The ThrottleStop Guide

Diversion,

I had that issue last week.

Try clicking on the "CPU color" and changing the color-font. If that does not work try doing the same for the CPU MHz. If that does not work, move everything out of the tray at the bottom right of your screen and try the color-font changes again.

One of those things fixed it for me...

 

No dice.. Tried that.. What is odd is that the CPU MHZ option DOES work but the CPU Temp does not ... So strange, even deleted settings ini and still does it. I'll try just deleting the entire folder and try again.

Edit: Fresh copy does the same thing.. very strange. Seems like some kind of Windows conflict.

 

Are you running any other software that monitors temperature, clock speeds, etc (like HWiNFO64, HWMonitor, LatencyMon, etc.)? If so they might conflict with each other and ThrottleStop

 

I think he cleaned out his Icon Cache as mentioned in the included ThrottleStop ReadMe file.

http://www.digitalcitizen.life/how-clean-notification-area-icon-cache

This is an easy fix if you are ever having icon related issues.

 

I have two questions:

1. if I'm just undervolting, do I still need to press "turn on/turn off" in the menu?

2. I cannot seem to get this minimized to the system tray. if I click the minimize button it should go into the tray right? Instead, it's at the taskbar. EDIT: nevermind, got this working haha.

 

I think I found an issue on ThrottleStop speed shift settings.

I have my laptop speed shift enabled natively in BIOS. And Windows 10 "High Performance" has a default EPP value of "0", which will fix CPU frequency at the highest.

But if I start ThrottleStop, it will overwrite EPP with the value in TPL panel.

In TPL panel I have "Enable Speed Shift when ThrottleStop starts" unchecked. But the checkbox of "Speed Shift" CANNOT be unchecked (gray checked).



So I cannot make ThrottleStop NOT to overwrite Windows default EPP values.

I have to manually switch Windows power plan and back to restore to Windows default.

Any suggestion to fix it? I am using version 8.30.

Thank you.

 

The reason for this is that once Speed Shift is enabled within the processor, there is no way for any software like ThrottleStop to disable Speed Shift. If this checkbox was left unlocked, it would give users the impression that they could simply turn Speed Shift off but that is not possible. Speed Shift can only be disabled by the bios before Windows starts up.

Control of Speed Shift within ThrottleStop is an experimental feature. Based on your feedback, I will try to add an extra option to this feature so ThrottleStop will not change the EPP value unless you specifically want ThrottleStop to change EPP. Thanks for the feedback.

 

I recently picked up a venue 11 7140 tablet which has a core m 5y10 inside (broadwell).
I didn't see much information about using throttlestop to undervolt broadwell core m cpus so in case anyone wonders whether this works I'm happy to report that indeed it does work.

• CPU Core: I tested with -60mV and it seemed pretty stable (tested in furmark, and battlefield 3 - which surprisingly does run on core m, albeit with everything low and at some oddball 500x400 resolution. in an unpopulated noshar canals map just running around you can hit 60fps constantly, but with 15 people in the map that drops to 30-40fps). Cranked it to -90mV and instant blue screen.
• iGPU: -60mV seems to work okay (again in furmark & bf3). Tried -120mV and the display driver crashed and recovered. Surprisingly fault tolerant, but not stable.
• System agent: I just set it to -125mV (on desktop) and the screen started having a seizure. Didn't crash, very fault tolerant, but not stable.
• CPU Cache: Overlooked this and didn't undervolt very far but -20mV seemed stable yesterday (not going to push it now because if I crash the computer I lose all this typing lol)
• Analog IO: I tried -150mV and it froze the computer, had to reset with power button.
• Digital IO: I tried -140mV and the computer instantly turned off

My testing has been very brief but as you can see undervolting broadwell using TS is very different from doing the same thing skylake, since on skylake analog & digital IO don't do anything and the CPU Core-Cache & iGPU-System Agent are connected. On broadwell core m each of these adjustments actually does something unique.

I couldn't notice any power consumption or temperature improvements from undervolting - in my brief testing yesterday TS reported the same package/iGPU power consumption figures regardless of whether undervolts were turned on. I would be able to confirm for sure the magnitude of the change in power consumption if I had a usb power meter on hand (maybe aida64 would do it too, but not installed atm).

