32GB DDR5 4800 ECC RDIMM for THINKMATE SuperServer

This 32GB registered DDR5 module operates at 4800 MT/s with CL40 latency and 1.1V voltage. It uses a 1Rx4 organisation and 288-pin form factor. The module is validated for the THINKMATE SuperServer 521C-NR and built with major OEM DRAM chips. It targets administrators expanding memory capacity in compatible enterprise servers.

Registered ECC design runs at standard 1.1V

Registered buffering and on-die ECC maintain signal integrity and data accuracy under sustained workloads. The 1.1V operating voltage aligns with the DDR5 base specification for power efficiency. Absence of a heat spreader relies on server chassis airflow for thermal management during normal operation.

Replaces lower-capacity

The upgrade is worthwhile when the SuperServer 521C-NR requires additional registered ECC capacity for virtualisation, database or compute tasks. It is not suited for systems needing unbuffered memory, higher speeds than 4800 MT/s, or modules with integrated heat spreaders for restricted airflow environments.

Questions about this item

How do I install the 288-pin DDR5 RDIMM into the SuperServer 521C-NR, and what step is often missed?

Align the module notch with the slot key, press firmly until both side clips click, and ensure the registered buffer is fully seated; the step often missed is verifying the motherboard BIOS recognises the ECC registered configuration before booting the OS.

What maintenance or replacement will this 32GB 1Rx4 module need over its service life?

No routine maintenance is required; the module has no heat spreader and runs at 1.10V, so replacement is only necessary if a memory diagnostic reports uncorrectable ECC errors or the server workload exceeds the single 32GB capacity.

What limit appears first when the RDIMM runs sustained workloads at 4800 MT/s CL40?

The CAS latency of CL40 at 4800 MT/s sets the timing ceiling; sustained throughput is bounded by the 38400 MB/s data rate and the single-rank 1Rx4 organisation, so latency-sensitive tasks hit the CL40 wall before thermal or voltage limits.
