8GB DDR4 ECC SODIMM for Micron Microserver

This 8GB DDR4 2666MHz ECC SODIMM replaces the Micron MTA9ASF1G72HZ-2G6E2 module in microserver, server and workstation systems. The 260-pin unbuffered design operates at standard 1.2V DDR4 voltage with CL19 latency. It is built for owners who need error-correcting memory in a compact laptop form factor.

Thermals noise and power draw

Running at 1.20V, the module draws minimal power and produces negligible heat without a heat spreader. Passive cooling inside a typical microserver chassis is sufficient. Silent operation adds no audible noise to the system.

ECC unbuffered SODIMM requirement

This part is an ECC unbuffered SODIMM; systems that require registered or non-ECC memory will not accept it. Buyers who need non-ECC modules or higher capacities should verify their platform specifications before ordering.

Questions about this item

How do I install this 260-pin DDR4 SODIMM and what step do people often miss?

Align the notch on the module with the slot key, insert at a 30-degree angle, then press down firmly until both side clips click; the step many miss is pushing until both clips engage fully.

Will this ECC unbuffered module need any firmware updates or component replacements over time?

No firmware or component replacements are required; the module has no heat spreader and runs at standard 1.2V, so it operates maintenance-free for its service life.

At 2666 MHz CL19, what limit appears first during sustained heavy workloads?

The CAS latency of 19 cycles at 2666 MHz sets the primary latency floor; sustained throughput is bounded by the PC4-21300 data rate.
