Custom voltage GT 525M. Is there a possibility to fix it?

Question

NVIDIA

Good afternoon. Two years ago I bought a laptop
Toshiba Satellite L755-A2W
here specifications www.notebook-center.ru/catalog_toshiba_15151.html
I chose a laptop according to its characteristics, they completely suited me. But recently I checked that the frequencies of the video card NVIDIA GeForce GT 525M are underestimated.
Here's how it is for me:
Clock frequency: 475 MHz
Shader frequency: 950 MHz
Memory frequency: 900 MHz
The original card (the one that is on other laptops, for example Dell Inspiron 15R ) is like this:
Clock frequency: 600 MHz
Shader frequency: 1200 MHz
Memory frequency: 900 MHz
If I try to overclock, then the maximum comes out510/1020/1098 , and this is not because it heats up, but because it just turns off immediately (the temperature is not higher than 75C ). It turns out that the video card picks up voltage. As it turned out, mine has a maximum of 0.9V and Dell Inspiron 15R , for example , 0.95V , it can still be freely overclocked to 835/1670/1080 .
Here I found the BIOS firmware for changing the voltage forum.notebookreview.com/dell-xps-studio-xps/63553... But if I'm not mistaken, this is only for Dell laptops , and put some unknown BIOS on my the car is a bit scary, and I don’t have an uninterruptible power supply, in case of problems with electricity I can stay for a long time without a laptop.
Please tell me why they did it and is it possible to fix it (if you are not afraid of overheating, this can be solved).
Thank you!

Answer 1

The idea is to change the bios.
Recently I came across an article for Dell Inspiron 15R
