Hi,
Reporting on a little discussed utility that I'd forgotten about ...
http://www.zone6400.com/Sonnet_Clocker.html
Sonnet Clocker (use the rev. 1.2 version) is a utility that edits the Sonnet G3 extension to adjust the multiplier of a L2 or Nubus based Sonnet branded G3 accelerator. I'd never heard of successful software overclocking on Mac hardware, but can confirm I can overclock a Sonnet G3 400Mhz (1MB cache) L2 accelerator in my TAM to 500Mhz, as confirmed in benchmarks. Running at 500Mhz, it gets hot and I have replaced thermal grease on the card and intend to install a small fan nearby to dissipate some heat from the cramped TAM internals. Of note, it did not work at 450Mhz, I believe G3 revision and multiplier support is the key here.
Next I'll try it on a Sonnet Nubus G3 300Mhz card. Results may vary for you and on particular hardware.
