8GB DDR4 laptop memory

This 8GB DDR4 SO-DIMM module runs at 2666MHz with CL19 latency and 1.2V operation. It uses a 260-pin layout and a single-rank 1Rx8 organisation. The non-ECC design suits mainstream notebook upgrades where ECC is not required.

Low-voltage operation

At 1.2V the module draws minimal power and generates little heat inside a compact chassis. Standard JEDEC timings mean no manual voltage or frequency tuning is needed. The stick runs silently because it has no moving parts.

Fits SO-DIMM slots

Installation requires an open 260-pin DDR4 SO-DIMM socket and a system that accepts PC4-21300 speeds. It frees the soldered memory slot for a second module when the platform supports dual-channel. Builders needing ECC or higher density must choose a different part.

Questions about this item

How do I install this 260-Pin SO-DIMM and which step is often missed?

Align the notch on the module with the slot key, press firmly until the side clips click, then verify the OS recognises the full 8GB.

What maintenance or replacement will this DDR4 module need later?

No scheduled maintenance is required; replace only if memory errors appear or a larger capacity is desired.

What limit appears first under sustained use with this CL19 1.2V kit?

The CAS latency of 19 cycles and fixed 1.2V voltage set the performance ceiling during prolonged workloads.
