CPU Strap [Auto]
This item allows you to select a strap close to your target BCLK (base clock) for an extreme
overclocking, or leave it at [Auto] for the BIOS to upgrade. Configuration options: [Auto]
[100MHz] [125MHz] [166MHz] [250MHz]
The following item appears only when you set the CPU Strap to [100MHz], [125MHz],
[167MHz], or [250MHz].
Source Clock Tuner [Auto]
This item allows you to select the source clock based on the assigned CPU strap for
a better overclocking capability. Configuration options: [8Ohm dbl] [7Ohm dbl] [6Ohm
dbl] [5Ohm dbl] [4Ohm dbl] [3Ohm dbl] [2Ohm dbl]
PLL Selection [Auto]
This item is set to LC PLL by default for better stability. Select SB PLL when the BCLK (base
clock) frequency is far away from 100 MHz. This may affect the function of other devices that
need precise clock jitters. Configuration options: [Auto] [LC PLL] [SB PLL]
Filter PLL [Auto]
Set this item to high BCLK (base clock) mode when using a very high BCLK to improve
overclocking capability. Configuration options: [Auto] [Low BCLK mode] [High BCLK mode]
BCLK Frequency [Auto]
This item allows you to set the BCLK (base clock) frequency to enhance the system
performance. Use the <+> or <-> to adjust the value. The values range from 80.0 MHz to
300.0 MHz.
We recommend you to set the value based on the CPU specification, as high BCLK
frequencies may damage the CPU permanently.
Initial BCLK Frequency [Auto]
This item allows you to start overclocking the system from the initial BCLK (base clock)
frequency to the assigned BCLK frequency. Use the <+> or <-> to adjust the value. The value
ranges depend on the value you set on BCLK Frequency.
