[ REGISTERED ECC SERVER MODULE // MEMORY / RAM ]
Kingston Server Premier KSM26RD8/32MEI
Kingston Server Premier KSM26RD8/32MEI is a 32 GB DDR4-2666 registered ECC module with a dual-rank x8 device organization.
PART ID: KSM26RD8/32MEI. 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 KSM26RD8/32MEI |
|---|---|
| Module class | 288-pin DDR4 ECC Registered DIMM (RDIMM) |
| Capacity | 32 GB per module |
| Memory generation / data rate | DDR4-2666 (2666 MT/s; PC4-21300) |
| Error correction / buffering | System-level ECC module; registered/buffered command-address interface (RDIMM) |
| Rank / device organization | 2Rx8 (dual rank, x8 DRAM organization); 4G x 72 module organization using x8 DRAM devices |
| Timing / voltage | CL19 (19-19-19), 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 | For systems whose CPU, board and firmware support DDR4 ECC RDIMMs at 32 GB and 2Rx8 organization. The module is not interchangeable with DDR4 UDIMM or LRDIMM populations; consult the server manual and qualified-memory list. |
Platform compatibility & service notes
For systems whose CPU, board and firmware support DDR4 ECC RDIMMs at 32 GB and 2Rx8 organization. The module is not interchangeable with DDR4 UDIMM or LRDIMM populations; consult the server manual and qualified-memory list.
- 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.
