    I always heard the first rule as “stay grounded”. Having 1TB of RAM on stock just in case sounds not grounded.

    A spare kit or two should be enough for most folks. With one or two spares of everything else so you can test suspicious parts separate from prod.

    A bit of redundancy and foresight is good but no need to be excessive about it.

        OK, so let’s cut it down and say we have 4 PCs for someone with a family and home server, with 4 DIMMs each.

        You are saying the first rule of PC building says that this house should have at least 16 unused DIMMs on the shelf. I’d say 2-4 is reasonable if they are all compatible.

        “Buy two extra of everything” is a good rule and scales for the individual. “Buy double of everything” is not.
