HP 453057-001N | 2GB DDR2-667MHz PC2-5300 non-ECC Unbuffered CL5 200-Pin SoDimm 1.8V Memory Module

Technical Specs:
- Memory Type: DDR2 SDRAM
- Memory Size: 2GB
- Memory Speed: 667MHz (PC2-5300)
- CAS Latency: CL5
- Pin Count: 200
- Form Factor: SO-DIMM

Helpful Notes:
1. This memory module is compatible with laptops and other mobile devices that support DDR2 SO-DIMM memory.
2. The 667MHz speed provides a decent boost in performance compared to slower DDR2 memory.
3. Non-ECC memory is generally cheaper than ECC memory, but does not provide the same level of error correction.
