Rambus RIMM Modules
Standard RIMM Module Marking
The RIMM modules available from INFINEON Technoligies will be marked per Figure 3 below. This
marking will help OEMs and users identify the Rambus RIMM modules when used in specific
system applications. This will assist OEMs or users to specify and correctly verify if the correct
RIMM modules are installed in their systems. In the diagram, a label is shown attached to the RIMM
module’s heat spreader.
