Intel ECB-865 Stand by Time Out Minute, Suspend Time Out Minute, Throttle Slow Clock Ratio

User’s Manual

4.3.4.4Stand by Time Out (Minute)

This option specifies the length of the period of system inactivity while the computer is in Full-On power state before the computer is placed in Standby mode. When this length of time expires, the computer enters Standby Timeout state. In Standby mode, some power use is curtailed.

4.3.4.5Suspend Time Out (Minute)

This option is the same as Stand by Time out function. These two features will be enabled to monitor power of sub-items “Display Activity”, “Serial port”, “Parallel Port”, “Floppy”, “Pri-HDD”, and “Sec-HDD” independently. It is also used to control CPU throttle running function. All of sub-items will be ineffective in selection of disabling “Stand by Time out” or “Suspend Time out” even if it can be choused by user in BIOS setup menu.

4.3.4.6Throttle Slow Clock Ratio

This option specifies the speed at which the system clock runs in power saving modes. The settings are expressed as duty cycle of the STPCLK# signal. This duty cycle indicates the percentage of time the STPCLK# signal is asserted while in the throttle mode.

4.3.4.7System Thermal

Set this option to Monitor for CPU thermal monitoring and speed down control. The system will automatically supervise the CPU environmental temperature. If the CPU surface temperature reaches the trip point set in Hardware Monitor Setup, the thermal detection will be effective and CPU will run in throttle control manner. The overall system performance will be reduced to half. This option is a trade-off of system performance and stability and configurable by user. The default setting is Ignore. You can choose Monitor setting to enable this thermal function.

4.3.4.8Thermal Slow Clock Ratio

This option specifies the speed at which the system clock runs in thermal trip point. The settings are expressed as duty cycle of the STPCLK# signal. This duty cycle indicates the percentage of time the STPCLK# signal is asserted while in the over heat mode.

4.3.4.9CPU Critical Temperature

Set this option to monitor CPU thermal trip point defined by user. If the System Thermal option in CMOS setup is set to “Monitor” state and CPU surface temperature is over this critical temperature, the system will automatically enter speed down mode.
