Longevity in controlled environments (10+ years MTBF).
Cost-effectiveness vs. full system replacement.
Alternatives Comparison
| Model | Size | Speed | Advantage |
|---|---|---|---|
| MT18HTF25672PKZ-80EH1 | 2GB | 800MT/s | Micron reliability |
| Samsung M395T2953EZ4 | 2GB | 667MT/s | Lower power |
| Hynix HMP325GF72MMR-80E | 2GB | 800MT/s | Wider availability |
Frequently Asked Questions
Q1: Is this module ECC-capable?
A: No, the MT18HTF25672PKZ-80EH1 is non-ECC. For ECC needs, consider Micron’s MT36HTF25672PY-80E1.
Q2: Can I mix this with other DDR2 speeds?
A: Not recommended. Systems typically clock all modules to the lowest speed (e.g., mixing 800MT/s and 667MT/s will downclock to 667MT/s).
Q3: What’s the operating voltage?
A: 1.8V ±0.1V, per DDR2 JEDEC standards.
Q4: Are there thermal limitations?
A: Rated for 0°C to 85°C (commercial grade). Industrial variants extend to -40°C to 95°C.
Q5: How to verify authenticity?
A: Micron provides batch-code verification via their website.
Future Outlook
While DDR2 production has ceased, niche markets will drive demand through 2030, particularly for:
Military/aerospace systems with long certification cycles.
Retro-computing enthusiasts.
Recommendation: For new designs, migrate to DDR3/DDR4 with backward-compatibility interfaces.
