I have a another problem now.
I thought that after 1.043 i was getting a good set up for constant overclock without classified tool but most of games hits power target so I can't do 1.068v because it's even worst.
This is what I'm using but I have to do something to increase the power usage or lower the overclock and voltage (i don't want to because temps are very good).
Vbios: LN2.
GPU 2160mhz @1.043v
VRAM 1164mhz
Max power draw is 460W (gpu-z shows power limit).
Port Royal 14725.
Any ideas to improve this power limit problem without having to lower voltage?
