16 GB registered ECC DDR4-2933 module with 1Rx4 organisation runs at 1.20 V for HPE-compatible servers
This module is a 16GB DDR4-2933 registered ECC DIMM built for HPE servers. It runs at PC4-23400 speed with a 1Rx4 organisation and 1.20V operation. The 288-pin form factor fits standard DDR4 server slots. It targets administrators who need to expand memory capacity in supported HPE platforms without purchasing OEM-labelled kits.
Registered ECC modules operate at 1.20V, keeping power draw low inside dense chassis. Passive cooling is standard for this class of memory; no fan or active cooler is attached. The DRAM runs within JEDEC thermal limits during normal server workloads. Acoustic output is effectively zero because the module has no moving parts.
Each stick uses major-brand Samsung SK Hynix or Micron components and carries a lifetime warranty from the supplier. The 288-pin gold-edge connector seats firmly in DDR4 RDIMM slots with standard ejection levers. Modules are shipped in matched sets so every DIMM in an order carries identical specifications. Buyers who need unbuffered UDIMMs or non-ECC memory for workstation boards cannot use this registered ECC module.

Align the notch on the 288-pin DDR4 module with the slot key, press firmly until both retention clips click, then verify the server BIOS recognises the full 16GB at DDR4-2933.
Registered ECC DDR4 requires no scheduled maintenance; replace only if the server logs correctable errors that exceed the platform threshold or a module fails POST.
The 1Rx4 organisation and 1.20V operation cap sustained throughput at the rated DDR4-2933 speed; thermal throttling or voltage limits on the platform will trigger before the module itself.