However, it seems these core m undervolts actually do free up the thermal/power budget for higher clockspeeds. For example when I was running furmark yesterday with no undervolt (at 400x200), sustained performance was 15-16fps (dipping to 14, never reaching 17). After applying an iGPU undervolt of -60mV, the fps magically shot up to 16, then 17 (spiking to 18, but never dipping below 16) - which is +12%. So clearly undervolting works (as if the crashing didn't already show that), but the effect is minimal at idle - and still not immediately obvious at load (during my furmark runs I had gpuz open to track power [which didn't budge at all with undervolts] and gpu clockspeeds [which randomly fluctuated between steady periods of 800MHz and random periods of 400-650MHz, but those had no correlation at all to performance nor power consumption nor whether the undervolt was enabled or not]... so, not easily measured)

 

Stop running Furmark if you value your PC... It is a total power virus.. Run something like Firestrike or Heaven benchmark if you want to do any testing..

Good morning,

I'm looking for a software that could give me my power consumption live. I have been unable to find any of that.
Does somebody know a good soft?
Thanks

 

Throttlestop has a package power display on the main screen

Many programs can show CPU (and GPU) power consumption, e.g. HWInfo, XTU, but these are usually calculated and can be unreliable

Total system power can only be measured from the wall with a power meter

 

Hey @unclewebb, here's a post to brighten your day.

I recently wrote a guide for undervolting processors using Intel XTU. Here it is:


personally, I think it's the best guide I've ever written, what do you think? =D

 

I think I would have to agree with you.

In situations where TS and XTU are both capable of adjusting the CPU voltage, it only makes sense to use the most efficient solution and that is definitely not XTU. In some benchmarks the difference in performance is significant but I rarely see any testing like that. Most people must prefer flash over function.

The latest TS feature I am working on should keep the purists like @Papusan happy. I found a way to free up some more CPU cycles. TS is very efficient as is but there is always room for improvement. If you do not need its monitoring capabilities while benching, the new Stop Monitoring button will let you turn that junk off.



I also added the ability to adjust the Speed Shift EPP value for each profile. Testing resumes this week!

 

Nice! Hopefully I'll soon be able to help you out with this =D.

 

can i get a copy of throttlestop 8.35 or 8.40 because when i alt tab out of games im having problems of throttlestop popping out

 

I know Throttlestop only works with the "High Performance" profile activated, so the following is more a question to understand more about throttling than a request for a solution (should you, however, be able to provide a solution, I would of course be more than happy to apply it!).

The thing is, having enabled Turbo Boost also on battery in the bios of my HP EliteBook 840 G1 (i5 4210u), I see exactly the same kind of behaviour whether the laptop is on AC or battery -- so long as the "High Performance" profile is active in Windows (7) power manager:



If, however, I switch to "Battery Saver" (with CPU MIN/MAX both at 100%), the processor is throttled to between FID 17 and 19 depending on processor load. Looking at the Limit Reasons window, "UTILIZATION" lights up red almost constantly:



What kind of throttling is this? Is there any way to affect whether the "Battery Saver" profile activates this kind of throttling? Ideally, I would like to be able to use that profile when on battery in order to save power on stuff like WiFi and SSD combined with Turbo Boost. Impossible?

 

Ok I think I got most of this figured out. Used ThrottleStop to undervolt and that's all at this time.

Does the undervolt stay if you exit the program?

I got it set in Task Scheduler to start when windows starts. As there any way to just have a System Tray icon and not the program tray in the main task bar?

Do I need to have it set to run on startup for undervolting?

I exited the program and re opened it and can't seem to get the Throttlestop system tray icon back?

Should I just stop using HWiNFO and use throttlestop to monitor and display temps from now on?

 

When you upload an image to imgur, use the Direct Link that they give you when sharing it.

You only need to use the High Performance profile if you are using the ThrottleStop Set Multiplier feature. Depending on what your Non Turbo Ratio is set to, this might not be important at all. On the newer Skylake CPUs, the Set Multiplier feature is useless when using Speed Shift.

On your CPU, there is no need to have the BD PROCHOT function checked.

