WARNING
Please realize that there is a certain risk involved with overclocking, including adjusting
the setting in the BIOS, applying Untied Overclocking Technology, or using the third-
party overclocking tools. Overclocking may affect your system stability, or even
cause damage to the components and devices of your system. It should be done at
your own risk and expense. We are not responsible for possible damage caused by
overclocking.
CAUTION!
1. This motherboard supports Untied Overclocking Technology. Please read
“Untied Overclocking Technology” on page 37 for details.
2. This motherboard supports Dual Channel Memory Technology. Before
you implement Dual Channel Memory Technology, make sure to read
the installation guide of memory modules on page 16 for proper
installation.
3. Whether 1066MHz memory speed is supported depends on the AM2+ CPU
you adopt. If you want to adopt DDR2 1066 memory module on this
motherboard, please refer to the memory support list on our website for
the compatible memory modules.
ASRock website http://www.asrock.com
4. Due to the operating system limitation, the actual memory size may be
less than 4GB for the reservation for system usage under Windows®XP
and Windows®VistaTM. For Windows®XP 64-bit and Windows®VistaTM 64-
bit with 64-bit CPU, there is no such limitation.
5. The maximum shared memory size is defined by the chipset vendor
and is subject to change. Please check AMD website for the latest
information.
6. 1080p Blu-ray (BD) / HD-DVD playback support on this motherboard requires
the proper hardware configuration. Please refer to page 10 and 11 for the
minimum hardware requirement and the passed 1080p Blu-ray (BD) / HD-DVD
films in our lab test.

11. Although this motherboard offers stepless control, it is not recommended
to perform over-clocking. Frequencies other than the recommended CPU
bus frequencies may cause the instability of the system or damage the
CPU.
12. While CPU overheat is detected, the system will automatically shutdown.
Before you resume the system, please check if the CPU fan on the
motherboard functions properly and unplug the power cord, then plug it
back again. To improve heat dissipation, remember to spray thermal
grease between the CPU and the heatsink when you install the PC system.
13. This motherboard supports ASRock AM2 Boost overclocking technology. If
you enable this function in the BIOS setup, the memory performance will
improve up to 12.5%, but the effect still depends on the AM2 CPU you adopt.
Enabling this function will overclock the chipset/CPU reference clock. However,
we can not guarantee the system stability for all CPU/DRAM configurations.
If your system is unstable after AM2 Boost function is enabled, it may not be
applicative to your system. You may choose to disable this function for
keeping the stability of your system.

HDCP Function
HDCP function is supported on this motherboard. To use HDCP function
with this motherboard, you need to adopt the monitor that supports
HDCP function as well. Therefore, you can enjoy the superior display
quality with high-definition HDCP encryption contents. Please refer to
below instruction for more details about HDCP function.
What is HDCP?
HDCP stands for High-Bandwidth Digital Content Protection, a
specification developed by Intel®for protecting digital entertainment
content that uses the DVI interface. HDCP is a copy protection
scheme to eliminate the possibility of intercepting digital data
midstream between the video source, or transmitter - such as a
computer, DVD player or set-top box - and the digital display, or
receiver - such as a monitor, television or projector. In other words,
HDCP specification is designed to protect the integrity of content as it
is being transmitted.
Products compatible with the HDCP scheme such as DVD players,
satellite and cable HDTV set-top-boxes, as well as few entertain-
ment PCs requires a secure connection to a compliant display. Due
to the increase in manufacturers employing HDCP in their equipment,
it is highly recommended that the HDTV or LCD monitor you purchase
is compatible.
