Raspberry Pi locks boards to factory RAM capacities in firmware — engineer tells DIY modders 'don't waste your time' trying repairs or upgrades, company cites shady reseller scams

Raspberry Pi users are currently unable to replace or upgrade RAM chips on their single-board computers (SBCs). A Raspberry Pi engineer, PhilE, stated this on the company's forums, mentioning that devices have been locked to their original RAM sizes for some time. This decision was made to improve device reliability, according to PhilE.

However, this move appears to contradict Raspberry Pi's maker, DIY, and tinkerer-focused business model. The forum moderator explained that if labor costs are low enough, there could be a small financial gain for resellers who swap in low-quality RAM chips and sell the devices as higher-capacity units. This risks creating unreliable devices for users and creates additional support issues for Raspberry Pi.

Additionally, the Pi's firmware currently "programs in other device attributes," which means that even switching parts of the same size may not work. Despite these explanations, many users are disappointed by the RAM upgrade/repair block. Some Raspberry Pi enthusiasts have suggested implementing a "warranty bit" or a one-time firmware flag to void support for modified boards, which would have been more favorable to the community. To check your Pi's factory RAM configuration, you can refer to the provided lookup table.
