1.6.2 Installing the heatsink and fan
The AMD Athlon™ 64 / Sempron™ / Athlon™ FX / Athlon™ 64 X2 / AM2+ /
Phenom™ FX / Phenom™ processor requires a specially designed heatsink and
fan assembly to ensure optimum thermal condition and performance.
Ensure that you use only qualied heatsink and fan assembly.
Follow these steps to install the CPU heatsink and fan.
1. Place the heatsink on top of the installed CPU, ensuring that the heatsink ts
properly on the retention module base.
• The retention module base is already installed on the motherboard
upon purchase.
• You do not have to remove the retention module base when
installing the CPU or installing other motherboard components.
• If you purchased a separate CPU heatsink and fan assembly, make
sure that a Thermal Interface Material is properly applied to the CPU
heatsink or CPU before you install the heatsink and fan assembly.

1.7 System memory
1.7.1 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 gure illustrates the location of the DDR2 DIMM sockets:
Channel Sockets
Channel A DIMM_A1 and DIMM_A2
Channel B DIMM_B1 and DIMM_B2
1.7.2 Memory congurations
You may install 256 MB, 512 MB, 1 GB, and 2 GB unbuffered ECC / non-ECC
DDR2 DIMMs into the DIMM sockets.

• When using only one memory module, start installing the DDR2 DIMM from
slot DIMM_A1 or DIMM_B1 for better overclocking capability.
• For dual-channel conguration (2), you may:
- install identical DIMMs in all four sockets OR
- install identical DIMM pair in DIMM_A1 and DIMM_B1 (yellow sockets)
and another identical DIMM pair in DIMM_A2 and DIMM_B2 (black
sockets)
• Due to the chipset’s limitation, the 1066 MHz memory modules run at 1066
MHz only when:
- two 1066 MHz memory modules installed in the same colored-slots
(either in the yellow slots or black slots); and
- one 1066 MHz memory module installed in any of the slots.
In other cases, the 1066 MHz memory modules can only run at
800 MHz.
• Always use identical DDR2 DIMM pairs for dual channel mode. For
optimum compatibility, we recommend that you obtain memory modules
from the same vendor.
• If you are using a Windows 32-bit version operating system (e.g. 32-bit
Windows, 32-bit Vista) without the Physical Address Extension (PAE)
support, the system will allocate a certain amount of memory space for
system devices.
• We recommend that you install only a maximum of 3GB system memory
when using a Windows 32-bit version operating system without the PAE.
The excess over 3GB of installed memory will not cause any problem;
however, the system can not use this excess memory space and the
system will display less than the total size of physical memory installed.
The motherboard can support 8 GB physical memory on the operating system
listed below. You may install a maximum of 2 GB DIMMs on each slot.

1.9 Jumpers
1. 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. Remove the onboard battery.
3. 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.
4. Reinstall the battery.
5. Plug the power cord and turn ON the computer.
6. 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!
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.

Set these jumpers to +5V to wake up the computer from S1 sleep mode
(CPU stopped, DRAM refreshed, system running in low power mode) using
the connected USB devices. Set to +5VSB to wake up from S3 and S4 sleep
modes.
The USBPW1-4 jumpers are for the rear USB ports. The USBPW5-8 and
USBPW910 jumpers are for the internal USB connectors that you can
connect to additional USB ports.
• The USB device wake-up feature requires a power supply that can
provide 500mA on the +5VSB lead for each USB port. Otherwise,
the system will not power up.
• The total current consumed must NOT exceed the power supply
capability (+5VSB) whether under normal condition or in sleep mode.
