The ThrottleStop Guide

Humm… this might be a stupid question, but can I undervolt the TURBOboost with ThrottleStop like with Intel XTU? 'Cause I don't want to have both TS and XTU installed at the same time.

I see something in the TPL window, which is theoretically about that. Maybe that “Package Power Limits”?

But then I'm not sure what numbers I should change and what is my range.

Thanks in advance!

 

Update: i checked MSR 0x1a0 with rdmsr -d(unsigned decimal) 0x1a0 before turbo boost got disabled and it gave me 8716425 value and run dota wait for turbo boost get disabled and after it i write to MSR 0x1a0 8716425 value and viola turbo gets enabled again and even though i reach 100c values it never disables , only problem is if i quit the game wait a bit Cpu cools and i enter the game again, after some time especially at around +85 degrees celcius range turbo gets disabled again and im having to rewrite msr values and it works. i can automate it with a bash script though do you have any idea how to fix it permanently?

 

I think RWEverything is the fix to all throttling. I look forward to when PL2 pops up again and post photos of the Memory tab so it can be manipulated in a way to stop throttling even on idle which I'm experiencing, so frustrating but a quick shutdown and startup stops PL2 for a few more days till it comes up again...

 

are you sure that cause is the pl2? I guess i felt that something like time limit or power limit too.

 

I'm not sure but I'm following the advice of sir unclewebb I have tried everything else like uninstalling intel thermal management program/driver but I still get PL2 flag intermittently. I'm not sure what else to try except using RWEverything as advised by unclewebb.

 

interesting as long as i use throttlestop pl2 doesnt bother me.

 

So I don't even need to bother turning TS on when the PC starts? It's already set up to start automatically, but I thought I had to turn it on to have settings like SpeedShift to work with the value I set on the "Settings" box in the main window.

-100mV Core/Cache seems stable for everything.

Should I bother undervolting iGPU, SA and Analog IO?

Thanks again!

 

What does "turn on" button actually do?

All undervolts and speedshift epp settings work even when the button says its turned off.

Legacy button that doenst matter on modern chips?

As I suspected. Thanks!

 

I did some testing and with a -100mV undervolt my 8250U doesn't exceed the 20W limit when turbo ratio is set at 29x. That's nice and keeps the processor running way cooler. That's a 603cb on Cinebench15.

Also, it could be a nice setting for a "gaming" profile, since the heatsink on this Inspiron 7000 is shared with the MX150, so that should give me some headroom for the GPU.

With a 30x multi it exceeds 20W for brief moments and end up getting in and out of PL2 Power Limit, oscilating between 29.5~30.0 multi when that happens.

I'll do some testing with -110mV, it would be nice to have 30x locked below 20W.

If I want, is there a way to set PL2 to 20W (making it stick)? It doesn't make much sense to make my CPU go up to 34x if it can't sustain that and it will only harm GPU performance.

 

It just PL2 flagged just as I started up Windows and I had the AC adapter plugged in before turning on the laptop. Here is the Rweverything screenshot of FED15900.



Apologies in advance for the unclear photo. Thanks unclewebb.

 

When I shut down my computer it refuses every time and I have to force shut down, how to fix that?

 

It is not too bad. At least I can see it. If your keyboard has a Print Screen or Prt Scr button, push that and it will take a snapshot of your screen. Open up Paint or a similar program and push CTRL+V to paste the image from the clipboard into your Paint program. Do some cropping and there will be no worries about a blurry screen.

Just to review, a yellow box means that some throttling has occurred since you booted up and a red box means that throttling is in progress. Your screenshot shows a yellow PL2 box so at least your CPU is not currently throttling. It is not unusual when first booting up for some or quite a few of those flags to show evidence of throttling. My theory is that maybe some registers are not set correctly until later on during the boot up process so the CPU records some throttling but it might not mean too much at this early stage. My laptop shows a bigger throttling mess than your laptop shows after first booting up.



In your screenshot, the two power limits in the MMIO registers show that the long term is set to 47 Watts and the short term is set to 56.25 Watts. Both of these values are as expected. Nothing unusual. Next time your CPU is stuck and it is constantly showing PL2 glowing red, open up RWEverything again and take another screenshot. The values in that memory location can change at any time so perhaps something in there will show up. If FED159A0 and FED159A4 look exactly the same then it is probably a value that is not set correctly in the PECI power limits. That would either be a bug or just bad design and I cannot think of anything a person could do to solve that problem.

I have heard that in the Power Options - System Settings that the Turn on Fast Startup option can cause problems for some people. Try disabling that and see if it makes a difference. My Windows 10 computers do not have any shutdown problems at the moment.

