I agree, but see below... > I was able to overclock some of my 164LXen with 533 21164a to 600Mhz with > reliable > results, but switched back to 533 Mhz due to the above thoughts. Often the 533MHz 21164 processors were exactly the same as the 600MHz varitiy. The same _sometimes_ goes for the 500MHz processors, but not always. From what I remember (which could be fuzzy or plain wrong) is that the ones clocked at 500MHz were processors that failed to operate under certain conditions at 533MHz. I personally have overclocked a 21064 from 166MHz to 200Mhz for about a year and breifly tried it at 233MHz (day or so) but was afraid it would end up as a puddel in the bottom of the case... I currently have my 533MHz 21164 overclocked to 600MHz for more then a year and it's fine. I can wrap my fingers around the heatsink and it is cool to the touch (not hot, not even warm, but cool). So I believe it to be ok overclocked. I've built dozens of kernels for it and countless packages for Debian without finding a single error. JMO && YMMV Ron
