32GB DDR4 ECC SO-DIMM kit for laptops and NAS
This kit provides 32GB of DDR4 memory across four 8GB modules. It is built for laptops, all-in-one systems and NAS devices that require ECC protection. The unbuffered design fits standard 260-pin SO-DIMM slots.
2666MHz CL19 speed with 2400MHz and 2133MHz fallback
The modules run at 2666MHz (PC4-21300) with CAS latency 19 at 1.2V. They are backwards compatible with 2400MHz and 2133MHz systems, so the kit will operate at the highest speed the host platform supports. ECC adds data-integrity headroom for workloads that cannot tolerate silent corruption.
ECC unbuffered 260-pin DDR4 — the single
This kit only works in platforms that accept unbuffered ECC DDR4 SO-DIMMs. Systems limited to non-ECC memory or registered DIMMs will not post with these modules installed.

Questions about this item
Will the 2666MHz CL19 modules run reliably with the 2400MHz sticks I already have installed?
Yes, the kit is backwards compatible with 2400MHz and 2133MHz systems, so the new modules will downclock to match your existing memory speed.
How can I confirm the ECC function is active after installing the 4x8GB kit?
Enter the BIOS or UEFI and check the memory information screen; it should report ECC enabled and show the full 32GB capacity at 2666MHz CL19.
Does the package include only the four 8GB SO-DIMMs or are any tools or adapters supplied?
The box contains the four 260-pin DDR4 ECC SO-DIMM modules only; no screwdrivers, brackets or additional accessories are included.
