"CPU Core" undervolt test on I7-9750h. How it affect? Here.

[SaIazar]

Tested on helios 300 with aida64, 56w PL1 limit. Tested many values, and my excel-paint table shows the difference, imo 229.5 might be the best value.
Cache was on -125, but overall for me -127 is stable.

edit. also ill add my ts settings if someone interested.

imo 229.5 might be the best value.

Other users have come to the same conclusion. Some stop at -200 mV because it is a nice round number. Somewhere around -220 mV to -230 mV seems to be optimum.

The HWiNFO MHz data is only accurate to +/- 100 MHz. You would be better off using the ThrottleStop log file data. It uses high performance timers within the CPU and can track the CPU speed (Multiplier) to a much higher level of accuracy.

Cinebench R20 has proven to be a great test when adjusting voltages. You should see better performance or better temperatures as the CPU core voltage goes from -125 mV to -230 mV. After -230 mV, most users see little if any increase in performance.
I will post a link to the other testing you did. Thanks for sharing.

My research about i7-9750h on Acer Predator Helios 300 (2019)

Hello, after nearly year of trying to understand ThrottleStop, sense how whole undervolt process and else features work I think, I can share my experience. Maybe someone will find this info useful. In advance, Im only lil Polish boy, im bad at english, also im too lazy to correct myself with...

Edit - Here is some Cinebench R20 testing a user sent me.
