Underclocking or CPU frequency scaling

Ruby
1

I have an older desktop:

motherboard: SiS-661GX
CPU: Intel® Pentium® 4 CPU 2.53GHz

and would like to set a “max” for CPU usage to prevent overheating.
Generally, it’s fine, but for some processes I want to set a sort of
“nice” so that the CPU doesn’t get pegged. Longer compiles would be
fine.

Frequency scaling and underclocking can only be done through supported
hardware, generally the BIOS?

thanks,

If you has a motherboard has not been altered, and that motherboard
allows
the CPU to overheat during normal operation, then something is
defective.
The cooling equipment on your motherboard is designed to keep everything
nominal regardless of what computations are going on.

Absolutely true.

thanks, I posted this to the wrong list by accident. Yeah, I need a new
heatsink. However, cpulimit does the magic I was after :slight_smile:
