Raspberry Pi Foundation has confirmed that recent firmware updates lock the memory capacity of its devices to the original factory configuration. This measure prevents users from manually upgrading RAM by soldering new chips onto the board, a practice previously popular among hardware enthusiasts.
The restriction was implemented starting in late 2024. According to the company, the decision aims to curb unauthorized commercial modifications. Some distributors were purchasing lower-spec models, installing higher-capacity memory chips of unknown origin, and reselling them as official high-end units, which led to stability issues and support burdens.
The firmware now records not only the memory capacity but also other hardware attributes. Consequently, even replacing a damaged memory chip with an identical one may result in the device failing to function correctly. This has sparked significant criticism from the repair community, as it effectively restricts legitimate hardware maintenance.
Critics argue that the move contradicts the company's long-standing commitment to open hardware and DIY culture. Developers suggest that alternative methods, such as warranty flags or status markers, could have addressed the issue of unauthorized reselling without completely disabling the ability to repair or upgrade devices.
The Raspberry Pi Foundation maintains that these controls are necessary as its products increasingly enter industrial and commercial markets where reliability is critical. While some older firmware versions may not yet enforce these limits, the company's shift toward stricter hardware control appears to be a permanent policy change.
