1.7System Memory

The top-left edge of the PCA-6359 Series contains three sockets for 168-pin dual inline memory modules (DIMMs). All three sockets use

3.3V 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-6359 Series single board computer between 16 MB and 256 MB of memory. Use the following table to calculate the total DRAM memory within your computer:

Table 1-5: 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

1.7.1 Sample calculation: DIMM memory capacity

Suppose you install a 128 MB DIMM into your PCA-6359 Series' socket 1 and a 32 MB DIMM into socket 2. Your total system memory is 160 MB, calculated as follows:

Table 1-6: 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
Total memory			160 MB
