Thermal throttling on turbo boost, can i reduce power with TPL?

[alexfan]

Hello,

I am seeking aid of reducing power/or configuring properly on my turbo boost using ThrottleStop. Would be very appreciate for advise.

The reason is - i think i am having thermal throttling on CPU though its temp is really OK.(measured with ThrottleStop and HWinFO64)
I believe the issue is the one of the thermal sensors on embedded controller.
When i play a game that require turbo for few minutes - one of sensors becomes >=100 C and i got thermal throttling.

I tried to switch off BD PROCHOT, but that leads to PC shutdown. Also tried to disable turbo, but it does not helped.
I got constant POWER limit indicator as red(CORE POWER, GPU POWER red) Can somebody explain what exactly does it mean?

Posting my current ThrottleStop settings.

Here is what i got set up(ThrottleStop_limits_FIVR)
and TPL i think i am doing it wrong(ThrottleStop_TPL)

After i get BD PROCHOT limits and temps(ThrottleStop_limits_when_prochot)
and here is the culprit(as i think) HWI_dell_embedded_controller_thermal_sensor

My spec is:
Dell inspiron 3737
intel I7 4500U
AMD Radeon M8870HD(R9 M200X)

Thanks in advance

Some Dell laptops with 4th Gen U series CPUs were terrible. They had severe throttling problems even when they were new. They might be OK to check your email but they were never intended to be used for playing games. The 100°C temperature is coming from something that is not being properly cooled.

Have you ever cleaned out your laptop and replaced the thermal paste?

Thanks for reply.

Yeap, i recently replaced thermal paste and cleaned the radiators, it was not that bad. Also i can see that for some reason other sensors are doing OK.
And i am not getting any thermal problems till turbo boost. Fan speed is also doing as usual, some times lauder, some times not.

I was thinking if i can twitch a bit turbo to reduce that thermal sensor temp for like 5 C( as sensor was never went more than 101 C) so i can get rid of throttling that way.

Since you cannot disable BD PROCHOT, there's nothing that can be done until or unless you can figure out what sensor is reporting that 100 degrees. My guess would be the GPU.

Thanks for the lead.
i have checked the GPU temp and its not GPU(GPU_temp)

I think BD PROCHOT is working fine for me(i.e. it reacts to sensor which shows >= 100 C)
So i can't adjust TPL to reduce turbo boost on my laptop(to reduce that sensor about 5 C temp)?
