I've run a both a K6 166 and 200 and never had a problem. Running rather strenuous tests (including a couple of make worlds) neither ever crashed a single time during weeks of uptime. I don't currently have one on the network at the house, here, but several are running on other locations which I somewhat oversee. Nobody has reported a problem back up to me yet. I would tend to check for adequate cooling (although I remember being impressed with how cool the 166 chip ran as opposed to the Cyrix (non L version) in the machine I'm on right now.), and especially the voltages. I honestly can't tell you what I ran them at, as I don't have either machine here. I do believe, that in the ASUS TX board (a TX97-E) with the 166, I was runing it at the higher of the two voltages closest to AMD's spec. The board didn't have the EXACT voltage that AMD specified, and it RAN with either the next lower, or the next higher, and I'm quite sure I was running it at the higher. It is at least worth looking into. I'm likely going to be swapping a K6 into my little rotation here at the house very soon, and I have yet to have any problems, although I currently do not use one in any of my main machines here. I've actually always had good luck with AMD chips. Hobbes (a 5x86-133 running at 150 Mhz) is up to 120 days uptime. :) Later......
