Simply press the MemOK button until the DRAM_ LED starts blinking to patch memory compatibility issues and ensure the system's successful bootup. • Refer to section 3.3 Onboard LEDs for the exact location of the DRAM_ LED. • The DRAM_LED also lights 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 (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. 3-6 Chapter 3: Motherboard information

MemOK! button
When you install DIMMs that are not compatible with the motherboard, this
may cause the system boot failure, and the DRAM_LED near the MemOK
switch lights continuously. Simply press the MemOK button until the DRAM_
LED starts blinking to patch memory compatibility issues and ensure the
system’s successful bootup.
•
Refer to section
3.3 Onboard LEDs
for the exact location of the DRAM_
LED.
•
The DRAM_LED also lights 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 (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.
