Download :

after that… open it,

Go to Voltage TAB, then show :

VDDC = V gpu 1.3125 by default

???       = V RAM (  i think  ), don’t touch this ! not recommend….as we know better OC GPU than MEM  in ATI..

My RIG :

-e84 @ 4 GH

-4890

-4 GB kit FSB  5/5/5/12 ( 5 : 4 )

-CORSAIR TX-850W

VANTAGE

MAX OC on def Voltage 1.3125 ( see current voltage on TechPowerUp GPUTools )

up to ……4890 @ 975/1150

GPU SCORE : 12.081

Now to reach GPU 1000, ill have to increase vGPU up to 1.375v

GPU SCORE : 12.322
