Lenovo IdeaPad DDR4 upgrade

This 8 GB DDR4 SO-DIMM targets owners of the IdeaPad 320-14KBL, 320S-15AST or 320S-15ABR who need a single-slot capacity increase. The module carries the CM1024642400SO part number and is validated for those specific notebook models only.

Low-voltage unbuffered operation

Running at 1.2 V with CL17 timings, the stick draws minimal power and produces no audible noise because it has no moving parts. The unbuffered, non-ECC design keeps latency low for everyday workloads on the supported platforms.

Single-stick package

The box contains one 260-pin module and no additional brackets, cables or software utilities. Compatibility assurance comes from the manufacturer’s validation against the three listed IdeaPad models rather than from bundled configuration tools.

Questions about this item

How do I install the 260-pin DDR4 SO-DIMM into my Lenovo IdeaPad 320-14KBL, and which step do people often miss?

Power off and unplug the laptop, remove the base cover, align the notch on the module with the slot key, press firmly at both ends until the side clips click, then replace the cover before powering on.

What maintenance or replacement will the CM1024642400SO module need during its service life?

No routine maintenance is required; the module is covered by a limited lifetime warranty from Computer Memory Solutions against manufacturing defects, so replacement only occurs if a fault develops.

What limit appears first when the 8GB DDR4 2400MHz CL17 kit runs sustained workloads?

The 8GB capacity ceiling is reached before thermal or voltage limits, causing the system to swap to storage once the 8GB address space is fully allocated.
