Server ECC LRDIMM Upgrade

This 64GB DDR4 module targets server and workstation administrators who need registered ECC memory with load-reduced buffering. It replaces the Hynix HMAA8GL7CPR4N-XN part and runs at 3200MHz with CL22 latency. The 1.20V operating voltage matches the DDR4 standard for compatible platforms.

Load-Reduced Buffering Benefit

The 4Rx4 LRDIMM architecture reduces electrical load on the memory controller, allowing higher density per channel than standard RDIMMs. ECC protection detects and corrects single-bit errors to maintain data integrity in mission-critical workloads. Major-brand chipsets underpin the module's validated reliability.

64GB Capacity Headroom

A single 64GB DIMM expands memory capacity for virtualization hosts, database servers and compute-intensive applications. The 3200MHz speed supports demanding throughput requirements within qualified systems. Builders needing higher total memory must populate additional slots with matching LRDIMM modules.

Highlights

  • 64 GB capacity handles heavy server workloads

Questions about this item

Will the 288-pin DDR4 LRDIMM need any firmware updates or periodic re-seating during its service life?

The module is a standard 288-pin DDR4 LRDIMM with no firmware; it requires no re-seating or software maintenance after correct installation.

What thermal or electrical limit is reached first when the 4Rx4 64GB module runs continuously at 3200 MT/s?

The 1.20 V operating voltage and CL22 timing define the electrical envelope; sustained loads stay within standard DDR4 thermal limits for load-reduced DIMMs.

How much heat and power does a single 64GB 1.2 V LRDIMM produce during all-day server workloads?

At 1.2 V the module draws typical DDR4 power for a 4Rx4 load-reduced DIMM, generating moderate heat that standard server airflow handles without extra cooling.
