Make any mistakes here and you'll end up with a dead Mac and no avenue for getting it fixed. That becomes more of a problem when you consider that de-soldering and soldering the DRAM and NAND chips requires a good amount of skill, precision, and patience. More importantly, any modifications of this nature will instantly void your warranty. And, this all assumes that you or somebody you know has the skill to do it. You'll also need to shell out money for a soldering station. Of course, just because some engineers managed to pull it off doesn't mean you should try it at home.įor one, it's nearly impossible to purchase the DRAM and NAND chips you'd need for this procedure at the consumer level. The exact details about the upgrade are scarce, but roughly translated Chinese text in the post touts the apparent success and claims that "victory belongs to those who adapt." While the process involved de-soldering the existing chips and adding the new components, it apparently didn't require any firmware modifications. Reportedly, the engineers completed the feat using a soldering station to install DRAM memory chips and NAND flash memory chips.
