Onboard buttons and switches

Onboard buttons allow you to fine-tune performance when working on a bare or open-

case system. This is ideal for overclockers and gamers who continually change settings to

enhance system performance.

Power-on button (START)

The motherboard comes with a power-on button that allows you to power

up or wake up the system. The button also lights up when the system is

plugged to a power source indicating that you should shut down the system

and unplug the power cable before removing or installing any motherboard

component.

RESET button (RESET)

Press the reset button to reboot the system.

MemOK! button (MemOK!)

Installing DIMMs that are not compatible with the motherboard may

cause system boot failure. Press the MemOK! button until the memory

compatibility tuning for successful boot.

•

Turn off the system and reinstall the DIMM before using the MemOK! function.

•

The MemOK! button does not function under Windows

•

During the tuning process, the system loads and tests failsafe memory settings. It

takes about 30 seconds for the system to test one set of failsafe settings. If the test

fails, the system reboots and test the next set of failsafe settings.

•

Due to memory tuning requirement, the system automatically reboots when each

timing set is tested. If the installed DIMMs still fail to boot after the whole tuning

process, replace the DIMMs with ones recommended in the Memory QVL (Qualified

Vendors Lists) in this user manual or on the ASUS website at www.asus.com.

•

If you turn off the computer and replace DIMMs during the tuning process, the system

continues memory tuning after turning on the computer. To stop memory tuning, turn

off the computer and unplug the power cord for about 5–10 seconds.

•

If your system fails to boot up due to BIOS overclocking, press the MemOK! button

to boot and load the BIOS default settings. A message will appear during POST

reminding you that the BIOS has been restored to its default settings.

•

We recommend that you download and update to the latest BIOS version from the

ASUS website at www.asus.com after using the MemOK! function.
