cpu capped at 0.79 ghz

[vetris]

hey fellas, title says it all. i7 8750h, acer nitro 5 laptop, system is basically at 0.79 ghz at all times when running even slightly intensive games. i tried disabling bd prochot, nada. i also tried re enabling it out of desperation... nada. any ideas? kinda desperate here. the cpu is supposed to get up to abt 3.80 ghz but id be totally fine if it even ran at 1.5 - 2 ghz. not whatever that 0.79 stuff is.

What are your power settings set to? (windows settings->System->Power & sleep->Aditional power settings)

How are the temps when under load?

 

Not same PC model, but on my moms laptop I noticed when it was plugged in It downclocked the CPU to ~1.5 GHz. While when on battery it ran normally.

Turned out the 45w power brick Lenovo had provided was too small. I got her a 65w one and everything was fine.

It might be something similar

Check your temps, and your power plan.

This is a common problem on Intel systems. Check your event viewer for this error: 

 

A couple reboots can generally fix it, but if it keeps occurring then update your BIOS, Chipset, and other drivers from the manufacturer.

Is the battery in good condition? Some laptops will cripple themselves if the battery is faulty.

Show some screenshots of ThrottleStop so I can see how you have the program setup. When your CPU is stuck at its minimum speed, open the Limit Reasons window to find out the reason for throttling. Some computers are setting the turbo power limits to near zero which causes this throttling problem. Turn on the Log File option so you have a record of your CPU performance. The log will also include reasons for throttling. Attach this info and some screenshots to your next post. Include the main window, the FIVR and TPL windows and the Limit Reasons window.  

 

What shape is your battery in? Can it hold a charge for an hour? An almost dead battery can be the trigger for some types of throttling even when you are plugged in.

1. high performance

2. pretty hot honestly... literally going up to 95 max.

4. i mean, its not dead for sure. it works fine. i keep my laptop plugged in most of the time tho

for the battery, i usually keep my laptop plugged in, but when it isnt, i usually get 1 hr 30 of battery when im just browsing the web and watching youtube. when im gaming, i get little to no battery, and also my games lag hard

 

im not gonna do anything right now, just waiting on some update from yall on what my next step should be. cheers

Your laptop has set the thermal throttling temperature to 95°C so when it reaches that temperature, it is going to sit there and throttle as much as necessary so it does not exceed 95°C. 

 

The next problem is VR THERMAL throttling. This means the voltage regulators are getting too hot. When was the last time you opened up your laptop and cleaned it out? Never? Have you ever replaced the thermal paste? Heatsinks get full of dust over time and this reduces their ability to cool. Reducing the turbo limits to 30 helps control the heat but it also reduces performance significantly. Why not try to fix the actual problem? Your laptop is running way too hot because of poor cooling. It is throttling for a reason. 

 

I would avoid undervolting the Intel GPU. If you have a Nvidia GPU, this is used for the heavy lifting. The Intel GPU is rarely loaded significantly so undervolting it will likely cause instability without reducing temperatures any meaningful amount. If you do feel compelled to undervolt the Intel GPU, you also need to undervolt the iGPU Unslice. These two voltages are linked and should be adjusted together. 

 

Your laptop is using BD PROCHOT throttling so I would clear that box on the main screen of ThrottleStop. Fix the cooling problems first before doing this. 

 

Where is a log file? That will show how serious these issues are.

you got me, i actually havent cleaned it.. ever, i probably really should though

also apologies, but how do i get a log file?

Put a check mark in the Log File box. It is fairly easy to find. 

 

 

The default location for the log file is your ThrottleStop / Logs folder. It is best to exit ThrottleStop first so it has a chance to finalize writing data to your log file. 

 

For maximum performance, laptops need regular maintenance. Most people ignore doing this until performance tanks. This is kind of like buying a new car and never checking or changing the oil until the engine seizes. Learning how to do some basic maintenance costs less money compared to replacing your laptop every few years.
