1.6v on gpu core?

[Wardaddy755]

Hello, I'm trying to understand the voltage table in maxwell bios tweaker 2, as far I know the card runs at 1.2v right? Then why is there 3 columns with 1.6v max?? Wanted to undervolt the card a bit to have it always under 70c, but I'm not sure what to touch   I already undervolted the cpu and llc by -100mv and temps dropped by 6c. Also in gpu-z card only hit 1v at full load with 1038mhz, in case I brick the card I can just flash it back with a bootable right?

there are 2 rows at the bottom thats the max voltages across the board.

If you don't know what you're doing, why are you playing with voltages at all? You know a lower voltage won't automatically mean the card is actually stable, right?

I believe you can't directly control voltage on Pascal cards. They will auto adjust no matter what. 

The only way you could make this happen would perhaps, be a custom VBIOS?

 

Yup: 

The voltage for the pascal cards (1060, 1070 and 1080) is locked at 1.093v.
there is no way to go higher. 100% in MSI afterburner just allows the card to go all the way up to 1.093 if the thermals allow it.

This is how the bottom looks, so that 1.6v isn't a bug right? is for the memory or something else therfore I could just leave it as it is?

Please read my post before replying!

It's clear that the voltage table is for the different clock speeds, but didn't find info anywhere about the 1.6v sliders and why pc reports 1v max while the bios has 1.2v sliders in it, what do you think?
