Wanted to Know more about GPU undervolting and its feasibility

I have a Legion Y520 and it has Nvidia 1050ti GPU I came across several people where they recommended to under-volt the GPU to lower the thermal temperature and lag due to overheating!! Any guide or tips for my GPU where can i start and should I go ahead with it?? 

  • It's tricky the first few times you decide to try it out. So for first timers I would guess you also need to install a free stat tool called HWInfo64. It allows to see realtime and historical (as long as it has been running) peak and current temperatures and frequency of *** near everything in the system. Find the GPU section and check idle stats. Then run a game or benchmark to see what the maximum frequency and temp would be. Then in Afterburner you hit CTRL + F to open the frequency/voltage graph. Find a point you are targeting like 950mV and note what frequency it states for that voltage (something like 1600mhz etc) then every point AFTER needs to be reduced to match that which will allow the maximum voltage to be that same 950mV. The goal is to pick a point that is close to what your card default boosts to during those games/benchmarks and attempting to keep that frequency with around 100 or so less mV. You can also try to raise the memory frequency a slight bit as well although that is a little more tricky. Here is a little youtube video to show the process better than I can explain it to you. www.youtube.com/watch

  • Thanks mate!!  I'll try these steps and will get back to you. 

  • Hope this helped you... I will also say if you are trying to drop temps in general you can do the same for your cpu using a free tool called throttlestop. If your cpu is not unlocked then you wont be able to do much but that's okay as you only want to adjust 1 single thing only to undervolt your cpu and drop the temps by around 5 to 8 degrees as well without lowering performance. link to software here: https://www.techpowerup.com/download/techpowerup-throttlestop/

    Also if you want a quick video on what to adjust and by how much here: https://www.youtube.com/watch?v=QBNP5I2y668

    this video has a few different tips but just skip to the throttlestop section... as video indicates you can also use intel's own XTU software to achieve the same results.

  • So, I went ahead with the above solution and man I'm on 9th cloud. Earlier my CPU Temp would go as far as 90C and GPU will be following it to 80-85 C range but now I can see massive decrease in temp almost 8-10.C After lots of trial and error (and several BSOD) I finally settled for a sweet spot of -0.125 mv for CPU 

    I played "horizon zero dawn" for 2-3 hours and it was so stable and never went above 80C which is still good considering how heavy the game is.

    P.s- I under-volted both my GPU and CPU using msi afterburner and Intel XTU

  • awesome! not bad at all for the first time! next you can try to repaste your cpu and gpu if you dare to try it... that will also give you the chance to air out the heatsinks and wipe out the dust. that should help a bit more. wont really drop thermals much but your fan noise would drop slightly as it would take less rpm to produce the same level of cooling performance. arctic silver is good and so is thermal grizzly; not many will vouch for it but the noctua 2nd gen paste is also pretty good. 

  • Not my cup of tea LOL and moreover I can't risk voiding its warranty it's a new laptop!! so, I don't' think it will require a change of thermal paste but I'll keep them in mind for future reference . Thanks
