8GB DDR4 2666MHz SODIMM for laptop upgrade

This 8GB DDR4 module runs at 2666MHz with CL19 latency and 1.20V operation. It uses a 260-pin SO-DIMM form factor and an unbuffered, non-ECC design. The stick is built as a compatible replacement for Samsung M471A1K43BB1-CTD and related part numbers.

Single-module configuration simplifies installation

The kit contains one 8GB stick in a 1Rx8 layout, so there are no extra modules to manage or match. This lets you add capacity to a single free slot or replace an existing stick without buying a pair. Testing is performed on each unit before it ships.

DDR4 SO-DIMM limits maximum speed

The DDR4 interface caps this module at 2666MHz and 8GB per 260-pin slot. Systems that require ECC, registered memory, or voltages other than 1.20V cannot use this stick. Buyers needing higher frequencies, larger single-module capacities, or error-correcting features must choose a different memory technology.

Perguntas sobre este artigo

Will the CL19 latency require any adjustment or replacement over time?

The CL19 timing is fixed by the module's SPD and needs no maintenance or replacement during its service life.

What limit appears first when the SODIMM runs at 2666 MHz continuously?

The 1.20 V operating voltage and unbuffered design set the thermal and stability ceiling under sustained load.

How much heat or noise does the 8 GB DDR4 module produce during all-day use?

The 1.2 V DDR4 SODIMM runs silently with minimal heat; typical laptop airflow keeps it well within safe temperatures.
