Single 4GB DDR3 1600 SODIMM for IdeaPad 100

This 4GB DDR3 1600 MHz module uses a 204-pin SO-DIMM form factor. It runs at CL11 timings with a 1.5V supply. The stick is unbuffered and non-ECC, built with major-brand components. It is validated for Lenovo IdeaPad 100 series models 100-14xxx and 100-15xxx.

Suits owners of listed IdeaPad 100 models needing

Not for laptops that only accept DDR3L low-voltage modules. Not for systems requiring ECC or registered memory. Not for builds needing more than one module to reach 8GB total capacity.

Deciding spec: DDR3 1600 at 1.5V on 204-pin SO-DIMM

This voltage and speed combination determines fit. If the target laptop specifies 1.35V DDR3L only, this 1.5V stick will not be compatible. Verify the service manual lists 1.5V DDR3 1600 before ordering.

Questions about this item

Should I pick the single 4 GB stick or look for a larger kit?

The module is sold as one 4 GB stick; the IdeaPad 100 series supports up to 8 GB in its single socket, so adding a second identical module would reach the maximum.

What does the 1600 MHz rating actually deliver in my IdeaPad 100?

The memory runs at DDR3 1600 with CL11 timing at 1.5 V, giving the rated PC3-12800 bandwidth when the laptop's memory controller operates at that speed.

Will the 204-pin DDR3 SO-DIMM fit and work in my IdeaPad 100 series?

Yes — the stick is a 204-pin DDR3 SO-DIMM, the exact form factor and voltage the IdeaPad 100 100-14xxx and 100-15xxx models require.
