64GB DDR4 2933MHz ECC RDIMM identity

This A-Tech module is a 64GB DDR4 2933MHz ECC registered DIMM built for server and workstation platforms. It operates at 1.20V with CL21 latency and uses a 2Rx4 organisation on a 288-pin interface.

Who should use this and who should not

The part suits administrators upgrading IBM-Lenovo systems that list part numbers 01KR356, 4X70V98063, 4X77A12186, 4ZC7A08710 or 4ZC7A08744. It is not for desktop boards that accept only unbuffered UDIMM memory, nor for laptops or small-form-factor units that require SO-DIMM modules.

Registered ECC 2Rx4 specification decides fit

The module presents a registered ECC 2Rx4 signal to the memory controller; the host platform must explicitly support registered ECC DIMMs and the 2Rx4 rank structure for the memory to initialise and run at the rated 2933MHz speed.

Preguntas sobre este artículo

How much power does the 64GB DDR4 2933MHz ECC RDIMM draw at its 1.20V operating voltage?

The module operates at the standard DDR4 voltage of 1.20V. Actual power draw depends on workload and server configuration, but registered ECC RDIMMs at this voltage are designed for efficient continuous operation in dense memory arrays.

What motherboard slot and memory channel configuration are required to install this 288-pin DDR4 RDIMM?

This module uses the standard DDR4 288-pin DIMM form factor and requires a registered DIMM (RDIMM) slot with ECC support. The server memory controller must support 2Rx4 rank organisation and DDR4-2933 speeds for full performance.

Will this 2933MHz CL21 RDIMM run at its rated speed alongside existing DDR4 RDIMMs in the same server?

When mixed with slower DDR4 RDIMMs, the memory controller typically downclocks all modules to the lowest common speed and loosens timings to maintain stability. For guaranteed 2933MHz operation, populate all channels with matched modules.
