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 aer 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.

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

Because the UEFI soware 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.
