My current main system is a Phenom II X4 955 and with that, at idle the CPU will generally stay at 800Mhz whilst the CPU is below 25% and even then very brief spikes won't cause it to increase.
I've just built a Asus Z97-A/i5 4670k system (OC'd to [email protected]
) and with this, cores 2&3 seem to spend most of the time around 1400-1700Mhz, in fact core 1 has joined in now, so only core 0 seems to mostly stay at 800mhz, even though the CPU usage is below about 8% and the cores below about 10%. I've also noticed the core VIDs and Vcores stay at fixed voltages, unlike my AMD system where they decrease at lower clocks to save energy and reduce heat.
I'm sure I'm overlooking some BIOS setting due to being an Intel noob but is there a way to make the CPU step up less aggressively and also reduce the VID/Vcore when running at below full speed?
