The ThrottleStop Guide

@Ultrax5 for TDP limits I've noticed that they assume high level over 47w when the battery reaches 100% (ac plugged ) or when I active conservation mode for battery in Lenovo settings

 

Valid point, actually it doesn't go past 47W until the battery stops charging. Conservation mode limits the charging level to 60, so it's not charging, so it's using the 58W short ppl. The thing is even if it gets to these 58 Watts, the limit can't be increased further(or, to be more clear, it can be increased but only on certain circumstances and I'm yet to know what causes this...)

 

Great to see a BGA CPU running wild.

The wait is almost over. For those that do not feel comfortable running a modded bios, there is hope on the horizon. I found some room in the FIVR window for the new PowerCut feature and final testing is looking good.



A Core i7 running 8 threads of the TS Bench with power consumption being reported at a meager 1.6 Watts. No more TDP throttling.

Thanks Dufus for introducing me to this wonderful new feature. Users around the world are going to appreciate PowerCut. Hopefully a full release will be ready tomorrow.

 

Eagerly awaiting for it

 

Hi !

I have the exact same issue and couldn't find a fix. Everytime I unplug AC, ThrottleStop exits. Is there anything to change in the settings to avoid this ?

Anyway, many thanks to Uncleweb for the amazing job !

 

Maybe something introduced in 8.0b7? First I've experienced it. RestartonCrash has the problem that it starts it non-minimized.

 

@hdneo I managed to mod the bios and I mouthed the multiplier up to 42 (not 80?). However how have you set the voltages (offset or fixed ? thank you very much!

 

Edit - The DC Exit Time option is the one that forces ThrottleStop to exit when you switch to battery power. Do you guys have that one checked? I am not having this problem on TS 8 beta 7.

I think the 80 multiplier is the official maximum for the unlocked K CPUs. Looks like you guys are creating your very own line of unlocked processors without having to send Intel any extra cash.

Good work.

 

Indeed it was checked, my bad... Thanks for this !

do not set any voltage in bios it will be semi bricked and you must do recovery bios.
if your bios has advanced menu only enable extreme overclokcing and set turbo core voltage @ adaptive 1200 mv. aslo set current to 120A in ThrottleStop 8.00 Beta 7.
Your notebook will be too hot and you could not complete long bench (BSOD or Reset).
this work is only for interesting, not for daily using.
for set Multiplier only use ThrottleStop 8.00 Beta 7.

 

during bench package power show 1.6 Watt.is it real Power?
or something fake power to overcome TDP throttling problem.

 

A Core i7 cannot run fully loaded while only consuming 1.6 Watts so it is definitely fake. The PowerCut feature tricks the CPU so the CPU reports that it is consuming far less power than what it really is. It is a bug within the CPU so all monitoring software will report the same uber low power consumption. If the CPU thinks it is only consuming 1.6 Watts then there is no reason for it to start TDP throttling. Full turbo boost should be available as long as you do not run into some other limit like temperature or current consumption.

This trick works on my 4700MQ which is using micro code 1C. This feature is probably going to be able to trick a LOT of 4th and maybe 5th Gen CPUs. Will Intel be able to come up with a micro code patch for this? Maybe, maybe not. It might not be worth their time.

 

Is there a microcode version to use with Skylake that will unlock those multis?

 

In the XPS forum, we've been discussing the battery life: http://forum.notebookreview.com/goto/post?id=10211699#post-10211699

A user with a 6700HQ claimed he doubled his battery life with TS using the settings in the above link.


However, I've got a XPS 15 with a 6300HQ and I've not been using TS because the "power saver" option limits my clocks to 1300mhz on the 4-core 32m TS bench. It just won't let the clocks go up with "power saver" on. With power saver off, it seems to work fine (but it will keep clocks pegged higher and waste power).


But if I uncheck "set multiplier" and the power saver option goes grey, it works as it should.

 

Good work Unclewebb, I've been using Throttlestop since about 2010 if I remember rightly! This unlocking of TDP limits and unlocking of multis using PowerCut/Throttlestop is very interesting, will any of that work for 2nd Gen i7's - the Sandybridge CPUs, I'd be interested to see if my CPU would unlock (i7-2630QM)? (I've read a fair few pages of this thread but couldn't find an answer).

