CAUTION!
1. While CPU overheat is detected, the system will automatically shutdown.
Please check if the CPU fan on the motherboard functions properly before
you resume the system. To improve heat dissipation, remember to spray
thermal grease between the CPU and the heatsink when you install the PC
system.
2. Do NOT use a 3.3V AGP card on the AGP slot of this motherboard!
It may cause permanent damage!
3. Power Management for USB 2.0 works fine under Microsoft® Windows®
XP SP1/2000 SP4. It may not work properly under Microsoft® Windows®
98/ME. Please refer to Microsoft® official document at
http://www.microsoft.com/whdc/hwdev/bus/USB/USB2support.mspx
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. 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.
