System memory
2.4.1
Overview
The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory Modules
(DIMM) sockets.
A DDR2 module has the same physical dimensions as a DDR DIMM but has a 240-pin
footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched differently to
prevent installation on a DDR DIMM socket.
The figure illustrates the location of the DDR2 DIMM sockets:

Chapter 2: Hardware information
2.4.2
Memory configurations
•
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 CPU limitation, DDR2 1066 MHz is supported by AM3/AM2+ CPU for one
DIMM per channel only. For system stability, when four DIMMs are installed, all DIMMs
run at DDR2 800 MHz as the default setting.
•
We recommend that you install the memory modules from the yellow slots for better
overclocking capability.
•
Always install DIMMs with the same CAS latency. For optimum compatibility, it is
recommended 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.
•
This motherboard does not support DIMMs made up of 256 megabit (Mb) 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, see section 3.6 Advanced menu for manual memory frequency
adjustment.
•
For system stability, use a more efficient memory cooling system to support a full
memory load (4 DIMMs) or overclocking condition.
ASUS M4A78-E
Chapter 2
You may install 512MB, 1GB, 2GB and 4GB unbuffered ECC and non‑ECC DDR2 DIMMs
into the DIMM sockets.

Expansion slots
In the future, you may need to install expansion cards. The following subsections describe the
slots and the expansion cards that they support.
Ensure to unplug the power cord before adding or removing expansion cards. Failure to do
so may cause you physical injury and damage motherboard components.
2.5.1
Installing an expansion card
To install an expansion card:
2.
3.
4.
5.
6.
Before installing the expansion card, read the documentation that came with it and
make the necessary hardware settings for the card.
Remove the system unit cover (if your motherboard is already installed in a chassis).
Remove the bracket opposite the slot that you intend to use. Keep the screw for later
use.
Chapter 2
1.
Align the card connector with the slot and press firmly until the card is completely
seated on the slot.
Secure the card to the chassis with the screw you removed earlier.
Replace the system cover.
2.5.2
Configuring an expansion card
After installing the expansion card, configure it by adjusting the software settings.
1.
2.
3.
Turn on the system and change the necessary BIOS settings, if any. See Chapter 3 for
information on BIOS setup.
Assign an IRQ to the card. Refer to the tables on the next page.
Install the software drivers for the expansion card.
When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that
the cards do not need IRQ assignments. Otherwise, conflicts will arise between the two PCI
groups, making the system unstable and the card inoperable. Refer to the table on the next
page for details.

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.
Chapter 2
1.
Jumpers
To erase the RTC RAM
1.
Turn OFF the computer and unplug the power cord.
3.
Plug the power cord and turn ON the computer.
2.
4.
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.
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.

Pins 2-3 (Default)
0.80V – 1.70V
Pins 1-2 (OV Enabled)
up to 1.90V
•
Before you change the jumper setting for extra-high overvoltage ability, use the BIOS
items introduced in 3.5 Ai Tweaker menu first to adjust the desired CPU performance.
Ensure that your system functions well under the highest BIOS voltage setting before
you change the setting of this jumper.
•
Refer to 3.5 Ai Tweaker menu for more information about the CPU overvoltage
setting.
•
DO NOT set the OV_CPU jumper to pins 1-2 when you install a new CPU and have
not booted for the first time. Doing so may cause the system to halt. For system failure
due to the wrong setting of the OV_CPU jumper, shut down the computer and move
the cap back to pins 2-3.
•
The system may need a better cooling system (for example, a water-cooling system)
to work stably under high voltage settings.

RAID configurations
The motherboard comes with the AMD SB750 chipset that allows you to configure Serial ATA
hard disk drives as RAID sets. The motherboard supports the following RAID configurations:
RAID 0, RAID 1, RAID 5, and RAID 10.
4.4.1
RAID definitions
RAID 0 (Data striping) optimizes two identical hard disk drives to read and write data in
parallel, interleaved stacks. Two hard disks perform the same work as a single drive but at a
sustained data transfer rate, double that of a single disk alone, thus improving data access
and storage. Use of two new identical hard disk drives is required for this setup.
RAID 1 (Data mirroring) copies and maintains an identical image of data from one drive to
a second drive. If one drive fails, the disk array management software directs all applications
to the surviving drive as it contains a complete copy of the data in the other drive. This RAID
configuration provides data protection and increases fault tolerance to the entire system. Use
two new drives or use an existing drive and a new drive for this setup. The new drive must be
of the same size or larger than the existing drive.
RAID 5 stripes both data and parity information across three or more hard disk drives. Among
the advantages of RAID 5 configuration include better HDD performance, fault tolerance, and
higher storage capacity. The RAID 5 configuration is best suited for transaction processing,
relational database applications, enterprise resource planning, and other business systems.
Use a minimum of three identical hard disk drives for this setup.
RAID 10 is data striping and data mirroring combined without parity (redundancy data) having
to be calculated and written. With the RAID 0+1 configuration you get all the benefits of both
RAID 0 and RAID 1 configurations. Use four new hard disk drives or use an existing drive
and three new drives for this setup.
Chapter 4
For Windows XP, If you want to boot the system from a hard disk drive included in a RAID
set, first copy the RAID driver from the support DVD to a floppy disk before you install an
operating system to a selected hard disk drive. Refer to section 4.5 Creating a RAID driver
disk for details.
ASUS M4A78-E
4-13
4.4.2
Installing Serial ATA hard disks
The motherboard supports Serial ATA hard disk drives. For optimal performance, install
identical drives of the same model and capacity when creating a disk array.
To install the SATA hard disks for a RAID configuration:
1.
Install the SATA hard disks into the drive bays.
3.
Connect a SATA power cable to the power connector on each drive.
2.
Connect the SATA signal cables.
4.4.3
Setting the RAID item in BIOS
You must enable the RAID function in the BIOS Setup before creating RAID set(s) using
SATA HDDs. To do this:
1.
Enter the BIOS Setup during POST.
3.
Set the OnChip SATA Type item to [RAID].
2.
