LENOVO ThinkPad T15g Gen 2 (15" Intel) RAM upgrade specifications
The Lenovo ThinkPad T15g Gen 2 (15" Intel) features four SO-DIMM memory slots supporting DDR4-SDRAM at 3200 MHz. The upgrade specifications allow for a maximum RAM capacity of 128 GB. Compatible memory modules must conform to the SO-DIMM form factor standard. The laptop supports DDR4 technology across all available slots for RAM expansion and system optimization.

Additional Notes
- The Lenovo ThinkPad T15g Gen 2 supports 4 independent memory slots, permitting staged upgrades without complete replacement of existing modules. A system shipping with 8 GB can reach 128 GB through incremental SO-DIMM additions.
- DDR4-3200 MHz specification establishes a performance ceiling; modules rated above 3200 MHz will operate at reduced frequency unless BIOS settings explicitly permit XMP/DOCP overclocking, which ThinkPad firmware typically restricts to maintain enterprise stability.
- SO-DIMM form factor requires low-profile memory modules designed for mobile platforms; standard full-size UDIMM modules cannot physically install, and SO-DIMM height clearance (typically 30 mm) leaves no margin for heatspreader variations between manufacturers.
- Asymmetric capacity configurations across 4 slots (mixing 8 GB, 16 GB, and 32 GB modules) function within system limits but may reduce dual-channel bandwidth efficiency if modules occupy non-adjacent slots; firmware-level memory interleaving depends on slot population patterns.
- Upgrading beyond 64 GB transitions the system into uncommon territory for T15g Gen 2 deployments; BIOS compatibility with high-capacity 32 GB and 64 GB SO-DIMM modules released after the laptop's launch date requires verification against vendor compatibility matrices, as older firmware revisions may have unknown device support gaps.
- Factory-sealed memory modules typically carry individual warranty coverage separate from the chassis; third-party SO-DIMM upgrades generally remain covered under ThinkPad hardware warranty provided installations follow Lenovo service documentation, avoiding labor charges from non-authorized technicians.
