Server-grade DDR4 module

This HPE SmartMemory module delivers 32GB of DDR4 capacity in a single registered DIMM. It is built for servers and workstations that require error-correcting memory for stable operation under continuous workloads.

Registered signal processing

The module uses registered signal processing with a CAS latency of CL21 and operates at 2933MHz conforming to the DDR4-2933/PC4-23466 standard. This specification determines compatibility with platforms that support registered DDR4 memory at this speed grade.

Sustained throughput stability

Registered buffering reduces electrical load on the memory controller, helping maintain consistent throughput during extended compute tasks. The 32GB density allows larger datasets to remain in memory, reducing swap activity during prolonged operations.

Questions about this item

What does 2933MHz mean for actual system speed?

The module runs at 2933 MT/s and conforms to the DDR4-2933/PC4-23466 standard.

What does the registered DDR4 interface do for me?

Registered signal processing places a register between the DRAM and the memory controller, reducing electrical load on the bus.

Will the 7.5-inch length and 750-mil thickness fit my server slot?

The module measures 7.5 inches long, 3.5 inches wide and 750 mil thick, matching the standard DDR4 RDIMM form factor.
