One lucky customer. Watching you straiten those pins genuinely had me holding my breath.
Imagine having to do it yourself.. on your own CPU! Haha Had to do that today.. Works Good Now!
I mentored a man straight into business, and he ran across one of these on his own board after a CPU drop. Must've had at LEAST 10 bent pins.
I refused to work on it, but I supervised the repair, and that was three years ago.
FUKN THING IS STILL RUNNING.
He taught me the same lesson you're trying to teach us, don't just give up because it looks impossible.
Thought it was irreparable when I saw those pins bent double, I would wager you go much further to repair than most repair shops, very well done.
Always a stomach drop moment when you've just finished cleaning your rig and it doesn't power/boot back up.
I had something similar a while back. Made my eyes go wide until I realized I hadn't plugged the power cord back into the wall-socket. 😅
It's the laptops that sometimes like to take an uncomfortable amount of time to display anything after being worked on that always get me.
Maybe leave CPU in socket xD
Flippin PC nerds. Clean their computers but probably never clean their rooms.
that's the best part, finding problems and solving them is what makes me tick.
This was a great 'edge of the seat' video. Some tense moments, but a steady hand and some skill won through.
Yay desktop repair! Good to see one of these again.
Tip for future reference: replacement LGA sockets are sold on some sites for anywhere between $5 and $25 depending on the socket. If you need to replace one, I suppose it's done by heating the board from below and when the solder melts it should all just fall into place.
That's if vital pins get broken, you can't really do a pin-by-pin correction.
What a legend. Glad to see some more desktop repairs!
Patience is a virtue! Full respect Sir. Awesome nostalgic #LFC journey!
Thanks for the ride! :)
Done watching, thank you very much for the informative repair video. I have learned significantly more troubleshooting & repair lessons in this tutorial video and to your other repair videos as well compared to my ENTIRE 4 YEARS OF COLLEGE due to the rotten & outdated standards of education here in the Philippines. I hope you will soon have a mini-series for Schematic & Boardview-free Voltage/Power Rail Tracing[12V/18-20V Main Voltage Rail, 5V, 3.3V, CPU/GPU Core Voltage Rail, DRAM Voltage Rail, IGPU Voltage Rail, System Agent/Northbridge Voltage Rail, PCH Voltage Rail, BIOS Voltage Rail, Battery Power Rail], Proper method of testing/checking of potentially faulty MOSFETs & ICs/Controller Chips, CPU/GPU/PCH Reballing and BIOS Bin File Editing.
Been there, done that. Quite a few years ago I found a Z170 motherboard in the bins at a by-the-pound thrift store. This was a super-deluxe motherboard, worth over $300, it even had a POST code display on it. And yeah, whoever bought it had removed the socket protector at any other time than when putting the CPU in. At some point I had time to work on the pins under a microscope thingy, and was able to move them back into place with only breaking a few.
Then a few months ago I found an i5 6500 chip at the bottom of another thrift store bin. This being the right CPU for that motherboard, I took a gamble and ordered a couple sticks of DDR4 RAM. And a cooler fan. And what do you know, I was able to get it to work. The only apparent problem was that two of the DRAM sockets, the same channel of both banks, did not work. But since I had gotten two 16G sticks, I didn't really mind, it was a miracle that it worked at all. I put it in an enormous Cooler Master case that was a curb find from years ago, so now it's a super junker system, with just the RAM and GPU bought new.
It's nice to know how many of the pins are ground and power. But still, DO NOT DUST YOUR CPU SOCKET FOR SPRING CLEANING, good grief, how stupid can you get.
great video Graham and i like the faxt you didnt just say yay it works, you made sure that it was stable.
Best pin repair I've ever seen. Damn good job!
Many thanks for doing this,I did a computer corse many years ago found it interesting,so I could build and maintain your computer for my Two daughters. Seeing how they have change and the equipment you have , most interesting
Kudos there Graham. Have done my share of bent pin jobs, and like you, have lost one or two, but they have been non critical also. A couple of those were properly folded though, so well done for getting them back where they belonged.
Lucky customer and great steady hands at work.
Very nice job. Merry Xmas from Australia
Makes me quite happy that I used AM4 socket and much more standard motherboards for my last upgrade cycle. Meanwhile, from Canada Merry Christmas and best wishes for a healthy and happy New Year.
Well I am open to discussion,.. whats worse, bent pin on 200USD mobo, or bent pins on 550USD CPU,...
I look at the likely results, and for me at least, the pins on a CPU are safer to work with. In 30 years I've not had one such damaged.@@marianmarkovic5881
always learning new things from you
thanks
Great video. Thank you
Superb repair!
Happy christmas graham,and to everyone,godbless to all😊
Great fix Graham 👍
Very good you have a steady hand i was holding my breath on a few of those you bent especially the curly one very good Graham
Amazing work … thanks for sharing
Aka the customer felt the force they used to replace the cpu and knew straight away. Seen this so many times. Nice to see a desktop repair.
I've had this conversation more than once with anxious customers who mangled their CPU socket/pins, luckily I've never heard anything else about it. The best customers I have are the ones I don't see until upgrade time, every coupla' years.
