Notes:
1. ECC memory is designed to detect and correct single-bit errors, making it ideal for use in servers and workstations.
2. Fully Buffered memory modules have an additional buffer chip that helps to reduce electrical load on the memory controller, improving stability and reliability.
3. DDR2 memory is an older standard that is no longer commonly used, but may still be required for some legacy systems.
