The ThrottleStop Guide

I've already done that a few times. It helped a bit for general problems related to the icon but not with the specific bug I mentionned. It's not a big deal anyway.

Acknowledgment is the least I can do

 

Dear unclewebb,

Thank you so much, once again, for this wonderful app !

I have a question related to Speed Shift - EPP on Skylake core i5.
I thought that ticking TPL -> Miscellaneous -> Speed Shift + Enable Speed Shift when ThrottleStop starts was enough but, today, I also ticked on the main screen -> Settings -> Speed Shift - EPP and I think my cpu behavior has changed and is snappier (but may be due to the FIVR -> Cache ratio minimum value that I restored to stock).

Was it enabled before today or was it required to tick the option on the main screen also ?

Thanks a lot and have a great day !

 

@duttyend - If you have enabled Speed Shift and SST is showing in green on the main screen, you have to also check the SST - EPP box and set that appropriately. If you do not check this box, Speed Shift will still be enabled but the CPU will not know if you want maximum performance, EPP = 0, or typical performance EPP = 128, or run like a dog tied to a tree performance with EPP = 255. Best to specifically set this value so the CPU does exactly what you want it to do. The default seems to be 128 so you probably have not been tied to a tree. The present EPP value is always reported in the monitoring panel in the upper right corner of the FIVR window.

@Tomatot - Just curious, have you been using any scripts to kill ThrottleStop.exe and then restart it? These scripts can lead to ghost icons in the system tray that disappear as soon as you mouse over them. Usually after I do a clear icon cache, I don't have any icon related issues. I am hoping that the next version cures some of ThrottleStop's random issues.

 

Thank you so much for those clear explanations !

Regarding FIVR -> Cache ratio, does customizing the min. or max. value do any good to battery life ?

 

Nope, I've just been using the task scheduler to start ThrottleStop at boot. I'm not a developer at all but I'd say there's a bug related to the transition AC => unplugged, which makes ThrottleStop crash. Btw, I'm just remembering now, but the last time it happenned I checked the task manager and ThrottleStop wasn't listed anymore. So the bug is more related to the app itself than the icon imo. That's how I see it:

1) Unplugging the computer sometimes makes the app crash

2) Since the icon is a bit buggy in term of cache and stuff, it stays there until you mouse over: at this moment, the windows system "realizes" the app is not running anymore so it deletes the icon.

Does that make any sense?

Btw, not sure if it's normal or not, but clicking on the red cross just minimizes the app in the icon tray (that's a normal behavior since that's what I've asked for in the settings), however, if I press the key "escape", it closes the program. It's not a problem at all but it took me some time to understand the difference so I wanted to make sure.

 

MS is not targeting TS! The latest Insider build 16288 doesn't require the use of Open Hardware Monitor to run the program

 

@unclewebb It seems it was a temporary 'block' after all. Enthusiasts...tough cookie for M$'s Win10...

 

I'm assuming there's no way to undervolt just the top/turbo multiplier?

I've got a KBL 7200u that does [email protected] stock and can take at least a 100mv undervolt off the top. It's the difference between full load @90'c and throttling @99'c. However, the lower multipliers can't handle the offset.

Perhaps the only solution is to manually switch performance profiles when gaming and use one that employs static voltage instead of adaptive?


edit: Separate AC and battery profiles should do. Testing now to see if SST EPP 0 would allow for undervolting stability.

edit2: Seems throttlestop is crashing often when unplugging the power. Not sure if it's because of undervolt instability (e.g. epp goes to 128 before undervolt is reverted) or what.

 

On some CPUs, reducing the Max Cache Ratio might reduce power consumption and extend battery life. I have not had my hands on a wide variety of recent CPUs but this is something worth checking out. The slight decrease in performance might be worth it when running on battery power.

The problem you are having might be related to the Task Scheduler itself. Check out items 10) and 11) in this guide I wrote.

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

There are some items in the Task Scheduler that are grayed out so it makes one think that they are disabled when really, some of those options are enabled. You have to deliberately clear them. Just for the record, ThrottleStop does not crash on any of my computers, ever so check the task you created and if you cannot find anything suspicious, I will look further into your TS settings that you posted.



Double check to make sure the, "Stop if the computer switches to battery power" option is not checked.

I like having the Escape key as a close option. I cannot remember if that feature is by design or not. I do know it comes in handy when I am constantly opening and closing and testing ThrottleStop. I almost always have the Minimize on Close option checked so ESC is kind of handy.

