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.

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.
