ECC SODIMM kit for laptops and NAS

This 32 GB kit contains two 16 GB DDR4 modules that run at 2666 MHz with CL19 latency. The sticks are 260-pin unbuffered ECC SO-DIMMs operating at 1.2 V. They are designed as a dual-channel upgrade for compatible laptops, all-in-one PCs and network-attached storage devices.

Suits ECC-capable systems needing 32 GB

The modules work in devices that accept DDR4 ECC SO-DIMMs at 2666 MHz and can use a 2Rx8 organisation. They also run at 2400 MHz or 2133 MHz when the platform requires a lower speed. Systems that do not support ECC memory, or that need registered DIMMs, cannot use this kit. Buyers who want non-ECC memory or a different capacity should look at something else.

ECC unbuffered 260-pin DDR4 at 2666 MHz

The decisive specification is the combination of ECC error correction with an unbuffered 260-pin SO-DIMM form factor running at 2666 MHz. Verify that your motherboard or NAS explicitly lists support for unbuffered ECC SO-DIMMs before purchasing.

Questions about this item

Will the 2666MHz CL19 modules run stably with the 2400MHz DDR4 already in my NAS?

The kit is backwards compatible with 2400MHz and 2133MHz systems, so the new 2666MHz sticks will downclock to match your existing memory speed automatically.

How can I confirm the ECC function is active after installing the 2Rx8 SODIMMs?

Enter the NAS BIOS or DSM info centre and verify that the memory details show ECC enabled and the full 32GB capacity recognised at 2666MHz CL19.

Does the 2C6D42R8032P kit include a heat spreader or any tools I need to buy separately?

The modules have no heat spreader and the package contains only the two 16GB SODIMMs; no tools or extra parts are required for installation.
