With a system board having four RIMM slots and only one RIMM installed, what can you do next?

1. Add two more RIMMs to fill the slots

2. Install three continuity modules

3. Use one more RIMM for optimal performance

4. Replace the RIMM with DDR modules

The correct answer is: Install three continuity modules

In a system board designed to utilize RIMM (Rambus Inline Memory Module) technology, it's crucial to understand how memory must be configured properly for the system to run effectively. In a scenario where there is only one RIMM installed in a system with four RIMM slots, using continuity modules is necessary to ensure the proper functioning of the memory subsystem. Continuity modules serve as placeholders in memory slots that are not populated with RIMMs. When only one RIMM is installed, and the other slots remain empty, continuity modules fill the remaining slots to maintain electrical signaling and stability. Without these modules, the memory controller may not recognize the installed RIMM, resulting in system instability or failure to boot. Adding more RIMMs or attempting to replace the existing RIMM with DDR modules is not viable under these circumstances. RIMM technology is specific and generally cannot be mixed with other types of memory like DDR, and simply adding more RIMMs without continuity modules would not resolve the configuration issue.
