Server Memory Upgrade

This 16GB DDR4 2666MHz ECC RDIMM replaces Micron MTA36ASF2G72PZ-2G6B1, B2 and F1 modules in server and workstation systems. The registered design with 2Rx4 organisation and CL19 latency delivers 1.2V operation for data-intensive workloads.

Thermals and Power

Registered buffering reduces electrical load on the memory controller while ECC corrects single-bit errors without user intervention. Standard 1.20V DDR4 voltage keeps power draw predictable during sustained throughput.

Build Fit

The 288-pin DIMM installs in DDR4 RDIMM slots that support 2Rx4 registered modules. Verify your platform’s qualified-vendor list for Micron MTA36ASF2G72PZ-2G6B1 compatibility before purchase. Systems requiring unbuffered UDIMMs or different rank configurations cannot use this module.

Questions about this item

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

Align the notch on the module with the slot key, press down firmly until both side clips click shut, then verify in BIOS that the 2666 MHz speed and ECC function are recognised.

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

No routine maintenance is required; the module either continues operating at 1.20 V CL19 or is replaced if a memory test reports correctable errors exceeding the platform threshold.

What limit appears first when this 2Rx4 registered DIMM runs sustained workloads?

The registered buffer adds one cycle of latency, so the CL19 timing at 2666 MHz becomes the throughput ceiling before thermal or voltage limits are reached.
