Synology RS820+/RP+ memory upgrade

This 32GB kit contains two 16GB DDR4 ECC SODIMM modules validated for the Synology RackStation RS820+ and RS820RP+. The 260-pin unbuffered design matches the factory slots exactly, so the NAS recognises the full capacity without configuration changes. It targets administrators who need more headroom for virtual machines, containers or large file caches. Buyers whose chassis only accepts a single module cannot use this dual-stick kit.

Low-voltage ECC operation

Each module runs at 1.2V with a CL19 latency at 2666MHz, keeping power draw minimal inside the sealed rack chassis. ECC circuitry corrects single-bit errors on the fly, protecting data integrity during long uptime cycles. No heat spreader is fitted, relying on the system's directed airflow; acoustic impact is therefore unchanged from the stock configuration. Systems originally populated with 2400MHz or 2133MHz sticks will clock the new modules down automatically.

260-pin SODIMM form factor

The narrow circuit board slides into the RS820+/RP+ memory bays without tools, and the 2Rx8 organisation fills both rank channels per slot for optimal bandwidth. JEDEC and RoHS compliance means the upgrade does not void the Synology warranty. Builders who need registered DIMMs or modules with integrated heat spreaders for passive-cooled enclosures should look elsewhere, as this kit provides neither.

商品問答

How do I install the 260-pin DDR4 SODIMM modules in the RS820+ and what step is often missed?

Power off the NAS, remove the cover, insert each 16 GB module at an angle into the 260-pin slots until the clips click, then replace the cover before powering on.

What maintenance or replacement will this 32 GB ECC kit need later?

No scheduled maintenance is required; the modules are covered by a limited lifetime warranty and an advanced replacement programme if a fault ever occurs.

What limit appears first under sustained heavy workloads with these CL19 2666 MHz sticks?

The memory controller on the RS820+ caps the data rate at 2666 MHz, so bandwidth saturates before the CAS 19 latency becomes a bottleneck.
