When you get into the BIOS on the ASRock Z68 Fatal1ty motherboard, you are going to see a screen that is not what you are used to — instead of the typical blue BIOS screen, you have a graphical screen with buttons and a background, which is part of the Unified Extensible Firmware Interface (UEFI) BIOS that has started to become the new standard. The main screen when you get into the BIOS is where you are going to find information about what you currently have installed in your system, as well as the UEFI BIOS version. You get to know what processor you have installed and what speed it is currently running at, as well as which RAM slots are used and the size of each stick installed in the slots. In the bottom left-hand corner of the screen you are going to find the date and time, and when you move your mouse over to it and click on it, you are going to bring up the system date/time settings dialog box, which looks very similar to the dialog box that you would see inside of Windows. Along the top of the screen you are going to see click-able buttons that allow you to make your changes in the BIOS for system setup/overclocking. From left to right, you have Main Screen, OC Tweaker, Advanced, H/W Monitor, Boot, Security, and Exit.
Going into the OC Tweaker screen, you are going to be able to set the settings you would like to for the overclocking of your system. You have the Advanced Turbo 50, which is a setting that is used to help increase your system performance. When you are looking at the screen, you are going to see that you have Intel SpeedStep, Core Current Limit, Host Clock Override (which is your bCLK setting), and Spread Spectrum. Not all the options fit on one screen, so you can scroll down and get to the Voltage Control, which allows you to change the DRAM, PCH, CPU PLL, VTT, and VCCSA voltages. Under the voltage controls you have the ability to set user profiles. Up toward the middle of the screen you have the DRAM Timing Control screen that you can get into, and clicking this takes you to a new screen where you are able to load your XMP settings if you wish or manually set your RAM timings. Here you are also going to be able to set the operating frequency that you wish your RAM to operate at.
When you click into the Advanced screen across the top, you are brought to a new screen that has a list of different sub-screens you can get into; these are CPU Configuration, North Bridge Configuration, South Bridge Configuration, Storage Configuration, Super IO Configuration, ACPI Configuration, USB Configuration, and the UEFI Update Utility. Clicking into the CPU Configuration screen, you are going to be able to see your current processor speed, as well as the Ratio Status and the Ratio Limit. You can change the Intel Hyper Threading Technology, Active Processor Cores, Hardware Prefetcher, and Adjacent Cache Line Prefetch, as well as all the Intel Thermal/Power savings settings here. In the North Bridge Configuration screen you are going to be able to set all the North Bridge Configurations that you may want to adjust. This is also where you are going to be able to enable the onboard graphics and set which graphics adapter is the primary. In the South Bridge Configuration screen, you are going to be able to adjust the Onboard Audio, 1394, and LAN settings, as well as set the Restore on AC/Power Loss settings.
The Storage Configuration screen is where you are going to be able to set up all of your SATA settings. This includes not only your hard drives, but your optical devices as well. You can enable or disable Hard Disk SMART features on this screen as well. Under the Super IO configuration screen you are able to adjust your Floppy controller, Serial Port, and the Infrared Port. Under the ACPI screen, you are able to make adjustments to the USB connectors as well as the PS/2 connector and other settings. The USB Configuration is where you are going to be able to turn on and off the USB 2.0 and 3.0 controllers, as well as enable or disable the Legacy USB and USB 3.0 support.
The H/W Monitor screen is where you are going to be able to view the current status of your system, such as your CPU temperature, Motherboard temperature, Fan speeds, Vcore, and 12.0, 5.0 and 3.3v lines from your PSU. You are also able to enable the Over Temperature Protection here, as well as change your PWM Fan settings. When you go to the Boot screen, you are able to make changes to your Boot Option Priorities, as well as your Setup Prompt Timeout and Boot Failure Guard. This is also the screen you are going to use to enable to Full Screen Logo if you want or you can disable it. Clicking the Hard Drives BBS Priorities link will take you to a sub-menu where you can change the boot options of your hard drives alone, while the CD/DVD ROm Drive BBS Priories link will take you to a sub-menu where you can change your optical drive boot order.
The final two screens left in the ASRock uEFI BIOS are the Security Screen and the Exit screen. When you make your way to the Security screen, you are able to set a Supervisor or User password. On the Exit screen, you are going to be able to save all of your settings you have made and exit, discard your changes and exit, just discard your changes, or Load UEFI Defaults. The Launch EFI Shell from filesystem device option is going to attempt to Launch EFI Shell application (Shell64.efi) from one of the available filesystem devices.
