16GB ECC SODIMM for Microservers and Workstations

This A-Tech module delivers 16GB of DDR4 2933 ECC memory in a 260-pin SO-DIMM form factor. It operates at 1.2V with CL21 latency and uses a 2Rx8 dual-rank layout. The unbuffered design suits compact servers, mobile workstations and NAS units that require error-correcting code memory.

Suits systems needing ECC SODIMM.

Builders upgrading Microservers, mobile workstations or NAS appliances that explicitly support DDR4 ECC unbuffered SO-DIMMs will benefit from the data-integrity feature. Buyers with standard consumer laptops or desktops that cannot use ECC modules should look at something else.

2Rx8 dual-rank organisation

The module is built as 2Rx8 dual-rank x8, which determines how the memory controller addresses the chips. Verify that your platform supports this rank configuration before purchasing, as some systems only accept single-rank modules.

Questions sur cet article

Does this 260-pin DDR4 ECC SODIMM need a laptop or microserver motherboard that specifically supports ECC unbuffered memory?

Yes. The module is an ECC unbuffered SODIMM, so the system must explicitly support ECC on its DDR4 SO-DIMM slots; otherwise the extra error-correction bits will not be used and the module may not post.

If I add this 2Rx8 dual-rank stick beside an existing single-rank 2933 MHz module, will both run at the rated 2933 MHz CL21?

The memory controller will train all populated slots to a common speed and timing; mixed-rank configurations usually still run at 2933 MHz CL21, but the final frequency depends on the platform's memory controller capabilities.

How can I confirm the module is detected as 16 GB ECC at 2933 MHz with CL21 timings after installation?

Check the BIOS/UEFI memory information screen or run a tool such as CPU-Z or dmidecode; it should report 16 GB, DDR4-2933, CL21, ECC enabled, and 2Rx8 dual-rank organisation.
