  • CAS LatencyCL17
  • Voltage1.2V
  • ECCNo
  • 8GB capacity expands NAS multitasking headroom
  • DDR4 2400 CL17 speed matches QNAP specs
  • 2V low voltage reduces system power draw
  • 288-pin UDIMM fits TS-1677X and TS-432 series
  • JEDEC compliant ensures warranty-safe upgrade

QNAP-Validated DDR4 Upgrade

This 8 GB DDR4 module is built for the QNAP TS-1677X, TS-432XU, TS-432XU-RP, TS-432PXU and TS-432PXU-RP NAS platforms. It replaces OEM part numbers RAM-8GDR4A0-UD-2400 and RAM-8GDR4A1-UD-2400 directly. The non-ECC unbuffered design matches the factory memory specification for these systems.

JEDEC-Standard 288-Pin UDIMM

The stick uses a standard 288-pin DDR4 UDIMM form factor with no heat spreader, fitting the slim DIMM slots found in the listed QNAP units. Gold-edge contacts meet JEDEC and RoHS requirements for reliable seating. Installation is a tool-free DIY task that does not void the appliance warranty.

Single-Rank CL17 at 2400 MT/s

Rated at PC4-19200 with CAS latency 17, the module runs at 1.2 V and is backward compatible with 2133 MHz operation. The 1Rx8 organisation delivers 8 GB per slot, so total capacity depends on how many slots your specific NAS model provides. Buyers needing ECC error correction or registered buffering should choose a different module.