That is the best news I have heard all day.
Maybe a lot of insiders have laptops that are sluggish without the help of TS. When they asked for feedback I told Microsoft that the latest version of Windows 10 was wonderful but I would not permanently install it or recommend it to enthusiasts because of their decision to block WinRing0. Maybe they listened.

@ziddey - You have a common problem. The amount of under volt you can run reliably when fully loaded is usually greater than what you can run when idle. When lightly loaded, your CPU cores are rapidly entering and exiting various C States so it is impossible to come up with the perfect amount of voltage for every condition. There is not enough adjustment built into Intel's CPUs to cover every situation. That is probably why Intel tends to error on the high side. They tend to use too much voltage to guarantee stability.

I think I read this quote recently.

I can plug and unplug my computer until my arm gets sore and my icons do not disappear and ThrottleStop never crashes.

@j95 - 16288 FTW!!!

 

@unclewebb Can I ask you a question, can TS can setup in Task Scheduler using different drive like D instead of C?
I tried your steps, so far during startup I cannot see TS in Tray Icon but shows up as a process in Task Manager. I cleaned up Icon Cache. Any ideas?

 

I have to say I feel very bad... I think it was the issue. I fixed it so I'll let you know if your solution works. It's very possible. Sorry for wasting your time.

 

@Vasudev - If ThrottleStop is showing up in the Task Manager then check the Triggers tab in the Task Scheduler. You only want ThrottleStop to start when you log on. If you have TS starting before you log on, you will not be able to access it in the system tray. If you are still having problems, post some screenshots of how you have the Task Scheduler setup.

No problem. I always learn from other users and their experiences with ThrottleStop. I should write some code so a task is added to the Task Scheduler with a simple check box in ThrottleStop. That would make it a lot more fool proof. I am not a big fan of Microsoft's decision to make that the default option and then have it grayed out so it looks like it doesn't apply.

 

" I am not a big fan of Microsoft's decision to make that the default option and then have it grayed out so it looks like it doesn't apply."

Yeah that's really stupid, in a lot of other apps when it's grayed, what's inside doesn't matter.

 

Yep that worked. Thanks. +rep added.
Your guide needs to be updated. Creating a task when computer starts no longer works. The task works only when a user chooses "Start app when logged in". We may be seeing future windows releases using this. The option start task when PC starts used to work on Anniversary and earlier OS releases. I hope Power throttling won't conflict with TS's Intel SST and break good old app. I am relying on Phoenix's experience about RS3 and later. If its bad, I am freezing Windows Version to Creators on all my PCs until the end of its lifecycle.
Did you get any word of Power Throttling affecting TS's functionalities from Windows Insiders?

 

I will have a look at that in the next day or two. I try to wait for the official releases in case Microsoft changes their mind.

No one has said anything to me about this. It is another thing I need to look into. Thanks for the feedback. Now that the WinRing0 issue seems to be fixed, I can get back to work on TS this week.

 

Damn, I found out why my turbo ratio sometimes is only 28. I used HWiNFO to monitor the summary of processor. Normally the cpu should have turbo feature enabled (green).


When I started prime95, suddenly the turbo feature became red. Looks like bios or Windows did something to the cpu.


But why is it happening now. In the past it rarely happened, I was able to test prime95 at full turbo speed

 

Check for any BIOS update or check BIOS settings if you have disabled Turbo.

 

@kakashidinho - This is the ThrottleStop thread. Why not post some pictures of ThrottleStop? Some laptops when pushed hard will deliberately disable Turbo Boost. ThrottleStop might be able to help with this problem if it is setup correctly.

Your 7th Gen processor supports Speed Shift. Have you ever tried using ThrottleStop to enable it? I would do that, I would go back to the main screen and check the Speed Shift - EPP box and I would set that to 0 for maximum performance. Make sure it shows SST in green which confirms that Speed Shift is enabled. I would also make sure that Disable Turbo and BD PROCHOT are not checked. After that, go run a stress test and if your CPU is throttling, post a picture of ThrottleStop. Include Limit Reasons in your screenshot.

