how can i do mobile nvidia gpu undervolt?

[Ragnar Lothbrok]

Healthy days, I have a GTX 1650ti mobile graphics card.According to the gpu z sensor results, the tdp rises above 100% and the power limit occurs.how can i do undervolt to get rid of power limit? or alternatively what can I do?

Hello good forums, I have nvidia gtx 1650ti video card and I'm having some problems with games.
1-"No Load Limit" appears in the Limit Tab, how can I get rid of it?
2-I want to lower the wattage by making undervolt and correct the voltage curve, I need help on how to do it.
3-The peak point is higher when the voltage curve is idle, it drops after entering the game, is it normal? I added a screenshot.

I opened a similar topic before, but it didn't help much, I hope I don't get banned.

On my 1650 i use MSI Afterburner.

never had a NVidia mobile GPU but can't you just use MSI Afterburner and it's V/F Curve?

@GerKNG @droopyRO
I know it's done with msi afterburner but I don't understand where to start.

open the V/F Curve, hold shift and drag the whole curve down.
grab a point at your desired voltage, put it to the desired clockspeed and apply.

@droopyRO @GerKNG
yes, as you said, I have seen such videos, but there are a few points that I have in mind, I would like to ask them.
1-When the computer is idle, the afterburner curve is higher at every point than in the game, is this important?
2- While the graphics card works between 1800-1875 in low-load games, it works between 1650-1590 in heavy games, which one should I base on?
3-There is no load limit on the osd screen in the games, how can I solve this?

Make a couple of screenshots from in game with MSI Afterburner and RTSS running and one with your custom VF curve.

@droopyRO
is everything normal?

If i were you i would first limit the frame rate to 140 fps, you are way over your refresh rate in that first pic. And second, i don't see an undervolt there. Try 900mV or bellow, use this tutorial from 8:15 onwards

I did not do undervolt, this is when idle and under load situations vf curve -90mhz is decreasing this is normal? I've read that fixing fps in competitive games increases latency.
edit:The picture shows 1920, but before that it was 1950.

@Ragnar Lothbrok so even if afterburner doesn't do it, you can disable some cuda cores in Nvidia control panel. Or you can cap the framerate.

Is your laptop 140Hz?

No, 120Hz

You read, but did you try it, did you framecap that game and your kdr did go down ?

There's no such thing as "competitive gaming" and playing on a laptop. So get that thought out of your mind and cap your FPS at something reasonable.

No, no and no.
Before lowering the curve, you need to apply a negative offset to the Core Clock, like -300. THEN, you can choose the desired voltage point and go up till the desired point of frequency.

guess what "hold shit and drag the whole curve down" means...
a negative offset to the whole curve...

Oh well, think I misread then, sorry! That is correct

When I limit fps, the video card core clock drops between 950-1200, and the bullets in the game feel lagged. I also don't want the undervolt to lower temperatures, I want it to get rid of limits and get a stable experience.

 

[droopyRO]

It's normal to drop since your GPU is not 100% used. Just look at the screenshot you posted, that 44% is how much of your GPU is used. That is why you don't get the maximum frequency. Try running 3dmark Time Spy or a demanding game and see what your frequency is when your GPU is at 100%.
Also make sure your Vsync is off, because i am pretty sceptical you can "feel" the "bullets lag" at 120-140 fps ...

That's not how games work at all

"no load limit" simply means that the card drops it's clocks because there isn't enough load to justify it going up. To "remove" that, simply start a demanding task like a game, 3d rendering or compute tasks.
The card always has something that is limiting, that can be temperature, power draw, reaching the maximum clock in the boost table, lack of usage...

Basically the same as the system idle process for the CPU in task manager. That process is all the available CPU that is unused and thus in idle.

GPU makers simply decided to expose the aptly named no load limiter to the user. That way you know that it's casually sitting at 1300 MHz because there isn't any need to go higher, not because it's limited by power or temperature.

So obviously you won't see the "no load" indicator when playing games, because in those situation it should be either temperature, power draw, or the end of the boost table that is limiting.