 

Good morning everyone,

Unklewebb, as always thank you for your ongoing development. I think i speak for everyone who's used your program when i say we are lucky to have you.

I use throttlestop primarily to extend battery life on the 6700hq yoga700. I achieve excellent undervolts that make a significant difference. It also lets me drop about 10c off the cpu when gaming which is phenomenal.
I just updated throttlestop because it told me the beta ran out of time (i think i was on beta6). However, now i'm running into an issue where the cpu speed will ramp up to 100% (no turbo) permanently regardless of cpu load. I have a the set multiplier box checked and limited to 14 and the power saver checkbox enabled as well. I'm surprised that the cpu can ramp up above the 14 multiplier limit i set.

This has happened once when coming out of sleep and once from a fresh boot after i changed the windows power settings to power saver and then loaded up throttlestop.

Sometimes i can clear the bug by shutting down and restarting, sometimes it persists. I don't understand.

Here are the settings i'm currently using in throttlestop

Thank you for any assistance.

 

@mikel0181:
It seems throttlestop doesn't report multiplier correctly for (some or every?) skylake CPUs, as i have the samle problem here (i5-6200u). But: use another tool to check on real cpu speed (hwinfo or even taskmanger) -> al least in my case everything is working fine and the cpu is slowing down correctly. I hope uncle web may fix this some time.

Sorry for going a little of topic, but any news an Skylake/Broadwell unlocked microcodes?



P.S. Thx Uncle Web/Dufus/supporters btw for this great tool. It's really helping my acer v3 13' with an overpowered i5 5257u staying on the ground and not rising up like a helicopter.

 

I wish that was the case here. Task/performance manager also report the clock speed getting stuck at 100%. Power use increases and fans rev up more frequently.


This didn't happen on beta 6. Yesterday i had some luck rebooting and launching throttlestop with everything working as expected. Today it seems that even after a shut down, charge, or restart, every time i start throttlestop now the CPU revs up to 100%

The clocks stay 100% after fully exiting throttlestop, complete reboot fixes it but then i can't run throttlestop again or the problem returns.

Will try to uninstall throttlestop and install the lenovo bios update to see if that can reset all the settings and then try throttlestop from scratch.


Looks like its working again. changed fivr --> non-turbo ratio to 26 and checked the lock option

tried that before but it didnt take. it did this time though. will forgo the bios update and reinstall unless this happens again.

 

@unclewebb

Hi,

would be really great if you could give me a hint, where to look for the MSR register for the following values of throttlestop:

-Core Offset Voltage
-iGPU Offset Voltage
-System Agent Offset Voltage

I really like to bring the ThrottleStop Values from my Windows machine to my Linux system.
But so far I wasn't able to identify the correct MSR address at all.

So, are there chances that you could provide a hint at which MSR I should keep an eye on while manipulating these three values by ThrottleStop?

Thanks and regards,
Kontr-Olli

 

I came across this before. In turbo ratio limits, simply lower them so that they are all 14, and it should work fine.

With that said, are you sure -200mV is a stable undervolt for you? That is an absolutely MASSIVE undervolt.

 

Yeah, luckily prime 95 stable if limited to 14x multiplier. Not stable at 26x if running anything more than microsoft office. I'll look into lowering the turbo rate limits the next time the issue comes up. I was able to resolve it spontaneously by changing the non-turbo limit to 26 and locking it. Hope it sticks, it didn't before.

Thank you.

 

I'm sorry if this problem had already reply but i wanna ask .
I have recently set my turbo ratio limit to "2 cores active -27" but when the cpu use all of its cores,the speed isnt change and still under 2.5Ghz.

Thank you.

 

Anyone here tried ServiceEx to run TS as a background service?

 

Try using Svc by Nick Rozanski. It can be found here.

You will have to configure a service along with an INI with a call something like this:
srvstart.exe ThrottleStop -c C:\ThrottleStop\ThrottleStopService.ini

Note that the version of Svc that I use doesn't like spaces in the file path - maybe there is a newer one that does. *Shrug*

If you poke around in this thread, I think you can find a few other examples. There is also some documentation with Svc.

One small warning: make sure your ThrottleStop settings are stable before you set the service for automatic start.

 

Unclewebb, mine ThrottleStop beta 7 expired (((((

 

No worries. I won't let users suffer too long. Got to go walk the dog first but I will get something uploaded shortly.

