OWC DDR4 3200 for QNAP NAS

This 16 GB DDR4 module is built for QNAP TS-877XU, TS-877XU-RP, TS-1277XU-RP and TS-1677XU-RP systems. It delivers a straight-forward capacity increase for NAS units that need more memory for virtualization, caching or heavy multi-user workloads.

288-pin UDIMM CL22 at 1.2 V

The single specification that decides fit is the 288-pin unbuffered non-ECC UDIMM form factor running at CL22 latency and 1.2 V. Only systems accepting this exact electrical and physical profile will recognise the module.

16 GB headroom with 3200 MT/s backward compatibility

The 16 GB stick handles demanding NAS services and multiple containers comfortably while the DDR4 3200 rating also covers 2933, 2666, 2400 and 2133 MT/s buses. It reaches its limit when the chassis slots are full or the workload demands ECC protection.

Questions about this item

What does the 3200 MHz rating actually deliver in a QNAP TS-877XU?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency, providing the rated bandwidth when the NAS memory controller supports that speed.

Which DDR4 standard and pin layout does this UDIMM use?

It is a 288-pin unbuffered non-ECC DDR4 UDIMM built to JEDEC PC4-25600 specifications.

Will the 2Rx8 288-pin stick fit the memory slots in a TS-1677XU-RP?

Yes, the 288-pin UDIMM form factor matches the DIMM slots used in the listed QNAP TS-x77XU series.
