the K6's come precooked from the factory :-)

but i run my k6-II/200 at 233 or so without i'll effects. it's a pretty
old piece of silicon and i think the earlier chips had more 'intel-ish'
thermal safety margins.

i think AMD got braver about pushing the silicon as they got more
experience with the manufacturing process, so they end up *selling* the
slicon rated at a more aggressive clock speed.

but now i am inspired to try to bump mine to 250 and see what happens. :-)
it's my home gateway box and it never runs windows. usually i know that i
have been too ambitious when gcc barfs abruptly during a kernel compile...
