64GB DDR4 ECC Registered module for servers

This 64GB DDR4 2933MHz ECC Registered RDIMM is built for workstations, servers and NAS systems that require registered memory with error correction. It operates at 1.2V with CL21 latency and a 2Rx4 rank configuration on a 288-pin form factor. The module is not compatible with standard desktop computers or unbuffered memory.

Sustained load behaviour with JEDEC compliance

The module meets JEDEC PC4-23400 specifications and maintains rated 2933MHz speed under continuous server workloads. ECC Registered design corrects single-bit errors and detects multi-bit errors to protect data integrity during extended operations. Backward compatibility allows operation at 2133MHz, 2400MHz and 2666MHz when the platform requires lower speeds.

Thermals and power in normal use

Operating at the standard 1.2V DDR4 voltage keeps power draw low during typical server and workstation use. The module has no heat spreader, relying on system airflow for cooling in chassis designed for registered DIMMs. ROHS compliant construction avoids hazardous substances while meeting industry thermal expectations for registered memory.

Preguntas sobre este artículo

How much power does the 1.2V DDR4 module draw when the server runs continuously?

At 1.2 volts the 64GB registered DIMM operates within standard DDR4 power limits, so sustained loads add only modest heat to the chassis airflow.

What motherboard slot and system type are required for this 288-pin ECC registered RDIMM?

You need a server, workstation or NAS board with a 288-pin DDR4 RDIMM slot that supports registered ECC memory; standard desktop boards will not accept it.

Will this 2933MHz CL21 module run stably in a system that currently uses 2133MHz, 2400MHz or 2666MHz DDR4 registered ECC DIMMs?

Yes, the module is backward compatible with 2133, 2400 and 2666MHz speeds and will clock down automatically while keeping ECC and registered operation.
