The Centris 660av and Quadra 660av are identical except for the name plate. They have 4 MB of RAM soldered to the motherboard and two 72-pin SIMM sockets for memory expansion.

With the rear of the computer away from you, you will see two SIMM sockets on the right side of the motherboard.

Each socket can be filled with a 4 MB, 8 MB, 16 MB, or 32 MB SIMM – they need not be of the same capacity – and covers a range from 4 MB to 68 MB of system memory. (There is no support for 1 MB, 2 MB, or 64 MB SIMMs.) The 72-pin SIMMs must be 70ns or faster. If you install two SIMMs, they should match in speed or you may have memory problems.