 

@unclewebb something i've noticed with speedshift, because it is not tied to individual profile but affects all profile in general, sometimes when I speedshift on with values min/max (min:1 and max:15 as an example), I find that I have to manually go into TS and change the max value every-time otherwise profile will not work.

in the example of min 1 and max is 15, profile 1 sets to 1.5ghz underclock and works just fine, doesn't go over 1.5ghz. but if profile 2 is set to say 4ghz, it'll stuck at 1.5ghz until I manually change that max value again to say 40+, if I did that then profile 1 will exceed 1.5ghz, making individual profile settings pointless.

is there a way to incorporate speedshift into each individual profile to fix this issue?

 

Thanks so much for the reply back unclewebb. The thing is the PL2 was throttling and flashing red/yellow every 2 or 3 seconds when RWEverything was open on Memory tab, not only yellow above. it does it continuously even when i dont have anything open and i just navigate through Windows Explorer. It was throttling for a very long time and the only way to stop the flagging was to shutdown and startup the laptop again. Its a very intermittent issue though and only get stuck of PL2 flag flashing red every 2 or 3 days. I use my laptop everyday. Ill take a screenshot next time when i get PL2 issue again. Ill take a few photos of the different memory locations so you can see the different figures. Thanks so much for all your help.

 

I originally thought about adding this feature to TS but so far there has been zero demand for it. Maybe this winter it will move up on the things to do list.

The next TS version will have adjustable IccMax on a per profile basis. This will give users an indirect way to fine tune max CPU power consumption for each profile.

If that is the case then the two power limits in the memory area do not appear to be the cause of your problem. Your laptop manufacturer has decided to do some throttling when idle. No idea why. They should not be doing this. My best guess is that an engineer set one of the many power limit registers inappropriately. I am not sure how to solve this problem.

I was helping another user today on another forum and the engineers only set one of the two turbo power limits in that memory location. Nice instant throttling scheme. They get the bonehead award.



To make sure these values are not changing, I would set the first group of numbers on the left side to 00000000 and then I would set the second group of numbers on the right side to 80000000. This will lock and disable this power limit until the next reboot. Just double click on those numbers to edit them.

 

Hi unclewebb, If this is the case would it be worth RMA'ing? Or will the other replacement M.B have the same issue most likely? Please advise or should I rather not bother because a shutdown and startup fixes the problem and the PL2 is intermittent so it's likely not a hardware issue? Thanks unclewebb

 

how to run this auto with win 10 start ?
or where is option ''start program when windows starts'' ?

 

You know, this entire thread could probably be shortened to about 50% if people bothered to read and search around on their own.

The developer of this program himself wrote an entire guide for it... literally on the second post of the first page.

We are all here to help, but in the future, please at least make some effort to search around yourself before posting such questions. The search button/bar exists for a reason. Sorry if I seem hostile, but it's just that I see this behaviour all the time - especially here and xda devs,

 

Jst done it

 

But but but .. I did it but how to auto run it in system tray? it starts but in taskbar and I don't want it in taskbar I have to manualy open it and hit X
I knoow but in year 2018 these basic things SHOULD be already IN the program.. and not messing manually ..you know what I mean ..

edit : it works now..
weird i untick task bar and even saved it and didn't work but now works ..
great thnx ..
Please program maker try to add this as standard in new version .. in options
many softs has it already and loong time
thnx

 

I left this feature out of ThrottleStop on purpose. Setting CPU voltages can be dangerous. Best to slow down and think about what you are doing before adding any program like this to your Windows startup sequence.

The Task Scheduler works well. Learning something new is a good thing. Here is a link to the official guide.

How To Start ThrottleStop With Windows
http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/#post-6865107

 

Would sudden shutdown of games be a indicator of too low undervolt? I have problems with Tomb Raider and Dark souls 2 which both randomly shut down after anything from 2 minutes to 10 minutes and jump back to Windows without error\freezing\bsod.

I`m currently running undervolt on i5 8400 (-170mv on core and cache which seems stable after a couple of hours with prime95, on -185mv it crashes, on -180mv it`s stable so -170mv is with a bit of buffer).

My GPU, RX 580 is underclocked (1300MHz) and undervoltet (set at -150mv, -180 crashes, -170mv is stable so I have put in a buffer). I used Unigine heaven as test and ran it for 3 hours at -160mv before I set -150mv.)

RAM is at XMP-profile of 2666 CL16, it is rated for 3000 cl16 so that should be fine as well, ran mem-tests to check for instability there and found none even at cl14.

I have ran each individually with both others disabled and they are stable by themselves, but when I bring them together somethings not right :\ My GPU lost 4% performance and use 29% less Power, runs more silent and cooler, my cpu runs 12C cooler, silenter and uses 20% less Power so I really wish I could keep all settings :\

 

Alright guys. I've got a brand-new Dell Precision 7530 with an Intel Xeon E-2176M running under the hood. It's great when plugged in

The issue is that I get horrendous battery life, even with the 6-cell, 97-Whr battery, and performance is very obviously neutered. My idle power drain is something like 30 W; I'd love to get it down to something like 5 W or so, give or take.

