32GB DDR4 ECC SODIMM for QNAP NAS

This 32GB DDR4 2666MHz module is built for QNAP NAS devices that require ECC unbuffered memory. It arrives as a single 260-pin SODIMM using major OEM chips from Samsung, Micron or Hynix. The stick runs at 1.2V with a CL19 latency and a 2Rx8 rank configuration. It targets administrators who need to expand memory in a compatible QNAP platform.

ECC unbuffered operation is the deciding spec

The module provides error-correcting code without registered buffering, matching the requirement of QNAP systems that specify ECC unbuffered SODIMMs. A non-ECC or registered alternative will not function correctly in those platforms. Verify that the target NAS lists DDR4 2666 ECC unbuffered support before purchase.

Fits a single SODIMM slot and leaves others free

Installation uses one 260-pin DDR4 slot, so any remaining slots stay available for further expansion up to the system limit. The low-profile design has no heat spreader, helping it clear tight drive cages or chassis lids. Ensure the NAS firmware recognises the 32GB density per slot before adding multiple units.

Questions about this item

Will the 2666MHz speed run at that rate in my QNAP NAS?

The module is rated DDR4 2666 (PC4-21300). It will operate at 2666MHz if the NAS memory controller supports that speed; otherwise it downclocks to the highest speed the controller allows.

Does the ECC unbuffered design work with standard QNAP SODIMM slots?

Yes. It is a 260-pin DDR4 ECC unbuffered SODIMM built to the PC4-21300 standard, matching the electrical and mechanical interface used by compatible QNAP systems.

Will the 32GB stick physically fit the SODIMM slot in my QNAP unit?

The module uses the standard 260-pin DDR4 SODIMM form factor with no heat spreader, so it fits the regular SODIMM socket found in supported QNAP NAS models.
