How can I set up offset mode correctly so that when it's on idle speed, the voltage drops down to stock? which is 0.98 I believe.
My favorite way is to set Load-Line Calibration to Ultra High, and then open Real Temp and click this button to see the VID:
The VID's purpose is to find the Offset by finding the difference between the VID you see and the core voltage that you want. However, be aware that there is a chance you may need to put load on the CPU in order to see your true VID.
The core voltage that you want is the voltage you want to see in CPU-Z under full load.
Also, disable CPU C3 Report and CPU C6 Report as well because this will avoid BSOD's and system lock-ups while idling or during low load. Disabling these two prevents the core voltage from going too low (so, it raises the "floor" just a little bit so that it's not too low).
