DDR2-800 200-pin SO-DIMM
DDR2 SO-DIMM module standard. This record identifies a distinct product or standards-defined module class; specifications not verified for this exact identity are deliberately left open.
IDENTITY: DDR2-800 200-pin SO-DIMM is cataloged as ddr2 so-dimm module standard. Standards entries describe a module class; named manufacturer entries describe one SKU. Do not treat them as interchangeable records.
Recorded specifications
| Catalog identity | DDR2-800 200-pin SO-DIMM |
|---|---|
| Record type | DDR2 SO-DIMM module standard |
| Verified specifications | 200-pin small-outline DIMM; DDR2-800 (400 MHz clock, 800 MT/s effective transfer class); PC2-6400 bandwidth class. Standard voltage is 1.8 V; exact capacity, ranks, and timings vary by module. |
| Compatibility | Fits only DDR2 SO-DIMM slots; do not confuse with 200-pin DDR SO-DIMM, which has a different keying and signaling. Laptop chipset, BIOS, supported density, and maximum capacity must be checked. |
| Unverified/variable details | Only values supported by the cited standard or manufacturer source are stated. Confirm exact part number/revision, SPD, ranks, timings, and voltage on the specimen when not specified above. |
Platform compatibility and service
- Fits only DDR2 SO-DIMM slots; do not confuse with 200-pin DDR SO-DIMM, which has a different keying and signaling. Laptop chipset, BIOS, supported density, and maximum capacity must be checked.
- Before installation, record the full label, manufacturer, part number, revision/date code, contact condition, chip markings, and SPD contents where present.
- Use ESD precautions, handle the module by its edges, and never force it into a slot with different keying. Power down and follow the host’s service manual.
- For server/ECC modules, confirm CPU support, buffering type, channel population, supported ranks/densities, and firmware behavior; physical fit is not proof of ECC operation.
Archival and service notes
A form-factor and speed-class record, not a single manufacturer SKU. Record the module label and device/chip organization; aging laptops may accept only particular ranks or densities. Photograph both sides before cleaning; retain the host manual, SPD dump, test host, BIOS revision, and memory-test result with the catalog record.
