you fail to plug this connector.

1.7 System memory

1.7.1 Overview

This motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Modules
(DIMM) sockets. A DDR3 module has the same physical dimensions as a DDR2 DIMM but
is notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are

developed for better performance with less power consumption. The gure illustrates the

location of the DDR3 DIMM sockets:

ASUS M5A88-M EVO 1-11

1.7.2 Memory congurations

You may install 512MB, 1GB, 2GB, and 4GB unbuffered ECC and non-ECC DDR3 DIMMs
into the DIMM sockets.

• 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.

• We recommend that you install the memory modules from the blue slots for better
overclocking capability.

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

• Due to CPU specication, AMD

®

100 and 200 series CPUs support up to DDR3

1066MHz. With ASUS design, this motherboard can support up to DDR3 1333MHz.

• When overclocking, some AMD CPU models may not support DDR3 1600 MHz or

higher frequency DIMMs.

• 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:

- Install a maximum of 3GB system memory if you are using a 32-bit Windows

®

OS.

- Use a 64-bit Windows® OS if you want to install 4GB or more memory on the
motherboard.

• This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less.

M5A88-M EVO Motherboard Qualied Vendors Lists (QVL)

DDR3-2000(O.C.)MHz capability for AMD AM3 socket

• 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. To operate at the vendor-marked or at a
higher frequency, refer to section 2.4 Ai Tweaker menu for manual memory frequency
adjustment.

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

memory load (2 DIMMs) or overclocking condition.

1.8 Expansion slots

In the future, you may need to install expansion cards. The following sub-sections describe
the slots and the expansion cards that they support.

Unplug the power cord before adding or removing expansion cards. Failure to do so may
cause you physical injury and damage motherboard components.

1.8.1 Installing an expansion card

To install an expansion card:

1. Before installing the expansion card, read the documentation that came with it and
make the necessary hardware settings for the card.

2. Remove the system unit cover (if your motherboard is already installed in a chassis).

3. Remove the bracket opposite the slot that you intend to use. Keep the screw for later
use.

4. Align the card connector with the slot and press rmly until the card is completely

seated on the slot.

5. Secure the card to the chassis with the screw you removed earlier.

6. Replace the system cover.

When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that

the cards do not need IRQ assignments. Otherwise, conicts will arise between the two PCI

groups, making the system unstable and the card inoperable.

1.8.3 PCI slot

The PCI slot supports cards such as a LAN card, SCSI card, USB card, and other cards that

comply with PCI specications.

1.8.2 Conguring an expansion card

After installing the expansion card, congure it by adjusting the software settings.

1. Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for
information on BIOS setup.

2. Assign an IRQ to the card.

3. Install the software drivers for the expansion card.

1.8.4 PCI Express x1 slots

This motherboard supports PCI Express x1 network cards, SCSI cards, and other cards that

comply with the PCI Express specications.

1.8.5 PCI Express x16 slot

This motherboard supports a PCI Express x16 graphics slot that complys with the PCI

Express specications.

Chapter 1: Product introduction1-22

1.9 Jumpers

Clear RTC RAM (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 reenter

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 clearing the CMOS, 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 CPU Parameter Recall (C.P.R) feature. Shut
down and reboot the system so the BIOS can automatically reset parameter settings to
default values.

1.12 Onboard switches

Onboard switches allow you to ne-tune performance when working on a bare or open-case

system. This is ideal for overclockers and gamers who continually change settings to
enhance system performance.

1. MemOK! switch

Installing DIMMs that are incompatible with the motherboard may cause system boot failure,
and the DRAM_LED near the MemOK! switch lights continuously. Press and hold the
MemOK! switch until the DRAM_LED starts blinking to begin automatic memory compatibility
tuning for successful boot.

• Refer to section 1.11 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! switch 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 fail to boot due to BIOS overclocking, press the MemOK! switch to boot
and load 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.

• The TPU LED (02LED2) near the TPU switch lights when the switch setting is turned to

Enable.

• If you clear the CMOS or load the BIOS setup defaults, the related overclocking items in
the BIOS menu follow the current setting of the TPU switch.

• If you change the switch setting to

Enable under the OS environment, the TPU function

will be activated after the next system bootup.

• You may use the TurboV and Auto Tuning features in the TurboV EVO application, adjust
the BIOS settings, or enable the TPU function at the same time. However, the system will
use the last setting you have made.
