SK hynix 64GB DDR4 2666MHz ECC Registered CL19 LRDIMM Server Memory

SKU CH-RP58-5XCVG

A 64 GB DDR4 LRDIMM running at 2666 MHz with ECC and registered signal processing for servers and workstations

  • 64 GB capacity supports large server workloads
  • DDR4 2666 MHz speed enables fast data throughput
  • ECC registered design protects data integrity
  • Load-reduced DIMM lowers electrical load on memory bus
  • 20 V operation reduces power consumption

High-Capacity Server Memory

This single 64 GB DDR4 module uses Load-Reduced DIMM technology to deliver high density for server and workstation platforms. It operates at 2666 MHz with a CAS latency of CL19 and runs at a standard 1.20 V. The registered signal processing and ECC error checking maintain data integrity under sustained workloads.

Registered ECC with Load-Reduced Design

The registered buffer reduces electrical load on the memory controller, allowing larger memory configurations than standard unbuffered modules. ECC detects and corrects single-bit errors to prevent data corruption in critical applications. The 1.20 V operation matches the DDR4-2666/PC4-21300 standard for power-efficient performance in compatible systems.

288-Pin LRDIMM Form Factor

This module uses the 288-pin LRDIMM form factor with physical dimensions of 5.3" length, 1.2" width and 156.7 mil thickness. It weighs approximately 1.60 oz and carries RoHS environmental certification. Systems must support DDR4 LRDIMM memory at 2666 MHz with registered ECC to use this part.

Spurningar um þessa vöru

Will the 64GB LRDIMM need any firmware updates or component swaps during its service life?

No firmware or component swaps are required; the module is a sealed DDR4 LRDIMM with on-board ECC and registered signal processing that operates at 1.20 V for its entire service life.

What limit appears first when the module runs at 2666 MHz continuously in a fully populated server?

The thermal envelope of the 156.7 mil thick LRDIMM package becomes the limiting factor before the CL19 latency or 1.20 V supply can constrain sustained throughput.

How much heat and noise does the 64GB stick add when the system runs all day?

The single 1.60 oz module draws 1.20 V at 2666 MHz with no moving parts, so it adds only passive heat to the chassis airflow and generates no audible noise of its own.
