QNAP TS-h2490FU memory upgrade

This 16 GB DDR4 ECC registered DIMM is built for the QNAP TS-h2490FU server. It adds capacity to a system that requires registered modules with error correction. Standard desktop memory will not work in this platform.

Replaces QNAP RAM-16GDR4ECT0-RD-3200

The module matches the original part number and runs at DDR4 3200 with CL22 latency. The jump is worth it when the NAS is hitting memory limits during virtualisation or heavy file serving. Mixing with unbuffered DIMMs is not supported.

Verify registered ECC requirement

Confirm the TS-h2490FU currently uses registered ECC memory before ordering. The 288-pin form factor and 1.2 V operation must match the installed configuration. All slots should use identical capacity, speed and rank for best stability.

Klausimai apie šią prekę

Does the 288-pin DDR4 ECC RDIMM fit the QNAP TS-h2490FU memory slots?

Yes, the module is a 288-pin DDR4 3200 CL22 2Rx8 1.2V ECC Registered RDIMM built to replace QNAP part RAM-16GDR4ECT0-RD-3200 and installs directly into the TS-h2490FU DIMM sockets.

What is the correct installation sequence for this registered ECC module in the TS-h2490FU?

Power off the NAS, open the chassis, align the notch on the 288-pin RDIMM with the slot key, press firmly until the ejector clips lock, then power on and verify 16 GB appears in the system BIOS.

When should this 16 GB DDR4 3200 ECC RDIMM be replaced or upgraded?

Replace the module if memory diagnostics report correctable or uncorrectable ECC errors, if the NAS fails POST with beep codes indicating memory failure, or if workload growth requires higher total capacity.
