Server Memory Upgrade

This 32GB DDR4 2666MHz ECC RDIMM module is built for servers and workstations that require registered memory with error correction. It replaces Micron part numbers MTA36ASF4G72PZ-2G6, MTA36ASF4G72PZ-2G6B2 and MTA36ASF4G72PZ-2G6D1. The module uses major-brand chips and runs at the standard 1.20V voltage.

DDR4 2666 Registered Limits

The DDR4 2666 interface operates at PC4-21300 speed with CL19 latency. Registered DIMMs add a buffer that reduces electrical load on the memory controller, allowing higher capacities per channel than unbuffered modules. This module is a 2Rx4 dual-rank design using 288-pin DIMM form factor. Systems that only accept unbuffered UDIMMs cannot use this registered module.

Compatibility Check List

Verify that your motherboard or server platform supports DDR4 ECC RDIMM memory and accepts 32GB dual-rank modules. Confirm the maximum supported memory speed and total capacity per slot in the system documentation. Ensure the BIOS is updated to a version that recognises this module density. Buyers who need unbuffered memory or a different rank configuration should select an alternative module.

Questions about this item

How do I pick the right capacity for my server?

This module provides 32GB in a single 288-pin DDR4 RDIMM, so add one per available slot to reach your target total.

What does DDR4 2666 mean for real-world throughput?

The module runs at 2666 MT/s with CL19 latency, giving server workloads the rated DDR4 2666 bandwidth at 1.20V.

Will the registered ECC interface work with my platform?

It is a 2Rx4 registered ECC DDR4 DIMM; the memory controller must support registered ECC DDR4 for the module to function.
