HPE Server Compatible DDR4 RDIMM

This 32 GB registered ECC module runs at DDR4 2933 (PC4-23400) with CL21 latency and 1.2 V operation. It is built for HPE servers and workstations that require registered memory for stable multi-module configurations.

Sustained Workload Stability

The module uses major OEM Samsung, Micron or Hynix chips and is stress tested under load to maintain data integrity during continuous operation. ECC correction and registered buffering keep throughput consistent when the system runs at capacity for extended periods.

Thermals and Power in Normal Use

Operating at 1.20 V without a heat spreader, the 288-pin RDIMM draws minimal power and relies on chassis airflow for cooling. The low voltage and single-rank 1Rx4 organisation help keep temperatures and acoustic impact low in typical server deployments.

Questions about this item

How much heat or noise does this 1.2 V registered DDR4 module add when running continuously in a server?

The module operates at 1.20 V with no heat spreader, so it draws minimal power and adds no audible noise; system fans handle any warmth generated.

What must the server already provide for this 288-pin ECC RDIMM to function?

An HPE server with DDR4 RDIMM slots that support 2933 MT/s registered ECC memory and a memory controller able to address a 1Rx4 32 GB module.

Can this 2933 MHz CL21 stick share channels with slower DDR4 modules already installed in the same HPE system?

The server will clock all populated channels to the lowest common speed, so this module will run at the slower modules' rate while retaining ECC and registered operation.
