16GB ECC RDIMM for servers

This 16GB DDR4 3200MHz registered DIMM delivers error-correcting memory for server and workstation platforms. It uses a 1Rx4 organisation with major-brand chips and runs at the standard 1.20V. The module is a direct replacement for Micron MTA18ASF2G72PZ-3G2 and MTA9ASF2G72PZ-3G2 parts.

Thermals noise and power

Operating at 1.20V, the RDIMM draws minimal power and generates little heat inside a server chassis. Registered buffering reduces electrical load on the memory controller, helping overall system stability. No active cooling is required on the module itself.

Upgrade path and fit

This module replaces failed or lower-capacity DDR4 ECC RDIMMs in compatible 288-pin slots. The jump is worthwhile when ECC protection and registered signalling are required for data integrity. Systems limited to unbuffered UDIMMs or non-ECC memory cannot use this module.

Questions about this item

How do I install this 288-pin DDR4 RDIMM and what step is often missed?

Power off the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both side clips lock, then verify in BIOS that the 3200 MHz speed and ECC are recognised — skipping the BIOS check is the common oversight.

What maintenance or replacement will this 16GB ECC module need over time?

No routine maintenance is required; the module either passes POST or it fails, in which case the lifetime warranty covers a replacement unit.

What limit appears first when this CL22 1.20V registered DIMM runs sustained workloads?

The CAS latency of 22 cycles at 3200 MHz sets the response-time floor, so latency-sensitive tasks hit that timing ceiling before bandwidth or thermal limits become an issue.
