8GB DDR4 ECC RDIMM for Micron Server Upgrade

This 8GB DDR4 2666MHz ECC registered DIMM is built for servers and workstations that require error-correcting memory. It serves as a direct replacement for Micron MTA9ASF1G72PZ-2G6 modules. The single-rank 1Rx8 design uses major-brand chips tested for dependable operation in enterprise environments.

Fits 288-pin DDR4 slots with registered buffer

The module plugs into standard DDR4 DIMM sockets and operates at the standard 1.2V voltage. Its registered buffer reduces electrical load on the memory controller, freeing headroom for larger memory populations. Buyers must confirm their platform supports ECC RDIMMs; systems limited to unbuffered non-ECC memory cannot use this module.

Replaces Micron MTA9ASF1G72PZ-2G6

This unit matches the 8GB capacity, 2666MHz speed, CL19 latency and 1Rx8 organisation of the original Micron parts. The upgrade is worthwhile when expanding total memory or swapping failed sticks in qualified servers. It does not suit builds needing higher frequencies, different ranks or non-ECC unbuffered DIMMs.

Questions about this item

How many ranks does the 1Rx8 organisation present to the memory controller?

The module is single-rank, so the controller sees one rank per DIMM.

What is the typical power draw of this 1.20 V DDR4 RDIMM under continuous server workloads?

At 1.20 V the module runs at standard DDR4 voltage, keeping power and heat low during all-day operation.

Which motherboard slot and chipset combination is required to run this 288-pin registered ECC DIMM?

A DDR4 RDIMM slot with a server-class chipset that supports registered ECC memory is needed.
