When putting in memory, you must put in the correct number of bits.  A SIMM is
only 8 bits (plus parity).

a 286 is a 16 bit bus so 2 SIMMs are needed
a 386SX is a 16 bit bus so 2 SIMMs are needed
a 386DX is a 32 bit bus so 4 SIMMs are needed
a 486 (SX or DX) is a 32 bit bus so 4 SIMMs are needed.


You could use 2 4Meg SIMMs and 2 2Meg SIMMs in a DX, but it will only register
4Meg.
