QNAP TS-h2490FU 64GB DDR4 ECC RDIMM

This OWC module adds 64GB of DDR4 3200 ECC registered memory to the QNAP TS-h2490FU. It runs at 1.2V with CL22 latency and a 2Rx4 rank configuration on a 288-pin DIMM. The part replaces QNAP RAM-64GDR4ECK0-RD-3200 for a direct upgrade path.

Suits NAS admins expanding TS-h2490FU capacity.

Workstation and server boards that accept DDR4 ECC RDIMMs can use this module. Standard desktop motherboards cannot use registered ECC memory, and mixing it with unbuffered DIMMs will prevent boot. Buyers needing non-ECC or unbuffered memory for consumer platforms should look elsewhere.

64GB single-module capacity decides fit

The 64GB density per DIMM determines how many slots are needed to reach a target capacity. Verify the TS-h2490FU slot count and maximum supported memory per slot before purchasing. The 2Rx4 organisation and CL22 timing must match the system's memory controller requirements for stable operation.

Preguntas sobre este artículo

Will the 288-pin DDR4 DIMM fit the QNAP TS-h2490FU memory slots?

Yes, this 288-pin DDR4 3200 registered ECC module is built for the QNAP TS-h2490FU and matches the required form factor.

How do I install the 64GB DDR4 3200 CL22 registered ECC module, and what step is often missed?

Power down the NAS, open the chassis, seat the 288-pin DIMM firmly until the retention clips click, then verify in the QNAP firmware that all 64GB are recognised at 3200 MT/s.

What maintenance or replacement will the 64GB DDR4 3200 ECC registered DIMM need over time?

No routine maintenance is required; if a memory error appears, replace the module with an identical 64GB DDR4 3200 CL22 2Rx4 registered ECC DIMM to keep compatibility.
