EDIT: try checking in kombustor .. it shows the vddc levels ..the slider in afterburner is at 1.15V ..but kombustor shows only 1.05 and i just restared the system ..got a bsod ..i am guessing that voltage was too low..anyways uninstalled afterburner..system is fine.. but it does mean that changing voltage values in afterburner is having no effect
You have to enable "unofficial overclocking" to have voltage control. After changing the voltage, hit "apply" for it to take effect.
This is how to enable "unofficial overclocking" http://forums.guru3d.com/showthread.php?t=338906
You will need to disable ULPS too;
1. Go to regedit (start > search programs and files > "regedit").
2. In drop down menu: find file > type "enableulps".
3. For ALL instances (keep pressing F3) change the "1" value to a "0".
4. Reboot PC.
