Synology SA3200D memory kit

This 64 GB kit contains four 16 GB DDR4 2666 ECC UDIMM modules built for the Synology RackStation SA3200D. It targets administrators who need to expand NAS memory for virtualization, heavy file serving or surveillance workloads. The ECC unbuffered design matches the system's native requirements.

Straightforward DIMM installation

The 288-pin UDIMMs seat in the SA3200D's standard slots without tools; the kit is validated for that model so no firmware update is required. The only common issue is mixing these CL19 2Rx8 sticks with existing modules of different rank or latency, which can prevent the system from posting.

Verify slot count and current population

Confirm the SA3200D has four free DIMM slots or plan to replace all installed memory, because the kit must run as a matched set of four. Check that the chassis airflow reaches the bare modules, as they ship without heat spreaders. Ensure the NAS firmware is current before adding capacity.

Perguntas sobre este artigo

How can I verify the 64GB kit is running at 2666MHz with ECC after installation?

Check the Synology DSM Resource Monitor or BIOS memory details; they should show 64GB total, 2666MHz speed, CL19 timings, 1.2V voltage and ECC active for each 16GB module.

What ships in the box and is anything else required?

The package contains four 16GB 288-pin DDR4 ECC UDIMM modules; no extra parts or tools are needed for the SA3200D memory slots.

Should I choose this 64GB (4×16GB) kit or a different capacity for the SA3200D?

This 64GB kit fills all four slots with matched 16GB 2Rx8 modules, giving the maximum supported capacity for the SA3200D.
