I know that "over"-clocking is the rage among some hardware geeks. However, I'm more interested in conserving electricity when all my computer is doing is downloading a 4GB iso.
I remember reading a post by a FreeBSD user that there's an OS feature that allows FBSD to be underclocked to Pentium I speeds, something like 100/200 MHz. Is there a similar feature in Linux for aggressive software- based underclocking? According to "cpufreq-info | grep Hz", I can slow down my AMD X2 4800 to "at most" 1GHz. That's still way faster than the system it replaced a Duron 600: hardware limits: 1000 MHz - 2.50 GHz available frequency steps: 2.50 GHz, 2.40 GHz, 2.20 GHz, 2.00 GHz, 1.80 GHz, 1000 MHz current policy: frequency should be within 1000 MHz and 2.50 GHz. current CPU frequency is 1000 MHz. cpufreq stats: 2.50 GHz:3.60%, 2.40 GHz:0.17%, 2.20 GHz:0.17%, 2.00 GHz:0.12%, 1.80 GHz:3.59%, 1000 MHz:92.36% (3262) hardware limits: 1000 MHz - 2.50 GHz available frequency steps: 2.50 GHz, 2.40 GHz, 2.20 GHz, 2.00 GHz, 1.80 GHz, 1000 MHz current policy: frequency should be within 1000 MHz and 2.50 GHz. current CPU frequency is 1000 MHz. cpufreq stats: 2.50 GHz:3.60%, 2.40 GHz:0.17%, 2.20 GHz:0.17%, 2.00 GHz:0.12%, 1.80 GHz:3.59%, 1000 MHz:92.36% (3262) _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List http://lists.linux.org.ph/mailman/listinfo/plug Searchable Archives: http://archives.free.net.ph
