Synology DVA3219 DVA3221 memory upgrade

This 8 GB DDR4 SODIMM is built for the Synology Deep Learning NVR models DVA3219 and DVA3221. It targets administrators who need to expand the memory capacity of these specific network video recorders.

ECC unbuffered DDR4 2666 CL19 spec

The module runs at 2666 MHz PC4-21300 with CL19 latency and 1.2 V operation. It uses a 260-pin unbuffered ECC design rated 1Rx8, and is backward compatible with 2400 MHz and 2133 MHz systems.

Fits the NVR slot directly

The SODIMM installs into the existing memory slot without extra cables or brackets. ECC support helps maintain data integrity for surveillance workloads while the low-voltage DDR4 design keeps power draw minimal.

Soalan tentang produk ini

How does the 2666MHz CL19 speed translate once the module is installed in a Synology DVA3219?

The module runs at its rated 2666MHz CL19 timing when the system memory controller supports that frequency; otherwise it downclocks automatically to 2400MHz or 2133MHz while keeping ECC active.

What does the DDR4 260-pin SODIMM interface cap in practice for this upgrade?

The 260-pin DDR4 SODIMM slot limits the module to 1.2V operation and unbuffered ECC signalling, so the DIMM cannot exceed the JEDEC PC4-21300 data rate of 2666MHz.

What physical clearance does the 8GB ECC SODIMM need inside the DVA3221 chassis?

A standard 260-pin SODIMM socket with no heat-spreader clearance issue; the bare module fits the factory memory slot without extra height or cable routing.
