A system board has four 32-bit RIMM slots. If you installed one RIMM, which actions can you take?

The correct choice reflects the functionality of RIMM technology, particularly in the context of a system board equipped with RIMM (Rambus Inline Memory Module) slots. When one RIMM is installed, it is possible to install additional RAM modules to maximize the memory capacity of the system. The presence of continuity modules also allows for flexibility in managing memory configurations.

Continuity modules are used in a situation where all slots cannot be filled with RIMMs; they serve to maintain the electrical continuity of the memory bus. This means that if you have one RIMM installed in a system with four slots, you can either add more RIMMs to fully utilize the capacity or strategically place continuity modules in the unused slots to ensure the system functions correctly.

This combination allows for effective memory installation while adhering to the specific requirements of Rambus architecture. It is important to recognize that simply installing more RIMMs without considering continuity modules could lead to problems if the configuration is not supported by the system design. Thus, the correct answer encompasses both options for maximizing RAM capacity and ensuring proper function through continuity devices.
