It is possible that your motherboard will simply not recognize any more than
32 MB of RAM in that DIMM slot.  I just upgraded (somewhat) a computer
for an office I help support.  I increased the RAM from 16 to 64 MB.  It was
not possible to do this using any combination of DIMM + SIMM, and the
DIMM slot was limited to 32 MB.  This was an Elite Group motherboard
(perhaps ca. 1997) and it also had 4 72-pin SIMM slots and one 168-pin
DIMM slot.  The manual gave many possible combinations up to a maximum
of 128 MB of RAM (if memory serves), and using a DIMM would have maxed
it out at 32 MB.  I don't even know if MHz speed of the RAM was a factor,
though I suspect that 66 MHz would be the limit.

Obviously I put in 4 16 MB SIMMS to get the RAM to 64 MB.  Definite
downside to this is that 72-pin SIMMS are
a) getting harder to find and
b) becoming quite a bit more expensive than their 168-pin DIMM counterparts.
