I have an IBM 6x86MX PR166 CPU says 2.9V on the top.. Would it run fine on motherboards rated for 2.8V/3.3V only (Pentium, MMX, 6x86, K5)? Or should I switch the motherboard out for one that has specific voltage settings for 2.9V?

Try it and see.
2.8V should be OK if your voltage is fairly stable. It won’t hurt but might crash if it doesn’t get enough juice.

If you are squeamish, don't prod the beach rubble.

Or just add 3.3v and overclock it.

I must be some kind of standard: the anonymous gangbanger of the 21st century.
