Bonjour Jean!
Thanks for your report, could you grab a new version of the script and see what
it recommends now.
Depending on your chipset is and what it suggests, could you try:
sudo modprobe speedstep- something. o coppermine=1
and let me know if that does/doesn't work. I think your chip should be able to
switch between 850Mhz and either 500Mhz or 400Mhz depending on which CPU
revision it is.
Many Thanks,
Paul
