PCA-6275 User's Manual
1.9 System Memory
The top-left edge of the PCA-6275 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, or 256 MB. The sockets can be filled in any combina-
tion with DIMMs of any size, giving your PCA-6275 single
board computer between 16 and 768 MB of memory. Use
the following table to calculate the total DRAM memory
within your computer:
Table 1-6: DIMM module allocation table
Socket number 168-pin DIMM memory
1 (16, 32, 64, 128 or 256 MB) x 1
2 (16, 32, 64, 128 or 256 MB) x 1
3 (16, 32, 64, 128 or 256 MB) x 1
1.9.1 Sample calculation: DIMM memory capacity
Suppose you install a 128 MB DIMM into your PCA-6275's
socket 1, a 32 MB DIMM into socket 2, and you leave
socket 3 empty. Your total system memory is 160 MB,
calculated as follows:
