Tweaker
Whether the system will work stably with the overclock/overvoltage settings you made is dependent on your overall system configurations. Incorrectly doing overclock/overvoltage may result in damage to CPU, chipset, or memory and reduce the useful life of these components. This page is for advanced users only and we recommend you not to alter the default settings to prevent system instability or other unexpected results. (Inadequately altering the settings may result in system’s failure to boot. If this occurs, clear the CMOS values and reset the board to default values.) & CPU Clock Control Allows you to manually set the CPU base clock in 0.01 MHz increments. Important: It is highly recommended that the CPU frequency be set in accordance with the CPU specifications. & Async CPU/PCIe Clock Allows for asynchronous CPU/PCIe clock. & CPU Ratio Mode Allows you to set the core ratio for all CPU cores or individual cores. & CPU Clock Ratio Allows you to alter the clock ratio for the installed CPU.
