DDR3 ECC Registered DIMM (RDIMM)
DDR3 registered ECC server memory class. This record identifies a distinct product or standards-defined module class; specifications not verified for this exact identity are deliberately left open.
IDENTITY: DDR3 ECC Registered DIMM (RDIMM) is cataloged as ddr3 registered ecc server memory class. Standards entries describe a module class; named manufacturer entries describe one SKU. Do not treat them as interchangeable records.
Recorded specifications
| Catalog identity | DDR3 ECC Registered DIMM (RDIMM) |
|---|---|
| Record type | DDR3 registered ECC server memory class |
| Verified specifications | 240-pin DDR3 RDIMM class with register/buffer and system-level ECC check bits. Voltage, capacity, ranks, speed, and CAS timings vary across DDR3L/DDR3 revisions and module builds. |
| Compatibility | Requires a DDR3 RDIMM-compatible server memory controller and motherboard; incompatible with DDR3 UDIMM and most desktop boards despite the same broad DDR generation. Server population and CPU rules govern supported speed. |
| 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
- Requires a DDR3 RDIMM-compatible server memory controller and motherboard; incompatible with DDR3 UDIMM and most desktop boards despite the same broad DDR generation. Server population and CPU rules govern supported speed.
- 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
This is a module class, not a single product. Record whether DDR3 or DDR3L, voltage, rank, organization, registered buffer, and exact server platform before cataloging a specimen. Photograph both sides before cleaning; retain the host manual, SPD dump, test host, BIOS revision, and memory-test result with the catalog record.
