MC-4R64CPE6C
Standard RIMM Module Marking
The RIMM modules are marked per Figure 1 below. This marking assists users to specify and 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. Information contained on the label is specific to the RIMM module and provides RDRAM information without
requiring removal of the RIMM module's heat spreader.
