Underclocking GPU

[Roboslash1]

Hi,

 

I have had recent problems in GTA V, so support recommended me to underclock both memory and base clock by 20 mhz. One question is, does underclocking my Gpu b 20 mhz void my warranty, and after applying the underclock, do i have to have the OCII from gigabyte open each time in order for the overclock to stay? 

 

Thanks a lot. 

 

And also, how much less performance will I get with -20mhz?

Btw, when I underclock with OC GURU II, and then apply and restart my pc, the next time I open OC GURU II, it shows the clock speeds before my underclock. How can I make a permanent underclock?
