The ThrottleStop Guide

TS will still flash warning if your CPU cross current limit or TDP limits or other Limit as well.

 

Yes, but on my limit reasons only appear BDProchot... i disable that feature in Bios but i still see the yellow signal on TS.

 

@unclewebb, I do own an interesting device " GPD WIN 2". A gamepad with an Intel Core m3-7y30 with a fully unlocked bios. Because I do have full control over the bios and because the device heatsink was made that way, I can raise the TDP to around 15W (instead of 7W) without thermal throttling.

But, I'm facing an issue where on heavy CPU load, the Intel HD 615 frequency will stick to 450Mhz instead of 850Mhz. When both cores are being heavly used (gaming emulation) the GPU frequency won't go any higher than 450Mhz even if none of the following things are throttling : Power (TDP), Current (Amp), Thermal.

I already tried to disable Turbo Boost, Speed Shift, Speed Step and increase GPU frequency but none of those gave me higher GPU frequency during workload. The only way for the GPU to raise to 850Mhz is when (even if both core are working) the workload is not " too intense".

So I'm wondering what kind of settings/trigger on the BIOS I should look for to make sure I can have at the same time both core at 2.4Ghz and GPU at 850Mhz.

ThrottleStop Intel Power Balance was set to 31/0 (GPU/CPU) and Graphics Turbo IMON Current is set to 31 and Gfx Low Power Mode is set to Disable on the BIOS.

Any help here would be appreciated. Regards, Ben

 

What exactly is Graphics Turbo IMON Current?
And how did you get a GPD Win2 if it isn't released yet?

 

Well looking at its value in the bios... 31, I thought it was related to power balance. I was able to order one of the 8 GPD WIN 2 prototypes.

 

Nice. I want one of those. Would make a nice Steam indie/RPG/arcade MAME emulator portable box with built in joysticks, without having to carry a 10 pound DTR laptop around...
and hmm...good notice on that "31"...same value in throttlestop under power balance...but not going to experiment with that value

 

omg, i thought i was the only person who noticed that.

does anyone know how the new "battery/power slider" in Win10 FCU maps to actual EPP values?

On battery mode, the slider has 4 unique points. On A/C, it has 3.

 

That's the reason I didn't upgrade to FCU but stayed on CU.
If you noticed increased stuttering on Best battery life mode then I suppose EPP value will be more likely set to 255. I actually prefer value of 200 on battery mode. If you don't see stuttering, then I suppose the value is set automatically between 200-255.

 

Does anyone knows how to permanently disable the sensors (temperature, etc..) from ThrottleStop?

 

Click Stop Monitoring or Stop Data in TS Main Window.

 

And for removing Battery monitoring you will need to uncheck "use default profiles" as well as uncheck "battery monitoring" in Options tab. You can as well remove Graphics monitoring in same Options tab. But why will you do this? TS sensors data monitoring doesn't kill your cpu power. Not measureable.

 

I have had zero hands on experience running ThrottleStop on a Core m3 processor. Without new hardware, I cannot improve ThrottleStop.

Why not do some testing? Do not check or set the Speed Shift EPP value on the main screen of ThrottleStop. Open up the FIVR window and have a look at the monitoring panel at the top right. That data is being refreshed every second. It shows the Energy Performance Preference (EPP) value that the CPU is using in that window. Switch between different Windows power profiles while watching that window for changes in the EPP value. Post your results.

The next version of ThrottleStop will remember if you previously disabled sensor monitoring. Monitoring does not actually stop but the update interval when Stop Data is used is reduced to once every 60 seconds. Even with full monitoring, ThrottleStop is an insignificant load on any modern CPU.

