CT6472AF667.9FD4E4 - Crucial 512MB DDR2-667MHz PC2-5300 ECC Fully Buffered CL5 240-Pin DIMM Memory Module

Technical specs:
- Memory Type: DDR2 SDRAM
- Capacity: 512MB
- Speed: 667MHz (PC2-5300)
- Latency: CL5
- Pin Count: 240
- Error Correction Code (ECC): Yes
- Buffered/Registered: Fully Buffered

Helpful notes:
- ECC memory is designed for servers and workstations, providing extra reliability and error correction capabilities.
- Fully Buffered memory modules have an additional buffer chip, which can improve stability and reduce electrical load on the memory controller.
- DDR2-667 is a relatively slow memory standard by today's standards, but it may still be useful for older systems or specific applications.
