64GB DDR4 2933MHz ECC RDIMM

This 64GB DDR4 2933MHz ECC registered DIMM replaces Micron MTA36ASF8G72PZ-2G9B1, B2 and E1 modules. It runs at 1.2V with CL21 latency and a 2Rx4 rank layout. The 288-pin form factor fits standard server and workstation slots.

Servers needing registered ECC memory

Suits administrators upgrading compatible Micron-based servers or workstations that require registered ECC DDR4. Not for desktop boards that accept only unbuffered non-ECC DIMMs, nor for systems limited to lower capacities or slower speeds.

2Rx4 registered ECC configuration

The 2Rx4 registered ECC organisation determines whether the motherboard memory controller can address this module. Verify the platform's qualified vendor list for this exact rank and registration type before purchase.

Questions about this item

How much power does the 1.20V DDR4 2933MHz ECC RDIMM draw when the server runs continuously?

At the standard DDR4 voltage of 1.20V the 64GB registered module operates within normal server DIMM power limits; actual draw depends on workload and the platform's memory controller.

What must the motherboard provide for this 288-pin DDR4 RDIMM to function?

A DDR4 DIMM slot that supports ECC registered memory at 2933MHz (PC4-23400) with 2Rx4 organisation and 1.20V operation.

Will this CL21 2Rx4 module work alongside older DDR4 ECC RDIMMs of different speeds or ranks?

It will run at the lowest common speed and voltage supported by all installed DIMMs; mixing ranks or speeds is allowed but may reduce maximum bandwidth.
