If my clock ratio is fixed to 9x, this would explain. It's running a little warmer than at 66.8MHz x 8 = 566, (? clock ratio) but nothing you could cook on. I've installed cpuburn to my HD, really I want to run it from a floppy, like memtest86. Just in case ;-) AFAICT, so long as I keep it cool enough, it could well be stable at this setting. TBH I'd say it's actually performing like a well tuned 600. Which is what I want. We will see :-] I think it helps that I'm using harmonic ratios based on the recommended defaults. How hot is too hot? I've got my warning level set to 50deg in the BIOS and I still don't think I'm running under 40. It's hard to tell without rebooting, unfortunately although I have both the hardware and software for i2c & hwmon they're not talking at present. Again, it's something I never really bothered with before. Most of the heat is coming off the power supply. What started out as an idle comment has turned into a bit of a journey of discovery! Thanks for all the comments and suggestions. cheers tim hall
