16 GB DDR4 SO-DIMM for laptop upgrades

This 260-pin module delivers 16 GB of DDR4 memory at 2400 MHz with CL17 latency. It is built for notebooks that accept PC4-19200 non-ECC SODIMMs and need a single-slot capacity increase. The dual-rank 2Rx8 organisation suits systems that support two ranks per channel.

Low-voltage operation keeps thermals modest

Running at 1.20 V, the module draws minimal power and generates little heat inside a compact chassis. Passive cooling from the laptop's existing airflow is sufficient, and there are no moving parts to add noise. The standard JEDEC voltage also avoids extra stress on the memory controller.

Fits 260-pin DDR4 slots without ECC

The SO-DIMM installs directly into any compatible 260-pin DDR4 socket, freeing the second slot for another module if the platform supports dual-channel configurations. Non-ECC operation means it works in consumer notebooks that do not support error-correcting memory. Verify the original part number before ordering.

Questions about this item

How do I install this 260-pin DDR4 SO-DIMM and what step do people often miss?

Align the notch on the module with the key in the slot, press firmly until both side clips click, then verify the system reports 16GB at 2400MHz in BIOS.

What maintenance or replacement will this 1.20V non-ECC module need later?

No scheduled maintenance is required; if errors appear, run a memory test and replace the stick if it fails.

What limit appears first during sustained use of this CL17 2Rx8 kit?

The CAS latency of CL17 and 1.2V operation set the timing and thermal envelope under continuous load.
