4GB DDR4 2133MHz ECC RDIMM

This 4GB DDR4 2133MHz ECC RDIMM module is a compatible replacement for Micron MTA9ASF51272PZ-2G1A2II and MTA9ASF51272PZ-2G1B1 parts. It targets server and workstation systems requiring registered memory with error correction. The single-rank 1Rx8 configuration operates at 1.2V standard DDR4 voltage with CL15 latency. Buyers needing higher capacity per slot or non-ECC unbuffered memory for consumer platforms should look elsewhere.

Thermals noise and power draw

Registered DDR4 modules at 2133MHz draw modest power at 1.2V during typical server workloads. The ECC circuitry adds minimal overhead while providing data integrity for mission-critical applications. Passive cooling via chassis airflow is sufficient as these modules generate low heat under normal registered DIMM operation. No active cooling or special thermal management is required for standard deployment.

288-pin DDR4 DIMM form factor

The 288-pin DDR4 DIMM form factor fits standard DDR4 RDIMM slots in compatible server and workstation motherboards. Verify your system supports DDR4 2133MHz registered ECC memory before installation. The 1Rx8 organization allows flexible population across available memory channels. Systems requiring load-reduced DIMMs or different voltage specifications cannot use this module.

Questions about this item

How do I install this 288-pin DDR4 RDIMM and what step is often missed?

Power down the server, open the chassis, align the notch on the 288-pin DDR4 RDIMM with the slot key, press firmly until both retention clips click, then verify the module is seated evenly; the step often missed is ensuring both clips lock fully, as a partially seated stick will not post.

What maintenance or replacement will this 4GB ECC RDIMM need over time?

The module itself requires no scheduled maintenance; if a correctable ECC error count rises or the server logs uncorrectable errors, replace the stick — otherwise it runs for the life of the platform.

What limit appears first when this CL15 1.20V module runs sustained workloads?

The 4GB capacity is the first bottleneck; once the working set exceeds 4GB the system swaps to storage, so latency spikes before the 2133MHz speed or 1.20V thermal envelope become limiting factors.
