From: thufir Date: 2012-03-17T19:47:55+09:00 Subject: underclocking or CPU frequency scaling I have an older desktop: motherboard: SiS-661GX CPU: Intel(R) Pentium(R) 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, Thufir
