The ThrottleStop Guide

Yeah I just see "IMG" with an "Icon"

 

unclewebb, would that Lenovo be the Flex 4 1480 by any chance?

 

Hi, Can you please give me settings for my laptop. I Have Acer Aspire V Nitro VN7-792G with 6700HQ proc and NVIDIA GeForce GTX 960M.
When battery is below 40% laptop is very slow. I use your default settings, just uncheck BD Prochot (read on some forums to do that) Not want to clock just want speed as declared.

Acer works very well now, but I run your software just when battery is low. Is it safe for me to run your software all the time, at battery and AC as well?

Thank you
Kind regards

 

I tried Powercut feature on Lenovo g50-80 with i5 5200u with TDP=15W and still hits TDP limit. It just peaks to 13W even on wprime 32m[ 4T=18secs 8T=17secs] with cpu temps 55-56C.

 

You don't have the details of your laptop in your signature, so I cannot tell if you have a separate GPU. It is common for a laptop with a QHD screen to have two GPU's - the Intel one on the processor, and a separate, discrete (often Nvidia) GPU. Most are set up to default to the intel GPU for most things. - however, an application that is sending QHD info to the display will stress the processor and the underpowered Intel GPU simultaneously. If you do have an Nvidia processor, you can set the driver to use that processor for HD video applications and games. Good luck, Joe

 

No. It was the Lenovo E570. It has the Core i7-7500U, an Nvidia GTX 950M and I added a Samsung 960 EVO M.2 drive. Not a bad little laptop after you do you some undervolting and a few other minor tweaks to it. If Lenovo did the tweaks before shipping it and offered some improved screen options, they could sell a pile of them. I think I was at default voltage when it was running LinX at 28 Watts. I was trying to make it throttle but it was being a real trooper. With a -100 mV undervolt, it dropped to about 22 Watts. Any normal load was a lot less than that.

Probably but no one here knows the answer to your question. If you bought me a 1000 Acer laptops of the exact same model and I tested them using ThrottleStop for a few years, I could see how many failed and give you a better answer.

All I know is that for more than 6 years, thousands of people have used ThrottleStop to help fix their throttling laptops and there have been virtually zero complaints about laptop failure due to using ThrottleStop. If I owned your laptop I would disable BD PROCHOT but it is your laptop so you have to take responsibility for it.

Just remember that most gaming laptops are not designed to be used for gaming while running on battery power. Very few laptops have batteries that will allow an Intel 4 core CPU and Nvidia GPU to both run at their full rated speed while running on battery power. Using ThrottleStop to try and force this to happen while on battery power could permanently damage your battery or possibly cause a battery fire. That would not be good so use some common sense when using ThrottleStop.

 

Throttlestop can't force a dedicated GPU to run at full power anyway on battery. The dedicated GPU gets spammed with "Temperature Limit" (even at 40C) and "Power limit" and VREL limits and capped.
Not sure about CPU.

 

my x9100 already come and installed on my laptop (using BSEL mod)
It can boot up...
max multiplier is 18 (3.6 Ghz) in 1.2875V , its stable in prime95
It will BSOD when I try to increase voltage to 1.3V++ so its not possibly to get 4 Ghz

my laptop multiplier only reach 6 when laptop adaptor unplugged
I have a question, Can I make it multiplier stay at 18 althought laptop adaptor unplugged?

here the pic of my problem

Thank you for answer. My english is very poor. I not play games at all. Just run throttlestop when battery low (under 40%) and procesor is then slow about 800mhz. And then I work some ushual things, photoshop, internet and so on... I ask you can I run throttlestop all the time (not playing games, just for regular things) when in AC also, not just on battery?

I asked just becouse warning at start of program.

Thank you in advance

Also get a error follow your insttions to put throttlestop in start programs (win 10)... I try many times, step by step and allways got some kind of error.

 

You can pin TS to start menu and after startup simply click on the icon to get it started, that's what I do.

 

Thanks, I allready do that, but wandering why can't set it in start menu.

 

If you have W8 or W10, you pin it to Start. On Win 7 you can pin it to taskbar.

 

To get throttlestop to start automatically I added a task scheduler entry to launch it at logon.

Yes, thanks, this is work. Before was set "at system startup" and nothing hapened.

