16GB DDR4 ECC RDIMM for Servers

This module delivers 16GB of DDR4 2933MHz registered ECC memory for server and workstation platforms. It operates at 1.20V with CL21 latency and uses a 2Rx8 organisation. The 288-pin DIMM is built as a compatible replacement for Micron MTA18ASF2G72PDZ-2G9E1 and MTA18ASF2G72PDZ-2G9J3 part numbers.

Registered DIMM limits and platform rules

Registered ECC RDIMMs place an electrical load on the memory controller that unbuffered modules do not. The platform must explicitly support registered ECC memory; consumer desktop chipsets and many laptop sockets will not initialise this module. Mixing registered with unbuffered DIMMs in the same channel is not supported by any DDR4 platform.

Verify memory controller and slot layout

Confirm that your system board or processor memory controller lists DDR4 2933MHz registered ECC RDIMM support and provides 288-pin DIMM slots. Check the maximum per-slot capacity and total channel population limits in the vendor documentation before ordering. The module uses Micron chipset components and follows the PC4-23400 standard.

Questions about this item

Should I choose the 16GB module or a different capacity for my server upgrade?

This listing is for a single 16GB DDR4 2933MHz ECC RDIMM. Select this module when your system requires exactly 16GB per slot or when populating empty DIMM slots in 16GB increments.

What does the 2933MHz speed mean for actual server workloads?

The module runs at 2933 MT/s with CL21 latency and 1.20V, delivering the standard DDR4-2933 data rate for compatible server and workstation platforms.

How does the PC4-23400 rating and registered ECC design affect compatibility?

PC4-23400 is the industry designation for DDR4-2933 bandwidth. The 2Rx8 registered ECC DIMM uses 288 pins and requires a platform that supports registered memory with error correction.
