SAMSUNG M386A8K40CM2-CTD 64GB DDR4-2666 LP ECC LRDIMM Memory

SKU CH-N4AE-39YW4

High-capacity 64GB DDR4-2666 LP ECC LRDIMM module for server memory expansion

  • 64 GB capacity supports memory-intensive server workloads
  • DDR4-2666 speed delivers high-bandwidth data throughput
  • Low-profile design fits space-constrained server chassis
  • ECC technology detects and corrects memory errors
  • Load-reduced DIMM architecture enables large-capacity configurations

Server-grade capacity

This 64 GB DDR4 module is built for enterprise servers and workstations that require very large memory footprints. The load-reduced ECC design supports data integrity under sustained workloads. It is not intended for consumer desktop or laptop platforms.

Thermals and power

Low-profile height helps airflow in dense chassis configurations. The DDR4-2666 rating delivers standard operating voltage for this class of memory. Error-correcting code operation adds minimal overhead while protecting against soft errors.

Build and installation

The LRDIMM form factor fits registered DIMM slots in qualified server mainboards. A 2666 MT/s data rate matches supported platform specifications. Buyers who need non-ECC unbuffered memory for consumer boards cannot use this module.

Questions about this item

How is the 64GB DDR4-2666 LP ECC LRDIMM installed in a server chassis?

Align the notch on the module with the key in the DDR4 slot, press down firmly until both retention clips click, and ensure the low-profile height clears any CPU cooler or airflow shroud.

What maintenance will the 64GB DDR4-2666 LP ECC LRDIMM require over its service life?

Periodically reseat the module to remove oxidation, verify ECC error counters in the BMC logs, and replace the DIMM if correctable errors exceed the platform threshold.

What thermal limit appears first when the 64GB DDR4-2666 LP ECC LRDIMM runs sustained workloads?

The module will throttle or trigger a platform alert once its case temperature exceeds the JEDEC-specified maximum for LP DDR4 LRDIMM operation.
