16GB DDR4 2400MHz ECC RDIMM 2Rx4 replacement for Micron MTA36ASF2G72PZ-2G3, MTA36ASF2G72PZ-2G3A3, MTA36ASF2G72PZ-2G3B1 server memory
This A-Tech module provides 16GB of DDR4 server memory at 2400MHz with ECC and registered buffering. It uses a 2Rx4 rank configuration and operates at 1.20V with CL17 latency. The 288-pin DIMM is built with major brand chips and serves as a compatible replacement for specific Micron part numbers.
This module fits systems that require DDR4 2400MHz registered DIMMs with error correction. It is not for desktop boards that accept only unbuffered non-ECC memory. Buyers who need a different speed, voltage, or rank layout should look at other modules.
Verify that your motherboard accepts 288-pin registered ECC DIMMs at 1.20V. Confirm the maximum capacity per slot and the supported memory speeds. Ensure the 2Rx4 organization matches your platform's requirements before ordering.

Yes, the module uses the standard 288-pin DDR4 DIMM form factor and requires a compatible registered DIMM slot on the motherboard.
No, registered RDIMMs and unbuffered UDIMMs cannot be mixed on the same platform; the memory controller must support registered modules.
Check the BIOS or UEFI memory information screen; it should report 2400 MT/s, CL17 timings, 1.20V, and show ECC enabled for the installed DIMM.
