Externally, yes, though there is a way of modifying the onboard voltage regulator to change the voltage going to the chip itself. I'll be damned if I can remember the details of it, though, and I also recall it making little/no difference in the overclocking ability.
One other random tidbit about those things... IIRC they automatically switch to a 1X multiplier if you remove the built-in fan. (You'd want to attach an externally-powered fan in its place though.) That might provide some possibilities for testing a 66mhz bus speed.
Ummm...there are no socket 3 motherboards with a 66mhz bus setting. 😉
I am testing a Biostar 486 mobo with a working 66 MHz bus setting. Previously, I got a 100% overclock on an SX-33 to get it to run at 33->66 MHz, but I've just this very moment got the P75 chip running at a 3x multi = 198 MHz. And it works! I'll post more after I tweak the BIOS timings..
Edit: At the end of page 3 on this thread, I explain that the 66 MHz bus speed option does not work well for the P75 chip. It's OK for an SX-33, but either the P75 or the 60ns EDO RAM, or possibly both of these components can't cope with this bus speed.
