256GB DDR5 RDIMM kit for Thinkmate servers

This 256GB kit contains four 64GB DDR5 4800 registered DIMMs built for Thinkmate HDX-XH24-52S4 high-density servers. ECC and registered buffering protect data integrity in mission-critical workloads. The modules operate at 1.1V with a CL40 latency profile.

Sustained load behaviour with ECC registered design

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC corrects single-bit errors on the fly to maintain stability under heavy multi-threaded tasks. The 2Rx4 organisation and major OEM chips from Samsung, Micron or Hynix support consistent throughput.

Verify DDR5 RDIMM slot count

Confirm the server motherboard provides four 288-pin DDR5 RDIMM slots and accepts 64GB 2Rx4 modules at 4800MT/s. Check the system qualified vendor list for part number MR38400-924K4 before ordering. No heat spreaders are fitted on these modules.

Questions about this item

Does the 1.10 V operating voltage keep the 4800 MHz kit cool under continuous server loads?

DDR5 modules run at 1.10 V, which reduces power draw compared with earlier generations; the 2Rx4 registered design also spreads the electrical load across ranks, helping thermal stability during all-day operation.

Must the ThinkMate HDX-XH24-52S4 already support DDR5 4800 registered ECC memory for this kit to function?

Yes — the modules are 288-pin DDR5 RDIMMs with ECC and registered buffering, so the host platform must provide a DDR5 RDIMM slot and chipset support for registered ECC operation.

Can the CL40 2Rx4 modules be mixed with other DDR5 4800 registered ECC DIMMs already installed in the same server?

Mixing is possible when all DIMMs share the same 4800 MT/s speed, CL40 latency, 1.10 V voltage, registered ECC type and 2Rx4 organisation; the memory controller will train to the common parameters.
