ASUS X99-DELUXE II Series BIOS Manual
When the Ai Overclock Tuner is set to [Manual] or [XMP], the following items appear.
CPU Strap
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.
Conguration 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
This item allows you to select the source clock based on the assigned CPU
strap for a better overclocking capability.
Conguration options: [8Ohm dbl] [7Ohm dbl] [6Ohm dbl] [5Ohm dbl]
[4Ohm dbl] [3Ohm dbl] [2Ohm dbl]
PLL Selection
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.
Conguration options: [Auto] [LC PLL] [SB PLL]
Filter PLL
Set this item to high BCLK (base clock) mode when using a very high BCLK to improve
overclocking capability.
Conguration options: [Auto] [Low BCLK Mode] [High BCLK Mode]
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. The values range from 80.0 MHz
to 300.0 MHz.
We recommend you to set the value based on the CPU specication, as high BCLK
frequencies may damage the CPU permanently.
Initial BCLK Frequency
This item allows you to set the initial BCLK (base clock) frequency to start overclocking
to the assigned BCLK frequency. Use the <+> or <-> to adjust the value. The initial
BCLK frequency cannot be less than 80.0 MHz.
ASUS MultiCore Enhancement
[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.
