Apple 661-4234 | 2GB DDR2-667MHz PC2-5300 non-ECC Unbuffered CL5 200-Pin SoDIMM Dual Rank Memory Module for MacBook

Technical Specs:
- Memory Type: DDR2 SDRAM
- Capacity: 2GB
- Speed: 667MHz (PC2-5300)
- Form Factor: 200-pin SoDIMM
- Error Correction: Non-ECC

Helpful Notes:
1. This memory module is specifically designed for use with MacBook models.
2. Non-ECC memory is generally less expensive than ECC memory, but does not provide the same level of error correction.
3. Dual rank memory modules are generally more efficient than single rank modules, as they can access more memory banks simultaneously.