 

Maybe. Try clearing the BD PROCHOT option and see what happens. Keep in mind that ThrottleStop will not set your CPU multiplier or voltage correctly if you are using the Windows Balanced power profile. Switch it to High Performance. The reported VID voltage displayed in CPU-Z and displayed on the right hand side of ThrottleStop should be exactly the same as the requested VID voltage that is selected on the left side of ThrottleStop. The Balanced profile will ignore ThrottleStop so these voltages will not be the same.

The Task Scheduler is the best way to start ThrottleStop with Windows.

@Vivekananda - I cannot predict what will happen to your laptop if you use ThrottleStop. Using ThrottleStop or not using ThrottleStop is your choice.

 

Task scheduler didn't work for me.

 

Mr Throttlestop and others, a little contribution.

I've got the Dell XPS 13 9360 and I'm a Linux user ;-) You mentioned in your great post http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/page-497#post-10343728 that Linux user merely have to write a 1 to MSR 0x770. Luckily no need to do scary bios things, it seems - you can simply install msr-tools and use that. https://01.org/msr-tools

As you can see, it seems that on my system (running openSUSE Tumbleweed, a rolling release Linux with extra kernel repository with 4.12.0-rc5) speedshift is already enabled.

That's good news, I suppose. I would love to hear any tips or thoughts on how I could verify this but at least it seems Linux either changes the setting automatically or Dell's bios from May (which I installed some days ago) enables Speedshift.

 

Overclock is greyed out in FIVR, and Set Multiplier doesn't do anything for me. Non-Turbo Ratio is at 0. Is there a BIOS setting I need to change? (Have K chip)

 

I am noticing that even when ThrottleStop is "Turned Off", Turbo Boost can be enabled or disabled. Is this an expected behavior?

 

Turbo Boost and throttlestop are not the same thing. You don't need throttlestop "turned on" to change FIVR and voltage settings. @unclewebb can correct me if I'm wrong, but I think "turning on" throttlestop is for doing things like controlling speedstep, EIST, CPU multipliers (via the "set multiplier" area, not in FIVR; sandy and ivy bridge CPU's will respond to this), and clock modulation, etc.
The other settings are controlled by C states and registers. Of course I'm probably wrong about something here....

 

Oh, what exactly does the Turn On button turns on? Also, is ThrottleStop like XTU where changes are saved in BIOS?

 

On my 2600k, turning on throttlestop allows me to change the CPU multiplier and Clock Modulation settings and change those after using the checkbox. If I "turn off" throttlestop, the settings I made still are active, but I can't change them anymore without turning on throttlestop again. The same goes for speedstep and EIST.
I can't speak for newer CPU's. On my 7820HK laptop, I use throttlestop as an undervolt and overclocking tool with profiles for battery and AC power. I don't think CPU multiplier and clock modulation works on Kaby lake boards, as that was moved to the fully integrated voltage regulator. It may still apply for turning on speedstep, but the minimum and maximum CPU speeds are controlled via the power settings in control panel, afaik. Instead, you can just use speed shift and force the maximum or minimum clocks you want with speedshift, as well as how aggressive you want the underclocking to be at idle (to force max clocks at all times, set speed shift max mulitplier to your max turbo ratio, and then set speedshift to 0).

 

From Linux Kernel 4.10 and upwards, you have native support for Speed Shift 1 and 2.0. Its HWE in Linux. There is a drawback though in default balanced mode of HWE, your turbo speed will be cut by 20%. http://www.pcworld.com/article/3173618/linux/kaby-lake-is-unleashed-with-kernel-410.html

 

Wow so many settings. Does the "Turn On" button really need to be clicked for settings to take effect? I mentioned Disabling Turbo Boost did not require that button to be clicked. Is there documentation about what settings take effect when the Turn On button is pressed? Thanks!

 

What K chip? If you have a question, post some pics of ThrottleStop so I can see what CPU model you have, what version of ThrottleStop you are using and how you have ThrottleStop setup.

For the record, when properly setup, Set Multiplier continues to work on my Kaby Lake desktop CPU. Set Multiplier will not work correctly if you are using the Balanced power profile and it will not work at all if you have Speed Shift enabled.

Also for the record, starting ThrottleStop by using the Task Scheduler has worked for me on every computer that I have tried it on since Windows Vista which came out 10+ years ago. If it does not work for you, you have not set it up correctly.

Turn On - Turn Off controls 3 things; Set Multiplier, Clock Modulation and Chipset Clock Modulation and that is all.

There is now. Read the above line.

