The new ASUS UEFI BIOS is a Unied Extensible Interface that complies with UEFI
architecture, offering a user-friendly interface that goes beyond the traditional keyboard-
only BIOS controls to enable a more exible and convenient mouse input. You can easily
navigate the new UEFI BIOS with the same smoothness as your operating system. The
term “BIOS” in this user manual refers to “UEFI BIOS” unless otherwise specied.
BIOS (Basic Input and Output System) stores system hardware settings such as storage
device conguration, overclocking settings, advanced power management, and boot
device conguration that are needed for system startup in the motherboard CMOS. In
normal circumstances, the default BIOS settings apply to most conditions to ensure
optimal performance. DO NOT change the default BIOS settings except in the following
circumstances:
• An error message appears on the screen during the system bootup and requests you
to run the BIOS Setup.
• You have installed a new system component that requires further BIOS settings or
update.
Inappropriate BIOS settings may result to instability or boot failure. We strongly
recommend that you change the BIOS settings only with the help of a trained service
personnel.
When downloading or updating the BIOS le, rename it as X99D2.CAP for this
motherboard.
BIOS Setup
1.1 Knowing BIOS

• If the system becomes unstable after changing any BIOS setting, load the default
settings to ensure system compatibility and stability. Select the Load Optimized
Defaults item under the Exit menu or press hotkey <F5>. See section 1.10 Exit Menu
for details.
• If the system fails to boot after changing any BIOS setting, try to clear the CMOS and
reset the motherboard to the default value. See section 1.1.6 Onboard buttons and
switches in your user manual for information on how to erase the RTC RAM via the
Clear CMOS button.
• The BIOS setup program does not support the Bluetooth devices.
Please visit ASUS website for the detailed BIOS content manual.

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
This item allows you to set the initial BCLK (base clock) frequency to start overclocking
to the assigned BCLK frequency. Use the <+> or <-> to adjust the value. The initial
BCLK frequency cannot be less than 80.0 MHz.
