Helpful notes:
1. ECC memory is designed to detect and correct single-bit errors, making it more reliable in critical systems.
2. Dual rank memory modules can improve memory performance in certain applications, but may not be compatible with all systems.
3. DDR2-667MHz is a relatively slow memory speed by modern standards, and may not be suitable for high-performance computing tasks.