 

For an interesting primier Intel Turbo Boost Technology, please see the five-page article in the August 2017 edition of CPU magazine, "State-of-the-Art-Standards, Intel Turbo Boost Technology". It touches on multi-cores, turbo evolution, turbo limits, c-states, and the newer Turbo Boost Max 3.0.

https://www.computerpoweruser.com/a...he-art-standards-intel-turbo-boost-technology

Hardcopies were free at the local MicroCenter. I picked up several issues and enjoyed reading them. Forgot how much I like tearing through a magazine from cover to cover. I assumed this magazine was purely "sponsored advertisements" but there are plenty of products rated poorly; the Intel 7740x received a terrible review along with a brutal 2.0/5.0 rating.

 

Got a Lenovo P50 from work with a 6700 HQ. This laptop has Speed Shift enabled by default. Looks like Windows Balanced Profile uses EPP 127 instead of 128. High Performance uses EPP 0.

 

Nice, how far can it undervolt?

 

I have not tried it because it is a work laptop lol. By the way I am noticing the Limit Reason is in constant EDP Other (Yellow Color) but the actual cpu is not really throttling.

 

Just out of curiosity, I used Intel XTU and set the maximum multiplier to 28 and there wasn't anything that ThrottleStop could do about it. XTU changes the multiplier value in two locations and ThrottleStop does not have access to the Memory Mapped IO setting. When this is set to 28 (0x1C), the CPU is stuck at 28.



MAX PERF is shown in Limit Reasons which confirms that the maximum multiplier is being limited by this setting. When I first boot up, this memory location is usually set to 0xFF, which basically means that it will not interfere with the maximum multiplier.



No more MAX PERF in red. If anyone has a laptop or tablet that is showing MAX PERF, adjusting this memory location (FED15990) might be a way to fix it so the CPU can truly achieve maximum performance. The memory location beside it, (FED15994) controls the maximum Intel GPU multiplier.

 

Very weird, the moment I put load on the cpu EDP Other gets cleared. The moment the CPU goes idle, EDP Other shows up.

 

Thanks for that. I just checked mine, it showed 0xFF. Any idea to find a firmware based hard limit imposed by OEM on a specific register or memory address?
I read through some of the errata documented in skylake platform, for BGA intel showed a bug in sleep states like c6/c10 wherein the PC refuses to bootup after entering that state, for the fix they said it can patched through a BIOS update. How is this possible? Why can't Intel fix those at the factory or by supplying microcode update directly to end users using some kind of update mechanism.

 

Intel does not publicly document what Other in EDP Other could possibly stand for. The Limit Reasons data is more useful when you have a load on your CPU and are trying to find out why it is throttling. Idle Limit Reasons data or yellow boxes in Limit Reasons just after booting up or resuming from stand by are not that important.

Probably not. These are secrets that most companies have no reason to share.

Intel prefers to do microcode updates via the bios. This way it doesn't matter what operating system you are running, the errata will be taken care of before any version of Windows or Linux starts. The long list of known flaws in every Intel CPU ever released is a mystery to most consumers. I always wonder what the unknown flaws are. Some of these bugs get patched while most seem to be ignored. Anyone interested in learning more about errata can download a Spec Update document from Intel. Here is one that covers some of the bugs in a 4th Gen Desktop CPU.

https://www.intel.com/content/dam/w...-core-family-desktop-specification-update.pdf

 

The Other EDP yellow box on idle is undeletable. I cannot clear it lol when on idle because it appears right away. The moment I put load on the CPU with TS Bench, EDP Other is clearable and stays off until benchmark ends.

 

Has anyone played around with the new 8th Gen quadcore cpu's? I wonder if TS supports these CPU's. I've got a Dell Inspiron 7000 on the way with an i7 8550u in it. I'll be firing up throttlestop to see if it works, if not i'll have to donate some more money to get support =)

 

The Core i7-8550U has a very similar CPUID to the previous generation so ThrottleStop 8.48 should recognize it and work correctly. You can save your money for the 9th Generation.

Post some TS pics when you get your new toy so I can make sure everything is OK.

 

So just wanted to say unclewebb you rock, I wanted to send a donation your way, but I see your PayPal link is gone.

I was having an issue after a x99m BIOS flash, and my 5820k was stuck at a 2.7GHz throttle limit due to PPL1, XTU didn't do s*** - but good lord in heaven did ThrottleStop save me!

Thanks again. 150W max set, and no throttling here!!

 

@jaug1337 - Always love hearing a TS success story, especially on a desktop board. A lot of desktop enthusiasts have never heard about TS or think it is only for laptops. I think TS is ready for Intel's new 6 core 8700K. Bring it on!

 

how to increase the limit current???

 

I think that's under PP0 power limit and current limit in the bottom left of the TS TPL window? Not sure if that applies to your system.

