What is CPU-Thermal Throttling?

Specs: XP, AMD XP 3000

Hi, I have a DFI Infinity II motherboard, and there is an option under advanced chipset features that reads "CPU-Thermal-Throttling" It has values that I adjust by the percentage, such as 37.5%, 50.0%, etc. What exactly does that do? Thanks

It throttles your processor speed to prevent it from burning up, the % I guess would represent the index by which the Mhz lowered.

This same concept is what Intel uses in some of its procesors like the P4 to prevent the CPU from "frying".

B4 you criticize a bigger man, walk a mile in his shoes. That way, you're a mile away, and you have his shoes.

This BIOS feature determines the clock speed of the processor 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 set values of the processor's power consumption. They range from a low of 12.5% to a high of 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 processor 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. Generally, 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. However, the clock throttling provided by this BIOS feature is completely different from the Pentium 4's Thermal Monitor feature.

Thanks for pointing that out.

No credit to me.I just copy/pasted it from rojakpots Bios Optimization Guide.
