UNDERVOLTING GPU

[D-ray]

Hello everyone! After researching everything about why my laptop overheats (playing things like Super Meat Boy [???]), I have discovered that my problem might be caused by my GPU.

People say that undervolting it reduce the temperature and the useless amount of usage from the graphics card. I'm not particurally expert in this things, as you can see how I'm writing.

I tried using MSI Afterburn but they told me that I can't use it because my graphics card is not compatible. My graphic card is a GeForce 940MX.

If you have any tip or advice that could be useful, answer me!
It's been a YEAR since I have this problem, and I have played all of my cards...

If control+f doesn't open a frequency/ voltage curve then that means your GPU does not support it. Best thing to do is to clean your laptop with compressed air and if its not hard to disassemble you can replace the thermal paste with a something decent.

There is NO OTHER WAY?
The pc is clean as new...

There's nothing you can do about that, I'm afraid. It's a mobile GPU; you don't have access to the same kind of controls as you would on desktop.

Even if you could undervolt, you're still going to have problems. And you'll have new issues; undervolting dramatically reduces performance, and it can cause crashing.

Mmph... 4 years of savings, for a useless pc...
Thanks Lenovo.

Whatever, thanks for your fast answer.

Just use vsync to cap framerate at 60. That way you should not max out your gpu on simple games like Super Meat Boy.

How I can do so?

Overheating is an endemic problem on all laptops, there's really not much anybody can do about it. Cooling pads help, and the newer Pascal models generally run a bit colder.

PC parts are designed to run in an open environment with big heatsinks for each major part; cramming them all into a tiny airtight box, shovijgn them up against each other and running multiple parts off a single heatsink is a recipe for disaster. It's also a recipe for a laptop.

VSync is an option in the settings in all games. Just enable it and done.

Also, is your laptop the Lenovo Ideapad 320? One with i5 7200U and Geforce 940MX.
I have that laptop and the temperatures drastically dropped when I changed thermal paste.
It is REALLY easy to change them on that laptop.

No, it's Ideapad 510-15lKB.

Cheap "GT" cards don't support it; get a better GPU; like GTX 1060 or better.
Or even a used 970/980/980 Ti perhaps which are still very good.

You might want to look up the disassembly of that laptop to change the thermal paste. It's usually one of the most effective method to reduce overheating. Factory applied pastes usually are not that good.

^^ Yea just duct tape a 980Ti to the laptop maybe it'll work who knows ( ͡° ͜ʖ ͡°)

It's pointless to even bother trying to OC a Mobile GPU anyways.

With an i5 (especially a U model) + 940MX, there really is no good reason it should be getting "too hot" given it's all low end parts there.

If the laptop is over 1-year old and struggling to stay under 90*C, then I'd suggest an internal fan replacement, blowing out all the dust, and new thermal paste.

Helps to always elevate the Laptop as well when in heavy usage, like Gaming.

I know and good luck trying that on the OP's laptop which doesn't have any thunderbolt 3 connector at all.

That's not true, undervolting usually doesn't reduce performance, it can even increase it at times (due to the lower temp preventing throttling). You might be thinking of underclocking, that can lower performance. This is not a hard thing to look up.
