[. . . ] (Default: Auto) Allows you to set the PWM frequency for Channel A and Channel B memory. The adjustable range is from 300. 0KHz to 500. 0KHz. (Default: Auto) Allows you to set the PWM frequency for Channel C and Channel D memory. The adjustable range is from 300. 0KHz to 500. 0KHz. (Default: Auto) Allows you to automatically change the PWM phase according to the CPU load. The power-saving levels are (from lowest to highest): eXm Perf (Extreme Performance ), High Perf (High Performance), Perf (Performance), Balanced, Mid PWR (Mid Power), and Lite PWR (Light Power). Auto lets the BIOS automatically configure this setting. (Default: Auto) Determines whether to allow memory voltage to drop to a power-saving level when the system is in S3 state.

This section provides memory voltage control options. && Reset Case Open Status Disabled Keeps or clears the record of previous chassis intrusion status. (Default)  Enabled   Clears the record of previous chassis intrusion status and the Case Open field will show "No" at next boot. - 50 - BIOS Setup && Case Open && CPU Vcore/CPU VRIN/CPU VCCIO/DRAM Channel A/B Voltage/DRAM Channel C/D Voltage/ DDRVPP Channel A/B Voltage/DDRVPP Channel C/D Voltage/+5V/PCH IO/PCH Core/+12V Displays the detection status of the chassis intrusion detection device attached to the motherboard CI header. If the system chassis cover is removed, this field will show "Yes", otherwise it will show "No". To clear the chassis intrusion status record, set Reset Case Open Status to Enabled, save the settings to the CMOS, and then restart your system. && CPU Temperature/PCH Temperature Displays the current system voltages. && 1st System Temperature/2nd System Temperature && CPU/CPU OPT/System Fan Speed Displays current CPU/CPU_OPT/system fan speeds. Displays current CPU/Chipset temperature. Displays current system temperatures detected by each system temperature sensor on the motherboard. && CPU/System(SYS_FAN1/2)/PCH Temperature Warning && CPU/CPU OPT/System Fan Fail Warning Sets the warning threshold for CPU/system/Chipset temperature. When temperature exceeds the threshold, BIOS will emit warning sound. Options are: Disabled (default), 60oC/140oF, 70oC/158oF, 80oC/176oF, 90oC/194oF. Allows the system to emit warning sound if the fan is not connected or fails. Check the fan condition or fan connection when this occurs. (Default: Disabled) Allows you to determine whether to enable the fan speed control function and adjust the fan speed. Normal   Allows the fan to run at different speeds according to the CPU temperature. You can adjust the fan speed with System Information Viewer based on your system requirements. (Default) Silent  Allows the fan to run at slow speeds. [. . . ] With your help, we can reduce the amount of natural resources needed to produce electrical and electronic equipment, minimize the use of landfills for the disposal of "end of life" products, and generally improve our quality of life by ensuring that potentially hazardous substances are not released into the environment and are disposed of properly. Appendix - 82 - FCC Notice (U. S. A. Only) This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
