Sample Memory Configurations - NEC SP B-Series Service And Reference Manual

When upgrading your system memory, note the following conditions:
T
Be sure to use 168-pin 3.3V DIMMs with gold-plated contacts.
T
Bus speed of 100 MHz is supported.
T
Non-Error Correcting and Checking (64-bit) DIMMs are supported.
Note:
Although memory size may vary, the SDRAM
DIMMs must meet the Intel 4-clock, 100-MHz, unbuffered
SDRAM DIMM specification for 64-bit SDRAM.
Use the following procedure to:
T
Check the memory installed in the system
T
Determine the DIMM configuration needed to increase memory
T
Identify DIMM sockets.
Note:
If any cables block access to the DIMM sockets,
label and disconnect them. If any boards block access to the
sockets, remove them.
1. Locate the three DIMM sockets: J7J1–Bank 0, J6J2–Bank1, and
J6J1–Bank 2. See Appendix B to identify the sockets.
2. Use the following table to determine the DIMM configuration needed to
upgrade memory. The table provides sample memory configurations; it is
not a complete list of all memory configurations.
