Additional Notes
- The Lenovo ThinkPad E15 Gen 2 (AMD) contains soldered memory on the motherboard, meaning only 1 additional SO-DIMM slot is available for expansion. Total capacity ceiling of 24 GB indicates the on-board portion occupies 8 GB or 16 GB depending on configuration.
- Upgrading to the maximum 24 GB configuration requires a DDR4-SDRAM SO-DIMM rated for 3200 MHz. Installing memory with slower ratings will operate at the lowest frequency in the system, reducing bandwidth to both the on-board and expansion modules.
- Single-slot expansion creates an asymmetrical memory layout. Dual-channel performance cannot be fully leveraged if the on-board allocation and SO-DIMM capacity are mismatched, resulting in partial single-channel operation and reduced memory throughput compared to symmetrical configurations.
- SO-DIMM modules are warranty-safe upgrades on this model. Replacement or addition of memory does not void coverage provided the installation follows Lenovo service guidelines and the module is from a certified vendor list.
- The 3200 MHz specification aligns with Ryzen mobile processor memory controllers. Compatibility with aftermarket DDR4 SO-DIMMs rated above 3200 MHz depends on BIOS support; many units enforce JEDEC standard operation at 3200 MHz regardless of module specifications.
