Hi all,
Does anyone have a list of CPUs and their voltages? I'm just wondering what options I have with a socket 7 board that only does 3.3v
Cheers,
Steve

Pentium 54C, AMD K5, IDT Winchip C6, Cyrix 686. Although Pentium MMX was documented to work on such motherboards and can tolerate 3.3v.
I must be some kind of standard: the anonymous gangbanger of the 21st century.
Yep. If you can get your hands on a voltage regulating interposer, you can play with the lower voltage CPUs. Otherwise it's that list - and a few unobtanium MMX overdrives and integrated upgrade CPUs.
There are also versions of the K6-233 that require 3.2V or 3.3V. That would probably be the fastest option, provided the board supports the 3.5x multiplier.
Thanks all! The board doesn't do 3.5x unfortunately.
I never had the guts to try an MMX at 3.3v and I just tried an old school ceramic P200MMX and it's working perfectly! Getting a little warm so need to beef up the heatsink and fan.

Most likely it does. There is no separate 3.5x multiplier. Pentium MMX 233 interpret a 1.5x multiplier as 3.5x, so just set it to 1.5x use 233 MHz CPU and that should be it.