Yellow means that a BD PROCHOT message to the CPU has previously occurred. It is possible that this happens before the bios has a chance to turn BD PROCHOT off or perhaps this feature in the bios is not working correctly. In ThrottleStop, click on the headings in Limit Reasons (CORE, GPU, RING) to clear this data from the CPU. After that, the yellow BD PROCHOT should be gone. Now go use your computer and see if BD PROCHOT turns yellow again in ThrottleStop. I do not own a computer with BD PROCHOT issues so I am not 100% certain what Limit Reasons reports when BD PROCHOT has been disabled. I would just run a Log File. When BD PROCHOT is active, you will see the CPU locked at the minimum multiplier which is usually 8 or usually less for the U CPUs. If the multiplier in the Log File shows 8.00, 8.00, 8.00; that might be a sign that BD PROCHOT is still active. In the Options window you can also check off, "Add Limit Reasons to Log File" and any BD PROCHOT messages should be recorded in the log file. Also remember that after you start ThrottleStop, it will be in control of BD PROCHOT so anything that you set in the bios for BD PROCHOT will be ignored.

 

@unclewebb
The EC can enforce 800 mhz CPU throttling without even flagging BD prochot, somehow.

 

so no matter what in speed shift the number is 128 even when im playing games like overwatch or gta 5, im in the latest version of windows and have a 7820hk cpu

 

Can you explain this some more? What number is 128? The number on the main ThrottleStop window or the Speed Shift number in the FIVR window? Did you check and set the EPP value on the main screen of ThrottleStop? How about post some pictures? Are you trying to say that ThrottleStop is working or not working or Windows is working or not working or ...........

 

dont know if its throttlestop or the newest windows version but those are my settings

 

On the main ThrottleStop screen you have Speed Shift - EPP checked and this is set to 128. You can change that 128 number. Just click on it and edit it. 0 is used for maximum performance and 255 is for tied to a tree sluggish performance. 80 is a good compromise, similar to the Windows Balanced profile. After you make a change, click on the FIVR button and have a look in there in the monitoring panel at the top right. Does the EPP value in there change? Is it the same as the value you set on the main screen of ThrottleStop. It is possible that the latest version of Windows 10 might change the EPP value so watch for that in the FIVR screen.

To take a screen snapshot of only ThrottleStop, hold down the ALT key and then push the PRINT SCREEN key on your keyboard if your keyboard has one. After that you can Paste the image into any paint program or paste it directly into imgur.com.

 

ah thanks for that as for epp is 128 the best number for battery mode?

 

The best EPP number varies depending on the CPU and what apps you are running. A value of 128 is good for battery mode but it can also limit maximum performance. That is why I like 80 better than 128. Many people running on battery power do not mind a little less performance so they are happy with 128. I am mostly plugged in so 0 is the best number for me.

@THE-HL - So what is the verdict? Is ThrottleStop working OK? Does it let you set and maintain an EPP value without Windows changing it?

 

Yea it works alrite, looking forward for the next release

 

Fix your cooling if you want-prefer change from 128 to lower value. You already cook your chips Fix your overheating problems regardlees what settings you want to use in TS. Your Cpu wan't be working long time with this temp.

 

800MHz bug is back.

 

yea i tried repasting it but 3 heatsink screws got stripped so i cant take it out and repaste it anymore and dell told me they dont have the tools necessary to take the screws out, so yea

 

If you can't fix it yourself... Try a local Computer repair shop. If you still want run it as it is, don't run max performance. Follow @unclewebb's guide regarding how to put Speed Shift - EPP settings for less Performance. Good luck, sir

 

@unclewebb I have throttlestop set to start with windows, however it starts the service but doesn't put the icon in the task tray so if I want to open throttle stop to change settings, I have to stop the task and then re-start the program. Any way to fix this?

 

Maybe. Did you follow the guide on page 514?

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

Step 3) in the guide might be the problem.

It sounds like you have ThrottleStop starting up before you log on. Fix that and see what happens.

Edit - I just remembered. I finally fixed up the original guide in the second post of this thread. Lots of info there to point you in the right direction.

Hey friends!
I'm sorry if this is a stupid question (or if it's already answered in this matter). Today was the first time TS shows a warning message (CPU not supported) since I've purchased my MSI GE63VR. It's a 7700HQ, what's the cause for that?
Also thanks for this magnificent piece of software, unclewebb!

