32GB DDR4 ECC RDIMM for QNAP TS-h2490FU

This OWC module delivers 32GB of DDR4 3200 memory in a single 288-pin registered DIMM. It operates at 1.2V with CL22 latency and 2Rx4 organisation. The part is built for the QNAP TS-h2490FU and replaces QNAP part numbers RAM-32GDR4ECK0-RD-3200, RAM-32GDR4ECK1-RD-3200 and RAM-32GDR4ECT0-RD-3200.

Who should use this and who should not

This memory suits administrators upgrading or repairing a QNAP TS-h2490FU that requires ECC registered DDR4 RDIMMs. It will not work in standard desktop computers or any system that accepts only unbuffered non-ECC modules. Builders needing unbuffered memory or a different form factor must choose a different product.

The specification that decides fit

The module is a 288-pin DDR4 3200 ECC registered RDIMM with CL22 timing and 1.2V operation. Verify that the QNAP TS-h2490FU documentation calls for this exact registered ECC specification before purchasing.

Questions about this item

Is this 32GB module the only capacity available for the QNAP TS-h2490FU?

This listing is for a single 32GB DDR4 3200 PC4-25600 CL22 2Rx4 288-pin 1.2V ECC Registered RDIMM. Other capacities may exist but are not covered by this product.

What does the 3200 speed rating deliver in the TS-h2490FU?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency, providing the rated bandwidth and timing the QNAP TS-h2490FU expects for registered ECC memory.

Will the 288-pin DDR4 ECC registered interface work in a standard desktop?

No. This 288-pin DDR4 ECC Registered RDIMM is designed for workstation and server platforms like the QNAP TS-h2490FU and is not compatible with standard desktop computers that use unbuffered memory.
