Synology ActiveProtect DP320 DP340 Memory Upgrade

This 8GB DDR4 ECC SODIMM is built for the Synology ActiveProtect DP320 and DP340 appliances. It adds error-correcting memory to micro servers, NAS systems or POS terminals that require 260-pin unbuffered modules. The single 1Rx8 rank installs in one slot without extra configuration.

JEDEC ROHS Compliant Warranty Safe Upgrade

The module meets JEDEC standard PC4-21300 timing at CL19 and 1.2V operation. ROHS compliance and OWC validation mean the upgrade keeps the original system warranty intact. No additional software or firmware steps are required beyond the normal BIOS memory detection.

DDR4 2666 Backward Compatibility Limits

Rated at 2666MHz PC4-21300, the stick will down-clock to 2400MHz or 2133MHz when the platform demands it. Systems that only support lower DDR4 speeds or that require registered DIMMs cannot use this module. Buyers needing higher capacity per slot or registered ECC must choose a different part.

Questions about this item

Will the ECC function on this DDR4 SODIMM need any firmware updates on a Synology DP320 or DP340?

No firmware updates are required; the module follows JEDEC DDR4 2666 CL19 1.2V specs and is validated for those models.

What speed ceiling appears first when the DP340 runs this memory continuously at full load?

The DDR4 2666 CL19 rating is the limiting factor; the module will not exceed PC4-21300 bandwidth under sustained use.

How much heat and power does the 8 GB stick draw during all-day operation in a DP320?

It runs at 1.2 V without a heat spreader, so thermal output and power draw stay low in the NAS chassis.
