HPE-Compatible DDR4 ECC RDIMM

This 64 GB DDR4 2933 module is built for HPE servers and workstations that require registered ECC memory. The 2Rx4 organisation and CL21 timing match the P19045-B21 specification for reliable operation in multi-socket platforms. It targets administrators upgrading memory capacity in qualified HPE systems.

Single-Module 64 GB Upgrade

The package contains one 288-pin RDIMM delivering the full 64 GB in a single slot. This layout preserves remaining DIMM slots for future expansion while immediately adding maximum density per channel. No heat spreader is fitted, so airflow in dense server chassis is unaffected.

Registered ECC Build for 24/7 Workloads

Major-brand Samsung, Micron or Hynix DRAM chips operate at 1.20 V under registered control, reducing electrical load on the memory controller. The 288-pin RDIMM form factor locks into standard DDR4 server sockets, and the registered buffer helps maintain signal integrity across fully populated channels. Not suited for desktop boards that accept only unbuffered non-ECC DIMMs.

Questions about this item

Will the Samsung, Micron or Hynix chips on this 64 GB DDR4 module need replacement during the server's lifespan?

The module uses major OEM chips from Samsung, Micron or Hynix and carries a lifetime replacement warranty; no scheduled chip replacement is required.

What limit appears first when this CL21 2933 MT/s RDIMM runs sustained workloads?

CAS latency of 21 cycles at 2933 MT/s sets the first timing boundary before the PC4-23400 bandwidth ceiling is reached.

How much heat and power does a single 1.20 V 2Rx4 stick produce in 24/7 operation?

At 1.20 V the 64 GB registered DIMM draws minimal power and runs without a heat spreader, so thermal output stays low in continuous use.