EDIT: Issue is fixed immediately after I plugged my laptop in. It appears TS just won't run when the laptop is on power saving profiles!

 

@unclewebb

Greetings!! How are you?

I'm hoping you can help me because I'm running out of ideas.

Im having EDP Current in CPU, GPU and RING when playing games, so when gpu is under load (cpu +gpu)

I managed to unlock lots of bios setting, that I can customize now.
Already tried changing processor current limit and the turbo boost power limits

Any ideias?!

Thank you

Currently your processor can work safely up to 100c according to Intel but I think your laptop OEM specified to set it only up to 97c according to your screen shot so... first of all.

Fix your thermal issues because you're already touching the limit of PROCHOT that the OEM specified.
Did you try to undervolt & see if it helps your current thermal issues?

In general.. get your thermal fixed first and then tweak your CPU settings to whatever you need

 

A quick question: Can I bump up the Turbo TDP/TDC by say doubling it from stock value and ensure throttling is held back? Basically, I want all my benches to run whilst the CPU is at its max core clocks on all cores

 

Can you post a screenshot of the ThrottleStop TPL window? Is PP0 Current Limit adjustable? Some manufacturers set some very low limits that can trigger EDP throttling. ThrottleStop might not have access to these limits. I agree with @THEBOSS619 and you should start by trying to improve your laptop cooling system. It is not the main cause of this problem but hitting the PROCHOT temperature is not helping things out.

@NeonSun - What CPU do you have? Sounds like a 1st Gen Core i that used the TDP/TDC settings. Post some screenshots. If TDP and TDC are adjustable then adjust them higher. Watch the CPU multiplier (speed) while benching to make sure that your CPU is running at its maximum speed. I recently picked up an unlocked W3680 to play with. Bumping the TDP up from 130 to 180 helped it maintain full speed when it was running Cinebench at 4133 MHz. I will do some testing and post some pictures later on. ThrottleStop and the 1st Gen Core i were good friends way back then.

 

@unclewebb @THEBOSS619

Thank you guys for the replies.

I have a cooling pad, and changed thermal paste and dusted off the interior a few weeks a go.
Sometimes the temps spike up, but not often. High demanding games temp is between 70-80C. Normal games 60-75C

 

Quick question as I couldn't find it anywhere: Does throttlestop always work in the background or do I actually need to open it to work ?

Thanks

 

It depends on how you have ThrottleStop setup. There are a variety of ways to start ThrottleStop so it is possible to have it running on your system without there being an icon for it in the Notification Area / System tray at the bottom right of your screen. Open up the Task Manager. Click on the Details tab. If you see ThrottleStop.exe in this list then it is running. If you do not see ThrottleStop.exe in this list then it is not running on your computer. That is the easiest way to see if it is working or not.

When you exit ThrottleStop, it generally does not set your CPU back to any sort of default settings. If it is not showing up in the Task Manger, it is still possible that it is influencing your CPU. Most under volting and over clocking settings will be persistent after you exit ThrottleStop. For default values, it is up to the user to set up a profile with default values and switch to this profile before exiting ThrottleStop so it can return the CPU to these values.

 

So in the end it may always be sneaking in the background Best thing to do then is to set a default profile, press save and exit!

Thanks

 

Question for the group.

When Throttle Stop is enabled with any type of undervolt. HWInfo 64 reports CPU L2 Cache Error. When I reboot an do not use throttle stop at all. No errors. Prior to Nov. I had zero WHEA Errors and no issues with my undervolt.

This seems software related. I've checked all my updates and drivers. Reflashed the bios. I am not sure what else to do.

Thanks for the help.

 

Greetings all & Unclewebb,

Long-time RealTemp user here (on my trusted i7-920 desktop rig; still going strong after 9 years!) and recent ThrottleStop user on my XPS 13.
I use ThrottleStop to enable SpeedShift on my XPS 13. Like some others here, I've noticed that sometimes after standby/suspend, it "forgets" SpeedShift and it's actually turned off. Has anyone discovered any solutions for this, other than manually going into "TPL" and flicking SpeedShift back on?

