I just got my new Intel 4670K and Gigabyte Z87X-D3H board.
Coming from an Intel Core2 Q6600 a lot of the new overclocking stuff is new for me. Now you mainly overclock with multiplier instead of FSB frequency.
The new cpu seems to be extremly energy efficient when idling. It goes down to a multiplier of 8 and core voltage drops to about 0.15V.
I tested my chip a bit with fixed voltages and stability tests and came to the conclusion that I want to run it at 4.3ghz (43 multiplier) with comfortable full load temps of 60° with max peaks at 70°. The VCore was set to 1.15V. CPU-Z showed a voltage of 1.176V at max load.
Now I am struggling to get my energy savings back. I want the VCore to drop back to about 0.15V when the system is idle.
- I tried setting the "Quick Boost" in the gigabyte UEFI to "medium", which resulted in 4.3ghz BUT the core voltage went up to 1.27V on load which makes my chip a bit too hot. It also does not fully drop to 0.15V in idle - minimum was about 0.7V.
- I also tried setting the VCore to "normal" and then setting a "VCore offset". I was able to get to my desired max core voltage, but the minimum voltage it went to when idling was about 0.8V which is still much higher than default.
Is there any option I missed that just increases the core voltage when it is actually needed in the higher multipliers on load?
Does the voltage even matter for actual power consumption? The chip has the same temperature when idling at 0.15V or 0.8V.
