Some ThinkPads are known to support more memory than their specs say. This page gathers information about those models, how much memory they can take and what special requirements that memory must fulfill.
Have a look at the Memory page for the official memory configs and partnumbers
Working memory configurations
The following table gives an overview of tested memory configurations that exceed the specified limits for that ThinkPad type.
ThinkPad | max. Specs | BIOS | Embedded Controller | Memory configuration successfully tested |
