1.8 System Memory
The top-left edge of the PCA-6186 contains two sockets for 184-pin dual
in-line memory modules (DIMMs). Both two sockets use 3.3 V unbuf-
fered synchronous DRAMs (DDR SDRAM). DIMMs are available in
capacities of 64, 128, 256, 512 MB, or 1 GB. The sockets can be filled in
any combination with DIMMs of any size, giving your PCA-6186 single
board computer between 64 MB and 2 GB of memory. Use the following
table to calculate the total DRAM memory within your computer:
