Synology SA3200D memory kit

This 16 GB kit contains two 8 GB DDR4 ECC UDIMM modules built for the Synology RackStation SA3200D. It targets administrators who need error-correcting memory to protect data integrity in a NAS environment. The unbuffered design keeps latency low for typical file-serving workloads.

DDR4 2666 speed ceiling

The modules run at 2666 MHz with a CL19 timing and 1.2 V operation. JEDEC compliance guarantees they will also clock down to 2133 MHz or 2400 MHz if the system requires a lower frequency. No higher DDR4 speeds are supported by this part number.

Tool-free DIMM installation

The 288-pin UDIMM form factor drops into the SA3200D memory slots without cables or brackets. Common issues arise when mixing these sticks with non-ECC or registered memory, which the platform will reject. Always populate matching slots in pairs to maintain dual-channel operation.

Questions sur cet article

Should I pick this 16GB kit or a single 8GB module for my Synology SA3200D?

This kit provides two matched 8GB modules for dual-channel operation, giving the full 16GB capacity the SA3200D supports.

Will the CL19 timing at 2666MHz actually speed up my NAS workloads?

The CL19 latency at DDR4 2666MHz matches the SA3200D specification, so the memory runs at the platform's rated speed without downclocking.

Does the PC4-21300 rating limit what speed the modules run at in my rackstation?

The PC4-21300 rating equals DDR4 2666MHz; the SA3200D memory controller caps operation at that speed, and the modules also support 2133MHz and 2400MHz fallback.
