  It's impossible to answer for certain without knowing exactly what kind of
motherboard you have, but generally SIMMs run at 5v and most DIMMs at 3.3v;
the result is that relatively few boards will properly handle a mix of the
two.  [I do have some boards that claim they can handle any mix of SIMMs and
DIMMs, but in fact I've never tried that -- my DIMMs are in machines that run
the bus at 100 MHz, which no SIMMs are rated for.]

  I second the recommendation that you remove the SIMMs and install a DIMM,
although if I knew what motherboard (or, more specifically, what chipset) and
what applications you use, I might recommend 128MB rather than 64MB.
  You need to determine exactly what sort of DIMMs your board needs, but if
it can handle SDRAM, I'd get a DIMM that's rated for "PC100".  Don't throw
out your SIMMs -- odds are good that PC100 SDRAM will work in your next
motherboard, and at that point you can reinstall your SIMMs in this board to
make a hand-me-down, garages sale, or spare machine.
