Raspberry Pi Firmware Locked RAM Upgrades
The company implemented bootloader restrictions in 2024 to block unauthorized memory capacity expansions on Pi 5 boards.

Do you trust companies that restrict your ability to repair or upgrade your own hardware?
Beginning September 25, 2024, Raspberry Pi introduced firmware updates that enforce RAM capacity checks on its Pi 5-family boards. This change effectively prevents the installation of higher-capacity RAM chips on base models, such as the 2GB version.
Why it matters
The policy was enacted to curb the resale of lower-memory boards fitted with unauthorized, larger chips and to mitigate support issues arising from erratic performance. It represents a shift in maintenance policy for a hardware platform historically defined by its repairability.
The firmware check validates the RAM capacity against the original factory specification stored on the device. Users can bypass this restriction by flashing bootloader version v2024.09.10-2712, though this action precludes the installation of any subsequent firmware updates.
The players
Raspberry Pi
A developer of single-board computers that provide a low-cost, open-hardware computing stack for education and hobbyist projects.
The details
The firmware mechanism operates by comparing the installed memory density against the size for which the board was originally manufactured. If a discrepancy is detected, the board refuses to boot or function as expected, protecting the system from stability issues caused by unofficial modifications. While engineers confirmed that even same-part repairs can sometimes be obstructed by these protections, hobbyists can circumvent the check by reverting to an older, unpatched bootloader version hosted on GitHub.
Timeline
September 2024: Firmware locks began appearing on Pi 5-family boards.
September 25, 2024: The bootloader containing the memory check was published.
June 2026: A senior principal software engineer at Raspberry Pi formally confirmed the policy.
The Tech Race
This restriction represents a significant pivot for the Raspberry Pi 5 architecture, which had previously allowed for open component modification. The move aligns the company with industry-standard anti-tamper practices intended to protect the integrity of the official product stack.
Users attempting to upgrade their 2GB Pi 5 boards with larger RAM chips will encounter boot failures unless they use the legacy, pre-September 2024 bootloader. Opting for this workaround is a permanent decision that forfeits all future security patches and feature updates provided by official firmware.
The takeaway
The move reflects a growing tension between the DIY roots of the Raspberry Pi ecosystem and the company's need to control support costs. Users should monitor future GitHub releases to see if the company introduces more aggressive, hardware-level verification protocols.
