You may find that your 386SX mother board has a jumper selection option
for the clock speed.  The first 386SX-16 I owned had one of these, I just
moved the jumper and the system ran just fine.  The memory chips in the
system were already of a fast enough speed to handle the new clock rate.

I asked two friends in the PC business about this and both replied they
had done similar things and found that most (but not all) systems would
run just fine at the higher speed. Your mileage may vary, etc.
