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 third­party 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. Do NOT use a 3.3V AGP card on the AGP slot of this motherboard!
It may cause permanent damage!

2. The maximum shared memory size is defined by the chipset vendor and
is subject to change. Please check SiS

3. Power Management for USB 2.0 works fine under Microsoft
XP SP1 or SP2 / 2000 SP4.

4. Featuring an advanced proprietary hardware and software design,
Intelligent Energy Saver is a revolutionary technology that delivers
unparalleled power savings.

5. ASRock Instant Flash i s a BIOS flash utility embedded in Flash ROM.
This convenient BIOS update tool allows you to update system BIOS
without entering operating systems first like MS-DOS or Windows®. With
this utility, you can press <F6> key during the POST or press <F2> key to
BIOS setup menu to access ASRock Instant Flash. Just launch this tool
and save the new BIOS file to your USB flash drive, floppy disk or hard
drive, then you can update your BIOS only in a few clicks without prepar­ing an additional floppy diskette or other complicated flash utility. Please
be noted that the USB flash drive or hard drive must use FAT32/16/12 file
system.

6. 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. The CPU host frequency of this motherboard is determined by the
jumper-setting. You must set the FSB jumper according to your AMD CPU
before you use the “Manual” option as the FSB setting in BIOS setup to
perform over clocking. Please check page 24 for details.

7. 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.

8. EuP, stands for Energy Using Product, was a provision regulated by European
Union to define the power consumption for the completed system. According
to EuP, the total AC power of the completed system shall be under 1.00W in
off mode condition. To meet EuP standard, an EuP ready motherboard and an
EuP ready power supply are required. According to Intel’s suggestion, the EuP
ready power supply must meet the standard of 5v standby power efficiency
is higher than 50% under 100 mA current consumption. For EuP ready power
supply selection, we recommend you checking with the power supply manu­facturer for more details.
