High-density DDR5 ECC kit

This kit supplies 1TB of registered DDR5 memory across sixteen 64GB modules for Lenovo ThinkStation PX workstations. Each module runs at 4800 MT/s with CL40 latency and 1.1V operation. ECC and 2Rx4 organisation protect data integrity in demanding server workloads. The 288-pin RDIMM form factor fits compatible DDR5 slots directly.

Build integration and slot planning

Sixteen modules occupy every available DIMM channel on supported ThinkStation PX boards, so no spare slots remain for later expansion. Registered buffering reduces electrical load on the memory controller, allowing the full population without signal degradation. ECC RDIMM topology requires a workstation or server platform that explicitly supports registered memory; consumer desktop boards will not post with this kit.

Thermals and power profile

Modules operate at the standard DDR5 voltage of 1.1V and have no integrated heat spreader, relying on chassis airflow for cooling. Registered buffers add minimal overhead, keeping power draw predictable across the full 1TB array. In typical workstation workloads the kit runs within normal DDR5 thermal limits when the system provides adequate front-to-rear airflow.

Questions about this item

Does the CL40 latency affect sustained throughput on this DDR5 4800 kit?

CL40 is the rated CAS latency at 4800 MT/s; sustained throughput depends on the workload and the Lenovo ThinkStation PX memory controller.

How much heat do the 16 modules generate at 1.10 V without spreaders?

Each 64 GB RDIMM runs at 1.10 V with no heat spreader; total thermal output scales with all 16 modules under continuous load.

Must the ThinkStation PX already have DDR5 RDIMM slots free for this 288-pin kit?

Yes — the kit uses 288-pin DDR5 RDIMM modules, so the workstation needs 16 available registered DIMM slots.
