Buddy has a HP Envy Phoenix PC what has very limited overclocking in the bios. It has a liquid cooling system on the i7-4770k. In the Bios there are only these options for over clocking with the current values we are using now:
CPU Power Limit1: 95
CPU Power Limit2: 119
1 Core Ratio Limit: 41
2 Core Ratio Limit: 41
3 Core Ratio Limit: 41
4 Core Ratio Limit: 41
From what I have figured out. The Ratio Limits are the multiplier the FSB. basically 41x100 = 4100mhz. I think the Power limit settings are wattage? I know the i7-4770k comes stock at 84w TDP. So I am assuming the Power Limit 1 is the lower limit wattage and from my reading the Power limit 2 should be set to 20-25% above it. Is that correct?
Basically, how do you know what to set the wattage to without underpowering or overpowering it? Is there a rule of thumb for the multipliers and how much wattage? Also what is the absolute max the wattage should ever be set to?
Thanks for you time,
Mike
