1.3.3 Memory Board
Each memory board provides a memory access controller (MAC) and eight DIMM
slots (

power the server off.
TABLE 1-5 lists the memory board features.
To install DIMMs, you must remove the memory board and open the case of the
memory board. The servers use Double Data Rate II (DDR-II) type memory with the
following features:
■ Error Checking and Correction (ECC) error protection
■ Recovery from memory chip failures
FIGURE 1-9 and FIGURE 1-10 illustrate the location of the memory boards in both
