Check allow/monitor voltage control.
Edited the cfg file to change EnableUnofficialOverclocking from 0 to 1.
To enable VRM detection on a EAH5870V2 add the following text to your hardware profile file (.\Profiles\ VEN_1002&DEV_6899&SUBSYS_034E1043&REV_00&BUS_1&DEV _0&FN_0.cfg):
[Settings]
uP6208_Detection = 1
Shut down / Restart Afterburner and you should see +12 for core voltage. +12 equals 1.212v stock voltage. When you increase past+12 it will add an additional % to your stock voltage.
example: +18 equals 1.218v 3d
Use GPUZ 0.4.3 to monitor voltage
For max voltage you'll need to use smart doctor.
