Asus z97-k/usb 3.1 [54/91] Asus multicore enhancement auto

PLL Selection [LC PLL]

By default, this item is set to [LC PLL] for better stability. Set this item to [SB PLL] when

BCLK (Base Clock) frequency is below 100MHz, which may affect the functionality of other

devices that need precise clock jitters. Conguration 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. Conguration 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 specication, 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.

2.5.2 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.

2.5.3 CPU Core Ratio [Auto]

This item allows you to set the CPU core ratio limit per core or synchronize automatically to

all cores. Conguration options: [Auto] [Sync All Cores] [Per Core]

When the CPU Core Ratio is set to [Sync All Cores] or [Per Core], the following items

appear.

1-Core Ratio Limit [Auto]

Select [Auto] to apply the CPU default Turbo Ratio setting or manually assign a 1‑Core Limit

value that must be higher than or equal to the 2‑Core Ratio Limit.

2-Core Ratio Limit [Auto]

Select [Auto] to apply the CPU default Turbo Ratio setting or manually assign a 2‑Core Limit

value that must be higher than or equal to the 3‑Core Ratio Limit.

If you assign a value for 2‑Core Ratio Limit, do not set the 1‑Core Ratio Limit to [Auto].
