Capacity and fit

This 32 GB DDR4 2666 CL19 ECC SODIMM module targets Synology NAS owners and workstation users who need single-slot capacity expansion. The 260-pin form factor fits compatible laptops, all-in-one PCs and compact servers that accept unbuffered ECC memory.

Build and connectors

Samsung-sourced chips on a 2Rx8 layout run at 1.20 V without a heat spreader, keeping the profile low for tight chassis. The 260-pin edge connector slots straight into standard DDR4 SODIMM sockets; no extra cables or brackets are required.

Compatibility check

Verify that your system supports DDR4 2666 unbuffered ECC SODIMMs and can address a 32 GB single rank module. Confirm the motherboard or NAS firmware accepts 2Rx8 organisation and 1.2 V operation before ordering.

Questions about this item

What speed does the DDR4 2666 PC4-21300 interface cap at in practice?

The module runs at 2666 MT/s with a PC4-21300 bandwidth rating, delivering the standard DDR4 2666 data rate for compatible Samsung systems.

What physical slot and pin count does this 260-pin SODIMM need to fit?

It requires a standard DDR4 SODIMM slot with 260 pins; the 2Rx8 layout fits the same keying as other unbuffered DDR4 SODIMMs.

How is the ECC SODIMM installed, and which step is often missed?

Power off the device, open the memory bay, align the notch on the 260-pin edge connector, press firmly until the side clips click, then verify the new 32 GB capacity in BIOS or system info.
