Helpful Notes:
1. ECC memory is designed to detect and correct single-bit errors, making it more reliable than non-ECC memory.
2. Registered memory modules are typically used in servers and other high-end systems to improve stability and performance.
3. Single rank memory modules have a single set of memory chips on each side, while dual rank modules have two sets of memory chips on each side, which can affect performance in certain situations.
