OWC 4GB DDR4 2666 CL19 260-pin SODIMM for QNAP TS-1253DU-RP

SKU CH-FAKV-0YZJE

4GB DDR4 2666MHz CL19 SODIMM validated for QNAP TS-1253DU-RP NAS upgrades

  • Capacity4GB
  • Type260-Pin DDR4 Non-ECC SODIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.2V
  • ECCNo
  • 4GB DDR4 2666 CL19 SODIMM expands QNAP TS-1253DU-RP memory capacity
  • JEDEC-standard PC4-21300 module ensures warranty-safe NAS upgrade
  • Low 1.2V DDR4 voltage reduces system power draw
  • Backward compatible with 2400MHz and 2133MHz DDR4 speeds
  • 260-pin unbuffered non-ECC design fits QNAP TS-1253DU-RP slot

Targeted NAS Memory Upgrade

This OWC module is a 4GB DDR4 2666 SODIMM built specifically for the QNAP TS-1253DU-RP. It replaces the original QNAP part numbers RAM-4GDR4A0-SO-2666, RAM-4GDR4T0-SO-2666 and RAM-4GDR4T1-SO-2666. Buyers needing ECC error correction or higher capacity modules should look elsewhere.

Straightforward Slot Installation

The 260-pin SODIMM inserts directly into the NAS memory slot without tools. Because it is an unbuffered, non-ECC 1Rx8 design at 1.2V, it meets the JEDEC standard for the platform. Installers must ensure the system is fully powered down and disconnected before opening the chassis.

2666 MT/s Speed Rating

The decisive specification is the DDR4 2666 (PC4-21300) CL19 speed grade. The module is backward compatible with 2400 and 2133 MHz bus speeds if the system requires it. This exact speed rating determines whether the NAS will recognise and run the memory at its rated performance.
