32GB DDR3L ECC LRDIMM for HP 811221-001

This A-Tech server memory module delivers 32GB of DDR3L 1333MHz capacity in a single 240-pin LRDIMM. It is built for HP systems that specify part number 811221-001 and require ECC load-reduced registered memory. The 1.35V low-voltage design matches the DDR3L standard for compatible platforms.

Capacity and headroom for virtualised workloads

One 32GB module provides substantial memory headroom for multi-VM hosts, database buffers and large-file caching on supported DDR3L servers. The 4Rx4 organisation and CL9 latency suit throughput-oriented tasks. Systems limited to lower maximum module densities or non-LRDIMM slots cannot use this module.

Tested replacement with lifetime support

Each unit undergoes validation testing to confirm reliable operation as a direct equivalent for HP 811221-001. The package includes the single memory module only; no additional brackets, cables or software are supplied. US-based technical support is available for compatibility verification before installation.

Questions about this item

Will this 32GB DDR3L 1333MHz ECC LRDIMM work in a server that currently uses 1.5V DDR3 registered DIMMs?

This module runs at 1.35V and is a load-reduced DIMM. Mixing voltages or mixing LRDIMMs with standard registered DIMMs is not supported by most platforms; check your system manual before combining them.

How can I confirm the 32GB DDR3L 1333MHz ECC LRDIMM is running at the correct speed and voltage after installation?

Enter the BIOS or UEFI and verify the memory reports 1333 MT/s, 1.35V, ECC enabled, and LRDIMM mode. Server management tools such as iDRAC or iLO will also show the same details.

Does the 32GB DDR3L 1333MHz ECC LRDIMM 811221-001 ship as a single 240-pin module or a kit, and are any extra parts needed?

The box contains one 32GB 240-pin LRDIMM. No additional cables, brackets or cooling parts are required; the module installs directly into a compatible DDR3 DIMM slot.
