1-3Chapter 1: Product introduction
C.P.R. (CPU Parameter Recall)
The BIOS C.P.R. feature automatically restores the CPU default settings
when the system hangs due to overclocking failure. C.P.R. eliminates the
need to open the system chassis and clear the RTC data. Simply shut
down and reboot the system, and the BIOS automatically restores the
CPU parameters to their default settings.
ErP ready
The motherboard is European Union´s Energy-related Products (ErP)
ready, and ErP requires products to meet certain energy efciency
requirements in regards to energy consumptions. This is in line with
ASUS vision of creating environment-friendly and energy-efcient
products through product design and innovation to reduce carbon
footprint of the product and thus mitigate environmental impacts.
1.4 Before 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.
ASUS E45M1-M PRO1-4
E45M1-M PRO
1.5 Motherboard overview
Before you install the motherboard, study the conguration of your chassis to ensure that the
motherboard ts into it.
Ensure that you unplug the power cord before installing or removing the motherboard.
Failure to do so can cause you physical injury and damage motherboard components.
1.5.1 Placement direction
When installing the motherboard, ensure that you place it into the chassis in the correct
orientation. The edge with external ports goes to the rear part of the chassis as indicated in
the image below.
1.5.2 Screw holes
Place six screws into the holes indicated by circles to secure the motherboard to the chassis.
Do not overtighten the screws! Doing so can damage the motherboard.
Place this side towards
the rear of the chassis

The motherboard comes with an integrated AMD® Dual-Core Processor E-450 with AMD®
Radeon™ HD 6320 Discrete-Class graphics and a specially designed CPU heatsink.
1.6.1 Installing the CPU fan
To install the CPU fan:
1. Place the CPU fan on top of the CPU
heatsink.
2. Secure the fan on the heatsink with
the four screws.
3. Connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN.
• Do not forget to connect the CPU fan connector! Hardware monitoring errors can occur
if you fail to plug this connector.
• Ensure that the CPU fan is installed properly when overclocking.

1.6.2 Uninstalling the CPU fan
To uninstall the CPU fan:
1. Disconnect the CPU fan cable from the
connector on the motherboard.
2. Remove the four screws from the CPU fan.
3. Remove the CPU fan from the CPU
heatsink.
1.7 System memory
1.7.1 Overview
The motherboard comes with two 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:

1.7.2 Memory congurations
You may install 1GB, 2GB, and 4GB unbuffered non-ECC DDR3 DIMMs into the DIMM
sockets.
• We recommend that you install the memory modules from the blue slots for better
overclocking capability.
• 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
- Install a 64-bit Windows® OS when you want to install 4GB or more on the
motherboard.
• This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less.
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.
