32GB DDR4 ECC kit for Synology RS2423+ and RS2423RP+

This 32GB kit contains two 16GB DDR4 2666MHz ECC UDIMM modules built for Synology RackStation RS2423+ and RS2423RP+ systems. It targets administrators who need to expand memory capacity on these specific NAS platforms. The unbuffered design matches the motherboard slots directly. Buyers whose systems require registered DIMMs or non-ECC memory cannot use this kit.

ECC unbuffered DDR4 2666MHz CL19 at 1.2V

The decisive specification is the ECC unbuffered UDIMM format running at DDR4 2666MHz with CL19 latency and 1.2V operation. This exact combination matches the memory controller requirements of the supported RackStation models. Modules with different ECC status, buffering, voltage or pin count will not function in these systems.

Dual-module kit enables dual-channel operation

The package includes two matched 16GB modules so the NAS can run in dual-channel mode, doubling memory bandwidth compared with a single DIMM. No heat spreaders are fitted, keeping module height low for dense rack chassis. No software or cables are bundled; the upgrade is purely the memory modules themselves.

Questions about this item

What does the 2666 MHz speed rating mean once these modules are installed in a Synology RS2423+?

The modules will run at 2666 MHz CL19 if the system supports that speed; otherwise they automatically drop to 2400 MHz or 2133 MHz thanks to backward compatibility.

How does the DDR4 288-pin ECC UDIMM interface limit what the kit can deliver in a RackStation?

The 288-pin unbuffered ECC form factor fits the RS2423+ and RS2423RP+ memory slots and provides error correction, but total capacity is still capped by the NAS motherboard's maximum supported memory.

What physical clearance do the 16 GB sticks need inside the Synology chassis?

Each 288-pin UDIMM is a standard-height module without a heat spreader, so it fits the RS2423+ and RS2423RP+ DIMM slots without requiring extra vertical space.
