Notes:
1. ECC registered memory is designed for servers and workstations that require high reliability and error correction capabilities.
2. Buffered memory is also known as registered memory and is used to reduce electrical load on the memory controller, allowing for more memory modules to be installed on a single motherboard.
3. DDR-266MHz memory is considered outdated and may not be compatible with newer systems.
