OWC 4GB DDR3 1600 CL11 ECC UDIMM memory upgrade

SKU CH-VC4Y-GYZBF

A 4 GB DDR3 ECC UDIMM running at 1600 MHz with CL11 latency for compatible QNAP NAS models

  • Capacity4GB
  • Type240-Pin DDR3 ECC UDIMM
  • SpeedDDR3 1600 (PC3 12800)
  • CAS LatencyCL11
  • Voltage1.5V
  • ECCYes
  • ECC protection guards data integrity on supported QNAP systems
  • 1600 MHz DDR3 speed matches PC3-12800 spec for drop-in upgrades
  • Unbuffered 240-pin UDIMM fits TS-EC1080 PRO and TS-EC1280U series
  • Single 4 GB module keeps voltage at 1.5 V for stable operation
  • JEDEC and RoHS compliant build ensures warranty-safe installation

Compatible QNAP NAS upgrade

This 4 GB DDR3 ECC UDIMM is built for the QNAP TS-EC1080 PRO, TS-EC1280U, TS-EC1280U-RP, TS-EC1680U and TS-EC1680U-RP. It replaces the original QNAP part RAM-4GDR3EC-LD-1600 and carries JEDEC and RoHS compliance. The module is sold new and covered by a limited lifetime warranty with free technical support.

240-pin DDR3 slot requirement

Installation uses a single 240-pin unbuffered DDR3 DIMM slot running at 1.5 V. The 2Rx8 organisation fits the validated memory map of the listed QNAP systems without needing registered or buffered slots. Adding this module frees the existing memory channels for higher total capacity while keeping ECC protection active.

Sustained ECC operation at CL11

Rated at DDR3 1600 (PC3-12800) with CL11 latency, the module maintains error-correcting throughput during continuous file-serving and virtualisation workloads. The unbuffered design keeps latency predictable for the supported QNAP platforms. Buyers who need registered DIMMs or capacities beyond 4 GB per module cannot use this part.

Soalan tentang produk ini

Will the 1.5 V DDR3 1600 module throttle under sustained load?

DDR3 1600 at 1.5 V runs within JEDEC limits, so the module maintains rated speed without thermal throttling during continuous operation.

How much heat or noise does the unbuffered ECC UDIMM add to a QNAP TS-EC1280U running 24/7?

The module has no heat spreader and draws standard 1.5 V power, adding negligible heat and zero audible noise to the NAS enclosure.

Which QNAP models must I already own for this 240-pin 2Rx8 DIMM to work?

Compatible systems are TS-EC1080 PRO, TS-EC1280U, TS-EC1280U-RP, TS-EC1680U and TS-EC1680U-RP.
