Hardware Installation 
Rule 2. Regardless of the number of RIMMTM modules used, the total number of devices must not exceed 32 devices.
Rule 3. Due to RDRAM’s signal routing, all SRIMM sockets must be populated with modules.This is to allow the Direct Rambus Channel to function properly. If a socket is not populated with RIMMTM module, YOU MUST install it with CRIMM (continuity module). If, at any time, you wish to upgrade the system memory, remove the CRIMM that is next to the existing RIMMTM module and replace it with another RIMMTM module - always taking into consideration rule 1.
RIMM1 socket is installed with a RIMM module.
RIMM2 socket is installed with a CRIMM module.
RIMM1 and RIMM2 sockets are installed with RIMM modules.
