NEMIX RAM 16GB DDR4 2666MHz CL19 2Rx8 1.2V 260-Pin SODIMM QNAP memory upgrade

SKU CH-N7P8-33XYD

16 GB DDR4 SODIMM running at 2666 MHz with CL19 latency for QNAP systems

  • Total capacity16 GB
  • Rated speedDDR4 2666 (PC4 21300)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL19
  • Buffer typeUnbuffered
  • Rated voltage1.2 V
  • Boosts QNAP NAS performance with 16GB DDR4 2666MHz memory
  • Low 1.2V voltage reduces power draw and heat output
  • CL19 latency timing supports responsive multitasking
  • 2Rx8 dual-rank design increases memory density per slot
  • 260-pin SODIMM form factor fits compatible QNAP laptop-style sockets

QNAP SODIMM upgrade

This 16 GB DDR4 SODIMM is built for QNAP systems that accept PC4-21300 memory. It targets owners who need a single-module capacity increase without mixing ranks. The 260-pin form factor fits compatible laptop-style slots in supported NAS units.

Sustained workload behaviour

CL19 timing and 1.2 V operation keep latency steady during long file transfers or virtualisation tasks. Dual-rank 2Rx8 organisation helps maintain throughput when multiple VMs or containers access memory simultaneously. Major-brand DRAM from Samsung, Micron or Hynix provides consistent output under continuous load.

Installation notes

Insert the module at an angle until the clips engage; no tools or firmware flashing are required. The lack of a heat spreader eases clearance in tight drive bays. Builders who need ECC protection or registered buffering cannot use this unbuffered non-ECC stick.

Questions about this item

How much power does the 1.2V DDR4 2666MHz SODIMM draw when the QNAP NAS runs continuously?

The module operates at the standard DDR4 voltage of 1.2V; actual power draw varies with the NAS workload and memory controller but stays within the DDR4 low-voltage envelope.

What must the QNAP NAS already provide for this 260-pin SODIMM to function?

The NAS needs a free 260-pin DDR4 SODIMM slot that accepts non-ECC unbuffered modules at 2666MHz (PC4-21300).

Will this CL19 2Rx8 module work alongside older DDR4 sticks already installed in the QNAP?

Yes, provided the existing memory is also DDR4 non-ECC unbuffered SODIMM; the system will run all modules at the lowest common speed and latency.
