ASUS Z77-A Manuel D’Utilisation

Chapter 2: BIOS information

2-16

This item appears only when you set the EIST item to [Enabled].
[Enabled] 

Allows processor cores to run faster than marked frequency in specific 

conditions.

[Disabled] 

Disables this function.

The following three items appear only when you set both the EIST and Turbo Mode items 

to [Enabled].

Long Duration Power Limit [Auto]
Use the <+> and <-> keys to adjust the value.
Long Duration Maintained [Auto]
Use the <+> and <-> keys to adjust the value.
Short Duration Power Limit [Auto]
Use the <+> and <-> keys to adjust the value.
Primary Plane Current Limit [Auto]
Maximum instantaneous current allowed at any given time for CPU cores.

Use <+> and <-> key to adjust the value at 0.125A increment.
Secondary Plane Current Limit [Auto]
Maximum instantaneous current allowed at any given time for Internal Graphics cores

Use <+> and <-> key to adjust the value at 0.125A increment.

Load-line is defined by Intel VRM spec and affects CPU voltage. The CPU working voltage 

will decrease proportionally to CPU loading. Higher value gets a higher voltage and better 

overclocking performance, but increases the CPU and VRM thermal. This item allows you to 

adjust the voltage range from the following percentages to boost the system performance: 

0% (Regular), 25% (Medium), 50% (High), 75% (Ultra High) and 100% (Extreme).
Configuration options: [Auto] [Regular] [Medium] [High] [Ultra High] [Extreme]

The actual performance boost may vary depending on your CPU specification.

Frequency switching affects the VRM transient response and the thermal component. Higher 

frequency gets quicker transient response. Use the <+> and <-> keys to adjust the value. The 

values range from 200k Hz to 350k Hz with a 50k Hz interval.

DO NOT remove the thermal module when switching to Manual Mode. The thermal 

conditions should be monitored.
