32GB DDR4 ECC LRDIMM Module

This 32GB DDR4 2666MHz ECC LRDIMM module uses a 2Rx4 organisation and runs at 1.20V with CL19 latency. It is built with major-brand chips on a 288-pin DIMM form factor for server and workstation platforms that require load-reduced registered memory.

Suited for servers needing Micron

This module matches the Micron MTA36ASF4G72LZ-2G6 and MTA36ASF4G72LZ-2G6D1 part numbers for direct replacement. Systems that do not support ECC LRDIMM technology or that require a different rank configuration will not be compatible with this memory.

Straightforward DIMM installation

Installation follows the usual 288-pin DIMM procedure: align the notch, press firmly until the retention clips engage, and verify seating. The most common issue is installing the module in a system that does not support load-reduced ECC memory, which prevents the system from posting.

Questions about this item

Does my server need to support DDR4 2666 MHz PC4-21300 ECC LRDIMM 2Rx4 modules for this 32GB stick to work?

Yes, the system must accept DDR4 2666 MHz PC4-21300 ECC LRDIMM 2Rx4 memory at 1.20V on a 288-pin DIMM slot.

Can I mix this 32GB DDR4 2666MHz ECC LRDIMM 2Rx4 module with existing Micron MTA36ASF4G72LZ-2G6 or MTA36ASF4G72LZ-2G6D1 sticks?

This module is a compatible equivalent for those Micron part numbers, so it can be used alongside them if the server supports mixed ranks and capacities.

How do I confirm the 32GB DDR4 2666MHz ECC LRDIMM 2Rx4 module is running at CL19 and 1.20V after installation?

Check the BIOS or UEFI memory information screen; it should report 32GB at 2666 MT/s, CL19 latency, 1.20V, and ECC LRDIMM 2Rx4 configuration.
