OWC 8GB DDR4 3200 CL22 1Rx8 UDIMM memory upgrade for QNAP TS-877XU TS-877XU-RP TS-1277XU-RP TS-1677XU-RP

8GB DDR4 3200 UDIMM for QNAP NAS

This 8GB DDR4 3200 module is built as a direct memory upgrade for QNAP TS-877XU, TS-877XU-RP, TS-1277XU-RP and TS-1677XU-RP systems. It uses a 288-pin unbuffered UDIMM form factor and operates at 1.2V with CL22 latency. The single 1Rx8 rank module replaces QNAP part number RAM-8GDR4T0-UD-3200 and meets JEDEC specifications.

Suits owners of listed QNAP models adding capacity

Buyers with compatible QNAP NAS units can install this module to increase system memory for multitasking and larger workloads. The non-ECC unbuffered design matches the factory specification for these models. This module is not for systems that require ECC registered memory or a different DDR generation. It also does not suit builds needing speeds above 3200MHz or capacities beyond a single 8GB stick.

Check your NAS model and empty DIMM slots

Verify the exact model number on your QNAP chassis matches one of the four listed series before ordering. Confirm the motherboard has an available 288-pin DDR4 UDIMM slot and that the system BIOS supports 3200MHz operation with CL22 timing. The module is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz bus speeds if the platform runs at a lower frequency.