Click on the TPL button and have a look at the top right of that window. The low power U CPUs often times use different TDP Level limits. When one of these CPUs switches to a different TDP Level, the default multiplier can change. Some CPUs have the default level and then one high TDP level and one low TDP level. The processor can switch back and forth between these levels. For most laptops, ThrottleStop will not give you any control of this. When you switch from AC to battery power, it is likely that your CPU is also changing what TDP Level it is in and this will switch the default multiplier. To see the default multiplier in action, switch Windows profiles while running a single thread of the TS Bench test. Click on Disable Turbo and see if the default multiplier is the same in both situations.

I have not had much or any experience with Utilization in the TS - Limit Reasons program. It might not be too important. Here is Intel's explanation.

Seems like a power saving feature. If the CPU has nothing too important to do, it ignores the operating system and slows down to reduce power consumption. Probably not a bad thing.

In the WIndows power profiles, you could look at all of the hidden power profile settings and compare two different profiles to try to figure out what setting is responsible for what. Doing this can be tedious but kind of interesting if you figure something out.

Open up a command window with Admin privileges and type in this command.

powercfg -qh >C:\test1.txt

The q option queries the current power profile and the h option shows the hidden values. There are piles of settings so I like to > redirect the output to a file on my C drive called test1.txt

Let me know if you uncover anything interesting. There are powercfg options that should let you change any value in your power profile. You can also unhide some of these settings so they can be more easily changed within the Power Profile GUI instead.

@Kyle English - If you want TS to minimize to the system tray, make sure that the Task Bar option on the main screen is not checked. If you have moved TS from one folder on your hard drive to somewhere else or have used multiple different versions and are having trouble with system tray icons not working correctly, read the included ReadMe file towards the end for a fix. As soon as you exit TS, it will have no further control of your CPU. The voltage settings that you set will persist until some other software changes them. This could be 2 seconds later or it could be after you do a suspend / resume cycle. Continue using HWiNFO to make sure that TS is working correctly. After that, you might not need HWiNFO anymore. HWiNFO has access to many more sensors compared to TS but if your laptop is running correctly, all of this extra info might not be necessary. Some people still like to use HWiNFO for its fan control features on some laptops.

 

Thank you unclewebb!

Will do!

OK, so I unhid all the hidden processor power management settings using regkey. I couldn't find anything to explain the UTILIZATION throttling, and none of the settings I tried in the now-expanded menu in power manager did anything to change it (I did not try everything, however).

Then I had a look at this:

And that was really interesting. First, I reset the "Power Saver" policy to default values, including, crucially, the min processor state=5%. This changed the FID to 8 when idle. However, it stayed put at 8 when running TS Bench single thread. There was no speeding up (and the bench would have taken forever to complete). So then I looked at the TPL window, and found, like you predicted, that there were two TDP levels, 1 and 2:



I guess the power saver policy changes the TDP level to 1, and thus the max FID to 8. Then I saw that there was a box to be ticked, TDP Level Control. I tried it, and put in the value 2 in the open box. Hey presto, the processor now speeds up from FID 8 to FID 27 (well, something between 25 and 27) when running TS Bench single thread and 24 (max FID for multiple cores) when running several threads.

Tl;dr: I didn't manage to change the UTILIZATION throttling as such, but I did manage to unleash the full potential of both turbo boost and power saving features in the power saver policy.

 

Hmm, I (stupidly) ticked the "Lock" box, and that seems to have broken the TDP level control. I tried deleting the TS ini and restrarting the laptop, but it's still locked. Any way of unlocking it?

 

Ok thanks for info. I got the tray icon to work no problem with that.

How do I get hwinfo to show the IA offset? It shows the voltages but not the offset.

Hwmonitor shows the offset though. It's really weird.

I should probably put a warning message on the Lock feature but most people don't read that stuff anyhow. In theory, when you completely shut down your laptop, it is supposed to disable the Lock option when it next boots up. Make sure you are not using a Windows hybrid shut down feature where your computer is not actually shutting down fully. You need to completely shut down and you might need to pull the battery if possible. You shouldn't need to go this far but every laptop is different. Simply restarting my laptop is enough to get rid of the Lock option.

Here is a trick to fully shut down a computer running Windows 8. I haven't tried this but it looks like it works.

http://www.howtogeek.com/129021/how...n-in-windows-8-without-disabling-hybrid-boot/

Not sure. Just open up the ThrottleStop FIVR window and look at the monitoring panel at the top right. It should show your voltage offsets and that window works fine so you can trust what it is telling you.

