ECC SO-DIMM kit for laptops and NAS

This dual-channel kit delivers 16 GB of DDR4 2933 MHz memory with error-correcting code support. It targets owners of compatible laptops, all-in-one PCs and NAS appliances who need data integrity alongside a straightforward capacity increase.

Unbuffered 260-pin modules without heat spreaders

Each 8 GB stick runs at the standard 1.2 V and meets JEDEC PC4-23400 CL21 timings. The low-profile SO-DIMM form factor fits tight SODIMM slots in thin-and-light notebooks and compact NAS units where taller modules would not seat.

Replaces slower or non-ECC DDR4 SO-DIMMs

The kit is backward compatible with 2666 MHz, 2400 MHz and 2133 MHz systems, so it works in older DDR4 platforms without configuration changes. Buyers who need registered DIMMs, higher frequencies than 2933 MHz or capacities beyond 16 GB should look elsewhere.

Questions about this item

What speed does the DDR4 2933MHz ECC SO-DIMM run at if my system only supports 2666MHz?

The kit is backwards compatible and will run at 2666MHz, 2400MHz or 2133MHz depending on the system's maximum supported speed.

Does this 260-pin SO-DIMM kit need a heat spreader to fit in a thin laptop?

No heat spreader is included, so the low-profile modules fit tight spaces in laptops, all-in-ones and NAS units.

Do I need to enable anything in BIOS for the ECC feature to work after installing both 8GB modules?

ECC operation requires a platform that supports ECC; if the hardware supports it, the feature is automatic with no extra BIOS step needed.
