Memory
Main memory resides on an add-in board, called a memory module, designed specifically for the
SC450NX MP server. The memory module contains slots for 16 DIMMs, each of which must be
at least 32 MB, and is attached to the baseboard through a 242-pin connector. Memory amounts
from 128 MB to 4 GB of DIMM are supported, with a 64/72-bit four-way-interleaved pathway to
main memory, which is also located on the module. The 16 slots are divided into four banks of
four slots each, labeled A through D. These banks support 4:1 interleaving. The memory
controller supports EDO DRAMs. The ECC used for the memory module is capable of correcting
single-bit errors (SBEs) and detecting 100 percent of double-bit errors over one code word. Nibble
error detection is also provided.
