16GB DDR4 ECC RDIMM for Servers

This 16GB DDR4 2400 registered DIMM adds ECC-protected capacity to compatible server and workstation platforms. It operates at the standard 1.20V DDR4 voltage with CL17 latency and a 2Rx4 rank organisation. The module is a tested replacement for Micron part numbers MTA36ASF2G72PZ-2G3B1QI and MTA36ASF2G72PZ-2G3A3IK.

Registered ECC with 2Rx4 Organisation

The registered buffer and on-die ECC are the defining specification for data-integrity workloads. The 2Rx4 configuration delivers 16GB in a single 288-pin DIMM running at PC4-19200 speed. Systems that require unbuffered non-ECC UDIMMs or a different rank layout will not accept this module.

Fits DDR4 RDIMM Slots Requiring Micron Compatibility

Installation requires a motherboard with DDR4 RDIMM slots that support 2400MHz registered ECC memory and the specific Micron chipset equivalence. The single-module design leaves remaining slots free for further capacity expansion. Builders needing unbuffered memory, non-ECC operation, or a different speed grade should select an alternative part.

Questions about this item

How does the 2400 MHz speed translate to real throughput in a server?

DDR4 2400 runs at PC4-19200, giving a peak transfer rate of 19200 MB/s that the memory controller can sustain under load.

What does the PC4-19200 rating limit in practice?

PC4-19200 sets the maximum data rate at 19200 MB/s; the registered design adds one clock cycle of latency but keeps signal integrity at full speed.

Will the 288-pin DDR4 DIMM fit my server board?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor and 1.20 V operation required by registered server platforms.
