Samsung-compatible DDR4 SODIMM upgrade

This 32 GB DDR4 2666 CL19 module is built for Samsung laptops and all-in-one PCs that accept 260-pin SODIMMs. It delivers a straight-forward capacity increase for owners of those systems who need more memory for multitasking or heavier workloads.

Single-slot 2Rx8 layout keeps one socket free

The 2Rx8 organisation packs the full 32 GB into a single stick, leaving any second SODIMM slot open for future expansion. No heat spreader means the module fits tight chassis clearances where taller sticks would not seat correctly.

1.20 V operation limits heat and power draw

Running at the standard DDR4 voltage, the unbuffered non-ECC stick adds minimal thermal load to a compact laptop or AIO enclosure. Fan noise and battery impact stay close to stock levels during typical productivity use.

Questions about this item

Will the CL19 latency become a bottleneck during sustained workloads?

CL19 is the rated CAS latency for this DDR4 2666 module; it remains constant under load and does not increase with sustained use.

How much heat and power does a 32 GB 1.2 V SODIMM produce when running all day?

The module operates at 1.20 V with no heat spreader; DDR4 SODIMMs at this voltage typically stay cool and draw only a few watts under continuous operation.

What must my Samsung laptop already have to accept this 260-pin 2Rx8 upgrade?

Your system needs a free DDR4 SODIMM slot that supports 2666 MT/s PC4-21300 non-ECC unbuffered memory and can address a 32 GB 2Rx8 module.
