Server memory upgrade

This 64 GB DDR4 3200 RDIMM adds registered ECC capacity to compatible HPE servers and workstations. The single module installs in a standard 288-pin slot and operates at 1.2 V with CL22 timing. It targets administrators who need to expand memory in supported P06035-B21, P06035-H21 or P06035-K21 configurations. The 2Rx4 organisation suits high-density platform requirements.

Registered ECC design

Error-correcting code and registered buffering reduce data errors and electrical load on the memory bus. These traits are mandatory for the target HPE platforms and cannot be replaced by unbuffered desktop modules. The module ships alone in anti-static packaging with no additional cables, brackets or software utilities. Installation follows the host system service manual without extra steps.

Major-brand DRAM chips

The board uses Samsung, Micron or Hynix components selected for enterprise workloads. Absence of a heat spreader keeps the profile low for dense chassis layouts. Gold-edge 288-pin connectors ensure reliable contact through repeated thermal cycles. Build quality matches OEM qualification standards for continuous operation in rack environments.

Questions about this item

Will the 2Rx4 rank layout limit future DIMM population on my HPE server?

The module uses a 2Rx4 organisation; consult your server’s memory population rules to see how many ranks each channel accepts before adding more DIMMs.

Does CL22 latency become the bottleneck during sustained 3200 MT/s workloads?

At 3200 MT/s the CAS latency is 22 cycles; sustained throughput will be bounded by this timing and the memory controller’s scheduling efficiency.

How much heat does a 1.2 V registered DIMM produce when running continuously?

Operating at 1.2 V without a heat spreader, the module relies on chassis airflow; power draw stays within standard DDR4 RDIMM limits for 64 GB density.
