The frequencies of the GT 525M have been lowered. How to fix?

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
As I understand it, this was done in order to save on cooling, because even at the current overclocking, the video card heats up to 90 degrees. But in this scenario, my video card is comparable in performance to the HD 3000, which is rather unpleasant. I installed additional cooling, and now even when overclocking, the temperature of the GPU and CPU does not rise above 70 degrees at full load.
I tried to overclock, got the following results
Clock speed: 650 MHz
Shader frequency: 1300 MHz
Memory frequency: 1000 MHz
Pretty good, no artifacts, the temperature does not rise above 70 degrees. But if you play, for example, BattleField 3 at these frequencies, then after 10 minutes the computer simply turns off abruptly. I tried to turn it down, but stable work comes out only at these frequencies
Clock frequency: 570 MHz
Shader frequency: 1140 MHz
Memory frequency: 870 MHz
It doesn't even reach standard frequencies. I overclocked everything with MSI Afterburner, NVIDIA Instector, RIVA, and standard NVIDIA tools. The driver tried both the old 290 and the new 327.65. But in Windows 8.1, overclocking is higher than in Windows 7, which is rather strange.
Maybe it's the voltage, my vidyuhi has 0.9v, although for example here www.youtube.com/watch?v=I6mWrtS69Xw the voltage is 0.83v.
Here I made screenshots in different working conditions.
Standard frequencies, no overclocking.

Stable overclocking, in which the laptop does not turn off.

Unstable overclocking, in which the laptop turns off after 10 minutes.

How to raise the frequency, at least to the standard values?
Thank you!

Answer 1

Toshiba engineers know better, so bring back the native frequencies (which is the best solution) or at least keep the overclock stable.
P.S. I can't understand why you're fighting here? Well, perhaps only for unstable operation and wear of the video card ...
