1.9 System Memory
The top-left edge of the PCA-6166 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, or 128 MB. The sockets can be filled in any
combination with DIMMs of any size, giving your PCA-6166 single
board computer between 16 MB and 384 MB 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, or 128 MB) x 1
2 (16, 32, 64, or 128 MB) x 1
3 (16, 32, 64, or 128 MB) x 1
1.9.1 Sample calculation: DIMM memory capacity
Suppose you install a 128 MB DIMM into your PCA-6166's socket 1
and a 32 MB DIMM into sockets 2 and 3. Your total system memory
is 192 MB, calculated as follows:
Table 1-9: DIMM memory capacity sample calculation
Socket number 168-pin DIMM memory Total memory
1 128 MB x 1 128 MB
2 32 MB x 1 32 MB
3 32 MB x 1 32 MB
Total memory 192 MB