Unclewebb, could this be something potentially automated in a future TS version?

 

Reset BIOS to default using Dell diagnostics usb and try again.

You can check mark Enable Speedshift when TS is turned ON.
Provided you have already set EPP value in TS main window SST shifts between different P states autonomously. Disable Speedstep and C1E in TS only(Don't touch BIOS variables at all, doing so might lock out the CPU freq. to 800MHz) to get full power of HWP aka Speedshift feature.

 

@unclewebb

The main reason of BD-Prochot is the temperature or also can be the excess of voltage?

 

BD Prochot is -something- signalling the Embedded Controller, or the EC itself, that you've exceeded some sort of limit somewhere. It can be temperature, current, AC, Battery, PCH, basically, anything outside of the normal "Package Power Limit", "Cpu voltage limit", "VR Current Limit", PL3/PL4, SVID, etc, and always causes an 800 mhz lock on the CPU.
It's possible for this 800 mhz lock to be turned on by the Embedded Controller, even WITHOUT BD Prochot being flagged. This is very rare and is usually caused by exceeding some sort of AC limit.

 

I dont know if you saw my posts but i found 2 more people with the same issue, one in GT72VR-7RE(same as me) and another on MSI GT72VR 6RE

https://forum-en.msi.com/index.php?topic=299155.0

I need find a way to check what is causing this issue.

 

I am having a wierd issue with my Xeon E5-2690 v3. For some reason i am getting Current limit throttling even under virtually no load (1-5% cpu), and the Package TDP never goes beyond 75W during stresstest, even if its capable of 135W. I really need some help figuring this out. My motherboard is a Asrock X99E-ITX/ac with the latest BIOS.

 

Change VR (CPU Current Limit) / ICCMax to 100-200 amps.

 

Could you post pict of your TS main windows, FIVR, TPL settings. Have you tried follow How to Lower Temperatures, Stop Throttling guide ?

 

I am very disappointed that my i5 5200u doesn't undervolt well. I used to see here that people were able to undervolt up to -150mv but it seems sweetspot for this particular CPU is -50mv for me. I've tried -75mv and seemed okay for a long period of time but hanged while playing FIFA 18 and I had to do hard reset. How can I know when this would happen so that I might configure profiles? Any sign besides of system hanging?

 

Now i only use TS to monitoring the Bd-Prochot, to edit values i use Bios....
Im testing other things but if i not wrong when the Bd-Prochot appears my GPU and CPU never go high of 70ºC...im thinking now if not is something related with current or voltage.

 

Bd-Prochot never appears if you run pure Cpu benchmark - stress tests (only with load on cpu and gpu)? I would put max values in bios and play with different Throttlestop settings (speed shift - EPP - voltage etc) as in mentioned guide. But don't run XTU when you use TS. You could as well test with XTU. But one software each time.

 

Hi Vasudev. That's not the issue. SpeedShift is enabled fine via my TS, and setting EPP # works fine also. Also, TS is always running in the background (via Task Scheduler, it automatically runs on User Logon and I never close it)

The issue is that, upon waking from "sleep/standby", when I open TS and check it, it appears that something in Win10 FCU has disabled SpeedShift and I need to manually re-enable it. If I forget to manually re-enable SpeedShift, then my post-wakeup computing session is done without SpeedShift.

That's why I was looking for a way to automatically re-enable SpeedShift after waking up from sleep/standby (possibly "modern standby"). Since TS is always running (I never close it), the fact that TS can enable SpeedShift on startup will not help in this instance.

 

Well, i already have speed shift activated in my bios. I need know what values i need check to avoid Bd-Prochot.

 

Looks like you are using hybrid shutdown aka Fast start. Disable that using powercfg -h off and see if it fixes the issue
