Oops... I'm currently using it - P166 MMX in the mobo designed for P133
maximum... It was hot, when I touched it, when I ran it for a bit with an
open cover, but then I closed the cover, ran it for a while (~half an
hour), opened  again - I could hold my finger on the heat sink without any
damage to either:-) The manual certainly doesn't specify the possibility
of using a P166 in it... What's 'silkscreen'? Today it has been up for
almost 5 hours already (in a row), no smoke so far... I'll turn it off
for now, maybe will put back P75 and seek further info.

Thanks for the warning!
