SK hynix 16GB DDR4 SO-DIMM 2666MHz

This SK hynix module provides 16GB of DDR4 laptop memory at 2666MHz with CL19 latency. It uses a 260-pin SO-DIMM form factor and runs at 1.2V. The dual-rank 2Rx8 design suits compatible notebooks needing a standard upgrade.

Who this suits and who it does not

This module fits laptops that accept DDR4 SO-DIMM memory at 2666MHz with non-ECC operation. Builders needing ECC registered memory or a different pin count should look elsewhere. Systems limited to lower speeds or single-rank only configurations may not be compatible.

Deciding specification: PC4-21300 2666MHz CL19

The bus speed PC4-21300 at 2666MHz with CL19 timing determines if this module matches your laptop requirements. Verify your system supports this exact speed and latency before purchase. The 2Rx8 dual-rank organisation is also a key compatibility factor.

Questions about this item

Should I choose the 16GB 2Rx8 DDR4 SO-DIMM or a different capacity for my laptop upgrade?

This module provides 16GB in a dual-rank 2Rx8 layout at 2666MHz CL19 1.2V. Pick it when your board supports DDR4 SO-DIMM and you need exactly 16GB; otherwise select the capacity your board and slots allow.

What does the 2666MHz PC4-21300 rating mean once the stick is installed?

The module runs at 2666MHz, delivering PC4-21300 bandwidth with CL19 latency at 1.2V. Actual throughput depends on the laptop's memory controller and whether it operates in single- or dual-channel mode.

Does the 260-pin DDR4 SO-DIMM interface limit speed or compatibility in practice?

The 260-pin SO-DIMM edge connector is the standard DDR4 laptop form factor. It carries the 2666MHz CL19 1.2V signal set, so any laptop slot wired for DDR4 SO-DIMM will accept it at the rated speed.
