I have an amd 64x2 5800, which had a bunch of bent pins and two broken ones. I assumed that it would not work, so I did not correct the pins and try. I was bored today, so I decided to fix it, and all the pins are fine now except the two that are broken. soooo will it work with the two missing pins? when i bought it it was 255. it would be great to get that back.
 
It was my first build. I didn't know how careful you had to be with them. First they were just bent cus I dropped it from like and inch, and then I didn't know to use a mechanical pencil or pen to fix it, so I ended up breaking two. I might try it, but I heard a rumor that it can fry your motherboard, so im a little nervous. Oh well, whats *another* rmad mobo.
 
If you're lucky ... with 1 bent pin there's a decent chance it was just a grounding pin and it will work ok ...

With two bent pins, you'll have to be exceedingly lucky, because both will need to be grounds if it's going to work.

If you want to know without risking your motherboard, you might be able to find a diagram somewhere on the interwebs which shows the pin assignements - then just check what your missing pins actually are.
 
There are quite a lot of pins that are only needed to adjust the voltage or for certain cpu features. You should check amds website. They should have the pin layout and the corresponding dependencies somewhere.
 
Yes, it CAN work, but is not likely to work.

I've seen some athlon k7's work with missing pins before. I would be hesitant because it could damage your mobo. But yes, it CAN work.
 
The question should have been "Will it Blend?". I guess it will but don't breathe the CPU smoke!
 
I love how ppl say it will fry this and kill that.
Look if a pin is missing then power just don't go to that part of the cpu.
The worst thing that will happen? It won't work.
The next thing? It works and crashes alot.
This continues to the point were it just works.
 
^Scratch that, I found one, but only one is ground. I have been reading around and varius sources say that you can fix it with ethernet wire. I didn't have an extra wire, so I took apart one of my cards and got some wire from there that fits in the socket. They say to fit it in so you can barely feel it with your finger, and then put the cpu in on top of it. Has anyone tested this to see if it actually works?
 
I'f you're /really/ good you could put a tiny blob of conductive epoxy on the remaing pad, and put a length of wire into it, then clip off the wire once it's set. You'd still have to be real careful though, as the epoxy may come unstuck when you put the latch on the socket down.

So long as there's enough pin length left for the socket to grip, you could reinforce the base of the pin with more epoxy though, so it's got a blob of non-conducting epoxy that holds it firm to the surrounding pins, over the top of the smaller blob connecting the pin to the pad.

Get a good magnifying glass and some nice ling pins.
 
what is the purpose of the second pin ? a lot of pin are ground and/or power. If the pin is address / data bus, or the hypertransport, forget it , you will had trouble...

by the way what's that : 64x2 5800, AMD never released 5800+, only 5600+ and 6000+...

put a picture of you CPU and the link to the pinout
 
Okay yea it was i typo its a 5600 sry about that. on my nexy post I will put a photo and a link to the pin diagram. BOTH pins seem to be importatnt though, so it's probably just junk... The only reason I am doing this is that I have a spare am2 mobo and with a cpu, mobo,case,monitor,odd,hdd, all I would need is ram and a psu (video too, but for now I would use onboard)

theres the link to the pin diagram

and theres the photo. I got a bit of thermal grease on it by accident while fixing so dont worry about that. one broken pin is near the arrow corner and the other one is on the edge in the top of the photo
 
my xeon e5440 worked normally in 775 socket,until i realised that one socket pin was laying down. then i just pulled it up and cpu worked all the same like without pin.
 


It would be pretty depressing if, *nine years later* the original poster was still waiting around for an answer.
