You need a hot air rework station and steady hands — expect $150+ for tools.

Probably not worth it. But if you’re set on trying, here’s the real list.

A hot air rework station ($80–$150) is mandatory. Soldering iron alone won’t cut it — you need controlled airflow to desolder the old RAM chip and solder the new one without torching the board. Add solder paste ($10), flux ($8), tweezers ($5), and maybe a preheater ($40–$60) for multi-layer boards. If you don’t already own a microscope or good magnifying lamp, add $50–$100. You’re looking at $150–$350 total before you even buy the RAM chip.

But here’s the catch: you also need to source the exact compatible RAM module (not always easy), program the SPI flash if the board locks memory configuration, and have the skill to hand-solder BGA packages without bridging balls. One slip and the motherboard is toast.

If you’re asking, you probably shouldn’t. Pay a repair shop $100–$200 to do it, or just buy a laptop with upgradeable RAM next time.
