  • TypeRAM Module
  • 32 GB capacity supports large server workloads
  • DDR4 2133 MHz speed delivers reliable data throughput
  • ECC and registered design protects data integrity
  • 20 V operation reduces power draw per module
  • Compatible with Dell PowerEdge and Precision servers

32GB DDR4 LRDIMM for Dell Servers

This 32GB DDR4-2133 LRDIMM module delivers 32GB of ECC registered memory in a single 288-pin stick. It operates at 1.20V with CL15 latency and is validated for Dell PowerEdge and Precision servers. The load-reduced design helps maintain signal integrity on heavily populated channels.

Upgrade from standard RDIMM

When a server reaches the rank-per-channel limit of standard registered DIMMs, this LRDIMM allows higher total capacity without reducing memory speed. The jump is worth it for virtualization hosts or database nodes that need more memory ranks than RDIMM configurations permit.

32GB per module with DDR4-2133 bandwidth

Each module provides 32GB at 2133MHz, suitable for memory-intensive workloads such as large VM fleets or in-memory analytics. Capacity scales with available DIMM slots on supported platforms including PowerEdge M630, R630, R730, R730XD, T430, T630 and Precision R7910, T5810, T5810 XL, T7810, T7810 XL, T7910, T7910 XL. Systems requiring speeds beyond DDR4-2133 or non-ECC memory will not match this module's specifications.

Perguntas sobre este artigo

Will the 288-pin LRDIMM fit in a PowerEdge R730 memory slot?

Yes — the module uses the standard 288-pin LRDIMM form factor and is listed as compatible with the PowerEdge R730.

What is the correct way to seat this ECC registered module so the server recognises all 32 GB?

Align the notch with the slot key, press straight down until both retention clips click, then verify 2133 MHz operation in the BIOS.

When should the 1.20 V DDR4 LRDIMM be replaced to keep ECC protection reliable?

Replace it if the system logs show rising correctable error counts or if memory diagnostics report uncorrectable failures.
