4.4.1 Using ASUS TurboV
ASUS TurboV allow you to overclock the BCLK frequency, CPU voltage, IMC voltage, and
DRAM Bus voltage in WIndows
®
environment and takes effect in real-time without exiting and
rebooting the OS.
Refer to the CPU documentation before adjusting CPU voltage settings. Setting a high
voltage may damage the CPU permanently, and setting a low voltage may make the
system unstable.
For system stability, all changes made in ASUS TurboV (except for Auto Tuning) will not
be saved to BIOS settings and will not be kept on the next system boot. Use the Save
Prole function to save your customized overclocking settings and manually load the
prole after Windows starts.
• Set the CPU Ratio Setting item in BIOS to [Auto] before using the CPU Ratio function
in TurboV. See Chapter 3 for details.
• For advanced overclock ability, adjust rst the BIOS items, and then proceed more
detailed adjustments using TurboV.
