OWC 16GB DDR4 3200 ECC Registered RDIMM CL22 2Rx8 1.2V 288-pin

16GB ECC Registered DDR4 Module

This OWC 16GB DDR4 3200 ECC Registered RDIMM is built for QNAP NAS models including the TDS-h2489FU TVS-h474 TVS-h674 TVS-h874 and TS-1655. It delivers 16GB capacity at DDR4 3200 speed with CL22 latency and 1.2V operation. The 288-pin 2Rx8 registered design provides error correction for data integrity in server workloads.

Suited for QNAP NAS expansion; not for desktops

This module suits administrators upgrading the listed QNAP systems to increase memory capacity for virtualization or heavy file serving. It will not work in standard desktop computers or consumer motherboards because it requires registered ECC support. Builders needing unbuffered memory or non-ECC modules should look elsewhere as mixing registered with unbuffered memory is not supported.

Steady throughput under sustained server loads

Under continuous operation the registered buffer reduces electrical load on the memory controller helping maintain stable timings during long backup or virtualization tasks. ECC detection corrects single-bit errors on the fly preventing silent data corruption during extended uptime. The JEDEC compliant 1.2V DDR4 3200 specification ensures consistent bandwidth without thermal throttling in enclosed NAS chassis.
