At 75MHz bus clock, the K5-166 will 83 works great with my hardware. I do 83 * 1.5 and it beats out 75 * 1.75 for most of the stuff I do. (125 Mhz vs 132 Mhz, the win being on bus speed.)

I had stability probs at 1.75 * 75 until I upped the CPUs voltage a little bit, to 3.6 from 3.52. At 3.52 make world dies, 3.6 works fine. ta, Craig
