64 GB DDR5 ECC RDIMM for HPE servers

This 64 GB DDR5 4800 module is built as a single 2Rx4 registered DIMM with ECC for HPE server and workstation platforms. It targets administrators who need to expand memory capacity in compatible HPE systems using PC5-38400 registered memory. The module operates at 1.1 V with CL40 latency and uses major OEM chips from Samsung, Micron or Hynix.

Thermals noise and power draw

Registered DDR5 modules at 4800 MT/s draw modest power at 1.1 V and run without a heat spreader in typical server airflow. Passive cooling relies on chassis fans moving air across the 288-pin DIMM slots. Acoustic impact is negligible because the memory itself produces no noise. Power consumption scales with the number of populated slots and sustained bandwidth load.

Build quality connectors and daily use

The bare PCB design fits dense HPE motherboards where tall heat spreaders would block adjacent slots or cable routing. The 288-pin RDIMM keying prevents accidental insertion into non-ECC or unbuffered slots. Compatibility is validated against HPE part numbers P46970-H21, P58358-H21 and P62604-B21. Systems requiring mixed-rank populations or higher speeds should verify platform limits before adding this module.

Questions sur cet article

How do I install this 288-pin DDR5 RDIMM in my HPE server, and what step is commonly missed?

Power down the server, open the chassis, locate the correct memory channel slots for your CPU, align the module key with the slot, press firmly until both retention clips click, then verify in BIOS that the 64GB module is detected at 4800MT/s with ECC active.

What maintenance or replacement will this ECC RDIMM need over its service life?

The module has no heat spreader and no moving parts, so no routine maintenance is required; if a correctable error count rises or the server logs an uncorrectable ECC event, replace the DIMM under the lifetime replacement warranty.

What limit appears first when this 1.1V CL40 2Rx4 module runs sustained workloads?

The primary limit is the CL40 latency at 4800MT/s; sustained heavy traffic will saturate bandwidth before thermal throttling occurs because the module operates at 1.1V without a spreader.
