Legion Y520 / Y720 upgrade

This 16 GB DDR4 SODIMM is built for Lenovo Legion Y520 and Y720 laptops. It targets owners who need more capacity for multitasking, content creation or gaming on those specific models. The module fits the 260-pin SO-DIMM slots used by both series.

Single 16 GB module impact

The kit contains one 16 GB stick running at 2400 MHz with CL17 timing at 1.2 V. Adding it raises total memory toward the platform maximum of 32 GB across two sockets. The unbuffered, non-ECC design matches the laptop's memory controller without extra configuration.

Check your current layout

Verify which of the two SODIMM slots are already populated before ordering. If both slots are full, a 16 GB module cannot be added without removing existing memory. The system accepts up to 32 GB total, so plan the final configuration accordingly.

Questions about this item

Will the 1.2V DDR4 SODIMM need any replacement or maintenance after installation?

No maintenance is required for this 1.2V DDR4 module; it is a solid-state component with no moving parts and carries a limited lifetime warranty from Computer Memory Solutions.

What limit appears first when the 2400 MHz CL17 memory runs under sustained load?

The CL17 timing at 2400 MHz sets the latency floor, so sustained workloads hit the CAS latency limit before bandwidth or voltage constraints become a factor.

How much heat or noise does the unbuffered 2Rx8 stick produce during all-day operation?

The module has no heat spreader and draws only 1.2V, so it runs silently with minimal thermal output even during continuous use.
