32GB DDR4 ECC SODIMM kit

This OWC kit provides 32 GB of DDR4 memory in a matched pair of 16 GB modules. It is built as 260-pin ECC unbuffered SODIMMs rated for 2666 MHz with CL19 latency and 1.2 V operation. The kit is validated for Synology ActiveProtect DP320 and DP340 systems.

For NAS and micro-server upgrades

Administrators expanding memory in a Synology ActiveProtect DP320 or DP340 will find this kit a direct fit. Builders who need registered DIMMs, non-ECC modules, or a different form factor such as 288-pin UDIMMs cannot use these SODIMMs.

ECC unbuffered 260-pin SODIMM

The decisive specification is the combination of ECC error correction with an unbuffered 260-pin SODIMM layout. Only systems that explicitly support unbuffered ECC SODIMMs can accept this memory.

Perguntas sobre este artigo

Will the 2Rx8 DDR4 2666 ECC SODIMM modules need replacement after a certain period?

The 32GB kit uses JEDEC-standard 1.2V DDR4 ECC chips rated for continuous server workloads; no scheduled replacement is required under normal operating conditions.

What limit appears first when the ActiveProtect DP320 or DP340 runs sustained workloads with this 2666MHz CL19 memory?

The memory controller caps throughput at PC4-21300 speeds, so bandwidth saturation occurs before thermal or voltage limits on these 1.2V unbuffered modules.

How much heat and power do the two 16GB ECC SODIMMs generate during all-day operation in a Synology NAS?

Each 260-pin module draws 1.2V without a heat spreader; typical power stays under 3W per stick, producing minimal heat in the DP320 or DP340 chassis.
