About this tag
The bga rework tag on WindowsForum.com collects discussion of ball grid array rework and the practical limits of chip-level repair. A recent thread covers a Raspberry Pi Compute Module 5 memory transplant in which a 2 GB package was replaced with a 4 GB package, yet the module still reported only 2 GB, because Raspberry Pi deliberately blocks RAM-capacity upgrades to deter unofficial higher-capacity resales and the reliability problems they could bring. For repair technicians and buyers, the takeaway is that a clean soldering job alone no longer guarantees a working upgrade, making firmware and platform policy part of the bga rework conversation.

    Raspberry Pi CM5 Blocks RAM Upgrades Despite Chip Swaps

    Raspberry Pi is deliberately preventing RAM-capacity upgrades on at least some newer devices, according to reporting published on September 21, with a Compute Module 5 memory transplant showing that installing a working, higher-capacity chip does not necessarily increase the memory available to...
