Overclocking 940MX

[adamuso]

Hey

I want to ask for some tips for overclocking my 940mx in msi laptop 

specs are i5 6300hq, 940 mx 2gb, (both tim changed for thermal grizzly conductonaut) 8 gb mem, and 120 w adapter,

I've tried some modest overclocking that is +30 mhz on core and 350 mhz on mem. clocks it's fully stable, and temps are great 63° to 69° C 

But i've run into issues with power delivery(i think) because when i have power seting of laptop on balanced gpu has power limit (1) but when i switch to high performance power limit goes to 0 but the voltage limit replaces it (1.2 volts), i think i can go higher with more voltage is there some trick to unlock voltage control (using evga xoc(could switch to something else if it works)

I don't know if it is the power adapter or only power delivery for the gpu

Just crank it till it crashes

it does on not much higher. But i think it's due to not enough voltage.

you can try Kepler Maxwell BIOS tweaker (there are guides on how to use it), but dont blame me if you burn the VRMs and the dGPU dies.

The PSU is most likely insufficient. The VRMs can't push power that's not there.

 

Depending on the game you might want to underclock/undervolt your CPU and crank the GPU

i have acces to dell 330w do you think that might help ? (idon't know the voltage of that one or conector) but i'll try it in course of next week

edit : looked it up on amazon it has right voltage.

Dell uses a standard power plug so I think you should be fine. Just know that without knowing VRM temps you might be shortening the lifespan of the board unknowingly. Core temps are not the same as VRM temps

How does the vrm's look like ?(it's close to gpu i assume)  i can open up the laptop and  stick a probe onto it. If it helps somehow.

That's easy to Google. It shouldn't be necessary, just be aware that it is a risk. They won't just die, but the total lifespan might be shortened if you increase voltage a lot. If you overclock moderately you'll be fine
