32GB DDR4 LRDIMM for servers

This 32GB DDR4 2400MHz PC4-19200 ECC LRDIMM module is built for server and workstation platforms that require registered, load-reduced memory. It delivers 32GB of capacity in a single 288-pin DIMM operating at 1.20V with CL17 latency. The Micron chipset base and 2Rx4 organisation suit high-density configurations where error correction and signal integrity are critical.

Replaces Micron MTA36ASF4G72LZ modules

The module is a compatible replacement for Micron part numbers MTA36ASF4G72LZ-2G3A1PG and MTA36ASF4G72LZ-2G3B1MG. The upgrade is worth it when your system board lists those Micron part numbers in its qualified vendor list and you need to expand memory capacity without changing voltage or speed parameters. It matches the original DDR4 2400MHz PC4-19200 specification and 1.2V operation exactly.

Verify LRDIMM support and slot population rules

Before ordering, confirm that your server or workstation motherboard supports DDR4 LRDIMM technology and 2Rx4 rank organisation at 2400MHz. Check the system documentation for maximum supported capacity per slot and any population guidelines that restrict mixing LRDIMMs with standard RDIMMs. The 288-pin form factor must match the DIMM sockets on your board.

Questions about this item

Will this 288-pin DDR4 LRDIMM fit my server's memory slots?

The module uses the standard 288-pin DDR4 DIMM form factor for load-reduced ECC memory. Verify your system supports LRDIMM before purchasing.

What is the correct way to seat this 2Rx4 ECC module during installation?

Align the notch with the slot key, press firmly until both retention clips click, and confirm the system detects the full 32GB capacity at 2400MHz.

When should I replace this 1.20V Micron-chipset module?

Replace if memory diagnostics report uncorrectable ECC errors, the server fails to POST with the module installed, or capacity drops below 32GB.
