What this module is

This is an 8 GB DDR4 2666 MHz ECC SODIMM built to the 260-pin standard and rated at CL19 with a 1.20 V operating voltage. It arrives new and is validated as a direct replacement for the Samsung M474A1K43BB1-CTD and M474A1K43DB1-CTD part numbers.

Who should use it and who should not

It suits servers and workstations that require unbuffered ECC memory in the SODIMM form factor for data-integrity workloads. Systems that need registered DIMMs, non-ECC modules, a different pin count, or capacities beyond 8 GB will not be compatible with this part.

How it fits into a build

The stick plugs into any 260-pin DDR4 SODIMM slot wired for unbuffered ECC operation and runs at the standard 1.2 V without extra cooling. Adding it frees the memory controller from single-channel limits and lets the platform handle larger datasets with error correction active.

商品問答

Does my laptop need a 260-pin DDR4 SO-DIMM slot to accept this module?

Yes, the module is a 260-pin DDR4 SO-DIMM and requires a matching slot.

Will this ECC unbuffered SODIMM work if I keep non-ECC memory in the other slot?

Mixing ECC and non-ECC modules usually disables ECC or prevents boot; use identical modules for stability.

How can I confirm the stick is running at DDR4 2666 with CL19 after installation?

Check the memory speed and latency in BIOS or a tool such as CPU-Z; they should show 2666 MHz and CL19.
