Are Throttlestop Values Temporary?

[MetalZero]

Hi,

My laptop is getting warm too much and I decided to undervolt its 9700K (no iGPU variant).

I have used XTU but it resets after a restart because of the bios. I am now underclocking with ThrottleStop but I have some questions.

Are the throttlestop voltage values temporary or software sided? (When I close the program or restart windows are my voltages going back to default if I don't autostart the program?)

Thank You

Unless you mod the BIOS, nothing will be permanent without software - be it XTU or Throttlestop - enabled.

Also - you may want to downclock, not just undervolt

Thank you but when I quit throttlestop with disable turbo enabled (with "do not reset fid/vid" unchecked, so it should reset) it does not revert back to turbo frequencies. I generally turn off throttlestop but just curious.

When you exit ThrottleStop, it generally leaves your CPU as is.  If you selected Disable Turbo or you lowered the Turbo Ratio Limits, these settings will continue after you exit ThrottleStop. 

 

The Do Not Reset FID/VID on Exit option only refers to the Set Multiplier values which are not used if you have Speed Shift enabled (SST in green).  The VID refers to the voltage VID in the old Core 2 Duo based processors.

 

After you exit ThrottleStop, any changes that you made with ThrottleStop can then be changed by Windows or any other software running on your computer.

 

The ThrottleStop voltage values are software based.  ThrottleStop does not interact with the BIOS in any way.  If you do a sleep or hibernate and ThrottleStop is not running, generally when you resume, your CPU voltages should be reset to their default values.  You can test this by leaving HWiNFO or HWMonitor open on your desktop to monitor the offset voltages before and after you resume.

Throttlestop works by setting specific registers in your CPU that define the power plan. When you close it, there is no task to reset these registers back to the default settings. If for any reason your BIOS re-posts (S3+ resume), or another program makes changes to the resisters, the value will change (defaults as set by the BIOS in a resume, or per the program making the changes) after Throttlestop is closed.

So to answer your question, unless Throttlestop (or other likewise program) is run at boot time or by the user, the CPU is always initialized per the BIOS settings.