 

whenever I am in game and I alt-tab back to desktop, Throttle stop keep opening, anyway to stop this?

 

Can someone explain the benefits/disadvantages of using throttlestop vs XTU? I read a past post from unclewebb suggesting XTU if you enjoy modern looks and graphs, and throttlestop for efficiency and performance.

Is there more to this than that?

 

On my Dell 9550 (Skylake 6300HQ), Intel XTU has some "conflicts" and causes the computer to power throttle prematurely. ThrottleStop may require fewer CPU resources also.

There are also some functions on ThrottleStop that significantly improve performance on my laptop. I don't think XTU has these features and they are not officially supported by Dell so are tough to implement without ThrottleStop:

1. C1E selection
2. SpeedShift with EPP selection

Edit - I don't think you should have XTU and ThrottleStop running (or even installed?) at the same time as they conflict with each other. I like the XTU graphs but not the performance issues on my laptop.

 

Hello!

I would like to ask what could be raising PROCHOT signal - I use HWinfo64, it shows when prochot gets activated during gaming, and it usually shows that on average it remains activated (of course min=not, max=yes).
My rig is asus gl502vm and the processor usually has above 80 C (93 max) and GPU around 80 (87 max) - as these do not seem to exceed the threshold for PROCHOT what else could?
I also tried to use ThrottleStop with BD PROCHOT unchecked and the CPU and GPU temps did not go any higher than the above max...? (as the above guide suggests it's better to have it on, so normally I leave it as it is)

However, I do get sometimes black screens during playing, its rare, but when it happens it usually comes in series of several quick black screens, each for a fraction of a second. After 10-20 sec its gone.

Should I return the laptop to the seller to fix it? (bought it 2 months ago)

Thank you for time and feedback!

 

When you have a question, it makes it a lot easier for me if you post a screenshot of ThrottleStop. PROCHOT is the Intel recommended throttling temperature but Intel decided to give individual manufacturers some more options to control the heat of their laptops. They added a PROCHOT offset feature. 100°C is the typical throttling temperature for the vast majority of Intel CPUs but they allow manufacturers to use as much as a 15°C offset to that value so some laptops will start to throttle at only 85°C. I know Asus likes to use this feature. There is virtually no way to tell what manufacturers are doing stuff like this until you buy a device, bring it home, and run a program like ThrottleStop. Review sites never report this information and no other monitoring software seems to be reporting this offset value but at least ThrottleStop does. It will tell you right on the main screen what your PROCHOT temperature really is.

BD PROCHOT is completely different than PROCHOT. Disabling BD PROCHOT in ThrottleStop prevents other outside sensors on your motherboard from triggering CPU throttling. Disabling BD PROCHOT does not disable PROCHOT. The PROCHOT temperature is set by Intel and the offset to PROCHOT is set by individual manufacturers in the bios. This is usually a hidden setting so you cannot go into the bios and change the amount of offset. After you boot up into Windows, it is too late for ThrottleStop to change the offset value.

This is not a problem that any individual seller can fix. It is just poor design by the manufacturer.

 

Hello! I have an E6400 with an integrated intel gpu and Windows 10. In the past, whenever I'd try to do light gaming, I'd get insane throttling. However, i see that unclewebb has released throttlestop and apparently fixed this problem! Can anyone explain what setting i should use so i don't brick my computer but can still play games? Thanks!

 

I followed the guide here: http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/page-454#post-10247294 - to get TS working on system startup in Win 10 Pro x64. It doesn't (not there in task manager)

If I tick "log on with user" instead, it starts, but runs in the background with no tray icon and I can't bring up the GUI without first closing the .exe through task manager and restarting it.

I have double checked I've set everything exactly as per that post, what may be going wrong? The task itself isn't the problem, if I change the option and run it on demand/manually, it opens TS fine.

 

I was wondering, due to still using ThrottleStop 8.20 on all my machines (newest being Haswell), I haven't updated to 8.30 or 8.35 yet but I've noticed how voltage monitoring disappeared from the main window. I understand that voltage adjustment wasn't really in use with modern CPUs but would it be possible for voltage monitoring to return simply as a readings box? I know I could use other external software but if I can do everything with ThrottleStop, I don't really see the need to use other software if ThrottleStop contains the info I need

Edit: Are there worthwhile additions in newer versions that would warrant updating to 8.3x on a Haswell system?

 

VID voltage monitoring is not gone. It just got moved over to the right hand side where all of the other monitoring stuff is. That freed up some room so I could add some Speed Shift control features on the left side for the newer Skylake and Kaby Lake CPU owners.



One new addition is being able to shrink TS in half.



I call that, more useful info per square inch compared to any other monitoring software. Another new feature in TS 8.40 is the ability to almost completely stop the monitoring to free up some more CPU resources. That makes TS 8.40 the most efficient version yet.

How about go back and read all 500+ pages of this thread and keep track of how many people have bricked their computers by using ThrottleStop. I can recall one person doing some damage to his motherboard but he was overclocking his computer to the verge of self destruction. He did not hold ThrottleStop responsible because he knew he was pushing things a little too far. I am surprised that there have not been more problems. I guess this is a sign that many manufacturers throttling schemes truly are excessive.

I cannot remember if the E6400 had issues with Clock Modulation throttling or Chipset Clock Modulation throttling. I think it was one of those though. Put a check mark beside whatever the problem is and set it to 100.0% so your CPU can run like Intel designed it to run. Also click on the Turn On button. If you are not sure which one is causing you grief, run ThrottleStop in monitoring mode and turn on the Log File option. When you are finished gaming, if your computer has been throttling like a pig, look in the log file and find out which column shows numbers less than 100.0. The ChipM column is for chipset clock modulation.

@bennyg - Here are some screenshots of how the Task Scheduler should look.

http://www.mediafire.com/?6tnz3ccauuq3ekk

Make sure to create the new task in the Task Scheduler Library. If you have Google Chrome installed, ThrottleStop.exe should be in the same folder.



Let me know if you are still having problems and I will find my guide about 30 or so pages ago.

Edit - I like this recent guide.

Hey I'm loving the program so far, pulled off a nice -110mV on my 6500u but I was wondering if it would be possible to enable overclocking on the ULV processors/the super weak ones like mine? It's locked down in the BIOS by Dell unfortunately or I'd give it a try there, I'm not sure if that's what's restricting the program from allowing overclocking or not. If there's any files you need from me I'd be more than happy to supply them if overclocking this thing is possible, there's definitely enough thermal headroom to do it if it's possible to unlock it.

 

Sweet, that fixed it, thanks. I had it as 'for anyone' rather than for 'specific user'.

 

Recent I've got another Core M based product. The TDP control mechanism seems to be interesting.
Unlike others that use MMIO or MSR to set TDP limits, the product I got set the TDP limit to 8W in MSR and MMIO but actually runs at 7W/7.5W.
The limit reasons of throttlestop 830 shows constant EDP OTHERS (it turns red when running stress tests). Does this mean that the TDP control is actually realized through some other mechanisms like PECI? Is there a way that can help me further find out the source of limitation? Thanks

 

Thanks for the response. So it still may be the processor.. And switching for another unit seems pointless given your explanation.
I must admit I have exchanged the first unit for the current one, as in the same gaming situation, the former reached 100C regularly, with average 95C. This one is better in this respect.


PS. I must back out of these screen blinks - it happens also without load - maybe drivers...
I've hopefully included a screen with Throttlestop and hwinfo temp graphs - sorry for not including them before. I just unchecked BD PROCHOT and had TS on for some time, then off, but PROCHOT did not lit up anyway.

 

@leoncio - You have to be careful when using HWiNFO while using ThrottleStop Limit Reasons. What happens is HWiNFO constantly resets all of the Limit Reasons data that the processor is constantly collecting. When ThrottleStop tries to read this data from the processor, the data is long gone. HWiNFO has already trashed it. For best results, do not run ThrottleStop Limit Reasons if you are also running HWiNFO.

The PROCHOT box in ThrottleStop will be checked if there is ever any thermal throttling but once again, this information is stored in the processor. If you are running other monitoring software while running ThrottleStop, the PROCHOT data might be gone so ThrottleStop will not be able to report this information reliably.

Remember that BD PROCHOT and PROCHOT are two different things. Checking or clearing the BD PROCHOT box is not in any way related to what is reported for PROCHOT.

