1.1Motherboard overview

1.1.1Before 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.

•Before handling components, use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, 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, or components.

•You may install varying memory sizes in Channel A and Channel B. The system

maps the total size of the lower-sized channel for the dual-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation.

•Due to the memory address limitation on 32-bit Windows OS, when you install 4GB or more memory on the motherboard, the actual usable memory for the OS can be about 3GB or less. For effective use of memory, we recommend that you do any of the following:

a)Use a maximum of 3GB system memory if you are using a 32-bit Windows OS.

b)Install a 64-bit Windows OS when you want to install 4GB or more on the motherboard.

c)For more details, refer to the Microsoft® support site at http://support.microsoft.com/kb/929605/en-us.

•The design of the DIMM fan may vary. Ensure that the DIMM fan fits to the motherboard.

•The default memory operation frequency is dependent on its Serial Presence Detect (SPD), which is the standard way of accessing information from a memory module. Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value.

•For system stability, use a more efficient memory cooling system to support a full memory load (4 DIMMs) or overclocking condition.

•Memory modules with memory frequency higher than 2133MHz and their corresponding timing or the loaded XMP profile is not the JEDEC memory standard. The stability and compatibility of the memory modules depend on the CPU’s capabilities and other installed devices.

•Always install the DIMMS with the same CAS latency. For an optimum compatibility, we recommend that you install memory modules of the same version or data code (D/C) from the same vendor. Check with the vendor to get the correct memory modules.

•ASUS exclusively provides hyper DIMM support function.

•Hyper DIMM support is subject to the physical characteristics of individual CPUs. Load the X.M.P. or D.O.C.P. settings in the BIOS for the hyper DIMM support.

•Visit the ASUS website for the latest QVL.

Power-on button (START)

Chapter

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

up the system. The LED near 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.

2.RESET button (RESET)

Press the reset button to reboot the system.

	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
1 Chapter	until the DRAM_LED starts blinking to begin automatic memory compatibility tuning for
	successful boot.

•Refer to section 1.1.7 Onboard LEDs 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 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 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.
