Server-grade ECC RDIMM for Micron systems

This 8 GB DDR4-2933 registered module carries ECC and a CL21 latency at 1.20 V. It is built for Micron-branded server and workstation boards that require registered DIMMs. The single-rank 1Rx8 organisation fits the MTA9ASF1G72PZ-2G9 specification.

288-pin registered design with no heat spreader

The bare PCB slides into standard DDR4 RDIMM slots and draws 1.20 V without extra clearance for a spreader. Registered signalling reduces electrical load on the memory controller, supporting stable operation in multi-module configurations. No additional cooling hardware is needed.

Replaces non-ECC or slower registered DIMMs

Upgrading from unbuffered non-ECC memory adds error correction for data integrity in critical workloads. Moving from lower-speed DDR4 RDIMMs raises bandwidth to PC4-23400. The jump is worth it when the platform demands registered ECC modules and the current population limits capacity or speed.

Questions about this item

What does the DDR4 2933 PC4-23400 rating mean for real-world throughput?

The module runs at 2933 MT/s with a peak bandwidth of PC4-23400; actual throughput depends on the server memory controller and channel population.

Will this 288-pin 1Rx8 RDIMM fit my Micron-compatible server board?

It uses the standard 288-pin DDR4 RDIMM form factor and 1Rx8 organisation, matching Micron MTA9ASF1G72PZ-2G9 specifications for registered DIMM slots.

How do I install this ECC registered module, and what step is often missed?

Power down, open the chassis, align the notch on the 288-pin edge connector, press firmly until the retention clips lock, then verify in BIOS that ECC and registered mode are enabled.