@xrender - EDP refers to electrical design point which usually lights up when you exceed the built in current limit. Have a look in ThrottleStop for the PP0 Current Limit. Sometimes you get lucky and this is left unlocked and can be bumped up a little. Most times you will not be so lucky and this will be locked without a bios mod. When the current limit is causing your throttling, the reported TDP could be less than the rated TDP because the throttling is not directly related to either the PL1 or PL2 power limits.

 

Thanks! I found pp0 current limit was 12A, no wonder why the processor is throttled at around 7w. And unfortunately it is locked

Sorry to bother you for another question: is there some mechanism to independently throttle the iGPU? One weird thing on that machine is that sometimes I found the GPU will be throttled at very low TDP. Under certain circumstances, when running a GPU-intensive task, the package is throttled at 2.5W with GPU@300MHz and CPU IDLE. If I in addition run a CPU-intensive task in parallel, the package power is brought up to full 7w. So there seems to be some clear line to separate the power distribution of the two. If I plug in the power supply, this throttling then disappears (so both can take up the whole package power if necessary). But sometimes the GPU throttling comes back again.... I tried to play with the Intel Power Balance, but does not seem to affect anything. So I am wondering if you have any clue on this. Thanks a lot!

 

@xrender - Intel's low power CPUs are designed so they can switch between different TDP Levels. If you open up the ThrottleStop - TPL window, it will show you what TDP Levels your CPU supports. Unfortunately, on most devices, ThrottleStop has little to no control over these changes. Once the CPU changes TDP Levels, it is basically the same as switching to a lower TDP rating. The default multiplier is also tied to these TDP Level changes. This means that the CPU you paid full price for can suddenly change into a CPU that performs at a fraction of its rated speed with no way for a user to control this.

Some of Intel's low power CPUs can perform quite well but in my opinion, Intel has given way too much control to individual manufacturers. There is no way to know what you are going to end up with until you take a device home and do some hands on testing. You cannot compare Intel model numbers because the exact same CPU can perform completely different depending on how each individual bios sets the various power and TDP Level registers. Buyer beware.

Edit - These TDP Level changes also effect the iGPU. There is only so much power to go around so both the CPU and GPU will throttle to stay within the lower power budget. In theory, adjusting the power balance from 0 to 31 can help direct more of the power budget to either the CPU or iGPU. I have not had my hands on any recent U CPUs for testing purposes so not sure if this still works. The difference was not huge on previous gen processors.

 

@TopTension Hey, I'm curious, what tool or widget are you using there (looks really nice)?

 

Update to that GPU throttling issue: it seems the 300MHz throttling is done through the graphics driver. I later found that I could manually disable the throttling by adjusting the driver's power saving option--and perhaps that's why the throttling is not shown in the limit reason window. There should be some bugs in the driver or the tablet firmware so that I have to do this every time to remove throttling after resuming from connected standby. Still on my way to find a way to adjust pp0 limit though..
I'm a little curious about the power distribution between CPU and iGPU. I noticed starting Sandy Bridge, Intel implemented some "knobs" so that one can adjust the power distribution between CPU and GPU:




Are these the Intel Power Balance implemented starting from throttlestop 6?

 

When the Power Balance feature was first added to ThrottleStop, it was not very useful. There is only so much you can do with a low power CPU. Some people get their hopes up thinking that with a little bit of tweaking, maybe you can turn a U CPU into a 6700K but you cannot. If you are running on the Intel GPU and you go from 10 FPS to 13 FPS, that is a 30% increase which sounds impressive but it is still unplayable. I have not heard from any users with Power Balance success stories.

The PP0 power limit covers the CPU cores and there is also a PP1 power limit for the Intel GPU. I never got around to adding PP1 adjustment to ThrottleStop. My 4700MQ does not use PP0 or PP1. I can set the PP0 power limit higher than the PL1 power limit but this does not change anything. The CPU will still throttle based on PL1. Adjusting PP0 is only useful if I want to reduce performance but who wants to do that?

 

Thanks, didn't know about HWinfo interfering with ThrottleStop...
How I grasped the idea of BD PROCHOT is that it checks for other than processor's heating issues, if it finds some overheating then it will lead to PROCHOT switching on which will lower processor's performance so that in turn the component which activated BD PROCHOT will also lower it's performance and therefore lower the temperature

PS on this previous computer I did not use HWinfo, and had ThrottleStop undervolting by 100mV the processor and its cache (under FIVR tab) but it seemed to me that it resulted in a bit lower fps count in game (might be wrong here) and someone told me that undervolting may in effect lead to errors in processing especially under high load (which is how it is in a game) - is this right?

