C.P.R. (CPU Parameter Recall)

The BIOS C.P.R. feature automatically restores the CPU default settings

when the system hangs due to overclocking failure. C.P.R. eliminates the

need to open the system chassis and clear the RTC data. Simply shut

down and reboot the system, and the BIOS automatically restores the

CPU parameters to their default settings.

Before you proceed

Take note of the following precautions before you install motherboard components or change

any motherboard settings.

•

Unplug the power cord from the wall socket before touching any component.

•

Before handling components, use a grounded wrist strap or touch a safely grounded

object or a metal object, such as the power supply case, to avoid damaging them due to

static electricity.

•

Hold components by the edges to avoid touching the ICs on them.

•

Whenever you uninstall any component, place it on a grounded antistatic pad or in the

bag that came with the component.

•

Before you install or remove any component, switch off the ATX power supply and

detach its power cord. Failure to do so may cause severe damage to the motherboard,

peripherals, or components.

Onboard LED

The motherboard comes with a standby power LED that lights up to indicate that the system

is ON, in sleep mode, or in soft-off mode. This is a reminder that you should shut down

the system and unplug the power cable before removing or plugging in any motherboard

component. The illustration below shows the location of the onboard LED.
