I used to run a machine that was a 486DX4/100 with it's 'internal cache' disabled as I didn't have a heatsink... Just by disabling the internal cache the machine ran like a dog, but the chip would barely get warm... I guess the same would apply for underclocking - just be careful about busses that might derive their clock from the CPU's speed (especially on older machines). I guess it might make sense to some people - I always prefer to have 'more than adequate' cooling though... ;-) Regards, Karl Pielorz On Thu, 7 May 1998, Greg Shenaut wrote: > > I'm wondering if it might be possible to *underclock* > a CPU chip in order to increase its reliability, especially > under hot conditions.
