Helpful Notes:
1. ECC memory is designed to detect and correct errors that may occur during data storage and transmission.
2. Fully buffered memory is a type of memory module that uses an advanced buffering system to reduce signal noise and improve signal integrity.
3. Dual rank memory modules have two sets of memory chips that can be accessed simultaneously, which can improve memory performance in certain applications.
