A technician is upgrading memory on a laptop that is experiencing performance issues. Which of the following RAM types should most likely be specified for installation?

ECC (Error-Correcting Code) DIMMs are typically used in server and workstation environments where data integrity is critical. While they enhance reliability by correcting memory errors, they are not compatible with most consumer laptops and do not fit the form factor required for laptop installations.

High latency DDR5 would negatively impact performance rather than improve it. Latency refers to the delay before a transfer of data begins following an instruction, and a higher latency RAM module would contribute to slower performance, contrary to the technician's goal of resolving performance issues.

Registered DIMMs are designed for servers and high-performance computing systems, providing better stability under heavy loads by buffering memory addresses. However, they are not suitable for laptops that typically require unbuffered memory modules for compatibility and effective performance.
