64GB DDR4 2933 ECC LRDIMM module

This 64GB DDR4 2933 ECC LRDIMM module provides high-density server memory for HP platforms. It targets administrators upgrading compatible workstations or servers that require registered load-reduced DIMMs. The single-module design simplifies capacity scaling in qualified systems.

288-pin DIMM with major-brand chips

The 288-pin form factor fits standard DDR4 server slots and operates at 1.20V. Major-brand chips and CL21 latency support reliable operation under sustained workloads. Load-reduced buffering reduces electrical load on the memory controller, enabling higher capacities per channel.

Lifetime warranty with US-based support

A lifetime warranty covers the module against defects, and US-based technical support is available before and after purchase. Rigorous quality-assurance testing validates each unit for dependable performance. Buyers must verify their system's supported memory specifications to ensure compatibility.

Questions about this item

What DDR4 standard does this 2933MHz module follow and what bandwidth does it provide?

This module follows the DDR4 PC4-23400 standard, delivering 23400 MB/s peak transfer rate at 2933MHz with CL21 latency.

What physical slot and pin count does this 64GB LRDIMM require?

It requires a standard DDR4 DIMM slot with 288 pins; the load-reduced design fits the same socket as regular DDR4 DIMMs.

How is this ECC LRDIMM installed and what common step is missed?

Align the notch with the slot key, press firmly until both side clips click; the step often missed is verifying the motherboard supports LRDIMM and 4Rx4 rank configuration.
