    First rule in computer building is to always buy twice as much RAM as you actually need so you can just remove the bad stick when this happens

      Second rule of computer building is just keep the receipt until after it passes 40 minutes of memtest. Third rule is to ignore rule one, nobody does that.

      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, each 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.
