Dell Inspiron 11Z (1121) memory kit

This 8GB kit contains two 4GB DDR3 SO-DIMM modules built for the Dell Inspiron 11Z (1121). Each stick uses a 204-pin layout and runs at 1600 MHz with CL11 timing at 1.5V. The unbuffered, non-ECC design matches the factory specification for this notebook.

Suited for owners of this specific Dell model

Buyers restoring or upgrading a Dell Inspiron 11Z (1121) can install both modules for the full 8GB capacity. The kit will not help owners of other Dell lines or later laptops requiring a different memory generation or form factor. Systems limited to a single memory slot also cannot use both sticks.

204-pin DDR3 SO-DIMM form factor

The 204-pin SO-DIMM interface is the single specification that decides fitment. Only notebooks wired for DDR3 SO-DIMM at this pin count can accept these modules. Buyers must verify their system uses this exact slot type before purchasing.
