@gloriouscow One might think "well no one would make such a mistake, duh!" but it's actually super easy to accidentally do this. I've had it happen with mere 8-bin chips even... (Ironically I'm thinking of socketed OPAMPs here as I don't have so much experience with PCs where you could actually swap chips out, but in other words it's still a thing.)
The worst thing was I had one that bent enough that when I tried to bend it back with pliers it broke off.

@gloriouscow it hurts
-
@gloriouscow ouch!
-
@gloriouscow perhaps spin it 180 degrees.

You laugh but I'm saving this to my clip art folder for when I write instructions for my soldering classes. It's a good clear drawing of everything that can go wrong.

@gloriouscow Half my console mods look like this... But it's on purpose. You gotta route some legs elsewhere on the motherboard.

@gloriouscow this image hurts, like having your own fingers bent the wrong way

What's important is it works, right?
Right?! 🥺

@futurebird@sauropods.win @gloriouscow@oldbytes.space Needs the off-by-one pin error and the magic smoke escaping to show everything.

@nazokiyoubinbou we've all done it. maybe not three simultaneously - the internally bent pin is particularly nefarious because its hard to see.

@gloriouscow you're telling me i've been doing it wrong zhis whole time??

Or have the whole thing in backwards...

@gloriouscow reminds me of piggybacking ROM/DRAM chips
(you have to have separate CAS/RAS and CS pins, most other are connected 1:1 so its often easier to just lift the few and solder the rest one on another)
@gorplop It's the lazy way to replace a bad DRAM, i've done it

@futurebird@sauropods.win @gloriouscow@oldbytes.space My usual trick is to carefully pay attention to the notch/dot to ensure that doesn't happen, oblivious to Past Me having failed to be as rigorous when installing the socket.

@gloriouscow Oof, you're not kidding. I missed it even in the illustration here clearly showing it...
-

it is a scan from a manual

@gloriouscow [chuckles]

Oh its ok, that's why there's so many pins.
