Lenovo ThinkSystem compatible DDR4 RDIMM

This 8GB registered DIMM is built for Lenovo ThinkSystem servers that require DDR4 2933 ECC memory. It targets administrators upgrading Intel-based platforms where the 4ZC7A08706 part number is validated.

Fits 288-pin DDR4 RDIMM slots in qualified

The module operates at 1.2V with CL21 latency and a 1Rx8 organisation. ECC and register buffering protect data integrity while the single-rank design leaves additional slots free for further capacity expansion.

Sustained workloads benefit from ECC

Stress testing under load verifies stability for continuous server duties. The registered interface reduces electrical loading on the memory bus, helping maintain consistent throughput during extended operations.

Questions about this item

Will the CL21 latency become a bottleneck under sustained server workloads?

CL21 is the rated CAS latency for this DDR4 2933 module; sustained throughput depends on the platform memory controller and rank configuration.

How much heat does the 1.2 V registered ECC module produce during continuous operation?

The module runs at 1.20 V without a heat spreader; registered ECC RDIMMs typically stay cool in airflow-cooled server chassis.

Which Lenovo ThinkSystem models accept this 288-pin RDIMM for Intel-based servers?

It is listed as compatible with Lenovo ThinkSystem servers using part number 4ZC7A08706 for Intel processor platforms.
