Best method for overvolting pascal in Clevos

I've basically been out of the loop with Pascal until now, so this is probably a stupid question.

I can't get much beyond a 150mhz OC on a GTX 1080 without needing more voltage. My temps max out at about 55C, so I have a lot of thermal headroom. Both NV Inspector and MSI afterburner won't allow me to mess with the voltage.

What's a good way to mess with the TDP/Voltage? Is Mobile Pascal TDP Tweaker the only answer? Is there anything that doesn't require a vbios flash?

 

You can't.

 

You can't as in period, or Mobile Pascal TDP Tweaker is the only way?

 

You can't as in period.

Not even with mobile pascal tweaker. All the tool does is raise the TDP making the card being able to use more watts. So it clocks higher with higher voltage due to having higher TDP and GPU Boost wants to boost, but you cannot overvolt the card to run more stable.

Basicially if GPU Boost 3 doesn't want you to use more voltage, then you're not getting more voltage. maxwell was the last card series from NVIDIA that actually let you control voltage per clock.

 

Only custom vBIOS with more power limit.

 

You'd need to use the Mobile TDP tweaker to increase TDP first.

Then you can use the voltage curve in afterburner to fine tune clocks with voltage. You can probably undervolt and still runs stock clocks fine.

Might even be able to OC with an undervolt. With an increased TDP you should be able to go beyond 150Mhz but voltage is pretty much locked.

 

Increasing TDP will actually reduce how much core offset you can add before becoming unstable, since with the extra power headroom the card will boost higher at stock on its own. But the end result will be higher.

 

I overvolted my 1080 through hardmods and all I ever got was more power draw. 1.062V is already a very high voltage for Pascal with abysmal scaling with even more voltage.
