Chapter 1: Product introduction
•
•
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 configuration (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.

power supply unit (PSU) with a minimum of 300 W power rating. This PSU
type has 24-pin and 4-pin power plugs.
If you intend to use a PSU with 20-pin and 4-pin power plugs, ensure that
the 20-pin power plug can provide at least 15 A on +12 V and that the PSU
has a minimum power rating of 300 W. The system may become unstable
or may not boot up if the power is inadequate.
•
•
Do not forget to connect the 4-pin ATX +12 V power plug. Otherwise, the
system will not boot up.
We recommend that you use a PSU with higher power output when
configuring a system with more power-consuming devices. The system
may become unstable or may not boot up if the power is inadequate.
•
If you are uncertain about the minimum power supply requirement for your
system, refer to the Recommended Power Supply Wattage Calculator
at http://support.asus.com/PowerSupplyCalculator/PSCalculator.

BIOS setup program
This motherboard supports a programmable Serial Peripheral Interface (SPI) chip
that you can update using the provided utility described in section “2.1 Managing
and updating your BIOS”.
Use the BIOS Setup program when you are installing a motherboard, reconfiguring
your system, or prompted to “Run Setup”. This section explains how to configure
your system using this utility.
Even if you are not prompted to use the Setup program, you can change the
configuration of your computer in the future. For example, you can enable the
security password feature or change the power management settings. This
requires you to reconfigure your system using the BIOS Setup program so that the
computer can recognize these changes and record them in the CMOS RAM of the
SPI chip.
The SPI chip on the motherboard stores the Setup utility. When you start up the
computer, the system provides you with the opportunity to run this program. Press
<Del> during the Power-On Self-Test (POST) to enter the Setup utility. Otherwise,
POST continues with its test routines.
If you wish to enter Setup after POST, reboot the system by doing any of the
following procedures:
• Restart using the OS standard shut-down procedure.
• Press <Ctrl>+<Alt>+<Del> simultaneously.
• Press the reset button on the system chassis.
• Press the power button to turn the system off then back on.
Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys to
force reset from a running operating system can cause damage to your data
or system. We recommend to always shut-down the system properly from the
operating system.
The Setup program is designed to make it as easy to use as possible. Being a
menu-driven program, it lets you scroll through the various sub-menus and make
your selections from the available options using the navigation keys.
•
The default BIOS settings for this motherboard apply for most conditions
to ensure optimum performance. If the system becomes unstable after
changing any BIOS settings, load the default settings to ensure system
compatibility and stability. Select the Load Default Settings item under the
Exit Menu. See section “2.8 Exit Menu.”

This chapter tells how to use the Hybrid
SLI® feature.
NVIDIA® technology

support
4.1
NVIDIA® Hybrid SLI® Technology
The motherboard supports the NVIDIA® Hybrid SLI® technology that includes two
primary features: GeForce® Boost and HybridPower™. GeForce® Boost enhances
the performance of NVIDIA discrete Graphics Process Units (dGPU) when they
work with the onboard motherboard GPU (mGPU). HybridPower™ unleashes the
graphics performance of the dGPU and enables low-power operation when the
performance of the dGPU is not needed. You can switch from the dGPU(s) to the
mGPU for a quiet, power-saving computer environment.
•
•
Hybrid SLI technology is supported by Windows® Vista™ only.
GeForce Boost supports up to two displays simultaneously (both connected
to either the mGPU or the dGPU).
•
When two or more displays are connected to both the mGPU and the
dGPU, the Hybrid SLI mode is disabled and the multi-display mode is
enabled. In the multi-display mode, up to four displays could be connected
(up to two displays driven by the mGPU and up to two displays by the
dGPU).
•
•
HybridPower requires displays to be connected to the mGPU. HybridPower
cannot be enabled when displays are driven through the dGPU.
HybridPower and GeForce Boost are supported by certain set of dGPUs.
Go to www.nvidia.com/hybridsli to learn the supported GPUs.
4.1.1
System requirements
Before using Hybrid SLI, ensure if your system meets the following requirements:
For best GeForce Boost performance
•
•
•
•
AMD Phenom 9600 CPU (operating at 1800Mhz or higher)
2 x 1024MB of DDR2-800 DRAM
Discrete GPU recommended for GeForce Boost
At least 256MB of Frame Buffer carve out for the motherboard GPU
For best HybridPower benefits
•
•
•
•
AMD Athlon X2 3800+ CPU (operating at 1800Mhz or higher)
2 x 1024MB of DDR2-667 DRAM
Discrete GPU recommended for HybridPower
At least 256MB of Frame Buffer carve out for the motherboard GPU
4-2
Chapter 4: NVIDIA® technology support
