Helpful Notes:
1. ECC memory is designed to detect and correct single-bit errors, providing greater reliability.
2. Fully Buffered memory modules use a buffering system to reduce electrical loading, allowing for greater memory capacity.
3. Dual Rank memory modules provide better performance than single rank modules, especially in systems with multiple memory channels.
