CAUTION! 1. This motherboard is equipped with two types of CPU sockets. You may choose to install either AMD 939-Pin CPU or AMD 754-Pin CPU into this motherboard. However, to avoid instability and damage to the system, please do not install both of them into this motherboard. 2. For power-saving sake, it is strongly recommended to enable AMD's Cool 'n' QuietTM technology under Windows system. See APPENDIX on page 39 to enable AMD's Cool 'n' QuietTM technology. 3. If you install a 939-Pin CPU into this motherboard, please refer to page 14 for proper installation of memory modules on DDR1, DDR2, and DDR3. 4. If you install a 939-Pin CPU into this motherboard, it will support Dual Channel Memory Technology. Before you implement Dual Channel Memory Technology, make sure to read the installation guide of memory modules on page 14 for proper installation. 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. Do NOT use a 3.3V AGP card on the AGP slot of this motherboard! It may cause permanent damage! 7. 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 8. For microphone input, this motherboard supports both stereo and mono modes. For audio output, this motherboard supports 2-channel, 4-channel, 6-channel, and 8-channel modes. Please check the table on page 10 for proper connection. 9. 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. 8
