Missing a corner pin on my Ryzen 7 2700x, will it still work?

As an inexperienced fellow, unfortunately I have managed to bend few pins on my processor and while I was fortunate enough to straighten them back, I have noticed one of the corner pins to be missing. I have spent some time researching of any possible consequences of it not being there but I still don't have a clear idea of how this might impact the overall performance of my PC.

I have inserted the processor into the socket and it sits nice and flat as it supposed to.

According to an AM4 pin mapping I could find, the broken pin on your CPU is assigned to MB_DATA[32], or the 33rd line of the data bus.

It looks like MB_DATA is the data bus since there appears to be 64 lines (0-63). I suspect the CPU may not work.

Ohh is the line 32 or 33 the corner? Could I have a peek at the map you're looking at? I really don't want to spend money on another processor :((
 
It's data line 33, which is named MB_DATA[32]. Remember the numbers are shifted over one place so 0 is 1, 1 is 2 .... 32 is 33, etc. because the CPU has 64 data lines, just numbered 0-63. It's a bit confusing.

This is the image I found, but I'm not 100% sure its AM4. I could be wrong about which pin it is.

The only thing to really do is try it and see what happens. If the pin was important, it either won't boot at all or act erratically.

Agreed, I just have to try and see. Thanks a lot for your help.
 
Back in the Socket 939 days I remember someone breaking a pin on one.

Someone mentioned stealing a pin from a different processor and dropping it into the hole that would be missing the pin. Allowing the pin to make contact where it was missing.

I don't know if I'd try it personally. I won't be held responsible if you or anyone else tries this and further damage is caused.

Just an idea.

Good luck.

there are not enough pins on that picture

that's probably am3 or fm1

there's only 961 possible connections included the void ones.

I had a suspicion that wasn't the right diagram, but it was the only one I could find that said it was AM4 and looked really close. I did a bit more looking and yeah AM4 has 1331 pins so obviously not correct.

That's sounds promising? So I might possibly get away with the one pin I'm missing?

Based on all the pin layout diagrams I have looked at, I have a strong suspicion that I might be missing one of the following; VSS, RSVD or just a grounding pin.

I saw that one and ruled it out because the four keys aren't present near the center of the CPU and the corners don't match up. Multiplying the two sides (41x43 pins) gives 1763 pins, and even subtracting the missing ones, it's far away from the 1331 pins of AM4.

Kinda sucks its so hard to find the pinout of the socket despite AM4 being out for several years now.

Despite of the pin not being there, is it only the matter of the processor working or not? Or can this impact other parts of my PC? For example breaking them?

Because I might attempt booting the PC but I'm worried that the missing processor pin might impact other parts in any means

It won't hurt anything else. It depends on the pin, could affect a ram channel, could affect pcie communication, could just be a ground. You won't know until you try it. If you kept the pin it'd be possible to reattach, especially where it's located. You could also, as mentioned, steal one from another cpu.
 
Worst case scenario your system doesn’t boot. Second worst case is a bunch of crashes and general instability. It won’t kill any other components but depending on what the pin actually did it could make things frustrating.
 
since it's on the outside, I wonder if you could potentially solder it back on? Use flux on the pin, make the pin really hot with a torch or iron. have a helper and touch the solder to the pin when your holding in place with a tweezers or a needle nose pliers? It'd for sure be a precision operation, but might be doable. If it was in the middle somewhere you'd be hosed on a solder attempt, but on the outside- you may have a shot.
 
or sell it on ebay for $60 as for parts or repair and let someone else struggle with it. Buy a new one for $160 and count it as a $100 mistake, and move one.

$100 mistakes are cheap mistakes in life. Unwelcome, but still cheap.
 
It shouldn't hurt anything to try it, but I wouldn't expect it to work unless it was a ground pin or something like that. If it passes data in any way, its likely a no go.
 
Should work if it's one of the many redundant power pins, as other said shouldn't hurt anything.
I'd try re -solder it but I'm half decent and reasonably experienced soldering 1mm2 or smaller contact points..
 
Hey guys,

I have assembled everything and booted it, I haven't installed the windows yet but that's what it shows me.

How do I know if my processor works?

Install Windows and all of your drivers and start running some stress tests \ benchmarks. The fact that your PC posts and gets this far is a pretty good sign.

Try installing Windows. It it succeeds, then try stress tests like Prime 95 Torture test overnight.
 
Looks like it's working to me but you won't really know until you try to install and load some programs.
 
Most likely fine, but get it all installed and running and if there are no odd stability issues, count yourself lucky as it's likely just one of a bunch of redundant power or ground pins.
 
Everything works, haven't spotted anything weird so far, softwares and games work good aswell. It was probably just a ground pin
 
hey guy bad news.

one your memory is a tad slow and two you installed windows to a mechanical drive.

glad to hear it's working though.
