My motherboard is jumpered for a standard 486DX or DX2.  I don't think
that makes any difference (the DX2 didn't have a clock multiplier pin;
it always doubled the clock no matter what).

My motherboard is 5-volt only.  The 3-volt regulator module that I
bought with the CPU has jumpers for both AMD and Intel chips on it.
The AMD jumper is for 2x and 3x.  The Intel jumper is for 2x, 2.5x and
3x.  Oddly enough, I get the best performance when I use the jumper
for Intel at 2x (I believe the 4x chips use the 2x pin to do 4x, since
there is no 4x pin -- you get 3x with the 3x setting, and 4x with the
2x setting).  So, I leave the AMD jumper open and jump the Intel
jumper to 2x (4x).
