I'm working with an Asrock Extreme6 and i5-3570K. At stock bios settings, both CPUZ and Real Temp show quick fluctuations in core speed even at idle.
Like at 1 to 3% CPU usage, I'm seeing Core Speeds between 3200 to 3440 MHz on real temp
With CPUz, it gets into the turbo range of up to 3700 MHz, and this is at idle. These fluctuations happen about every second. It does not seem to downclock like it should. Not seeing below 3200 MHz with real temp
With prime95, it pegs at 3600 MHz and stays there. Bios has been updated. Any ideas on this?
EDIT...I found it. Installing the Asrock utility adds another power management option in Win 7, and it disabled speedstep.
