1.9 System Memory
The top-left edge of the PCA-6179 contains three sockets for 168-pin
dual inline memory modules (DIMMs). All three sockets use 3.3 V
unbuffered synchronous DRAMs (SDRAM). DIMMs are available in
capacities of 16, 32, 64, 128, 256 or 512 MB. The sockets can be filled
in any combination with DIMMs of any size, giving your PCA-6179
single board computer between 16 MB and 1.5 GB of memory. Use
the following table to calculate the total DRAM memory within your
computer:
Table 1-8: DIMM module allocation table
Socket number 168-pin DIMM memory
1 (16, 32, 64, 128, 256 or 512 MB) x 1
2 (16, 32, 64, 128, 256 or 512 MB) x 1
3 (16, 32, 64, 128, 256 or 512 MB) x 1
1.9.1 Sample calculation: DIMM memory capacity
Suppose you install a 128 MB DIMM into your PCA-6179's socket 1
and a 32 MB DIMM into sockets 2 and 3. Your total system memory
is 192 MB, calculated as follows:

1 128 MB x 1 128 MB
2 32 MB x 1 32 MB
3 32 MB x 1 32 MB
