Synology NAS DDR3 ECC kit

This 16 GB kit contains two 8 GB DDR3 1600 modules built for Synology NAS units. Each stick is an unbuffered ECC UDIMM that runs at 1.35 V. The modules use major OEM chips and are tested for stability in network-attached storage workloads.

DDR3 1600 platform ceiling

DDR3 1600 tops out at PC3-12800 bandwidth and CL11 latency on this voltage. The 240-pin UDIMM form factor fits only boards wired for DDR3 ECC unbuffered memory. Systems that require registered DIMMs or a different DDR generation cannot use these modules.

2Rx8 rank per module

Each 8 GB module is organised as 2Rx8, a density that the target NAS memory controller must support. If the system documentation calls for 1Rx8 or 4Rx8 ranks, this kit will not be recognised. Check the rank requirement before ordering.

Questions about this item

Should I choose the 2 x 8 GB kit or a single 16 GB module for my Synology NAS?

The kit provides two matched 8 GB modules for dual-channel operation, which Synology NAS units typically require for full bandwidth and ECC integrity.

What does the 1600 MHz speed mean once installed in a Synology NAS?

The modules run at DDR3 1600 (PC3-12800) with CL11 latency, delivering the rated throughput the NAS memory controller expects for ECC error correction.

Does the 240-pin DDR3 ECC UDIMM interface limit capacity or speed in practice?

The 240-pin DDR3 ECC UDIMM form factor caps each slot at 8 GB and the bus at 1600 MHz, so this 16 GB kit uses two slots at the maximum supported frequency.
