'I'd heard that Intel prevents PIIIs from being overclocked. Was that just a "feature" of the Slot 1 P3s?'
The pIII's are clock locked, you cannot adjust the multiplier. You can however raise the fsb, this unfortunatly pushes the PCI and AGP buses out of spec, causing general system instability with components that rely heavily on timing (NIC's, etc.)
'but if U do a bad connection.....50°C; 60°C; 100°C....
pshhhhhh no more processor!!!!!!!!!!!!!'
No, i'm not aware of that happening at all, quite apart from the fact you seem to think this is anything to do with Intel processors. Not correctly closing all four L1 bridges on Duron or Thunderbirds results in (in my experience):
(1) The system not POSTing
(2) Multiplier adjustment via motherboard still impossible
(3) _some_ multipliers not attainable when set by the motherboard.
Removing all the pencil or closing all the bridges fixes any problems.
'I read an article about someone overclocking a PIII w/ a pencil. now, this was really clever, they united the L2 bridges '
It's the four L1 bridges, for Socket A AMD chips (Thunderbird, Duron). There was a rumour started on usenet that applying 12v to certain traces on p3 cartridge format chips set the multiplier. It turned out to be a hoax, that only succeeded in breaking quite a few people's chips.
'The pentium Itanium is going fairly well tough'
Check some hardware sites, the Itanium is far behind shipping date, has huge power requirements, and isn't particularly fast. It requires a very complex compiler to get decent speed, and it takes years to perfect compilers.
