Where can I find the AM4 socket pinout

[HUSKIE]

As above. I've got this Cpu from a friend Ryzen 7 1800x, he accidentally snapped the outer pin on the Cpu. Cpu working fine before the pin knackered. Don't have Motherboard yet.

Here is the photo

I googled it but came up empty. it seems someone else had a similar issue and didn't find a pinout. Only AMD themselves know. As for that, hmm. Is likely going to be extremely difficult to repair it. IDK what to suggest . You might try it in the motherboard and see if it works , i don't think it will damage the board but not 100% sure. In that thread the OP reported some issues with audio (For some reason). YMMV

Edit: BTW this is not the AM4 socket.

Edit2: Lol it's socket 1150. dunno what they thought in that AM4 pin thread.

Don't call the morgue yet.

First, try it and see if it works. Chances are fairly good it was just a ground pin or something. If it doesn't work, you can try sticking a piece of a paper clip in the socket matching where the missing pin is. I believe @cdawall has done something similar before?

You probably won't find a paper clip small enough for that. I just use pins broken off of another crappy processor I don't care about.

Also, I've hear jewelers can often solder a new pin on.

I've done the same for a Pentium 4 with a pin from a header off a dead mobo.

I had this issue year ago....

Jeweler near me said he would have to apply too much heat to make it work. Maybe things have changed for them since 939 days, might be worth a look.

What I did to fix mine was grab some gold wire for crafting. It did take a couple of tries to cut it to the proper length to make contact yet not be too tall (when the socket is locked), but I revived a chip doing it.

Hopefully, you can just plug it into a socket and it works, but as other have mentioned, there are ways to get it back in action.

Nice alternative. Perhaps copper wire would work as well, if you found the appropriate gauge?

This is why you don't close threads that points how to repair CPU pins, no matter how old the thread.

Find yourself an none working CPU with the same pin size. Get a soldering iron with a tiny tip, (mine is 0.2) & turn temperature to very high, mine is set-to 480c. Put the tip of soldering iron at the base of the broken pin (touching the solder pad & broken pin base at the same time).

The broken pin base should de-solder & in view you should see the full solder pad. Note that before de-soldering the PCB solder pad is mostly hidden & only a tiny part is visible as it mostly covered by the base of copper pin. If you can't see the mostly cover soldered pad, just put the soldering iron full contact on the broken pin with a bit of solder & try & slide off the base of the pin when hot enough, DO NOT FORCE IT. After you have de-soldered the broken pin, there is two method how two solder in the new pin.

If you look carefully at the OP screenshot, you can just about see the solder pad at each pin.

As for AM4 pinout, manufacture's of motherboards will have this information also.

Off the top of my head it was 18 or 22 gauge. Absolutely solid copper wire would work. Pretty sure my "gold" wire has a copper center under the plating.

Not confirm, but this maybe AM4 pinout. Use a metre to see if it tally-up. EDIT UPDATE: False information not AM4

 

[Sybaris_Caesar]

Can't you just sit the pin on the socket (assuming you still have it) and put the cpu on top of it?

Nah, the lack of B2 and H3 tells me that it's AM3. Besides, AM4 has no pins in the center.

User(s) claim this works, but I don't see how it can work. You have to see how the socket works, so I suggest User(s) to find any dead motherboard & remove the top part of the CPU socket, It will surprised you. What I fear is, if the pin is just place in the socket, there is a risk it could be pull under the socket.
The pin can cause short circuit if it gets trap beneath the socket, & if it does get trap, there is no way to get it out, other than do a full de-solder of the CPU socket.

Got that from a Reddit Thread, so it's false information.

I was gonna say...I've actually soldered tinier shit with success(with a big ass chisel tip no less). So that's what I'd do. Nothing like a job done right!

For a professional finish, I used a full infrared workstation. There is no sign that the CPU pin has been replaced with the naked eye, it looks normal. You can used a soldering iron to solder in the new pin, but there will be visible signs it has been repaired.

For me with the Pentium 4 all it did was fall down into the socket. No contact was made.

A small strand of solid copper wire such as found for the wiring of a lighting ballast is the right size.
It has to be the solid (Non stranded) type wire. You can measure out how long it needs to be, cut it and then place it into the hole where the broken off pin would have gone and it should work. I've seen it done before but do be aware it's only suggested for chips ran at stock clocks and voltage due to the nature of the fix.

It is possible to resolder the pin but if your soldering skills aren't up to task it's best to let someone else do that.

This is the correct result I expect to see, open circuit. Besides it not a proper contact even if one was made using this method. ie possible intermittent HR/open circuit.

Will be updated this topic once the motherboard will be arriving tomorrow.

The only way it worked was to cut a slightly longer pin so it touched the PCB in the pin hole, and be in contact with the pad above. Not sure how that would work with the newer sockets.

Yes that can work, but your still at the risk of intermittent contact. I know what you are saying, cut a pin a bit longer & force a good contact by the CPU pressing down on the pin. How reliable do you think this is. I would not trust it, you better off soldering a pin back on the base of the broken pin.

I've found this blurred picture off hard forum,

 

[juiseman]

I would just try it; if you try to fix it, you may break it.

If it passes post, its probably fine. it won't power on self test if something is wrong...
there is a lot of ground or NC's on that pic assuming its an AM4 Pin out . good chance the broken pin is 1 of those.
I don't see this causing damage to the board or chip with a missing pin...

here is what i would do.

1. buy a cheap AM4 board
2. if it works keep it; if not return it.

 

[Vya Domus]

There is a big problem with this, if the surface area in contact is really small and this happened to be a pin that carries power it may very well burn up killing the CPU for good.
