From the way you formed your question, you need a lot more background knowledge before you start tinkering. If you use those settings with a stock cooler you'll highly likely burn your CPU. There is no single setting that works for all configurations. Not only are all chips different, the power supply, motherboard, RAM all influence the overclock.
Edit: Ok you have water cooling. That's good. But you only want to increase your voltage as you notice stability dropping with the higher clocks... Short version:
Increase CPU multiplier by 1 step, test for 15 minutes with Prime 95
Repeat until Prime95 gives errors.
When there's an error, increase voltage 1 step, test again, repeat until no more errors occur
Start increasing multiplier again.
Follow this until you can go no further. Your limits are your temperature (~62 degrees) and your voltage (1.55v).
