HPE ProLiant 32GB LRDIMM Upgrade

This 32GB DDR4 2666MHz module targets administrators expanding HPE ProLiant servers. It delivers ECC protection and load-reduced buffering for mission-critical workloads. The single-rank 2Rx4 organisation keeps electrical loading low on populated channels. New condition ensures factory-fresh reliability for production deployment.

288-Pin DDR4 Slot Integration

The 288-pin LRDIMM form factor installs directly into compatible HPE server memory slots without adapters. Load-reduced buffering reduces electrical load on the memory controller, freeing headroom for additional modules. 1.2V operation matches standard DDR4 server voltage rails. No heat spreader simplifies clearance in dense chassis configurations.

32GB Capacity with CL19 Latency

The 32GB density suits virtualisation hosts, database buffers and large dataset caching. CL19 timing at 2666MHz provides deterministic latency for consistent throughput. ECC corrects single-bit errors to maintain data integrity under sustained load. Builders needing higher per-slot density or faster speeds must evaluate alternative module specifications.

Questions about this item

Does the CL19 latency become a bottleneck during sustained server workloads?

The module runs at DDR4 2666 with CL19 timing; latency is fixed by the JEDEC specification and does not change under load.

How much heat does the 1.2 V LRDIMM generate when running continuously?

Operating at 1.20 V without a heat spreader, the module relies on server chassis airflow for cooling; power draw follows the DDR4 2666 standard.

Which HPE ProLiant models accept this 288-pin 2Rx4 ECC LRDIMM?

It is validated for HPE ProLiant servers that support DDR4 2666 PC4-21300 2Rx4 1.2 V ECC LRDIMMs; check the system memory guide for exact part-number matching.
