Memory modules are the actual components that provide memory for the
microprocessor; continuity modules are used only to complete the memory
circuit if memory modules are not installed in all of the memory connectors.
Another RDRAM requirement is that memory modules must be installed in
pairs of matched memory size. This means that if you purchased your
computer with 128 MB of memory installed and you want to add another
128 MB of memory, you must remove the two continuity modules and
replace them with two 64-MB memory modules.
NOTICE: You can only install continuity modules in connectors RIMM 3 and
RIMM4.
The only two valid memory configurations are:
• A pair of matched memory modules installed in connectors RIMM1
and RIMM2 with continuity modules installed in connectors RIMM3
and RIMM4
or
• A pair of matched memory modules installed in connectors RIMM1
and RIMM2 and another matched pair installed in connectors RIMM3
and RIMM4
