You have two options, use the auto OC provided by either the BIOS or the auto OC software provided by asrock if they have one for your motherboard.
The other option which you may not like is overclocking it manually which is far better in my experience by using a overclocking guide like this one:
The CPU Core Voltage modes are used to fine tune your CPU voltage with different kinds of profile. The three most common ones are:
- Manual (Manual, static set core voltage, can be influenced by Intel C-States like C1E, C3, C6/C7, Enhanced Intel Speedstep Technology to have a lower than desired CPU voltage on idle)
- Adaptive (The CPU voltage will ramp up on load and go down on idle, increasing the core multiplier will have an impact on CPU voltage by increasing it proportionately.
- Offset (This is used for when you want to add an offset to the VID (The CPU voltage requested by the CPU which is then read by the motherboard). The motherboard decides how much CPU voltage the CPU gets and not the CPU itself when offset is used. Basically you have either a + or - offset. Minus offset is used when you want the actual CPU voltage to be lower than the VID. A positive offset is used when you want to increase the CPU voltage higher than the CPU VID.
Now the VID varies depending on load and you can find out your stock VID by disabling all power saving settings in BIOS such as EIST, Intel C-States and running the windows power plan in high performance mode. You can check if this is active via Control Panel > Power Options > High Performance.
Once you got it all set to find VID use a program like HWMonitor, HWinfo64 or CPU-Z to find out what the CPU voltage is at on load. Once you find that out that is your stock reported VID read by the motherboard from the CPU.Edited by benjamen50 - 7/3/16 at 7:52am
