Refer to section
1.1.7 Onboard LEDs
for the exact location of the Q LED(DRAM).
The DRAM LED also lights up when the DIMM is not properly installed. Turn off the
system and reinstall the DIMM before using the MemOK! 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 whole tuning
process, the DRAM LED lights continuously. Replace the DIMMs with ones
recommended in the Memory QVL (Quali ed Vendors Lists) 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
www.asus.com after using the MemOK! function.
3. MemOK! button (MemOK!)
Installing DIMMs that are not compatible with the motherboard may cause system boot
failure, and the DRAM LED lights continuously. Press and hold the MemOK! button
until the DRAM LED starts blinking to begin automatic memory compatibility tuning for
successful boot.
