Notes:
1. ECC memory is designed to detect and correct single-bit errors, ensuring data integrity.
2. Fully Buffered memory is a type of memory module that reduces the load on the memory controller, allowing for higher memory densities and greater reliability.
3. Dual Rank memory modules offer better performance than single rank modules, as they allow for more data to be accessed at once.
