[ REGISTERED ECC SERVER MODULE // MEMORY / RAM ]
Kingston Server Premier KSM32RD4/64HCR
Kingston Server Premier KSM32RD4/64HCR is a 64 GB DDR4-3200 dual-rank x4 ECC Registered DIMM for platforms qualified for high-density RDIMMs.
PART ID: KSM32RD4/64HCR. This is a specific manufacturer module, not a generic DIMM standard. Verify full label, revision and SPD data on the specimen before using it for a service or compatibility decision.
Module specifications
| Manufacturer / part number | Kingston KSM32RD4/64HCR |
|---|---|
| Module class | 288-pin DDR4 ECC Registered DIMM (RDIMM) |
| Capacity | 64 GB per module |
| Memory generation / data rate | DDR4-3200 (3200 MT/s; PC4-25600) |
| Error correction / buffering | System-level ECC module; registered/buffered command-address interface (RDIMM) |
| Rank / device organization | 2Rx4 (dual rank, x4 DRAM organization); 8G x 72 module organization; x4 DRAM devices |
| Timing / voltage | CL22, per Kingston datasheet; nominal module voltage 1.2 V |
| Form factor | 288-pin DDR4 ECC Registered DIMM (RDIMM); contact count and keying are generation-specific |
| Compatibility | Use only where the platform specification/QVL permits 64 GB DDR4 ECC RDIMMs with 2Rx4 organization. Check CPU generation, BIOS, rank/density limits and population; the 3200 MT/s module rating does not guarantee that rate in a configured server. |
Platform compatibility & service notes
Use only where the platform specification/QVL permits 64 GB DDR4 ECC RDIMMs with 2Rx4 organization. Check CPU generation, BIOS, rank/density limits and population; the 3200 MT/s module rating does not guarantee that rate in a configured server.
- Match DDR generation, ECC and registered buffering independently; a mechanically similar UDIMM or LRDIMM is not interchangeable unless the host documentation explicitly allows it.
- Confirm CPU memory-controller capability, firmware, supported rank and DRAM density, maximum capacity per slot, and channel population rules in the server service manual and qualified-memory list.
- The printed transfer rate is a module rating. The configured rate can be lower because of the CPU, number of DIMMs per channel, ranks, firmware policy or other installed modules.
- Power down and follow the host service procedure. Use ESD precautions, handle by the edges and keep the original label and SPD record with the archived specimen.
Archival fields
Record the complete SKU, suffix and revision/date code; photograph both module sides; preserve SPD data, host model and CPU, BIOS/BMC version, socket/channel location, memory-test results and any ECC event counters. Reconfirm all traits against the physical sample because component revisions may vary.
