Bent/Missing pins

[WolfDeville]

I bought a used $20 1155 board that had bent pins, all but 2 were extremely easy to fix. The last 2 were sorta stuck together, (no fuggin clue how that happens) I tried separating them for a while and eventually got pissed off and got aggressive with it, one of the pins popped out and the other is back in place with a little piece of the other one stuck to it... I don't know the importance of these 2 pins, but I do know that you can get away with some missing pins depending on what they are. Here is some images of the socket if anyone could help me out. Sorry for the poor quality: https://imgur.com/a/pkTBBFV

 

Thanks!

Not the help you likely need but maybe a little.

 

lga1155 means there are 1155 pins. I suspect someone knowing off the top of their head which pins do what to be highly unlikely. 
 

Intel has a bunch of data sheets.  Some are available from the reference section of the Wikipedia on the socket. Might be able to find more interesting stuff.  A motherboard manufacturer would need to know what they all did. There are 1155 motherboards currently being produced in China so I suspect it has to be recorded somewhere.  The various data sheets Would probably make for a lot of reading and might not even be there.

 

judging from how close they are together though the concept that all of them are grounds or extraneous in some way strikes me as unlikely.  One could always just pop a processor in and see if it boots of course.

Linus might be able to tell him with his experience with dropping things on sockets.

 

But yeah, I too would pop a CPU in and see if it boots ok.

I'm a little hesitant to try booting it up incase I damage the CPU. Is there any risk of that happening? I found one data sheet but wasn't entirely sure which side is which so I figured my safest bet was coming here and hoping to get the attention of someone that knows more about this than I do. I'll keep looking for a sheet. Cheers!

There might be, yes. No way to tell really, it isn't an exact science not knowing what the pins do. They may do nothing at all or they may be super important.

im wondering if it might be faster to run a magnet over your floor to try to find the pins so you can put them back on.  Or even desoldering the whole socket and putting on a new one if you’ve got BGA reballing equipment.  This is starting to sound like a possible sunken cost fallacy.

Oh I had the pin sitting on my desk, I didn't lose it. It was just so mangled up it would be pointless trying to get it back in. I really don't know how the previous owner screwed the pins up this bad.

Off hand, my guesses from the description would be shipping without a cover or dropping something on the mobo.  If theyre that mangled little can likely be done with them.
