QNAP NAS memory upgrade

This 128GB kit contains four 32GB DDR4 2400 ECC registered DIMMs built for QNAP TES-1885U, TES-3085U and TS-1685 servers. It targets administrators who need the maximum supported capacity for virtualisation or heavy multi-user workloads.

Sustained load behaviour

ECC and registered signalling protect data integrity during continuous operation. The modules run at 1.2V with CL17 timing and will clock down automatically to match the installed processor, maintaining stability over long periods.

Installation notes

The 288-pin DIMMs fit the four memory sockets in the listed QNAP models. No heat spreaders are present, so airflow in the chassis must be adequate. Mixing with non-ECC or unbuffered memory is not supported by the platform.

Questions sur cet article

Does the 1.2 V DDR4 2400 registered ECC kit add noticeable heat or fan noise when the NAS runs 24/7?

The modules run at standard 1.2 V without a heat spreader; registered ECC DIMMs of this density typically add minimal thermal load, so existing NAS cooling handles continuous operation without extra noise.

What must the buyer already own for this 4 × 32 GB kit to work?

A QNAP TES-1885U, TES-3085U or TS-1685 NAS with four free 288-pin DDR4 slots and a processor that supports 128 GB maximum memory.

Will the CL17 2400 MHz sticks clock down automatically if the NAS CPU only supports lower speeds?

Yes, the memory will clock down to the optimal speed supported by the installed processor model.
