  • SpeedDDR4 2666 (PC4 21300)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.20V
  • 64 GB capacity expands server memory headroom
  • DDR4 2666 speed matches PC4-21300 bandwidth spec
  • ECC registered design protects data integrity under load
  • 20 V operation reduces power draw per module
  • 288-pin 4Rx4 form factor fits Supermicro MEM-DR464L-CL02-ER26 slot

SuperMicro-Compatible 64GB DDR4 RDIMM

This 64GB DDR4 2666 module is built for SuperMicro servers and workstations that require registered ECC memory. It targets IT professionals maintaining or expanding mission-critical systems where data integrity and stability are mandatory.

Single-Module Upgrade with Tested Reliability

The package contains one 64GB stick stress-tested under load to verify compatibility before shipment. No heat spreader is fitted, keeping the profile standard for dense server chassis where airflow spacing is tight.

DDR4 2666 Registered ECC Platform Limits

The DDR4 2666 registered ECC interface caps bandwidth at PC4-21300 and requires a motherboard that supports 4Rx4 organisation and 1.20V operation. Systems limited to lower speeds, unbuffered DIMMs or non-ECC memory cannot use this module.

Preguntas sobre este artículo

Will the 4Rx4 rank configuration require any specific motherboard slot population rules?

The module is a single 64 GB 4Rx4 DDR4 RDIMM; follow the Supermicro system manual for correct slot order and maximum rank-per-channel limits.

What thermal limit appears first when this registered ECC module runs continuously at 2666 MT/s?

The DRAM operates at 1.20 V with no heat spreader, so case temperature and airflow become the limiting factor before any throttling occurs.

How much power does the 288-pin RDIMM draw during all-day server workloads?

At 1.20 V the module stays within standard DDR4 RDIMM power envelopes; actual draw depends on workload intensity and system fan curves.
