4: Chassis Setup and Maintenance

DIMM Module Types and Optimal Configuration

For memory to work properly, install memory according to the specifications in Table 4-4 and

Table 4-5.

Notes:

• Due to OS limitations, some operating systems may not show more than 4 GB of memory.

• Due to memory allocation to system devices, the amount of memory that remains available

for operational use will be reduced when 4 GB of RAM is used. The reduction in memory

availability is disproportional. (See Table 4-5.)