 

uncle is there a way powercut could help alleviate the Tskin throttle from the surface pro 4 i7? It throttles due to the chassis temperature that changes the PL1. SP4 uses the i7-6650u.

 

Try it and let us know.

 

hehe once he posts the TS with powercut I will. Or is there a link for powercut I'm not aware of. I tried to do a search

 

Not sure if PC will be included, but the post before yours...

See:
http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/page-428#post-10213010

 

The new PowerCut feature will only work on the 4th Gen and maybe the 5th Gen CPUs. 6th Gen Skylake CPUs are not supported.

 

Nssm (no sucky service manager) seems to work for installing TS as a service. Other apps didn't process executable or weren't compatible with win 10 64

 

ThrottleStop 8.10
https://www.sendspace.com/file/4n3l0p

New Features:
- added PowerCut feature.
- added 4th Gen and up microcode reporting.
- improved Skylake U compatibility.
- C State reporting and SLFM bug fix.

Read the included ReadMe file to learn how to enable PowerCut on your 4th or 5th Gen Core i CPU. This is an experimental feature so your feedback is appreciated.

If you like PowerCut, give @Dufus a big

Edit - VirusTotal is happy, so far.

 

@ unclewebb power-cut dose not work on my notebook. it shows disabled and my microcode is ver 01.

 

Seems to work with i5-5200u. No more PL1/2 on Limit Reasons so far. Package Power goes around 1W at all times . Now i have just yellow EDP marker left. Do you recommend disabling and locking PL3 on FIVR? It says "not used".
Another question, do you recommend changing C7 interrupt response limit on C1 menu? mine is on default, 18.

Awesome work by uncleweb and dufus! Thanks.


The other thing bugging me is the 25 multiplier lock-on when full load, even though i set it to 27 on throttlestop at all times. Well i guess i should just accept that.

 

Too bad. This new release didn't change a thing for my Asus ux32ln. I was hoping to get it ( i7 4500u)to run at 3GHz during load, but it seems to drop down to 27x as soon as both cores are under stress. Before playing with Throttlestop I always thought that it was throttling when it happened, but after a quick read, it seems that it is actually doing what it is supposed to. It's not throttling. It is just running on max multiplier for 2 cores and there is no way around that by only using ThrottleStop. Correct me if I misunderstood.

Only thing I'm seeing in Limit Reasons under load is EDP slowly blinking in yellow. c0 stays on 100% almost constantly. Is the microcode mod my only (or best) option to get it to run at 3GHz?

I tried disabling PL3, but no change. Same goes for powercut. The weird thing is, ThrottleStop reports package power normally when it is enabled, so I don't think that it's doing its thing either, even if it isn't supposed to fix EDP throttling.

Here is a small log from 4 thread TS Bench And a few screenshots showing my current settings.

 

another interesting record: 4.4 GHz on 4710HQ @ 1.3 Volt 96 Watt TDP!
Jump from 50 to 98 after 1 Second! WTF!

Hi,

I have i7-4600U and PowerCut does not work. It says "Locked" and when I flip the tick it says "Disabled". Is there something else I need to do in order to enable it?

It is working now!

 

This throttlestop tool is awesome, thank you unclewebb!
I've been using throttlestop since 2010 to get better temp on 2 of my old fujitsu laptops core 2 duo, overclocking my desktop (BCLK adjusted from BIOS) i5-650, i5-2400, i5-3570k.
One question, is it possible to adjust TDP level limits? Seems like my lowest Package Power Limits setting limited to 60.

 

Running nicely on my Hp envy, i7 4700mq with microcode rev 1e!

 

@ unclewebb power-cut dose not work on my Alienware 17 R2 Intel Core i7 4980HQ. It shows enable and my microcode is ver 12 but does nothing and I still have TDP throttling. Bad luck :-(


.

 

I can confirm that it works in a Thinkpad Yoga S1 with an intel 4500U processor.

Here are some steps that I follow to activate it, as it is not exactly straight forward:

1.- As the readme says, the first thing to do is to put a fixed value in the VCCIN voltage (located in the FIVR tap, CPU).
2.- Readme says that the voltage is recommended to be set at 1.75v approx, but that did not enabled PowerCut for me. I set the voltage around 1.7v and it worked. Then just for the fun of it I put it at 1.45 and it still worked.
3.- Despite PowerCut option saying "Enabled", it will not work right away and a restart is required.
4.- I recommend to lower turbo speeds... as they really make the processor go hot. What I cared most about powerCut is to avoid throttling the iGPU.
5.- Enjoy quite a bit more of power

 

@hdneo How have you unlocked TDP limits? I have unlocked MSR locks in the bios and I've set TDP (long and short) to 70W in throttle stop, but it doesn't working.
Thanks in advance

 

No i could not to unlock TDP yet. i think after downgrade microcode some MSR value dose not set.i also found another problem with notebook panel.
my brightness in windows dose not work. it is disabled and brightness always is 100%.

yes. it seems another thing force to TDP Limit.

 

Two questions:

- How do I tell what version of microcode my CPU has?

- Follwing the readme instructions for using PowerCut, how do I make sure my VCCIN is a fixed value - do I have to change the CPU core voltage to static in order to do so?

 

HWInfo64 should give you the info about the microcode, just click on the Central Processor button and click on your one, the microcode version is listed there.
Actually you can set VCCIN easily through ThrottleStop FIVR menu, no need to change Core voltage to static, the feature is right below the Core voltage thing if I remember correctly.

 

PowerCut might work correctly on your CPU but it looks like you did not enable it yet. The included ReadMe file has all the details. To be honest though, why bother? If you are running a 44 multiplier on a 4710HQ, you really do not need PowerCut. Those guys at Intel are probably scratching their heads right now. Sales of over priced unlocked K CPUs might be going down. Good work!

http://www.cpu-world.com/CPUs/Core_i5/Intel-Core i5-5200U Mobile processor.html

When 2 cores are active, the maximum multiplier is 25. The 27 multiplier is only available when 1 core is active. In ThrottleStop, 1 Core Active should be set to 27 and 2 Cores Active should be set to 25. Unlike XTU, I left these unlocked just in case someone found a way to go beyond the default values. hdneo probably agrees that was a good idea.

For a 5200U, you would need to flash a modified bios with an early microcode for any hope to get beyond Intel's limits. I am not sure if that is possible with your CPU. Your CPU is running fully loaded at its maximum designed speed. There is no need to check anything else off in ThrottleStop.

EDP in yellow or anything in yellow while fully loaded is fine. If it is red, that indicates throttling. Yellow just means that there was some previous throttling. Sometimes this happens randomly when booting up or resuming from stand by mode. Click on the headings in Limit Reasons to reset the yellow bars before you start testing.

Same as above. Here are the specs for a 4500U.

http://www.cpu-world.com/CPUs/Core_i7/Intel-Core i7-4500U Mobile processor.html

30 multiplier for 1 core active, 27 multiplier for 2 cores active. I have not seen anyone running a low power U CPU with a microcode mod.

Under Package Power Limits, the Lock box is not checked so the bios has left your CPU power limits unlocked. You can set them to whatever you want in ThrottleStop. My 3570K also shows a minimum supported value of 60 Watts but I was able to go below this value. This is the easy way to create a lower power T series CPU without having to spend extra money doing it. You can even use this software to convert your 3570K into an uber low power, sub 20 Watt, U CPU.

I included the microcode version in ThrottleStop. It is to the right of the PowerCut check box. Drag the VCCIN slider to a reasonable value, 1.75 V to 1.80 V, and then click on Apply. You should see the VCCIN value change in the monitoring table. You do not need to use a Static CPU voltage. Only the VCCIN needs to be a fixed value.

CPUID 0x40661

CPU-Z shows that the 4980HQ is Code Name Crystal Well. PowerCut works great on my 4700MQ which is listed as Haswell. I have to assume that Intel fixed this bug when they introduced Crystal Well. That really is too bad.

Thanks everyone for the feedback so far. I always thought that the low power U CPUs could really benefit from this.

Edit - One thing I forgot to ask. Did you enable PowerCut while the CPU was idle? That is an important step.

 

Hi!

I need some help.. I can't stop my cpu clockspeed from dropping during light workload. Eg. gaming.
The problem is described here,
**Official Clevo P37xSM-A/Sager NP9377 owner's lounge**
if someone could take a look.

Thanks!

 

I use i7-4770HQ. Same Code Name, same Microcode.
I can't enable PowerCut.
