Helpful Notes:
1. ECC memory is more reliable than non-ECC memory as it can detect and correct single-bit errors.
2. Registered memory modules have a buffer that helps to reduce electrical load on the memory controller, making them better suited for use in servers and workstations.
3. The x4 chip organization means that each chip on the module has 4 banks, which can improve memory performance in certain applications.
