Hmm, I just tested one...

A 16F628-20I/P    (Yes, I only have those cool Industry chips...)
Speed is measured with multimeter on clkout.

It gave me the following clock readings for 4.89 volts:
normal(25c): 1019 kHz
soldering iron on chip untill it hurts to touch it: 1027 kHz
ice balanced on top of chip: 1013 kHz

Now, at 6.1 Volts i get:
normal(25c): 1026 kHz
soldering iron on chip untill it hurts to touch it: 1028 kHz
ice balanced on top of chip: 1021 kHz

That wasn't so bad?

Another chip gave me 1024 at normal temp...
They ar probably from same batch, but it seems very good :-)
