System-specific 32 GB DDR4 module

This 32 GB DDR4 LRDIMM is built for HP platforms that require ECC memory. It delivers 32 GB of capacity at 2400 MT/s with CL17 latency and operates at 1.20 V. The module targets administrators upgrading compatible HP servers or workstations where error correction is mandatory.

Fits 288-pin DDR4 slots with ECC support

The module uses the standard 288-pin DDR4 form factor and requires a platform that enables ECC functionality. It occupies a single DIMM slot and leaves remaining slots available for further expansion. Compatibility is limited to systems validated for this specific HP part number.

Runs at 1.20 V with standard DDR4 thermals

At the rated 1.20 V the module stays within normal DDR4 thermal limits during typical server workloads. ECC operation adds minimal overhead while protecting data integrity. Acoustic output depends on the host system’s cooling design rather than the module itself.

Questions about this item

Does the CL17 latency limit throughput under sustained workloads?

CL17 is the rated CAS latency at DDR4 2400; sustained throughput follows the PC4 19200 bandwidth ceiling of the module.

What heat or power impact should I expect when the 32 GB module runs continuously?

The module operates at 1.20 V DDR4 standard voltage; LRDIMM packaging helps manage thermal load during all-day operation.

Which existing hardware must I have for this 288-pin LRDIMM to function?

A compatible HP system with DDR4 2400 LRDIMM slots and ECC support is required for the 805353-B21-AX to work.
