LENOVO ThinkPad T460s RAM upgrade specifications
The Lenovo ThinkPad T460s laptop features DDR4-SDRAM memory specifications with one SO-DIMM slot available for RAM upgrade. The device includes on-board memory combined with one expandable slot, supporting a maximum memory capacity of 24 GB. Memory modules operate at 2133 MHz frequency. Compatible upgrade modules must meet DDR4-SDRAM specifications and SO-DIMM form factor requirements for proper installation and functionality in the T460s model.

Additional Notes
- The Lenovo ThinkPad T460s contains soldered memory on the motherboard, meaning only 1 upgradeable slot exists for user-accessible expansion despite the 24 GB maximum capacity specification.
- DDR4-2133 MHz represents a lower speed tier within DDR4 standards, which constrains theoretical bandwidth to approximately 17 GB/s per memory channel and may create latency disadvantages when paired with newer processors expecting faster memory support.
- SO-DIMM form factor requires low-profile memory modules, restricting compatible aftermarket options to laptop-grade components and eliminating standard desktop DDR4 modules as viable replacements.
- The single upgradeable slot design means maximum practical RAM reaches 24 GB only if soldered memory allocation is 8 GB or higher; if on-board memory is 8 GB, the SO-DIMM slot accepts only 16 GB modules, capping total capacity at 24 GB.
- DDR4-2133 compatibility limits the feasible upgrade window, as consumer DDR4 production shifted toward 2400 MHz and faster variants after 2016, potentially reducing availability of new-old-stock compatible modules in current markets.
- Warranty coverage typically permits SO-DIMM upgrades as end-user serviceable components, making RAM expansion a non-invasive modification that does not trigger manufacturer service limitations.
