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 more stable and reliable than unbuffered memory modules, but they are slightly slower due to the additional buffering.
3. DDR2 memory is an older memory technology and is not compatible with newer DDR3 or DDR4 memory slots.
