32GB DDR4 ECC RDIMM for QNAP NAS

This 32GB DDR4 2400 CL17 registered DIMM is built for QNAP TES-1885U, TES-3085U and TS-1685 systems. It delivers 288-pin ECC registered operation at 1.2V for server and workstation reliability. Buyers needing unbuffered memory for a standard desktop cannot use this module.

Sustained load behaviour with ECC registered design

The registered buffer and ECC circuitry correct single-bit errors and reduce electrical load on the memory controller during continuous operation. This helps maintain data integrity in multi-user NAS workloads such as virtualisation, database services and large file transfers over long periods.

Verify slot count and population rules before

Confirm your QNAP model has free 288-pin DDR4 RDIMM slots and check the manufacturer's population guide for rank mixing limits. This 2Rx4 module must not be mixed with unbuffered DIMMs and the total installed capacity must stay within the system's supported maximum.

Klausimai apie šią prekę

How much power does the 1.2V DDR4 2400 module draw when the NAS runs continuously?

The module operates at 1.2 volts, the standard DDR4 voltage, keeping power draw and heat low during all-day server workloads.

Does my QNAP TES-1885U already support ECC registered RDIMMs, or do I need a different motherboard?

The TES-1885U, TES-3085U and TS-1685 are designed for DDR4 ECC registered RDIMMs, so this 32 GB module fits the existing memory slots without hardware changes.

Can I add this 2Rx4 registered stick alongside the original unbuffered DIMMs in my TS-1685?

No, registered and unbuffered memory cannot be mixed; all slots must use ECC registered RDIMMs for the system to operate correctly.
