32GB DDR4 2666MHz ECC Registered RDIMM

This 32GB DDR4 module runs at 2666MHz with CL19 latency and 1.2V operation. It is an ECC Registered RDIMM built for servers, workstations and NAS systems. The 2Rx4 dual-rank organisation provides 32GB in a single 288-pin DIMM.

Fits Supermicro M11SDV motherboards

Validated for Supermicro M11SDV-4C-LN4F, M11SDV-4CT-LN4F, M11SDV-8C+-LN4F, M11SDV-8C-LN4F and M11SDV-8CT-LN4F boards. It replaces Supermicro part numbers MEM-DR432LC-ER26 and related MEMDR432L references. Registered ECC memory cannot be mixed with unbuffered DIMMs and will not work in standard desktop platforms.

Passive cooling with JEDEC voltage

No heat spreader is fitted; the module relies on chassis airflow at the standard 1.2V JEDEC voltage. Backward compatibility with 2133MHz and 2400MHz allows the DIMM to clock down when the platform requires lower speeds. Power draw stays within normal DDR4 Registered limits for dense server configurations.

Points forts

  • ECC registered design protects data integrity in servers
  • 32GB capacity expands memory for demanding workloads
  • DDR4 2666MHz speed matches Supermicro M11SDV motherboard specs
  • 2V operation reduces power draw versus higher-voltage modules
  • Backward compatible with 2133MHz and 2400MHz systems

Questions sur cet article

What is the CAS latency of this 2666MHz DDR4 ECC RDIMM under sustained server workloads?

The module operates at CL19 latency as specified for DDR4 2666 (PC4-21300) operation.

How much power does the 1.2V registered DIMM draw when running continuously in a Supermicro M11SDV system?

It runs at the standard DDR4 1.2V voltage; registered ECC modules typically draw slightly more power than unbuffered DIMMs due to the register.

Which motherboard models must I already have for this 32GB 2Rx4 module to work?

It is validated for Supermicro M11SDV-4C-LN4F, M11SDV-4CT-LN4F, M11SDV-8C+-LN4F, M11SDV-8C-LN4F and M11SDV-8CT-LN4F.
