I've been wondering about this since I was wanting to try to emulate a hyper-fast Voodoo 1 in PCem, but I want it to be at a speed that actually existed back in the day.
Someone will be along to disprove me shortly, but I believe they're all clocked the same by default. Same with the Voodoo2.

There could've always been a factory overclocked model of some sorts. I did do a bit of quick reading and apparently all V2s came with 100MHz clocked memory anyway (though usually clocked at 90MHz).

Never seen anything else than 50 MHz for Voodoo1. But I recall some vendor using 95 MHz on Voodoo2.
Well, is it even possible to overclock a Voodoo 1? If so, how high can you go?

Dunno. Iirc the Diamond Rendition 2100s could be overclocked by powerstrip? They are about the same era so perhaps the V1 could be overclocked using that program (I wouldn't recommend overclocking a V1 though, seems kinda pointless, but that's just me)
It's possibile to overclock a Voodoo1 by adding the command "SET SST_GRXCLK=xx" in Autoexec.bat. xx is the frequency in MHz.
Diamond Monster 3D driver has an option to automatically set it to 57 Mhz!

Usually not more than 10%, early 3dfx hardware was pushed to the max.
I've ran mine on 58mhz without problems. I wouldn't dare push it further without a heatsink attached though.

60MHz was reachable according to http://www.tomshardware.com/reviews/real-thing,45-2.html
The two 3Dfx Voodoo cards were both clocked to 60 MHz, which is just fine in case of the Canopus Pure3D with its 35 ns EDO RAM but beyond good or bad for the Diamond Monster 3D unless you cool it. I did this only for comparing the drivers of these two cards to each other, the Monster shouldn't run higher than 57 MHz and hence in real world it's slower than shown here.
