I have tried the offset but it looks complicated. Should I turn off Turbo Boost? How should I manage this? What really does the offset do? The min offset is 0.800v and I don't know how it works.
You can have the best of both worlds. Just set your Turbo Ratio to the desired overclock, set you CPU ratio to AUTO, and use the Offset CPU Voltage instead of manual. The offset adds to your VCore when your CPU asks for a certain voltage from the Mobo. It will basically add the offset voltage to the VID voltage that the CPU would require. You will just need to find the offset voltage that will supply the CPU with enough power to reach your desired overclock (I use +.0700 for instance, and this will translate into about 1.368 under stress testing). You can only use it on the 100 strap, but at 4.3 that should not be an issue. Enable Speedstep, and the C states, and your voltage will drop with your clocks. So to get it to work, your need to follow these rules:
- Bclk strap of 100 (you can adjust the Bclk If you want to clock higher than 4.3Ghz. I run at 105 x 43 = 4515).
- Use the Offset Vcore. Manual Vcore will override any power saving features.
- Enable "C" states and Speedstep.
