My sys: A7V, PC133, FSB=100, RAM=133, CPU runs at 100x8=800. I too use win2k, ASUS Probe to monitor temp and fan speed. I can run it at 100x8.5 or 100x9 rock stable, but I will need to rise voltage, which may bring up the CPU temp to 55c (1% CPU usage). I've not tested 950mhz or higher, because the heat problem. But I did see other guy who overclocked Duron 700 to 950 but can't go any faster (otherwise will become unstable) even with powerful cooling (50c all the time).
