothing.

Not a deal breaker - it seems that I now have to set minimum package power % in the power control panel to 30% to restore the previous behaviour. The CPU actually consumes more power at this lowest CPU state than at 800 MHz (I assume because of C7 and higher states).

 

Just replying to the bit about your laptop shutting down on its own. Sounds like whatever changes you're making to your CPU are not stable - like an undervolt that's not stable. Or maybe your laptop is sucking more power than the power brick can handle, and the power brick is shutting itself off. Or maybe something in your laptop is getting too hot and it's shutting down to protect itself.

 

Okay thanks for that, but more important question is why is turbo short time power limit ain't setting?

Hi!, somebody knows what exactly does Turbo Boost option whe you pressed, i mean programatically, it's a cmd script that change current policy, or set option in regedit?
