DDR5 ECC Registered DIMM (RDIMM)
DDR5 registered server module class. This record identifies a distinct product or standards-defined module class; specifications not verified for this exact identity are deliberately left open.
IDENTITY: DDR5 ECC Registered DIMM (RDIMM) is cataloged as ddr5 registered server module class. Standards entries describe a module class; named manufacturer entries describe one SKU. Do not treat them as interchangeable records.
Recorded specifications
| Catalog identity | DDR5 ECC Registered DIMM (RDIMM) |
|---|---|
| Record type | DDR5 registered server module class |
| Verified specifications | 288-pin DDR5 RDIMM module class; DDR5 includes on-die ECC within DRAM devices, while ECC RDIMMs also carry system-level error-correction bits. Capacity, speed, rank, timing, and operating voltage are module- and platform-specific. |
| Compatibility | Requires a DDR5 RDIMM-capable server CPU and board. DDR5 RDIMM is not interchangeable with DDR5 UDIMM or SO-DIMM. Follow platform rules for CPU population, channels, ranks, and supported data rate. |
| 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 DDR5 RDIMM-capable server CPU and board. DDR5 RDIMM is not interchangeable with DDR5 UDIMM or SO-DIMM. Follow platform rules for CPU population, channels, ranks, and supported data rate.
- 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
Class-level entry, not a branded module. Clearly distinguish internal on-die ECC from host-visible ECC; verify error correction and reporting in platform diagnostics. Photograph both sides before cleaning; retain the host manual, SPD dump, test host, BIOS revision, and memory-test result with the catalog record.