What can I do? Thanks in advance.

 

I thought about that understand now.. all work fine now
Thnx just wanted Speed Shift to be enabled..
How far can I push 6700HQ to the limits? is it overclockable ?

 

That will depend heavily on two things - whether you have optimus, and your background tasks. A laptop draining 30W on idle is horrendous. Sounds like you don't have optimus enabled. Return that laptop now. Mine draws 3.5W whilst fully idle (no background tasks), 1.7W with the screen off, and averages 5-6W when doing my school work. May I recommend trying out my battery life guide in my signature?

5W... Yeeeaaahhh not happening. That's 97/5=20hrs of battery life. That's more like ARM on Windows, which is clearly no substitute for your mobile workstation,. (Which probably cost an arm. HA!) How many hard drives, ram sticks, etc do you have? Screenshots of TS, HWInfo etc pl0x!

 

Thanks for the reply. That guide looks extremely comprehensive; I'll take a peek at it.

Heh, perhaps I was too ambitious. I'd be happy if I reduced my idle power usage to somewhere between 10–20 W, ideally.

Anyway... I have two M.2 PCIe NVMe SSDs, one un-initialised; the other is my system drive. One 8 GB DDR4-2666 CL19 SODIMM. Here's a TS screenshot with nothing going on, and no undervolts performed:



Here are HWiNFO screenshots:




HWiNFO was reset after unplugging the notebook, so the min-max values are all during discharge.

 

I suspect you may have a task or two running. Check the task scheduler to see what might be using CPU cycles.
Best,

Joe

 

So far, I have not found any way to overclock the 6700 HQ. However, undervolting is definitely helpful - especially in a laptop like mine where heat sink capacity is shared with GPU. By running ~ 140 mv undervolt for CPU and cache, I can run full speed (31 x on all cores) indefinitely without exceeding 90 C.
Best,
Joe

 

I can't find any app that's running at all in the background. I think this needs more investigation.

 

There's an easy way using schtasks. Simply copy the path where TS is installed and the scripts does everything. Follow this link below.
The ThrottleStop Guide

 

HQ = Not overclockable

 

According to one of the screenshots, the battery drainage rate is 18W, not 30W???. The Throttlestop screenshot shows the CPU using 8W onidle. That leaves 10W for everything else, which sounds about right on an unoptimized system. Your GPU clock speed is reported as 0MHz. Unless it is an unsupported GPU, it is probably off, which is good.

Your C states are horrendous too. A CPU using 8W on idle is ridiculous. Ideally, you should have your C0% at less than 1% on idle. Over 80% of your CPU package should be in C7, 8, 9, or 10. All modern (post haswell) U, Y, HQ, and possible HK CPUs can idle at less than 1W. Idk about your Workstation CPU, but 8W is excessive. There is clearly something running in the background.

 

Your screenshot shows that your CPU is spending an average of 8.1% of its time in the C0 state working on God only knows what. You have 12 threads available so here's the math:

12 X 8.1% = 1 X 97.2%

Therefore, you have the equivalent of 1 thread running at full bore almost 100% of the time. You definitely have something or multiple things running in the background on your system. The easiest way to increase battery run time is to get the crap off of your system.

Open the Task Manger, go to the Details tab and click on the CPU heading to arrange your tasks by CPU Usage. There has to be something in that list that is preventing your CPU from being idle. I get into forum arguments here there and everywhere every day about this subject. People think I am crazy but I guarantee you that if you take the time to get the reported C0% under control, your battery run time will immediately increase.

Here is a 2 core CPU with both cores averaging 99% in the low power C7 state. That is how to save power. With 6 cores available to process the Windows background tasks, you should have no trouble equaling or beating this.



Does your laptop use Nvidia Optimus? That puts the Nvidia GPU to sleep when not needed. Some high performance laptops disable this feature which sucks a lot more watts from the battery.

 

What did you say again?

 

93.71 MHz above max turbo boost??

 

Yup Overclocked through BCLK nothing is impossible as long as you have BIOS fully unlocked with knowledge .

