HPE-compatible 64 GB DDR4 server memory

This module delivers 64 GB of DDR4-2666 capacity in a 288-pin load-reduced form factor with ECC. It runs at 1.20 V and carries the PC4-21300 speed rating. The 4Rx4 organisation suits dense memory configurations in HPE servers. It is built for administrators who need large-capacity registered DIMMs that match OEM specifications.

Sustained-load behaviour with load-reduced design

The load-reduced architecture lowers electrical load on the memory bus, helping signal integrity when all slots are populated. ECC corrects single-bit errors during continuous operation. Major-brand DRAM from Samsung, SK Hynix or Micron provides consistent timing at 2666 MT/s under prolonged workloads. The 1.2 V operation keeps power draw stable across extended duty cycles.

Straightforward installation

Each DIMM is 100 % tested and validated for HPE part number 815101-H21, so it seats in standard 288-pin DDR4 slots without configuration changes. Orders ship with identically matched modules to avoid rank or timing mismatches. The product is not suited for systems that require unbuffered UDIMMs or non-ECC memory. Buyers needing smaller capacities or different rank counts should select an alternative module.

Questions about this item

How much power does the 64GB DDR4-2666 4Rx4 Load Reduced module draw at its rated 1.20V?

Each module operates at 1.20 volts; total power draw scales with the number of modules installed and the server workload.

What server slot and memory type must the system already provide for this 288-pin DDR4 module?

The motherboard needs DDR4 RDIMM slots that accept 288-pin Load Reduced modules and support ECC.

Will this HPE-compatible 64GB DDR4-2666 module work in a server that currently runs HPE DDR4 RDIMMs at 2666 MT/s?

It is validated as 100 percent HPE compatible and runs at DDR4-2666, so it can populate empty slots alongside existing HPE DDR4-2666 RDIMMs.
