I bent some pins on my new A64 2800+ when I tried taking off the heatsink and accidently pulled the cpu right out of the socket clip (cpu stuck to the heatsink). I tried straightening the pins last night but have some more work to do. Just wondering what your personal experience/opinion is on getting this sucker working again.

most ppl are not going to have much personal experience with fixing bent pins. its something thats not really easy to do. but my guess is that when you try and bend it back it will fall off.

good luck with it. and let me know how it goes.

Most PPL??

I know like 15 or so of my friends have had bent pends at one point or the other...just like I have had mutiple times.

I've only had one pin fall off when I tried to straighten it. I found out it was a ground, and used a conductive paint pen to trace to another.
Use a credit card to do the straightening. It's a little more gentle.

PPL = people :)

and if you have done it mutiple times you might wanna take it easy next time. the CPU justs drops in, you never need to force it in. and as fair is pulling it out. just pull that little bar up frist :)

I've had one in roughly 10 pins break. I'm not that clutsy - I've just been at it for 15 years.

I've gone over this in my head many times. The one time the pin broke it was cold in the room.

I've taken to using a hairdryer on the pins prior to bending. This goes for all pins, hd's -etc. Don't melt the things, just warm them up a bit :)


The Cedit Card is a great idea.

I been sent CPUs with bent pins on several occassiona and had Ceramique' do the adhesive effect on my A64 which resulted in those tiny delicate pins being bent upon extraction when the chip came off with the cooler. In all instances the CPUs have run perfectly, some for over 2 yrs now, even overclocked. Fixing the A64 was a PITA though since they are so damned tiny.

Exact same thing has happened to me. That damn ceramique certainly does cause an adhesive effect. I've bent the pins on 2 different P4's (one had several...like 7-10 bent pins) and used a credit card for both. They worked just fine afterward. :)

Just be careful and try and move the pins back and forth as little as possible.

I've been successful using both credit cards (for final adjustments of rows) and mechanical pencils (to get the pin close).

I have had one other case where I had a couple pins that were bent slightly outward- and all I had to do was basically line them up again and voila- no problem. This situation is a little different. In this case there is 4 pins on the very inside (the row next to the open square in the middle on an A64 - 754 chip) that have a bit of an 'S' bend to them. Imagine pushing straight down on the pin and having it buckle a little in the middle - thats what looks like happened. Anyways, I worked on it a bit last night with tweezers and a credit card but it didn't get recognized. It looks like the 4 or so pins aren't quite flush with the height of the other pins, like those 4 pins are a couple microns shorter. I also read somewhere that a mechanical pencil (without the lead in it) works well to straighten pins.

I'll work on it tonight- hopefully tomorrow I can post some good news.

FWIW: My brother tried telling me there was little to no chance of straightening the pins and having it work again- hence the reason for the OP.

You can take little individual wires from an electrical cord or something and use them to fill the gap in the holes for those pins. If ensuring contact is being made between the pins and socket doesn't work it's FUBARed most likely.

I've had a 100% success rate, except for those times I was intentionally trying to break pins off for pin-mod purposes. :)

I've had maybe two retail boxed processors show up with slightly bent pins. Hah, really funny, yesterday I opened up a new P4 3.2E retail box from Newegg. Brand new, sealed in box, etc. etc. Well, the CPU had a very obvious oily thumbprint on the heatspreader. The new packaging from Intel lets you see the CPU and the fan, and you could clearly see the thumbprint.

To avoid the heatsink pulling the CPU out (have seen that a few times) give the heatsink a tiny twist to break the seal before lifting it up. Seems to only be a problem with CPUs using heatspreaders.

Worst bent pin stories...

Once my business partner was bringing parts in and he was holding a few trays of P100 processors. Top tray slid and he caught it mid stride, but one CPU fell out and landed on his boot as his foot was going forward. The poor Pentium 100 flew about 40 feet. Worked just fine after pins straightened.

That's not the worst.

Waaayyy back in the day, shipped a desktop system with an AMD 5x86-133 (basically a 486DX4-133). It was a residential delivery and the woman wasn't home, so the UPS driver left the package in the back yard so that it wouldn't be stolen. Problem was that the gate to the back yard was locked, so he dropped the system over a 6' fence. The HSF was designed to clip onto the sides of the CPU. The CPU broke loose and bounced around inside the case with the HSF still attached. A full 100% of the pins were bent. Most were completely flattened against the CPU and some at the edges were bent over the edge. I managed to resurrect the CPU after a LONG time. That was the first CPU with bent pins that I worked on and boy was it a trial-by-fire.

My OEM 3500+ had come out of its package and was freely boucing around the shipping box when I recieved it (imagine the opening scene of Ace Ventura). Two or three of the outermost row pins were bent, with extra bent pins near the corners. There were also bent pins randomly dispersed throughout the chip.

I spent the better part of 2 hours painstakingly bending the pins back with a pair of tweezers and my thumbnail. At the end, I used a needle to straighten entire rows of pins. I gently pushed the processor into the socket, and it was no go, so instead of forcing it, i took another look and found some pins that had bent back near the corners where i was holding the proc. After a few more minutes of fussing with the needle, the chip went in, but it didn't "slide in"; it snapped in, kinda like a static-friction type thing. You know, when you're pushing a box across the floor, at first you apply strong pressure and nothing happens, but once you overcome static friction, the box begins to slide fast with less pressure applied. Maybe that was a convoluted way of stating it, but my processor was more like that when i inserted it. And to answer your question (finally) the mobo recognized the procesor fine on the first try.

If I could make any suggestion, it would be to get a magnifying glass, because I don't have any vision problems and yet my eyes had some trouble being able to focus on the pins - especially pins surrounded on all sides by other pins. Wow i just said pins a lot. pins pins pins

That is why I take a credit card with a light (white) colored face and place it next to every row of pins in both directions to verify correct alignment. Helps alot as you are now just looking at 20 or so pins at a time.

Edit: piss poor grammar

yea i when i used to be a hack with old pentium systems i constantly bent pins because the cpus weren't worth anything. i used to just use an ID or CC to fix the rows

Can't say I've ever had this problem. Nor broken cores, not borken traces in my PCB's like you morons do.:)

These are sensitive instruments people treat them as such..a simple planar 'twist' of the HS will break any TIM 'lock'...maybe I'm just careful because I spent years in labs handling dangerous chemicals... Who knows.

I've also had the cpu(P4 3.2) yanked right off while removing the hsf, but it was heavy though--the Zalman 7000A-Cu. All the pins came out straight without a slight bend. Maybe this only happens on AMDs?

There was a bent pin on the VGA cable on my old P5-100's 15" CRT, though I didn't know it for the longest time. For some reason, the monitor lost all ability to display the color red some time after I had given the rig to my parents. One day, while moving it around for them, I noticed that the monitor cable had a bent pin. Oops. Some time with a pair of needlenose pliers and a pair of stamp tongs(my dad was a stamp collector) allowed me to straighten the pin out again. The monitor displays the color red once more. Huzzah!

An old friend of mine had a 15" CRT missing a pin or two entirely, and it still worked. Strangest thing.

I have bent pins on all kinds of processors even 286 buaaahh I am old. I have found the best tool for this job is Dental tools. They have some that have dental pics that are so small you can easily use them to straighten pins even s curved ones. Warming them is a very good idea as someone else pointed out. Also, Get a magnifying light table lamp. They are cheap and will save your eyes especially with the 754 due to the pin density.

Must be the rectangular DIPP packaged 286 chips because the square ones don't have pins and drop into a socket like the LGA775 chips.

That's harsh, Zebo, harsh. :laugh:
