Compatible Samsung DDR4 SODIMM

This 16GB DDR4 2666MHz CL19 SODIMM is built for Samsung laptops and all-in-one PCs. It uses Samsung, Micron or Hynix chips on a 260-pin unbuffered module running at 1.2V. The single stick installs in minutes to raise system memory capacity.

Who this suits and who it does not

It suits owners of compatible Samsung systems that accept 2Rx8 non-ECC DDR4 SODIMMs at 2666MHz. Buyers needing ECC registered memory, a different pin count, a higher or lower voltage, or a faster data rate should look elsewhere. Systems limited to single-rank modules will not accept this 2Rx8 design.

Deciding specification: 2Rx8 rank organisation

The module is organised as 2Rx8, meaning two ranks of x8 chips. Your Samsung service manual or motherboard documentation must confirm support for dual-rank 260-pin DDR4 SODIMMs at this density. If the platform only supports single-rank modules, this stick will not be recognised.

Questions about this item

Does this 260-pin SODIMM fit the standard DDR4 SO-DIMM slot in my Samsung laptop?

Yes, the module uses the 260-pin DDR4 SODIMM form factor that matches the standard slot used in compatible Samsung laptops and all-in-one PCs.

What is the correct way to seat the module so the 2Rx8 chips make proper contact?

Align the notch on the module with the key in the slot, insert at a slight angle, then press down firmly until the side clips click into place on both ends.

Will the Samsung chips on this 16 GB module need any firmware updates or periodic replacement?

No, the memory uses major OEM Samsung, Micron or Hynix chips that do not require firmware updates and have no scheduled replacement interval under normal use.
