UNBELIEVABLE!! v2.0

Ok, I now have the Duron 650 all the way to 933. But the method of doing so is wierd. I have to place the jumper on the 100 mhz FSB setting then go into BIOS, set the core voltage to 1.700(1.81), the I/O voltage to 3.45 (3.5) and the multiplier to 7, then i use Slight adjust and change the FSB to 128 mhz. After saving BIOS it reboots but wont post. So I shut the power off and then back on. Bingo...it's boots and posts at 933 mhz. Runs stable from here on. But when I have Windows restart or shutdown, it's back to square one. I have to do the whole procedure all over again. What could be causing this? I don't think it's heat related as it idles at 47 degrees.

Seems familiure to me, it's some simple instability. Just raise voltage a bit more and/or try to lower your temps and you will get there. Succes!

I had a similar problem - the system would only boot at certain settings after some bizarre routine like swtiching the power off, then pressing the ATX and reset switches twice. I solved it by using conductive paint to unlock the chip rather than a pencil, so that's something you might want to look at. Otherwise, as Murphy says just try to lower your temps and meybe raise the voltage a bit more. Personally I'd go for lower temps before raising the voltage any more, but you could try it as an experiment to see whether it solves the problem. I seem to remember you were thinking about the Glaciator - sounds like the best choice, I have no doubt when you get it and get those temps under control you'll see a fair bit more out of that chip 8-)
