LENOVO Legion Y720 RAM upgrade specifications

The Lenovo Legion Y720 features two SO-DIMM memory slots supporting DDR4-SDRAM upgrade specifications. The gaming laptop model accommodates a maximum RAM capacity of 32 GB total memory at 2400 MHz frequency. Compatible memory upgrades utilize the SO-DIMM form factor standard for portable computing devices. Specifications indicate dual-slot architecture enabling modular memory expansion for the Legion Y series platform.

Additional Notes

• The 2 SO-DIMM slot configuration permits asymmetric memory population, meaning mismatched capacity modules function but operate at the speed of the slower module if frequencies differ.
• DDR4-2400 frequency represents an older generation standard; aftermarket modules rated at DDR4-2666 or higher will downclock to 2400 when installed, eliminating performance gains from faster memory.
• SO-DIMM form factor requires laptop-specific memory modules rather than desktop DDR4 variants, limiting sourcing options and increasing per-gigabyte cost compared to UDIMM alternatives.
• 32 GB maximum capacity ceiling constrains future expansion; applications exceeding this threshold cannot benefit from additional memory investment.
• Dual-channel architecture with 2 slots means single-module upgrades operate in single-channel mode, reducing memory bandwidth by approximately 50 percent until a second module is populated.
• Original equipment memory modules operating at 2400 MHz suggest first-generation DDR4 platform; third-party replacements should verify timing specifications (CAS latency) to ensure stability, as non-standard timings may cause boot failures despite frequency compatibility.
• Warranty policies vary by manufacturer; pre-installation verification of Lenovo's memory upgrade guidelines prevents accidental void-of-warranty scenarios through unauthorized component modification.
