Raspberry Pi's RAM lock was built to stop scalpers, but it's blocking repairs too

Raspberry Pi has implemented a firmware restriction that prevents users from altering a board's factory RAM configuration. This move, intended to curb the sale of untested, modified boards in the resale market, also hinders efforts by repair and maker communities to replace failed RAM chips with equivalent parts. The restriction, which has been in place since late 2024, not only checks the capacity of the RAM but also stores other attributes linked to the original memory device.

This can prevent even a replacement chip of the same capacity from functioning correctly. For users attempting to fix a failed RAM IC, the limitation could render a board irreparable, even when a compatible replacement part is available. Raspberry Pi posits that the policy aims to prevent resellers from purchasing lower-memory products, installing larger chips of questionable origin, and selling them as higher-spec models.

The company argues that this could yield minor financial gains for resellers, who could potentially install a 2GB chip and resell it as an 8GB device. The restriction applies to all Raspberry Pi users, including those who are not attempting to create unofficial higher-spec models. This includes developers who may find their existing board no longer has enough memory for a new workload, as well as repair technicians who wish to replace a failed chip without changing the device's specifications.
