Overclocking Presets
Select this item to load various settings suitably tuned for your needs.
Ai Overclock Tuner
Allows you to select the CPU overclocking options to achieve the desired CPU internal
frequency. Conguration options:
[Auto] Loads the optimal settings for the system.
[Manual] Allows you to individually set overclocking parameters.
[D.O.C.P.] Allows you to select a DRAM O.C. prole, and the related parameters will
be adjusted automatically.
The following items appear only when you set the Ai Overclock Tuner to [Manual].
BCLK Frequency
This item allows you to set the BCLK (base clock) frequency to enhance the system
performance. Use the <+> or <-> to adjust the value.
We recommend you to set the value based on the CPU specication, as high BCLK
frequencies may damage the CPU permanently.
