The Performa-550 has 4Meg soldered on the Motherboard and one open SIMM 
slot that can accept a 1Meg, 4Meg, 8Meg, 16Meg, or 32Meg SIMM.  The 
memory needs to be 80ns or better and the SIMM is a 72-pin, parity or 
non-parity will work.  Since parity SIMMs work you can use PC SIMMs and 
they are typically cheaper that "Mac" memory SIMMs.  A good source for 
memory is:

p.s. The internal disk can also be upgraded.  Mine currently sports a 
4.3Gig Quantum which runs fine with the GENERIC kernels.