Still trying to go higher but there's too much of stability issues so my maximum is 102.7 Mhz without causing any kind of stability

 

If only my BIOS was unlocked... my BIOS is basic to nothing. I really dont mind though as long my temps and CPU dont throttle while gaming I'm happy

 

Hey there. i need help with my CORE i7 6500u (Dell Inspirion 17 5758).

can you please help me set throttlestop to the proper settings for my laptop?

the problem occuring is: 'charger plugged in not charging' error, which causes my laptop to throttle and go very very verrryyyy slooooow.

i followed some online guides but want to make sure its set perfectly for my laptop, because it still doenst seem to be working 100%

in the meantime ive unchecked BDPROCHOT, and it shows yellow now in the Limits check.

what other parameters and settings should i do? (sorry if you already adressed this partiucular laptop settings in a different post, i couldnt find anything)

thank you

 

Throttlestop wont open anymore getting "Could not open winring0.dll" error, anyway to fix this? I downloaded throttlestop again and deleted old one same error. my 8750h throttling 3.9 to 2.2 without ts some games became unplayable again

 

This is actually a very complicated issue to resolve. Some folks pointed to Windows Defender not liking the .dll file. I came across this problem after installing both Intel XTU and the EVGA GPU software similar to MSI Afterburner. I discovered that the EVGA software shares resources with other windows components. Even after deleting that software, I ran into the error again and again. Only solution was to keep that software, uninstall Throttlestop and reinstall again.

 

damn i just deleted evga today and using msi now but i dont want to install evga again lets see if i can install and keep it disabled. Thanks for the quick reply

 

This seems to be a common problem on many Dell laptops. Disabling BD PROCHOT can help get the CPU back up to its rated speed. I have no idea if your laptop will be able to charge. You have a low power U series CPU. As long as your laptop can charge your battery, disabling BD PROCHOT is not going to hurt anything.

Another good fix is to install OpenHardwareMonitor. Start that program and then ThrottleStop should start just fine. It also uses the WinRing0 driver but it is hidden within some other dll file.

 

@unclewebb, thanks for the reply. First off, I legitimately couldn't find the rogue CPU-hogging program. The C0 value fluctuates between 2% and 12%, but whenever I open Task Manager to check, I can't find it. For now my total system power draw has been brought down to around 15—20 W.

Second, my notebook comes with a multiplexer, and I can choose whether or not to enable the discrete GPU directly to the display, or not. These screenshots were all taken in Optimus mode.

I've installed ThrottleStop and let it use Profile 1 (Performance) while charging, and Profile 4 (Battery) while on battery. I'm not sure what setting I've set, but now my computer lags inordinately while running on battery power. Attached are screenshots of my various profile settings. I haven't scientifically measured the total runtime difference yet before and after ThrottleStop, and ideally I'd like my computer to sip as little power as possible while idle, but quickly rise to up to a medium-power state, depending on the workload. Furthermore, I've also experienced two BSODs with the error code ATTEMPTED_EXECUTE_OF_NOEXECUTE_MEMORY.

Here are my TS screenshots, appropriately labelled. Am I undervolting too much? At some point I even noticed rubber-banding of the cursor; this problem went away altogether after I plugged in or switched TS off on battery power.

 

Dell ships with Adaptive Battery meter that prolongs battery shelf life by charging battery 50/60/80/90% just like FlexiCharge. By default in BIOS its set to Adaptive/AC usage.

 

Particularly with Intel's "enhancements" to their GT domains, mainly tuned for functions such as QuickSync.
Features such as Low Power Encoding (firmware dependent for HuC and GuC activation) stem from these changes.

 

I suspect that there's some driver issues you are experiencing because depending to what I saw on your previous posts and in your previous screenshots.. your cores is going to the lower states perfectly (still needs to look for it due to lower percentage that is spending on C7 states) but your major problem is your Package C States it doesn't go lower so this is usually a sign of driver issues causing it not going to lower C States.

Try to avoid the generic ones that MS is providing it because usually it doesn't have the power saving capabilities for example... installing SATA AHCI Controller drivers from Intel or newer Intel GPU drivers or WiFi & Bluetooth drivers from [Realtek or Broadcom or Intel] or installing Intel chipsets even Audio drivers [Conextant or Realtek] or Touchpad drivers [Synaptic or Elan] or Keyboard drivers causing those Packages C States not to go to power savings while not in use.

SSD may cause this too as well due to problems related to APM [ Advanced Power Management] due to SSD in default is working in performance mode and it doesn't power down while on idle .. you may like to look at your APM settings through CrystalDiskInfo for example...


And maybe your windows power options is not using the correct settings like... for example on my laptop I put those settings to enjoy lower power consumption while on idle..


Too many things is related to your problem unfortunately but I tried to list things that you should look at it

I hope I helped

 

I saw "Maximum Power Saving" in the screenshot.How is that wrong?Pardon me if you seems that is stupid.
Windows Power saving settings are a mess.
And your ASUS... How the hell man?!
Would you ever write a guide about that?Really interesting.

 

I always have that turned "Off" while plugged in and set to "Moderate Power Savings" or "Off" for Battery. I dont know if it's true but I heard if its turned to Maximum power savings it effects the performance of the CPU while gaming?
