4 GB DDR3 SO-DIMM for laptop upgrades

This 4 GB DDR3 module fits 204-pin SO-DIMM slots in notebooks that accept PC3-12800 memory. It runs at 1600 MHz with CL11 latency and 1.35 V operation. The single-rank 1Rx8 organisation suits mainstream laptop boards.

No cables or software included

The package contains only the memory stick; no installation media, adapters or manuals are supplied. Buyers must rely on the laptop’s own BIOS to recognise and configure the module automatically.

Verify slot type, voltage and maximum capacity

Confirm the notebook uses DDR3 SO-DIMM sockets and supports 1.35 V low-voltage modules. Check the manufacturer’s memory-qualified-vendor list and the maximum supported capacity per slot before ordering.

Questions about this item

Will the CL11 latency need tuning later?

CL11 is fixed by the JEDEC profile; no user adjustment is required on this DDR3 SO-DIMM.

What limits sustained throughput on this module?

The 1600 MHz clock and PC3-12800 bus set the maximum bandwidth ceiling.

How much heat does the 1.35 V module produce under load?

Low-voltage 1.35 V operation keeps thermal output modest for a 4 GB DDR3 stick.
