Pascal OCing (GTX 1080)

AFAIK one slowly increases the Core Clock and when it gets unstable you adjust the voltage accordingly.

 

I seem to be utterly unable to do that on my 1080. It OCs stabily +250 Core and +200 Memory, but the Voltage won't budge from 900mV +- 25mV. Is this normal behavior and I am just too concerned or is there something wrong?

What 1080 do you have and what tool are you using to overclock it?

Ah yeah, should have mentioned that. Its the PNY Blower Style GTX 1080 with the Morpheus II Core edition cooler. I am using MSI Afterbruner as of now, but I have also tried EVGA Precision X1 with basically the exact same results

Wait, nevermind. When playing a game the Voltage is at the appropiate levels, it was just during FurMark where the Voltage didnt budge.

that btw is because furmark and other power virus software hits the power limit very hard. They are no good for testing overclocks.

Alright, good to know. Was mainly checking for stability, but gaming seems to be more appropriate for that. I cant get higher than +255 @1.065V in games but in FurMark i easily got +300 stable
