Does it allow you to go up to 20%? My 250w 780 only allowed for 10% (275W)
TBH when Gaming, this card isn't often limited by power. Although it might end up being if I can get the voltage above 1v.
In nvinspector I can go up to 20%. On the Maxwell Titan it was lower. I've gotten that Titan to nearly 400w with a BIOS mod. It happened even in Fallout 4. The perfcap reason is power limit reached.
With this card I'll first have to put the hybrid cooler on it and wait for BIOS mods. I wonder if 2100 is a hard limit though. I could get 2100Mhz easily and it ran perfectly but when I added even 20Mhz it crashed Heaven. Of course I tested this with 100% fan. I'm not taking any chances.
