Windows 10: CPU speed dropped lower than base speed even during very high workloads

I am using a lenovo laptop with intel i7-7500U2.90Ghz - 3.5Ghz. Recently I noticed that my CPU clock has dropped to 2.70Ghz and won't go up even a little even while playing games or stressing the CPU.I have tried changing the power plan settings but to no effect. Any advice/solutions would be appreciated.

CPU speed much lower than base speed

My computer has been slow for quite a while now even while performing basic tasks such as web browsing (to the point where simply typing into a search bar can take several seconds before the computer shows me that I've typed anything) and I've finally gotten around to trying to search for a solution. I noticed that the speed listed on the performance tab of task manager is significantly lower than the base speed listed there (0.78GHz vs 2.59GHz) See here I suspect that this may be largely what is causing my problems.

I have tried the following things to bring this speed closer to my base speed:

• Moving the power management slider to "Best performance" See here
  
• Increased the minimum processor state when plugged in to 100% See here
  
• Turned off Speedstep in my Bios (which is described in the BIOS as forcing my CPU into its maximum performance mode
  
• Turned off C-states in my BIOS which is described in the BIOS as allowing the processor to be put in other performance modes
  

Notably I have been trying the fixes recommended in this thread: Maximum Processor Speed Lower Than It Should Be

Any advice on steps I can take short of reinstalling Windows is greatly appreciated!

DL speed drop

Hi,BenjaminMello

My name is Erik. I'm an Independent Advisor and I'll be glad to help you today.

How many devices that are connected to the internet, possible that you been experience a high traffic connection to your internet,that's why the speed drop while you were downloading and if only one device is connected, I suggest to run a speed test, make sure
to get the download speed and then the Upload speed, if the Upload speed getting only 1mbps and then you have an issue to your connection, and I suggest to contact your service provider and to trace your line connection and asked what is the upload standard
upload speed that you have in the package of your internet, because if your getting a 40 Mbps of speed expect the upload speed should be more than 5 Mbps to 10 mbps.that will depend what packaged that

 

CPU and GPU clock speeds drop under load

I'm having a weird problem with my laptop where, every few seconds during playing high-load games, the CPU and GPU both drop speed sharply for a second, causing a big slowdown in framerate. (For instance, the CPU speed will suddenly drop from about 3.4 GHz
to less than 0.8 GHz). At the same time, the screen's brightness will dip as well, which suggests to me that it's related to my power settings. It also seems to happen more frequently when I'm charging a low battery than when the battery is full - I've even
had it happen while streaming video when I'm charging from a low battery.

I've tried switching my power plan settings so that everything is the same for "On battery" and "Plugged in", which solves the brightness changing but does not solve the speed drop. I've also tried monitoring the temperatures of the GPU and CPU but they never
seem too high. I've tried clean installs, updating drivers, etc. I don't have anything overclocked. I've had the laptop for a about a year and the problem is quite new, and seems to be getting worse.
