Comment on Compression-mounted laptop RAM is fast, efficient, and upgradeable

  That was one of the things that excited me most from the iFixit video; the (LGA?) pins are a separate part that can be replaced as well. Simplifies the motherboard because then there are just flat pads on there, which means they don’t need to include the whole array of fancy pins for a second module if it doesn’t ship with one.

    Ooh, that may be a game changer then.

    yeah I didn’t really understand that part tbh. if they can connect the array using flat pads, why not make that the connection for the memoryb instead of the fragile pins? why the extra component?

      I mean there will still need to be spring-loaded pins somewhere in order to make good connection. And tiny pins means someone will bend them by accident at some point. And the pins are still a little involved to make, so taking them off means the RAM can be made cheaper. So this means:

      • if just replacing/upgrading RAM, then no need for extra pins to be made
      • if adding ram to a slot that didn’t have any before, then can also buy pins or they can come in some kits or whatever
      • when someone bends pins, then just the pins can be bought for a reasonable price, instead of replacing expensive RAM, or very expensive motherboard

    Makes me wonder why we couldn’t have a similar system with CPU’s. Accidentally drop the chip into the motherboard? You’d only have to replace £5 worth of parts instead of £500.
