Ready for Lenovo IdeaPad 110

This 4GB DDR4 SODIMM module is built for the Lenovo IdeaPad 110-15ISK, 110-17ACL and 110-17ISK. It suits owners who need a single stick to fill one slot or to add memory to a vacant socket. The 260-pin form factor matches the factory layout exactly.

Simple 260-pin installation

The stick uses a standard 260-pin SO-DIMM edge connector and runs at 1.2V without a heat spreader. Unbuffered, non-ECC operation keeps the electrical load low for the laptop’s memory controller. CL17 timings at 2400MHz provide stable data transfer during everyday tasks.

Steps up from 2GB or 4GB configs

Replacing a 2GB module or adding to a 4GB base lifts the system toward the 20-socket platform ceiling. The jump is worthwhile when multitasking slows down or when the current stick is the only one installed. Buyers who want more storage or a second card should look elsewhere.

Questions about this item

What speed does the DDR4 2400 MHz SODIMM actually run at in a Lenovo IdeaPad 110?

The module is rated at 2400 MHz (PC4-19200). Your IdeaPad 110 memory controller will set the final speed, typically at or below that rating.

Will the 260-pin SO-DIMM fit the memory slot in my IdeaPad 110-15ISK?

Yes. The stick uses the standard 260-pin DDR4 SO-DIMM form factor used by the IdeaPad 110-15ISK, 110-17ACL and 110-17ISK.

Which way round does the key notch go when I insert the stick?

Align the off-centre notch on the module with the key in the slot, press firmly until the side clips click, then verify the capacity in BIOS.
