PHS-memory 16GB DDR4 ECC SO-DIMM 3200MHz PC4-25600E RAM para QNAP TS-432X-4G (SP554385)

16GB of ECC DDR4 memory running at 3200MHz with a peak transfer rate of 25.6GB/s — this PHS-memory module is the upgrade your QNAP TS-432X-4G has been waiting for. Built on a 260-pin SO-DIMM form factor and operating at just 1.2V, it delivers server-grade reliability in a compact, energy-efficient package. Whether you are running virtual machines, handling heavy file transfers, or supporting multiple users, this single 16GB stick ensures your NAS keeps pace without breaking a sweat.

Overview

The PHS-memory SP554385 is a 16GB DDR4 ECC SO-DIMM designed specifically for the QNAP TS-432X-4G NAS. It uses unbuffered ECC technology to detect and correct single-bit memory errors, preventing data corruption and system crashes. With a CAS latency of CL22 and JEDEC-compliant PC4-25600E specification, it delivers stable performance for 24/7 operation. The module is a single 16GB stick, leaving room for future expansion, and its low 1.2V voltage reduces heat and power consumption compared to older DDR3 modules.
