1.7 System memory
1.7.1 Overview
The motherboard comes with two Double Data Rate 3 (DDR3) Dual Inline Memory Modules
(DIMM) sockets. The gure illustrates the location of the DDR3 DIMM sockets:
Channel Sockets
Channel A DIMM_A1
Channel B DIMM_B1
1-12 Chapter 1: Product introduction
1.7.2 Memory congurations
You may install 512MB, 1GB, 2GB, and 4GB unbuffered non-ECC DDR3 DIMMs into the
DIMM sockets.
• 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
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 memory on
the motherboard.
• This motherboard does not support DIMMs made up of 256 megabits (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.
• For system stability, use a more efcient cooling system to support a full memory load (2
DIMMs) or overclocking conditions.

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.
1.8.2 Conguring an expansion card
After installing the expansion card, congure 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.
When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that
the cards do not need IRQ assignments. Otherwise, conicts will arise between the two PCI
groups, making the system unstable and the card inoperable.
1.8.3 PCI slots
The PCI slots support cards such as a LAN card, SCSI card, USB card, and other cards that
comply with PCI specications.
1.8.4 PCI Express x1 slot
This motherboard supports PCI Express x1 network cards, SCSI cards, and other cards that
comply with the PCI Express specications.
1.8.5 PCI Express x16 slot
This motherboard supports a PCI Express x16 graphics card that complies with the PCI
Express specications.

1.9 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
data.
<Del> key during the boot process and enter BIOS setup to re-enter
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, then the BIOS automatically resets parameter settings to
default values.