On later machines that should be controlled by "ICCMax" (CPU Current Amps limit)

 

how to increase the limit current???

 

I didn't say power limit. I said current limit. It's in the same area.
That's under primary plane" or "pp0"
You need to try it and see if it works. Set it to 300 for both.
You may also have to change PL1 and PL2 to 300 if it won't let you.

 

how to do it using ThottleStop?

 

Already answered that.

 

how to using ThottleStop for change PL1 and PL2 to 300?

 

how to using ThottleStop for change PL1 and PL2 to 300?

 

There is the Current Limit and the PL1 and PL2 power limits are above that. Package Power Long and Package Power Short. This laptop shows Lock which means these settings are locked by the bios and cannot be changed.

 

I have this current limit value PP0 current limit 55
and I will not be able to change it???

my laptop is not working properly
at low temperature the CPU is not running at full capacity
this is not correct


this parameter is the CPU or the motherboard? if I change my processor to i7 4700MQ - I have it all working normally??? or not?

 

Does ThrottleStop show Lock? This limit is set by the motherboard in the bios. If this does not show Lock then you can increase it.

That depends on the motherboard. It is impossible to say what will work normally unless you or someone else with the same motherboard installs a 4700MQ and tries it.

 

Post a screenshot picture of your Turbo Power Limits window then we can see what you can change.

 

I'm still new using TS.
how to undervolt using TS?
I changed from 1.050 V to higher volt (1.25V), it work.
But if I changed from 1.050 V to lower volt, it stay 1.050 V.
I looked tutorial in youtube, I must click FIVR. But I cant find any word in TS

Here my picture TS interface...
Thanks in advance

 

Thanks for the pic. With your CPU you have to use the Windows High Performance power profile with the Minimum and Maximum processor state set to 100%. If you do not do this, Windows power management will interfere with your ThrottleStop voltage request settings and your computer will crash.

Before checking the Set Multiplier option in ThrottleStop, adjust the maximum multiplier appropriately and adjust the voltage appropriately. If you want a low multiplier when the CPU is idle, combine this with the Power Saver option in ThrottleStop.

Are you using your X9100 on an older motherboard that uses the lower front side bus speed? (200 MHz vs 266 MHz)

If you need to adjust the voltage for each individual multiplier, try using RMClock.

The older Core 2 Duo processors do not use FIVR so under volting these older processors is different compared to the tutorial you were watching on YouTube.

 

Am I missing something or there is no way to just keep the notification area icon?
Also, I'm not doing much of an undervolt (-60 on core/cache on 7700HQ), but Chrome browsing temps have gone from 42-48 to 36-39C, this is magic. I suppose Intel could do a Coffee Lake release by just adjusting voltages with some of the instruments they have

 

Maybe. You did not post any pictures of ThrottleStop so I cannot tell how you have TS setup. On the main screen, make sure that Task Bar is not checked. If you are still having problems, read the last few paragraphs of the included ReadMe file and try doing that. The solution for your problem is usually something simple.

 

More likely Taskbar option is checked in TS main window. I needed to clean notification area icon cleanup twice or thrice and a reboot to get it fixed.

 

Hello everyone,

I have been using throttlestop since release, but I have run into a very weird issue with my new laptop.

Undervolting with throttlestop is working, but for whatever reason, the "set multiplier" function does not work, so I am unable to clock down my CPU.

My laptop has a i-7700 HQ. This issue is bothering me because I have used throttlestop many many times before on different laptops and never ran into these issues before.

In addition, I have tried playing around with the power plans, and even if I set my max cpu to 60%, my clocks still go up to the maximum.

The reason why I am trying to clock down my CPU is that it is always running at maximum frequency of 3.5ghz even when idle. the only thing that has worked was disable turbo, which limits my frequency to 2.8ghz, but I was looking to dropping much more than that and make as a profile while doing web browsing to save power and lower heat.

Thanks in advance!

 

The 7700HQ does not come with an unlocked multiplier, but you can set the multiplier down. The 'set mulitplier' switch doesn't work on newer processors. You can go in the FIVR, then click overclock and set the multipliers lower (But not higher) than default, or uncheck overclock, lower the multipliers, then check overclock again and apply. That should work.

You can also just enable speed shift, then set the min and max ratio there in the TPL window under speed shift. You can set a speed lower than the maximum that way, like if you wanted x24, set min and max speed shift ratio to 24. That should lock the clocks at 2400.
