16GB DDR4-2933 ECC Registered module

This HPE SmartMemory module delivers 16GB of DDR4-2933 capacity with ECC and registered signalling. It targets administrators upgrading or repairing compatible HPE server and storage platforms. The 2Rx8 organisation suits mainstream dual-channel configurations. Buyers needing higher densities per slot or non-ECC unbuffered memory for workstations should look elsewhere.

Sustained 2933MHz operation at 1.20V

The module runs at PC4-23400 speeds with a CAS latency of 21 under continuous load. Registered buffering reduces electrical strain on the memory controller during prolonged throughput. ECC corrects single-bit errors in real time to maintain data integrity. Systems limited to lower DDR4 speeds will clock the module down automatically.

288-pin DIMM with major-brand DRAM

Each stick uses Samsung, SK Hynix or Micron components on a standard 288-pin DDR4 PCB. The registered design adds a buffer chip that occupies minimal height. Identical modules ship together to avoid mixed-rank populations. Builds requiring very low-profile heatsinks or proprietary form factors cannot use this DIMM.

Questions about this item

Does the 1.20V DDR4-2933 module draw noticeably more power or run hotter than lower-speed DDR4 when the server runs all day?

It operates at the standard DDR4 voltage of 1.20V, so power draw and heat are comparable to other DDR4 RDIMMs at this voltage.

Must the motherboard have 288-pin DDR4 slots that support ECC Registered memory for this 16GB stick to work?

Yes, the module is a 288-pin DDR4 RDIMM with ECC and requires a slot and chipset that accept registered ECC memory.

Can this 2Rx8 PC4-23400 RDIMM be mixed with 1Rx4 or 2Rx4 DDR4 registered modules in the same server?

Mixing ranks is often allowed but depends on the server's memory population rules; check the system manual for supported rank combinations per channel.
