Memory upgrade on M3
Buying a M3 studio with 96GB of RAM, seems OK, but what if in few months I need to upgrade to 512 or 256GB. Can it be done?
And what could be the coasts?
RAM memory is built on the substrate holding the processor itself, and is NOT upgradeable. RAM has not been field-upgradeable since MacBook Pro 2012 Retina display models.
The way you upgrade if you need it later is the same way you get a bigger engine is a perfectly good Car. You convert the current working model to CASH (by selling it) and use the CASH to buy a model that better meets your needs.
OR, you buy more than you think you will need, and don't look back.
