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. About the setting of “Hyper Threading Technology”, please check page 31.
2. This motherboard supports Untied Overclocking Technology. Please read
“Untied Overclocking Technology” on page 27 for details.
3. Due to the chipset limitation, the actual memory size may be less than 4GB
for the reservation for system usage under Windows® XP and Windows
VistaTM.
4. 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.
5. 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.
6. Before installing SATAII hard disk to SATAII connector, please read the “SATAII
Hard Disk Setup Guide” on page 21 to adjust your SATAII hard disk drive to
SATAII mode. You can also connect SATA hard disk to SATAII connector
directly.
7. Power Management for USB 2.0 works fine under Microsoft® Windows
VistaTM / XP SP1 or SP2 / 2000 SP4.
8. Microsoft
