ASRock z87 pro4: Chapter 4 UEFI SETUP UTILITY

Chapter 4 UEFI SETUP UTILITY

4.1 Introduction

ASRock Interactive UEFI is a blend of system conguration tools, cool sound eects

and stunning visuals. Not only will it make BIOS setup less dicult but also a lot

more amusing. is section explains how to use the UEFI SETUP UTILITY to

congure your system. You may run the UEFI SETUP UTILITY by pressing <F2>

or <Del> right aer you power on the computer, otherwise, the Power-On-Self-Test

(POST) will continue with its test routines. If you wish to enter the UEFI SETUP

UTILITY aer POST, restart the system by pressing <Ctl> + <Alt> + <Delete>, or

by pressing the reset button on the system chassis. You may also restart by turning

the system o and then back on.

Because the UEFI soware is constantly being updated, the following UEFI setup

screens and descriptions are for reference purpose only, and they may not exactly

match what you see on your screen.

4.1.1 UEFI Menu Bar

4.3 OC Tweaker Screen

In the OC Tweaker screen, you can set up overclocking features.

Because the UEFI soware is constantly being updated, the following UEFI setup

screens and descriptions are for reference purpose only, and they may not exactly

match what you see on your screen.

CPU Conguration

CPU Ratio

e CPU speed is determined by the CPU Ratio multiplied with the BCLK.

Increasing the CPU Ratio will increase the internal CPU clock speed without

aecting the clock speed of other components.

CPU Cache Ratio

e CPU Internal Bus Speed Ratio. e maximum should be the same as the CPU

Ratio.

BCLK/PCIE Frequency

e CPU speed is determined by the CPU Ratio multiplied with the BCLK.

Increasing the BCLK will increase the internal CPU clock speed but also aect the

English

clock speed of other components.

Enable Spread Spectrum to reduce electromagnetic interference for passing EMI

tests. Disable to achieve higher clock speeds when overclocking.
