System-specific DDR4 SO-DIMM

This 8 GB DDR4 module is built for Lenovo IdeaPad 310 15-inch Touch, IdeaPad 320-15IKB and IdeaPad 320-17IKB notebooks. It installs as a single 260-pin stick and runs at the factory DDR4 2400 speed. Buyers whose laptops need a different pin count or voltage will not be able to use it.

Thermals noise and power

The module operates at the standard 1.2 V DDR4 voltage and carries no heat spreader. Low voltage keeps power draw modest and heat output minimal inside the tight chassis of the compatible IdeaPad models. Silent operation is inherent because there are no moving parts.

Build quality and daily use

Unbuffered, non-ECC construction with a 2Rx8 rank layout matches the original memory configuration for these laptops. The 260-pin SO-DIMM edge connector slots directly into the single upgrade socket. CL17 timing at 2400 MHz maintains the stock memory performance profile.

Questions about this item

How do I install the 260-pin DDR4 SO-DIMM into my Lenovo IdeaPad 320-15IKB, and what step is often missed?

Power off and unplug the laptop, remove the base cover, align the notch on the module with the slot key, insert at an angle then press down until the side clips click; the step often missed is pressing firmly enough to fully seat both clips.

What maintenance or replacement will this 8GB DDR4 2400 module need over time?

No routine maintenance is required; if a memory error appears later, the module is covered by a limited lifetime warranty from Computer Memory Solutions for exchange or repair against manufacturing defects.

What limit appears first when the CL17 1.2V memory runs under sustained load?

The CAS latency of 17 cycles at 2400 MHz sets the access timing ceiling; thermal throttling is unlikely because the unbuffered SO-DIMM has no heat spreader and operates at the standard 1.2 V.
