2.4 System memory

2.4.1 Overview

The motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory

Modules (DIMM) slots.

A DDR3 module is notched differently from a DDR or DDR2 module. DO NOT install a DDR or DDR2 memory module to the DDR3 slot.

Page 30

Chapter 2: Hardware setup2-12

2.4.2 Memorycongurations

You may install 1GB, 2GB, 4GB, 8GB unbuffered ECC or non-ECC DDR3 DIMMs

into the DIMM sockets depending on the installed CPU.

• 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 conguration. Any excess memory from the higher-sized channel is then

mapped for single-channel operation.

• According to Intel CPU spec, DIMM voltage below 1.65V is recommended

to protect the CPU.

• The max. 32GB memory capacity can be supported with DIMMs of 8GB (orThe max. 32GB memory capacity can be supported with DIMMs of 8GB (or

above).

• Always install DIMMs with the same CAS latency. For optimum compatibility, we recommend that you obtain memory modules from the same vendor.

• 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:

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

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

motherboard. For more details, refer to the Microsoft® support site at

http://support.microsoft.com/kb/929605/en-us.

• This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less (Memory chip capacity counts in Megabit, 8 Megabit/Mb = 1 Megabyte/MB).

For system stability, use a more efcient memory cooling system to support a

full memory load (4 DIMMs) or overclocking condition.

P8CWSMotherboardQualiedVendorsLists(QVL)

• ASUS exclusively provides hyper DIMM support function.

• Hyper DIMM support is subject to the physical characteristics of individual

CPUs. Load the X.M.P. settings in the BIOS for the hyper DIMM support.

• Visit the ASUS website for the latest QVL.

2.4.3 Installing a DIMM

A DIMM is keyed with a notch so that it ts in only one direction. DO NOT force

a DIMM into a socket in the wrong direction to avoid damaging the DIMM.

• Ensure to unplug the power supply before adding or removing DIMMs or other system components. Failure to do so may cause severe damage to both the motherboard and the components.

• Always insert the DIMM into the socket VERTICALLY to prevent DIMM

notch damage.

Page 48

Chapter 3: Motherboard information3-6

3. 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 (Qualied 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.

Chapter 3: Motherboard information3-10

3.4 Jumpers

1. Clear RTC RAM (3-pin CLRTC)

This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which include system setup information such as system passwords.

To erase the RTC RAM

1. Turn OFF the computer and unplug the power cord.

2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5–10 seconds, then move the cap back to pins 1-2.

3. Plug the power cord and turn ON the computer.

4. Hold down the <Del> key during the boot process and enter BIOS setup to re-

enter data.

Except when clearing the RTC RAM, never remove the cap on CLRTC jumper

default position. Removing the cap will cause system boot failure!

• If the steps above do not help, remove the onboard battery and move the jumper again to clear the CMOS RTC RAM data. After the CMOS clearance, reinstall the battery.

• You do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the C.P.R. (CPU

Parameter Recall) feature. Shut down and reboot the system so the BIOS

can automatically reset parameter settings to default values.

• Due to the chipset behavior, AC power off is required to enable C.P.R. function. You must turn off and on the power supply or unplug and plug the power cord before rebooting the system.

Page 53

3-11ASUS ESC500 G2

• If you use a 4-pin fan but set the jumper to pin 1-2, the fan you installed

may not work.

• If you use a 3-pin fan but set the jumper for a 4-pin fan, the fan control will

not work and the fan you installed will always run at full speed.

2. Chassis Fan control setting (3-pin CHAFAN_SEL)

These jumpers allow you to switch for fan pin selection. The CHAFAN_SEL jumper is for the front fans and rear fans control. Set to pins 1–2 when using 3-pin fans or pins 2–3 when using 4-pin fans.

4.1 Knowing BIOS

The new ASUS UEFI BIOS is a Unied Extensible Interface that complies

with UEFI architecture, offering a user-friendly interface that goes beyond

the traditional keyboard-only BIOS controls to enable a more exible and convenient mouse input. Users can easily navigate the new UEFI BIOS with the same smoothness as their operating system. The term “BIOS” in this user manual refers to “UEFI BIOS” unless otherwise specied.

BIOS (Basic Input and Output System) stores system hardware settings such as storage device conguration, overclocking settings, advanced power management, and boot device conguration that are needed for system startup in the motherboard CMOS. In normal circumstances, the default BIOS settings apply

to most conditions to ensure optimum performance. We recommend that you not change the default BIOS settings except in the following circumstances:

4.2 BIOS setup program

A BIOS setup program is provided for BIOS item modication. When you start up

the computer, the system provides you with the opportunity to run this program. Press <Del> during the Power-On Self-Test (POST) to enter the Setup utility. Otherwise, POST continues with its test routines.

If you wish to enter Setup after POST, press <Ctrl> + <Alt> + <Delete>, or press the reset button on the system chassis to restart the system. You can also turn the system off and then turn it back on to restart the system. Do this last option only if

the rst two failed.

• The BIOS setup screens shown in this section are for reference purposes

only, and may not exactly match what you see on your screen.

• Ensure that a USB mouse is connected to your motherboard if you want to use the mouse to control the BIOS setup program.

• If the system becomes unstable after changing any BIOS setting, load

the default settings to ensure system compatibility and stability. Select the

Load Optimized Defaults item under the Exit menu. See section 4.9 Exit Menu for details.

• If the system fails to boot after changing any BIOS setting, try to clear the

CMOS and reset the motherboard to the default value. See sectionSee section 2.2.5 Onboard switches for information on how to erase the RTC RAM.

• The BIOS setup program does not support the bluetooth devices.

The BIOS setup program is designed to make it as easy to use as possible. Being

a menu-driven program, it lets you scroll through the various submenus and select

from the available options using a keyboard or a USB mouse.

The BIOS setup program can be used under two modes: EZ Mode and Advanced

Mode. You can change modes from the Exit menu or from the Exit/Advanced Mode button in the EZ Mode/Advanced Mode screen.
