Compatible DDR4 SO-DIMM for Lenovo IdeaPad

This 4 GB DDR4 2400 MHz module uses a 260-pin SO-DIMM form factor and runs at 1.2 V with CL17 timings. It is unbuffered, non-ECC memory built with major-brand chips and carries a limited lifetime warranty from Computer Memory Solutions. The single stick is designed for direct installation in select Lenovo IdeaPad models.

Verify your IdeaPad model and slot availability

Confirm that your laptop matches one of the listed IdeaPad 130, 310-14IKB, 330S-xxx (Intel) or 510-15ISK variants before ordering. The system supports a maximum of 12 GB across a single memory socket, so this 4 GB stick will occupy the only slot. Ensure the existing module, if any, is also DDR4 SO-DIMM to avoid mismatched generations.

Replaces or adds to factory DDR4 in supported

Use this upgrade to replace a lower-capacity DDR4 module or to populate the sole slot on models that shipped with less memory. The jump is worthwhile when the current configuration leaves the single socket empty or holds less than the 12 GB ceiling, allowing the system to reach its full supported capacity.

Questions about this item

Does the package contain only the memory module or are tools and adapters included?

The box contains one 4 GB DDR4 2400 MHz SO-DIMM stick; no tools, brackets or adapters are supplied.

Should I choose the CL17 2400 MHz stick or a faster CAS-latency version for these IdeaPad models?

The supported modules run at DDR4 2400 with CL17 timing; a lower-latency part would still operate at 2400 MHz and CL17 on this platform.

Will the rated 2400 MHz speed actually be reached once the module is installed in a Lenovo IdeaPad 330S?

The memory runs at DDR4 2400 (PC4 19200) at 1.2 V without any BIOS changes on the listed IdeaPad models.
