OWC 16GB DDR4 3200 ECC RDIMM

This 16GB DDR4 3200 registered DIMM adds error-correcting memory to the QNAP TS-h1290FX. It runs at PC4-25600 with CL22 latency at 1.2V. The 2Rx8 organisation and 288-pin form factor match the system requirements. Buyers needing unbuffered desktop memory cannot use this module.

Registered ECC constraints

Registered ECC RDIMMs require a motherboard and chipset that support buffered operation and error correction. The module will not function in standard desktop boards that accept only unbuffered memory. Mixing registered and unbuffered DIMMs in the same system prevents boot or causes instability. The JEDEC-standard DDR4 3200 interface defines the electrical and timing limits.

Verify QNAP TS-h1290FX compatibility

Confirm the NAS model is exactly TS-h1290FX before ordering. Check that all installed DIMMs share the same 16GB capacity, DDR4 3200 speed and registered ECC type for optimal performance. The part replaces QNAP RAM-16GDR4ECT0-RD-3200. Ensure the system has a free 288-pin DDR4 slot available.

Questions about this item

Should I pick a single 16GB module or add multiple sticks for the QNAP TS-h1290FX?

The module is a single 16GB stick; populate identical DIMMs per channel for best performance on the TS-h1290FX.

What does the 3200 speed rating deliver inside the TS-h1290FX?

The DDR4 3200 rating provides up to 25600 MB/s bandwidth when the system runs the memory at its rated frequency.

Will the 288-pin DDR4 ECC registered interface work with standard desktop boards?

No — the 288-pin registered ECC DIMM is designed for workstation and server platforms like the TS-h1290FX and is not compatible with unbuffered desktop memory slots.
