Kingston Server Premier 32GB DDR4-3200 ECC Registered RDIMM Server Memory, CL22, 1Rx4 Hynix C-die

The Kingston Server Premier KSM32RS4/32HCR is a 32GB DDR4-3200 ECC Registered DIMM (RDIMM) with CL22 timings at 1.2V, built for rack and tower servers and workstations that take standard JEDEC DDR4 registered memory.

Server Premier is Kingston's industry-standard server line: modules are built on a controlled bill of materials with locked DRAM die revisions, and Kingston states the range is platform-validated with Intel and AMD and qualified with leading server and motherboard manufacturers. This part is a single rank 1Rx4 module on Hynix C-die 16Gbit DRAM with a Rambus register (RCD), and supports parity on the command/address bus. A single-rank module is the usual choice when you want one DIMM per channel at full 3200 MT/s speed.

• 1 × Kingston Server Premier 32GB DDR4-3200 ECC Registered DIMM (KSM32RS4/32HCR)
• Anti-static packaging — no heatspreader, screws or software

• Most Intel Xeon Scalable (2nd/3rd gen) and AMD EPYC 7002/7003 servers run DDR4-3200 RDIMMs; older platforms (for example Xeon v4 or 1st-gen Scalable) run them at their own lower maximum speed.
• For best bandwidth populate every memory channel of each CPU equally — typically 6 or 8 identical modules per processor.
• ECC corrects single-bit errors and registered buffering keeps large memory configurations stable, which is why servers and virtualisation hosts use RDIMMs.
• Because Server Premier locks the DRAM die, ordering more of the same part later gives modules built the same way — useful when expanding an existing host.

• Desktop PCs and consumer motherboards (non-ECC or UDIMM-only) — registered memory will not POST
• Servers populated with LRDIMMs or 3DS RDIMMs — do not mix module types
• DDR3 or DDR5 servers — different notch and pin layout
• Laptops and mini PCs that use SO-DIMMs
