Synology UC3200 memory kit

This 64 GB kit contains four 16 GB DDR4 2666 ECC UDIMM modules validated for the Synology UC3200 NAS. Each stick runs at 1.2 V with CL19 latency and uses a 2Rx8 organisation for stable server workloads.

288-pin unbuffered ECC installation

The modules fit standard 288-pin DDR4 slots and require no registered buffer, so they install directly into the UC3200 memory bays. ECC protection corrects single-bit errors, freeing the system from silent data corruption during heavy file serving.

Low-voltage thermal profile

Operating at 1.20 V keeps power draw modest and heat output low inside the compact NAS chassis. Without heat spreaders the modules rely on system airflow, which the UC3200 design provides for quiet, continuous operation.

Perguntas sobre este artigo

Will the 1.2 V DDR4 2666 CL19 modules hit any thermal limit during continuous operation in the Synology UC3200?

The modules run at 1.2 V without a heat spreader; the UC3200 chassis airflow is designed for standard JEDEC UDIMMs at this voltage.

How much noise, heat or extra power do the four 16 GB sticks add when the NAS runs all day?

Each stick draws 1.2 V at DDR4 2666 with CL19 timing; total power is low and the UC3200 fan curve does not change under normal load.

What must the Synology UC3200 already have so this 288‑pin ECC UDIMM kit works?

The UC3200 must support DDR4 2666 ECC unbuffered UDIMMs and provide four free 288‑pin slots.
