Lenovo IdeaPad 320 DDR4 upgrade

This 8 GB SODIMM is built for the Lenovo IdeaPad 320-15AST, 320-14ISK and 320-14IKB. It adds a single 260-pin DDR4 module to the laptop’s sole memory slot. The kit suits owners who need more capacity for multitasking or heavier browser workloads. It is not for systems that require ECC or registered memory.

Low-voltage DDR4 at 1.2 V

The module runs at 2400 MHz with CL17 timings and a 1.2 V supply. Unbuffered, non-ECC chips keep power draw modest and heat output low in the tight IdeaPad chassis. No heat spreader is fitted, so the stick relies on the laptop’s existing airflow. Noise and thermals stay unchanged from the factory configuration.

Single stick with lifetime exchange

The package contains one 8 GB memory stick and no additional cables, tools or software. Computer Memory Solutions provides a limited lifetime exchange against manufacturing defects when purchased directly. Buyers who need dual-channel bandwidth or more than 8 GB total must look elsewhere. The product appearance may differ from the reference image.

Questions about this item

How do I install the 260-pin DDR4 SODIMM into my Lenovo IdeaPad 320 and what step is often missed?

Power off the laptop, remove the bottom cover, align the notch on the module with the slot key, press firmly until the side clips click, then replace the cover before booting.

What maintenance or replacement will the 8GB DDR4 2400MHz module need over its service life?

No routine maintenance is required; the module has no heat spreader and no moving parts, so replacement is only needed if a fault develops or total system memory must exceed 16GB.

What limit appears first when the CL17 1.2V SODIMM runs under sustained heavy workloads?

The 2400MHz speed and CL17 latency set the throughput ceiling; the memory controller will not exceed this frequency regardless of workload duration.
