Option Installation 3-9
When upgrading your system memory, note the following conditions:
Be sure to use 168-pin 3.3V DIMMs with gold-plated contacts.
Bus speed of 100 MHz is supported.
Non-Error Correcting and Checking (64-bit) DIMMs are supported.
Note:
Although memory size may vary, the S DRAM
DIMMs must meet the Intel 4-clock, 100-MHz, unbuffered
SDRAM DIMM specification for 64-bit SDRAM.
Use the following procedure to:
Check the memo ry installed in the system
Determine the DIMM configuration needed to increase memory
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 complet e list of all memo ry configur a tions.
