No solder required.
r/techsupportgore will be full of people dropping their ram on those pins and damaging them. Still cool though.
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?

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.

I’ve never had to solder laptop ram. I always buy ones that let me get in there without a complete disassembly.

I’ll buy it when its in a laptop with coreboot, which is probably never.

Their reason for soldering ram is not usually about space.
BrikoX@lemmy.zip 6 months ago
As far as I know, it’s about access times between the RAM and CPU. It’s the same reason SoCs are having RAM integrated.
ArbiterXero@lemmy.world 6 months ago
It’s about cost, space, heat and most of all “MONEY”
If I force you to buy the extra ram upfront because you can’t upgrade it, I can charge a premium for it.