ThrottleStop is not like XTU. ThrottleStop does not make any changes to your bios. I think this is a safer way to go. If you need a tool that changes your bios and might get you stuck in a nasty boot loop, go with XTU.

 

Omg thanks. I am glad this is not saving to BIOS like XTU.

 

I have exhausted every other option to getting reasonable performance out of my Lenovo Miix 2 11 except for Power Cut. It works fine except that any time it is activated I need to restart to get the lower TDP values reported. After a suspend, the actual TDP values are reported as normal again and I need to restart to get Power Cut working again. Has anybody else had this issue? Is there any information I can find or provide that will help me understand why it isn't working as intended?

 

This is a known issue with Power Cut on the Lenovo Miix 2.

Someone else reported the same issue just recently.

That is by design. PowerCut has to be enabled manually. It cannot be enabled reliably during a restart, especially on a low power device.

The only way I can make this work better on your specific laptop is if I have your specific laptop to play with. Without access to hardware, that is the best I can do. Maybe ship your Miix back to Lenovo and tell them they can have it.

Edit - My mistake. It looks like the only other person to complain about this recently was you.

There have been no changes to ThrottleStop since then.

 

I have the 2017 MBP 15 with the i7-7920HQ. Regret to say that I cannot adjust voltages with TS or XTU

 

Did you install intel chipset driver software and MEI driver on apple bootcamp?

 

@unclewebb I have a 7300hq and i only want to undervolt. Do i have to disable speed shift for that to work or that only matters for multiplier manipulation?

Thanks for a great product.

 

Enable SST.

 

Hi. You mean enable speed shift -epp? SST was on by default for me

 

Yes the same. 128 is balanced mode. 0 will mean max performance and 255 means max power savings.

 

Ok will do. Thanks.

 

I installed the drivers that apple does automatically but running intel driver update didn't show anything as available

 

Most likely Apple EC is rejecting the values. Did you try checking your offset values HWMonitor and ThrottleStop?

 

Yeah, nothing sticks. TS shows no offset and XTU just greys out the option

 

Ugh -160mv undervolt and system lock up. Windows rebooted with a bluescreen and kept locking up even though I did not have TS run at startup. Is it possible the cpu registers still had the undervolt setting. I had to force shutdown the laptop to get it to work.

Always configure AC and battery options. If you run into issue and I simply switch off AC, to trigger battery mode and all works. Which CPU are you undervolting?

 

This is the i7 7700HQ


Sent from my iPhone using Tapatalk

 

Try -120mV

 

I was able to hit -150mv stable. Got lucky I think.

I thought -150 then I switched back -120 for safety reasons.

 

Hey guys, just looking for some advice. Got my new laptop in my sig running an i7 7700k. Are there rough estimates of what I should be able to start off with as far as undervolting goes? I have it running at 4.4GHz and it was idling upwards of 50-55C when I checked it today which is a little higher than I would like but everything was stock. This is my first time really using TS. I turned the CPU cache and CPU core down -95mv and ran Prime 95 for a while and no crashes, everything seemed fairly fine and stable. Just trying to get a rough idea of what I might be aiming for as a baseline

 

Will have to go to -140 now, SC2 threw me a bluescreen after exiting the game. Amazing how all other stress testing app passed without issue and sc2 blows up.

 

Does anybody know what is the effect of undervolting the igpu of I7-7700HQ when the igpu is not used at all? My laptop only uses the discrete GPU (Nvidia GTX 1060).

 

Speed Shift is separate from under volting so you can under volt with SST enabled or disabled.

Anything is possible. Windows has a hybrid boot feature where the CPU is usually not reset to its default state. If you ever run into problems, best to completely power down and do a full boot.

Never thought about doing that before. That is great advice.

It sounds like you already have a pretty good baseline. CPUs are unique. Run some stress tests and adjust the voltages. This would be a boring hobby if everyone was using the exact same settings.

Good question. Do some testing and let us know if it makes any difference. Does HWiNFO report any power consumption for the iGPU? If it reports 0 then reducing the voltage is probably not going to make any difference. My laptop uses Optimus so I cannot help you with your question.

@Eason - If ThrottleStop is not allowing you to adjust voltages then I doubt it will ever be able to adjust voltages on your laptop. Not sure why exactly but it sounds like something has been locked by the manufacturer. It might be the end of the road for TS.

 

It is interesting. It only shows the temperature of the igpu and that's it. I don't see any sensor measuring power consumption for this.

 

Yeah. Thanks, Apple.
