Green rectangular DDR4 LRDIMM module with black memory chips and gold edge connectors

Axiom

Axiom M4Z04AA-AX 64GB DDR4-2133 ECC LRDIMM server RAM

SKU CH-HX4Y-P2ZQP MPN M4Z04AA-AX

A 64 GB DDR4 server module running at 2133 MHz with ECC and LRDIMM architecture for data integrity and high-density capacity

  • Large 64 GB capacity supports memory-intensive workloads
  • ECC protection detects and corrects single-bit data errors
  • LRDIMM design reduces electrical load on the memory bus
  • DDR4-2133 speed delivers 2133 MHz data transfer rate
  • PC4-17000 rating matches 17000 MB/s peak bandwidth

64 GB DDR4-2133 ECC LRDIMM Server Module

This Axiom M4Z04AA-AX module delivers 64 GB of DDR4-2133 ECC registered memory in a single load-reduced DIMM. It is built for HP server platforms that require high-density registered memory with error correction. The PC4-17000 rating matches 2133 MHz operation for stable throughput in multi-socket systems.

Suits HP Servers Requiring High-Capacity

Administrators expanding memory in compatible HP servers will benefit from the 64 GB density and ECC protection. Builders needing unbuffered UDIMMs, non-ECC modules, or speeds above 2133 MHz should select a different part. The LRDIMM form factor also requires a platform that explicitly supports load-reduced registered memory.

Single 64 GB LRDIMM Determines Slot Planning

The module provides 64 GB in one physical slot, so maximum system capacity depends on the number of supported LRDIMM slots. Populating all channels with identical 64 GB modules ensures balanced performance and full ECC coverage across the memory subsystem.

Highlights

  • Large 64 GB capacity supports memory-intensive workloads
  • ECC protection detects and corrects single-bit data errors
  • LRDIMM design reduces electrical load on the memory bus
  • DDR4-2133 speed delivers 2133 MHz data transfer rate
  • PC4-17000 rating matches 17000 MB/s peak bandwidth

Questions about this item

Should I choose the single 64 GB module or combine multiple sticks to reach the same capacity?

This listing is a single 64 GB LRDIMM. If your server requires 64 GB in one slot, this module fits. For larger totals, add identical modules to matching slots following the platform's population rules.

What does the 2133 MHz rating deliver once the module is installed in a server?

The module runs at 2133 MHz, providing a PC4-17000 data rate. Actual throughput depends on the memory controller, channel count and BIOS settings of the host system.

How does the DDR4 LRDIMM interface and ECC feature affect usable performance?

The DDR4 LRDIMM design reduces electrical load on the memory bus, allowing higher densities per channel, while ECC detects and corrects single-bit errors to maintain data integrity.
