Tyan Computer B5102, GX21 manual HDD Power Down, CPU THRM-Throttling

HDD Power Down

Also known as Hard Disk Timeout or IDE Standby Power Down Mode, this setting allows automatic power down of IDE drives after a specified period of inactivity 10 minutes is a suggested minimum, to avoid undue wear and tear on the drive. The choices are:

Disabled / 1 minutes / 5 minutes / 10 minutes / 30 minutes / 45 minutes / 60 minutes

CPU THRM-Throttling

This BIOS feature determines the clock speed of the proces- sor when it is in the Suspend To RAM (STR) power saving mode. It has no effect when the processor is in normal active mode.

Available options for this BIOS feature are preset values of the processor's power consumption. They range from 12.5% to 87.5%. Please note that these options reflect the desired power consumption of the processor, not its clock speed. The clock speed of the processor will be determined based on the option chosen.

The default setting is usually 62.5%. This means the proces- sor will be running at a clock speed that allows it to use 37.5% less power.

The choice of what you should set the processor to run at is really up to you. The lower the value, the more power you will save when the processor is in Suspend To RAM mode. Gen- erally, it would be nice to minimize power consumption while in Suspend To RAM mode. The only potential drawback might be a slightly longer time required to bring the processor back to speed.

It is common for this BIOS feature to be mistaken as a BIOS control for the Pentium 4's Thermal Monitor feature. How- ever, the clock throttling provided by this BIOS feature is completely different from the Pentium 4's Thermal Monitor feature. The possible values are:

87.5% / 75.0% / 62.5%/ 50.0%/ 25.3%/ 12.5%
