LENOVO ThinkPad T495 RAM upgrade specifications
Lenovo ThinkPad T495 RAM upgrade specifications indicate a single SO-DIMM slot supporting DDR4-SDRAM memory at 2666 MHz frequency. The laptop features on-board memory combined with one upgradeable SO-DIMM slot, providing maximum RAM capacity of 32 GB. Compatible memory modules must meet DDR4 specifications and fit the SO-DIMM form factor for proper installation and system compatibility with this T-series model.

Additional Notes
- The Lenovo ThinkPad T495 contains soldered on-board memory that cannot be removed, meaning only the single SO-DIMM slot is accessible for upgrades or replacement.
- Installing a 32 GB SO-DIMM module will create an asymmetrical dual-channel configuration with mismatched capacities, which reduces memory bandwidth efficiency compared to symmetrical configurations.
- DDR4-2666 MHz memory operates at a relatively conservative frequency; newer DDR4-3200 MHz modules remain backward compatible but will downclock to 2666 MHz, eliminating any performance advantage from higher-speed modules.
- The single upgrade slot eliminates the option to add memory while preserving existing modules, requiring either replacement of compatible existing RAM or acceptance of capacity asymmetry.
- SO-DIMM modules occupy minimal physical space but have limited thermal management properties; prolonged operation at maximum capacity may generate more heat than the thermal design accounts for in this chassis class.
- Memory upgrades performed by end-users on this model typically fall outside manufacturer warranty coverage; professional service replacement preserves warranty protection.
