32GB DDR4 ECC UDIMM for QNAP NAS

This 32GB DDR4 3200 CL22 ECC unbuffered UDIMM is built for QNAP TS-h1887XU, TS-h2287XU, TS-h3087XU, TS-h3088XU-RP and TS-h987XU systems. It runs at 1.2V with a 2Rx8 rank configuration and meets JEDEC standards. The module replaces QNAP part numbers RAM-32GDR4ECK0-UD-3200 and RAM-32GDR4ECT0-UD-3200.

Who this suits and who it does not

It fits administrators expanding memory in the listed QNAP rackmount NAS units where ECC unbuffered DDR4 is required. Buyers needing non-ECC memory, registered DIMMs, or capacities other than 32GB per module should look at different parts. Systems that do not accept 288-pin DDR4 UDIMMs cannot use this upgrade.

Deciding specification — 288-pin DDR4 ECC unbuffered

The single detail that determines compatibility is the 288-pin DDR4 ECC unbuffered form factor at 3200MHz CL22. Verify the target NAS requires exactly this module type and speed grade before ordering. The 2Rx8 organisation and 1.2V operation must match the system memory specification.

Questions about this item

Will this 32GB DDR4 3200 ECC UDIMM work in my QNAP TS-h1887XU?

Yes, the module is validated for QNAP TS-h1887XU, TS-h2287XU, TS-h3087XU, TS-h3088XU-RP and TS-h987XU and replaces QNAP part numbers RAM-32GDR4ECK0-UD-3200 and RAM-32GDR4ECT0-UD-3200.

Can I mix this CL22 3200MHz stick with my existing 2666MHz ECC DIMMs?

The module is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz speeds, so it will run at the lower frequency of the installed DIMMs while maintaining ECC operation.

How do I verify the 32GB module is detected at 3200MHz with ECC active after installation?

Check the QNAP system information or resource monitor; it should report 32GB total capacity, DDR4 3200 speed, and ECC enabled for the new DIMM slot.
