When the Ai Overclock Tuner is set to [Manual] or [XMP], the following items appear.
CPU Strap [Auto]
This item is default set to auto for a corresponding BCLK (base clock) frequency
adjustment. Manually select a strap value close to the target BCLK frequency for an
extreme overclocking.
Conguration options: [Auto] [100MHz] [125MHz] [167MHz] [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.
Conguration options: [8Ohm dbl] [7Ohm dbl] [6Ohm dbl] [5Ohm dbl]
[4Ohm dbl] [3Ohm dbl] [2Ohm dbl]
PLL Selection [Auto]
This is default set to LC PLL for a better stability. Select SB PLL when BCLK (base
clock) frequency is far away from 100MHz, this may affect the functionality of other
devices which need precise clock jitters.
Conguration options: [Auto] [LC PLL] [SB PLL]
Filter PLL [Auto]
This item allows you to select a high BCLK (base clock) mode when using a very high
BCLK to improve the overclocking capability.
Conguration options: [Auto] [Low BCLK Mode] [High BCLK Mode]
BCLK Frequency [100.0]
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 40.0 MHz
to 500.0 MHz.
We recommend you to set the value based on the CPU specication, as high BCLK
frequencies may damage the CPU permanently.
Initial BCLK Frequency [Auto]
This item allows you to set the initial BCLK (base clock) frequency to start overclocking
from the assigned BCLK frequency. The frequency may not be less than 80.0 MHz.
The values range from [BCLK frequency-15.0MHz] to [BCLK frequency]
When Ai Overclock Tuner is set to [XMP], the XMP mode supported by the installed
memory module is displayed.
ASUS MultiCore Enhancement [Auto]
[Auto] This item allows you to maximize the oveclocking performance optimized
by ASUS core ratio settings.
[Disabled] This item allows you to set to default core ratio settings.
