Minor correction: you have the wrong community address under the third item in your “For right now” section. Should be !196@lemmy.world I think.

Wouldn’t that be 60 Hz without a rectifier, and 120 Hz with one? If the voltage crosses zero twice per cycle, but goes negative only once.

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

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.
