Samsung-compatible DDR4 SODIMM upgrade

This 8 GB DDR4 2666 MHz SODIMM is built for Samsung laptops and all-in-one PCs that accept 260-pin unbuffered non-ECC modules. It suits owners who need a straightforward capacity increase without changing voltage or latency settings.

Single-module 1Rx8 configuration

The stick ships alone as a 1Rx8 1.2 V unit with CL19 timing, so it plugs directly into an empty slot or replaces an existing module without requiring paired installation or BIOS tuning. No heat spreader is included, keeping the profile low for tight chassis.

CL19 latency at 2666 MHz

The CAS latency of 19 cycles at the rated 2666 MT/s speed determines how quickly the memory responds to requests; systems that require tighter timings or higher frequencies will not match this specification. Buyers who need lower latency or faster data rates should look elsewhere.

Questions about this item

Will the 1Rx8 rank configuration need any firmware updates or matching modules if I add another stick later?

The module is a single-rank 1Rx8 design, so adding a second identical stick keeps the memory controller in dual-channel mode without requiring firmware changes or matched kits.

Does the CL19 latency at 2666 MHz become a bottleneck before the 1.20 V power limit on long workloads?

At DDR4 2666 the CAS 19 timing is the first constraint you hit; the 1.20 V supply stays within spec well before latency limits sustained throughput.

How hot does the bare PCB get without a heat spreader when the laptop runs all day?

Without a spreader the chips rely on chassis airflow; at 1.20 V typical SODIMM temperatures stay under 60 °C in normal laptop ventilation.
