3. MemOK! button (MemOK!) Installing DIMMs that are not compatible with the motherboard may cause system boot failure. One indicator is the DRAM_LED lighting continuously. Press and hold the MemOKI button to initiate the memory compatibility tuning process that can help lead to a successful boot. NOE MemOK! via IzQ , Eun MOW% V EXITIEWIZC Da ito ,I nami:o=olia=mrarommo anatook, RAMPAGE V EXTREME MemOK! button • Refer to the Onboard LEDs section for the exact location of the DRAM_LED. • The DRAM_LED also lights up when the DIMM is not properly installed. Turn off the system and reinstall the DIMM before using the MemOKI function. • The MemOK! button does not function under Windows® OS environment. • 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. The blinking speed of the DRAM_LED increases, indicating different test processes. • 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 tuning process is completed, the DRAM_LED lights continuously. Replace the DIMMs with ones recommended in the Memory QVL (Qualified Vendors Lists) in this user manual or 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 to remind you that the BIOS has been restored to its default settings. • We recommend that you download and update to the latest BIOS version from www.asus.com after using the MemOK! function. 1-22 Chapter 1: Product introduction

To
stop
memory
tuning,
turn
off
the
computer
and
unplug
the
power
cord
for
about
5-10
seconds.
•
