RAM must be installed four sticks at a time in the IIci, so most 
likely, the problem is that you have only two slots of a four slot 
"bank" filled.

The CPU in the IIci uses 32 bits of data at a time.   So the RAM must 
send 32 bits of data to it at the same time.  30 pin SIMMs are only 8 
bits wide.  So it takes four identical 30 pin SIMMs acting in concert 
to provide the required 32 bits of data width.

Max RAM on the IIci is 128 MB.  When you consider that the machine 
came out in something like '91 that's amazing.   PC 30 pin SIMMs are 
the same as Mac ones.   Some PC SIMMs  provide a parity bit, but 
they'll still work fine in the Mac.  The parity bit will just be 
ignored.
