Synology SA3400 NAS memory upgrade
This 128 GB kit contains four 32 GB DDR4 2666 ECC registered DIMMs built for the Synology SA3400 NAS. It targets administrators who need to maximise the memory slots in that specific platform. The modules operate at 1.2 V with CL19 latency and use major OEM chips from Samsung, Micron or Hynix.
Registered ECC RDIMM requirement
The single specification that decides fit is the registered ECC RDIMM format; the SA3400 only accepts buffered modules with error correction. Unbuffered or non-ECC DIMMs will not function in this system. Each stick is a 288-pin DDR4 RDIMM organised as 2Rx4, matching the motherboard's electrical and mechanical requirements exactly.
128 GB capacity for virtualisation workloads
Four ranks per channel provide 128 GB total, giving comfortable headroom for multiple virtual machines, Docker containers and large file-system caches on the SA3400. The kit fills all available slots, so further expansion would require replacing modules rather than adding them. Performance scales with the platform's 2666 MT/s limit; workloads needing higher bandwidth or lower latency will hit the memory controller ceiling.

商品問答
What does the 2666 MHz speed mean for my Synology SA3400 NAS performance?
The 2666 MHz rating sets the maximum data rate the modules can sustain, so your SA3400 will run the memory at its supported DDR4 2666 speed for consistent throughput.
How does the ECC RDIMM registered design affect compatibility with the SA3400?
The registered ECC RDIMM format matches the SA3400's server memory architecture, providing error correction and signal buffering required for stable operation.
Will the 288-pin DDR4 modules fit the SA3400 memory slots without a heat spreader?
Yes, the 288-pin DDR4 RDIMM form factor fits the SA3400 DIMM slots directly; the modules have no heat spreader, so they install in the standard low-profile bays.
