Helpful Notes:
1. ECC memory is designed to detect and correct errors in data that is being read from or written to memory, ensuring data integrity.
2. Fully Buffered memory is designed to reduce the load on the memory controller, allowing for more memory modules to be installed in a system.
3. Dual Rank memory provides better performance than Single Rank memory, as it allows for more data to be accessed at once.
