QNAP NAS DDR4 2666 SODIMM

This 4 GB DDR4 module runs at 2666 MT/s with CL19 latency and 1.2 V operation. It is built as a 1Rx8 unbuffered non-ECC SODIMM using major OEM DRAM from Samsung Micron or Hynix. The part number MS21300-418K1 identifies the QNAP compatible series.

260-pin SODIMM slot requirement

The stick fits a single 260-pin DDR4 SODIMM slot in supported QNAP NAS units. No heat spreader is fitted so the low-profile design clears tight drive cages and chassis airflow paths. Installation follows the NAS owner’s manual and typically takes minutes.

Single module package content

The box contains one 4 GB DDR4 2666 SODIMM and nothing else. No extra cables brackets or software discs are included. The module is stress tested under load before shipping to verify stability in mission critical environments.

Questions about this item

What CAS latency does this module run at under continuous load?

The module operates at CL19 CAS latency, which remains constant during sustained use as it is a fixed timing parameter of the DDR4 2666 specification.

How much heat does this SODIMM generate when running all day in a NAS?

Without a heat spreader, the 1.20V DDR4 chips rely on case airflow; power draw stays at the standard DDR4 low-voltage level so additional cooling is rarely needed in a ventilated NAS chassis.

Which QNAP NAS models accept this 260-pin DDR4 SODIMM?

Compatibility is limited to QNAP systems that support DDR4 2666 unbuffered non-ECC SODIMMs; consult your NAS manual to confirm the slot type and maximum capacity before purchase.
