AMD Athlon64 4000+ Underclocking

Posted by CowboyNeal on from the slowing-things-down dept.

Bios_Hakr writes "PC Stats is running an article on their experiences underclocking an AMD 4000+ processor. Their goal was to try and reduce the voltage requirements and lower the heat output. They benchmark using 3dMark01, 3dMark05, as well as SuperPi. From the article: 'This got us thinking though; what about under-clocking? Most modern processors and motherboards can just as easily run under a rated speed as it can run over... but is there a point to this? Well possibly.'"

    Microsoft operating systems and software accomplish this without all the work.

    If they want to underclock a 4000+, they could just swap me my 3000+.. I wouldn't complain.

    I've got my system cranked to 200 millhertz!*
    Beat that ya loozers!

    * Footnote: No system stability problems detected yet.
    I'll post a confirmation follow-up when the standard stability test suit finishes running.

      I've got you beat. My clock rate is 0 Hz. I also know it's perfectly stable; there's no way it can crash! Even though it's passively cooled, it's 0 degree above ambient and totally silent.

    PC Stats actually took this idea from me. I took the same processeor, unplugged the computer (to lower power consumption) and then stuck it in a freezer (to lower temperature). Wow! Also nil power consumption (the freezer uses some to keep it cool) and the temp is really low! Next I'm going to try this with my laptop because the bottom of it gets really hot!

    Not a bad strategy, but it'd be much more efficient if you watercooled the CPU rather than aircooling it (which is what you effectively do when you put it in a freezer). Just take your case and place it in the bathtub (you can even soak in the bath with it if you want!). As far as lower power consumption goes, you'll notice a huge power spike for the first tenth of a second or so, but afterwards power consumption effectively drops to zero (along as your heart rate, if you're in the tub).

    Use a USB external drive (if your system can boot from USB) and keep it in a closed drawer.
