Throttlestop not working right.

Hi all,

I have an Alienware 17 R3 with the 6700HQ, and i've been using throttlestop for the last month and enjoying my awesome -12c temp drops, but today i noticed something weird, in my cpu heavy games (BF1, Planetside 2, guild wars 2) i noticed unusually lower fps than i recall, so i ran HWinfo 64 and HWmonitor to see if something, and someone was indeed.

On all 4 core my cpu should run at 3.1ghz, and indeed it does when i first start up my laptop and test these games, but as soon as i run throttlestop (even with no profiles set up at all) my clocks drop to 2.7ghz, this has been consistent whether i run a -125mv, -100mv, or - 50mv offset Undervolt or no undervolt at all, it happens as soon as the throttlestop application runs.

what's odd is that when i benchmark using any cpu stress test, it reaches the proper clocks with no crashing, even with - 125mv offset

What am i missing here?

 

Can you post some pictures of how you have ThrottleStop setup? The main window, the FIVR window and the TPL window would help out. There is a thread dedicated to ThrottleStop so it would be a lot better if you posted your ThrottleStop specific questions over there. The link is in my signature.

 

will do

 

This is throttlestop as stock, and simply running it will cause the aforementioned problems.
For my UV i simply change CPU core and CPU cache voltage offset by -125mv

 

You could try to check the box <disable and lock PL 3> in TPL window and uncheck BD Prochot in the main TS window.

 

don't really need to anymore tbh, i gave xtu a try and it worked well, only had to fiddle with the core and cache offsets.

but i'll try that anyway so we can see where the problem is coming from

 

TS is simply better than XTU and very user friendly.

 

I see you have Speed Shift enabled. The default EPP setting of 128 reduces performance. For maximum performance try setting EPP to 0. That is probably one reason why your clocks are dropping when you are using ThrottleStop. TS 8.40 lets you use different EPP values for each profile so it is easy to shift from maximum performance to a more balanced like setting.

I would also disable BD PROCHOT, C1E and the Clamp option in the TPL window. No need for any of that.

If your screenshot of ThrottleStop was posted when your CPU was idle then you need to spend some time cleaning up the excessive number of background processes running on your system. An idle CPU should be spending about this much time in the C0 state working on background processes.

 

@unclewebb: What does clamp option and PP0 limit do, I have it enabled by default? Also SST value to 100 for game profile, 186 and disabled turbo for internet profile and lastly for battery profile SST is set 255 and UV'ed to 170mV for max battery life. One more thing I noticed is that my core temp and PCH temp are having a difference of 5C as opposed to your screenshot why is that?

 

i had just fired up the laptop, maybe it was just loading up background stuff still?

i don't have many things running in the background, only essential stuff that i use.

 

@Vasudev - Clamp option allows the CPU to throttle below the default multiplier. With Clamp enabled and a low power limit enabled, the CPU can drop all the way down to 800 MHz when loaded. I hate a slow, throttling CPU so I never check that one. The Temp reported in ThrottleStop at the lower right is not the PCH temperature. ThrottleStop reports the CPU package temperature. There are multiple temperature sensors throughout the CPU package including the individual core temperature sensors. The package temperature samples all of the sensors on the CPU package and reports the highest temperature. These sensors are not 100% accurate. Perhaps one of the sensors is out by a few degrees. They are only accurate to 5°C and that is at the calibration point. There is probably more error than this when idle so I would not worry about a small difference.

@abdullah_mag - Keep an eye on the C0% after you boot up. On a laptop with a fast hard drive, the CPU should settle down soon after boot up. If it is grinding along at an average C0 of 10% then find out what is causing the problem. Windows 10 and some antivirus programs are terrible if you let them. Did you try playing around with Speed Shift or did you decide to use XTU instead? XTU uses more resources compared to ThrottleStop and will give you less performance compared to ThrottleStop when it is properly setup.

 

i've been busy these few days, i will check and test everything on Sunday or Monday probably.

but for now i'm letting XTU handle the UV

edit: this is also the first time i've ever heard of speed shift (i am ashamed).
it seems like i need to do a bit more homework than just lowering the core and cache voltage offsets, especially in throttlestop.

 

I think Speed Shift is a great way to control the modern CPUs but many laptop manufacturers are not even bothering to enable Speed Shift. ThrottleStop makes it easy to switch profiles and use different Speed Shift settings. Worth learning more about this when you have the time.

 

from what i could gather so far all i need is a windows 10 and skylake or above laptop that is running build 10xxx or something and it should have speed shift enabled, or alternatively use TS 8.30 and check the box in TPL.

Is there something else to do?

 

I uninstalled XTU and reset my voltages today, reran TS 8.3 and set my EPP to 0 as suggested and fired up one of my games, and it seems to be using the multipliers properly now.
Gonna do some more testing to confirm that.

If you would, could you please explain to me what C1E does??

edit: this is my C0 on idle with only throttlestop running

 

@unclewebb: Are Clamp and TDP level control options mutually exclusive option 'cause I've enabled cTDP. With clamp turned off, my cpu barely touched 70C under heavy gaming thanks for the tip.

 

Use TS 8.4 instead. Yeah @unclewebb what does c1e demotion and undemotion means?
