GTX 1050 4GB DDR5 - Overclocking graphics card in a laptop - temperature and vol

Hello all!
I have a question about overclocking the graphics card in a laptop

My graphics card in the ACER laptop is GTX 1050 4GB DDR5, I turned it up with MSI AfterBurner.

During overclocking, of course, the temperature and the increase in voltage - grew steadily. After reaching the maximum overclocking limit of my card without artifacts or crashing FurMark, the voltage dropped from what I remember about 0.5V and the temperature dropped from 65 degrees to 60 and so all these times remain with the clock overclocked and the memory of the GTX 1050 graphics card overclocked.

Is it normal for the temperature and voltage of the card to drop after overclocking? Should I get ready for something terrible?

Photos and results of overclocking can be shown but only at about 17 when I return home from work.

Greetings to everyone and waiting for an answer.

No overclocking

As for the nickname - lol.

Quite normal behavior for senseless OC ... besides, test something normal because nothing of your OC since VRAM is slow without talking about power card locks.

What do you advise to test? I can't unlock the power limit and temp. Sliders in my MSI AFTERBURNER, and I have a laptop. Can it somehow unlock this?

For testing, for example, Unigine Valley: https://benchmark.unigine.com/valley.

Show the second GPU-Z tab after the test (not necessarily in the Valley, maybe some 3dmark or similar). It is mainly about what will be the core voltage and max core clocking.
In Furmark they will always be lower, because this program is a "heater", such a load you can not get with normal use of the computer.

Unlocking the sliders will do nothing, because you can reduce the limit, not increase it, and the temperature is low, so raising it will not change anything ... The only thing you can play with the frequency / voltage curve - you do not move the slider responsible for the clock core , you just click on these small bars on the left of the slider (alternatively the keyboard shortcut Ctrl + F).

Regarding memory, this ~ 2170 MHz is quite a lot, and performance (almost) will not increase. Leave 2000MHz for example and focus on the core clock speed.

Are you saying that memory is no longer profitable just like something the core clock lift?

That's right, do core timing.

And how does the case look with the card? Can you show off I have an identical card so I'm curious about the results.
