4GB DDR3 1333 laptop module

This SK hynix module delivers 4GB of DDR3 memory at 1333 MT/s with a CAS latency of 9. It uses the 204-pin SO-DIMM form factor and operates at the standard 1.50V. The stick is unbuffered and non-ECC, matching the common specification for mainstream laptop upgrades.

Everyday laptop upgrade

It suits owners of compatible DDR3 laptops who need a single 4GB stick to replace a failed module or to fill an empty slot. Buyers whose systems require registered or ECC memory should look elsewhere, as this module provides neither feature.

DDR3 1333 speed and 1.50V voltage

The decisive specification is the DDR3 1333 (PC3 10600) rating combined with 1.50V operation. Only laptops that accept this exact speed and voltage will recognise and run the module correctly.
