32 GB DDR4 LRDIMM for HPE Z840

This 32 GB DDR4 2666 MHz load-reduced ECC module is built for the HPE Z840 server platform. It targets IT teams that need registered memory with error correction for mission-critical workloads.

Thermals and power in daily use

The module runs at 1.2 V without a heat spreader, relying on chassis airflow for cooling. Load-reduced buffering reduces electrical load on the memory controller, helping keep system power draw stable under sustained demand.

Build and slot implications

A 288-pin LRDIMM form factor fits DDR4 server slots that support load-reduced memory. The 2Rx4 organisation and CL19 latency suit high-capacity configurations, but the module will not work in consumer desktop boards or unbuffered channels.

Points forts

  • 32 GB capacity expands server memory headroom
  • DDR4 2666 speed delivers high data throughput
  • ECC LRDIMM technology protects data integrity
  • 2Rx4 rank organisation optimises signal loading
  • 2 V operation reduces power consumption

Questions sur cet article

How do I install the 288-pin DDR4 LRDIMM in my HPE Z840 server, and which step do people often get wrong?

Align the notch on the module with the slot key, press straight down until both retention clips click, and verify the 2Rx4 rank appears in BIOS; the step often missed is seating the module fully so both clips engage at once.

What maintenance or replacement will the 32GB ECC LRDIMM need during its service life?

No scheduled maintenance is required; ECC corrects single-bit errors on the fly, and the module should only be replaced if the server logs uncorrectable memory errors or a DIMM health alert.

What limit appears first when the 2666 MHz CL19 LRDIMM runs sustained workloads?

The CAS latency of CL19 at 2666 MT/s sets the timing ceiling; sustained throughput will be bound by that latency before thermal or voltage limits are reached.