PS2 - it seems to me that I have not uploaded the screenshot - sorry, cannot figure this out - second trial below

 

This is my own hobby project. I wanted one that displays the clocks and CPU load and some other info I am interested in at a glance and couldn't find one. There were some Windows gadgets, but they failed to report the correct clock in turbo boost. So I went and wrote me my own meter.

I considered releasing it as freeware or open source, but then I would have to put more effort into supporting all CPUs, disabling features that don't work on a particular CPU, test on various Windows versions etc. It works for me and the CPUs I have Also it still has some known minor issues, I can live with.

Don't want to hijack this thread, if you want a copy "as is" PM me.

 

back and it seems like even ThrottleStop 8.35 is giving me pop ups once in a blue moon while I am in Dota 2. side question; what is SpeedStep for in Throttlestop? I unchecked it and it seems like it's giving me better temps

 

@unclewebb I'm encountering a strange problem launching TS. It takes 2 lauches to actually open. Not a big deal, but it presents a drama if I want it to launch with Windows.
I've never had this problem before. I'm using W10 with version 8.30

 

@leoncio - The problem with BD PROCHOT is that it might have been a good idea in theory but in practice, if a sensor somewhere on the motherboard or power supply goes bad, this will force the CPU down to 800 MHz regardless of temperature or load. For the average Joe consumer or even the highly intelligent average Joes, this can be a nightmare to try and figure out. Even if you figure it out, there is no easy fix for this problem. You can start by sending your computer in for service to techs that are also unfamiliar with this issue. They might replace the motherboard with a refurb that is also defective or will soon develop the exact same problem. Much less headache to just permanently disable BD PROCHOT. I cannot remember one instance where it was legitimately needed. It is like a virus scanner that provides 999 out of a 1000 false positives. Totally useless and definitely irritating.

It is possible that under volting can cause errors that need to be corrected and this could slow things down but most of the time, your computer will crash / BSOD first. This slow down problem seems to be more common when overclocking GPUs, not CPUs. It is a good idea to check for whea errors in your Windows logs.

When using imgur, use the Direct Link that it gives you. The correct link for your picture is this.

If you want that to show up on screen in a forum then surround it in img tags.

If something is giving you better temps, it is usually because it is giving you less performance. No free rides in computing. If you do not understand what SpeedStep is doing, it is almost always best to leave it checked when using ThrottleStop.

@TBoneSan - Help is on the way. I will send you a new version that you can test out. Remember to read the ReadMe file that came with your current version (towards the end) and clean the Windows icon cache when you are having problems like this.

 

@unclewebb

You are a champion! unfortunately that didn't work though . It is actually launching but not showing anywhere until I launch it a second time still. I cleared windows icon cache..

 

I am not sure what is causing your problem @TBoneSan

What TS options are you using? Is Start Minimized checked? Is No Notification Area Icon checked? Are you using the Task Scheduler for ThrottleStop or just trying to open it up from a folder? Where is the folder located?

TS starts fine for me and shows up minimized to the system tray on the first try on every computer and every operating system I have access to. I will have to wait and see if any other users report a similar problem before I can fix it.

Edit - In the Windows 10 - System - Notifications and actions - Select which icons appear on the taskbar, it should have only a handful of things in there after you clear the icon cache and one of those things should be ThrottleStop.

 

You've been very helpful, thanks for a quick course on img posting too.
Having read your posts and others' I think I don't have to worry about my current cpu and gpu temps. I will monitor how my comp behaves with TS only. If I notice any overload/temp issues I will attempt to lower voltage.
As I gather, lowering voltage solely to lengthen the life of the processor etc. has not much sense, as these are well prepared to bear such temps and overclocking is not on my mind yet..
Windows logs - you mean the logs from ThrottleStop?

 

As a general matter, lower temperatures enable both longer life and lower failure rates for electronics. Undervolting the CPU also provides additional thermal overhead for improved CPU and GPU performance when needed. And might reduce power consumption.
