ECC SODIMM for Microservers & NAS

This A-Tech 16GB DDR4 2666 ECC SODIMM adds error-correcting memory to compatible laptops, mobile workstations, microservers and NAS servers. The unbuffered 260-pin module runs at 1.2V with a CL19 latency. It targets users who need data integrity for critical workloads in compact systems.

Suits ECC-capable DDR4 platforms only

Buyers whose systems lack ECC SODIMM support in the BIOS or chipset cannot use this module. It is not for standard consumer laptops that accept only non-ECC memory. Builders needing higher capacities or different speeds should look at other modules.

The ECC unbuffered specification decides fit

Your platform must explicitly support DDR4 ECC Unbuffered SO-DIMM operation. Without that support the module will not function correctly. Verify the system manual for ECC SODIMM compatibility before purchase.

Questions about this item

Should I choose a single 16GB module or two 8GB modules?

This listing is a single 16GB module; adding a second identical stick enables dual-channel bandwidth on platforms that support it.

What does the 2666 MHz rating mean for everyday workloads?

The module runs at 2666 MHz with CL19 timing, delivering PC4-21300 bandwidth for faster load times and smoother multitasking in compatible systems.

How does the ECC unbuffered SODIMM interface affect compatibility?

It uses a 260-pin DDR4 ECC unbuffered SODIMM interface; the system must explicitly support ECC SODIMM modules for the error-correction feature to function.
