Socket pin question

post #1 of 6
Thread Starter 
Ok, obviously the pins in the LGA 1155 CPU socket are very delicate. So how do they work, exactly? Do they crush down, or are they on springs? It seems the CPU would just crush them when it is locked down. Why not pins in the CPU to fit into holes in the CPU socket like other processors? Seems like lots of chatter on the web about bent pins. Anybody??

Good day

They bend down and you are screwed.


With older generations of chips (much older) the pins were on the CPU but were less fragile because there were less pins and bigger pins.
But now there is more pins with recent socket.
Since They contain much more pins, it was better to have them in the motherboard socket instead of the CPU because you manipulate the CPUs much more.




I bent some pins on my old Rampage III Extreme motherboatd (only two) and it was impossible to make it work again. I tried with a magnifying glass and a needle or tooth pick and it was impossible. (socket 1366)

That was the scariest part about my first build with that socket. I put the clamp down on the chip and heard a crunching noise. Thought for sure I did some damage but opened it back up and nothing was wrong. Clamped down again, heard the crunch, assembled the rest of pc and it posted first try. I guess that's just how it's supposed to be.

Yeah, I notice a lot of crunch with AsRock motherboards too. But none with Asus boards.

As long as the pins aren't broken, they can be straightened with tweezers if you're extremely careful. Something like a dental pick might work as well. Needless to say having broken or bent pins on a motherboard is nerve-wracking.
I also experienced the crunching noise with the AsRock board I used.

Thanks for the comments, everyone. Still, do the pins slide ever so slightly into the motherboard when the CPU is seated, or do they sort of fold down? I guess I still don't understand why the pins crunch at all, and why the LGA1155 thing was designed like that in the first place. I can see why it's important to have them all standing tall when the CPU is seated, but it just shouldn't be so nerve wracking, yes?
I do ponder these things when I'm waiting for Rage to download or Bioshock Infinite to load.
