Lenovo LEGION Y720 CUBE compatible DDR4 upgrade

This 8 GB DDR4 module is built for the Lenovo LEGION Y720 CUBE desktop. It installs in a standard 288-pin DIMM slot and runs at 2400 MHz with CL17 timings at 1.2 V. The unbuffered, non-ECC design matches the system's original specification.

Replaces factory memory

The kit contains a single 2Rx8 stick, so it can replace an existing module or pair with an identical stick to enable dual-channel bandwidth. The platform supports a maximum of 32 GB across two sockets, making this the largest single upgrade step available.

Handles 8 GB workloads.

Eight gigabytes covers mainstream gaming, office suites and light content creation without paging. Demanding workloads such as video editing, virtualisation or large data sets will hit the 32 GB ceiling and require a different platform.

Questions about this item

Will the 288-pin DDR4 module fit the two DIMM slots in my Lenovo LEGION Y720 CUBE?

Yes, the 288-pin DDR4 DIMM matches the two slots on the Lenovo LEGION Y720 CUBE, which supports up to 32 GB total.

Do I need to change any BIOS settings when installing this 2400 MHz CL17 stick?

No BIOS change is required; the module runs at 1.2 V with JEDEC-standard 2400 MHz CL17 timings, so the system configures it automatically.

When should I consider replacing this memory module?

Replace it only if diagnostics report errors or the system becomes unstable; otherwise the limited lifetime warranty from Computer Memory Solutions covers manufacturing defects.
