ASUS Crosshair II Formula 2-1
2.1 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.
• Use a grounded wrist strap or touch a safely grounded object or a metal
object, such as the power supply case, before handling components 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, ensure that the ATX power
supply is switched off or the power cord is detached from the power
supply. Failure to do so may cause severe damage to the motherboard,
peripherals, and/or components.
Onboard LEDs

memory, southbridge, and bridge (PCIe). You may adjust the voltages in BIOS.
There are also an LED for hard disk drive activity and an onboard switch for power
status. For more information about voltage adjustment, refer to 4.3 Extreme