These videos are my favorites. Give us more :D
Some of those pins also connect to testing pads only used for testing and binning at the factory, some are there for the igpu in non-f skews, LOTS of pins not strictly needed.
bent lga pins are a nightmare to fix! respects to you sir😁
thanks adam that looked very nerve racking
Now that the DVD drives have pretty much gone the way of the dodo, that motherboard form factor (or mATX equivalent) would actually be kinda cool for DIY as well.
Great show!
Great save!
dude literally got lucky... i had this happen to me.. i was putting cpu in a brand new mobo... and the cpu slipped out between my fingers and bent pins that were actually essential.. man that was a hassle.... props man
That looked like game over. It's a miracle it works just fine.
One of the best! 👍
great work!
Great video as usual.
It is possibe to stretch that broken pin in a way that he makes contact. Even if it was a critical pin, it is possible to put another (or at least part of it) one in order to make contact.🙂🙂
I've seen people solder extensions onto broken pins... some would argue that you may as well go for a socket replacement at that point, but it depends what you have the setup for... BGA rework or microsoldering.
Are only hope will be the "micro robots" that we've been hearing about for years that are able to work in the human body and repair disease. After that accomplishment, the socket pins will be a cinch.
Surgical. Great work.
wow, i really thought this socket is toast. your customer got really lucky with that pin just being VSS. btw. you should put your licensed version of HWInfo on your Test-SSD...
Good job Adam, have you ever considered applying heat to pins annealing them to take some of the work hardening out of them.
youre back on my feed great stuff there
a tip until next time you try to bend pins right: use a heat gun to warm up the pins so they are more pliable either way, good job. (sorry my english is not that great due to its not my first language)
What temp did you use?
everything above 70+ Celsius would be fine@@LPgmxDan
Strange place for bend pins normally ppl break them around the edges lol, nice job again.
that was a good save ..... very lucky ;)
Nice job! 😊
excellent job
Your hands are steadier than mine! good job!
There are also NC pins, which are not used at all. Different CPU models also use different amount of pins (I have had damaged sockets that can run a i3 but not i5 or better). One little thing I would have done a bit less risky. One of the pins was left VERY close to the other one and that is risk of a short cut when the pins bend down when CPU is installed. I would have bent the one a bit more side ways. It can be done from the lower part of the pin so that there is no risk snapping the already bent part of the pin. Yes, I have done this kind of work quite a few times and this small damage is almost always repairable. I even do it without a microscope. I am lucky in this respect that I have superb macro vision since I am very nearsighted and need eyeglasses to see far.
you're a flipping artist!
Hi, great video. Was wondering what boom arm you are using for your Andonstar?
Got a suggestion for ya bud. Online you can buy dental picks in many sizes and they work awesome for this.... Great to have on hand....
"bent pins"?
It looks more like someone tried to make a möbius strip out of some of them.
That required some saint-level patience.
Top work, Graham. 134W seems very high for that stock CPU cooler - perhaps an upsell? One question: I noticed the GPU running off a pigtailed power cable; is that okay on a 12VO PSU?
Have a great Christmas and New Year.
Yea bigger cooling could unlock more power from this, although the board probably won't go past 130w, and it's not a K-sku chip, so 60-second PL2 window then you're down to 80w anyway...
Pigtailed GPU isn't ideal, but a 3070 is only looking for 220-250w, so not a real issue.
Nice work, strong candidate for word of the day "murderize" 🤣
And a happy new yearvto all😊
THE KING HAS DONE IT AGAIN YESSS
Well played Graham.
NICE WORK THNK YOU. BUT GUT A QUESTION WHAT HAPPENS IF THE PIN IS BROKEN FROM THE FISRT BEND OF THE PIN
WILL IT STILL WORK OR ITS A GAME OVER
Nice Job
AMD and Intel should take a page from Dell's recent CAMM specification for RAM. Both the expensive board and the expensive memory modules have simple, flat contact pads. And then sandwiched between them is a (relatively) cheap interposer module which has nothing but those delicate pins on both sides. If any critical pins break off, you can just replace the interposer.
I expected motherboard pins to be more resillient really, how exactly they could be damaged so much while others are fine within few mm. Even CPU pins back then were more resillient than these..
By the way i just loved extra Acer bracket! New GPUs are so heavy they even crack their own PCBs after several years of usage, such a bracket would protect GPUs very well. Nice to see there are still companies caring about long usage not producing e-waste designs.
That is one cramped case. Well fixed.
Wow! I wander if the customer put pressure on the CPU putting it back in and closing the ZIF rather than the lever do the work of putting the proper pressure. While I build my own PC, when cleaning it. I just dust and replace the thermal paste never taking out my CPU. Good job!!!
That GPU bracket was a good idea, would definitely keep the pcie slot from cracking while in shipment. That's a cover their asses idea I'm certain of it... Lol. Lot's of newer GPU cards been cracking at the slot lately, things are getting too heavy for the slot. Those who refuse to use GPU support brackets on these newer GPU's are just asking for issues, it's just stupid even if the computer isn't being shipped. All this started with the 3000 series cards onward.
It was very interesting! Thanks! I never thought somebody can brutalise the CPU socket so much...
It is actually not "so much" just a one wrong move
That's very mild damage. Look up what happens when someone drops a CPU directly on a socket.
Holding one's breath when you adjust those pins! 😲😱 What model of Andonstar do you have? Can the CPU be upgraded?
p03-650, same one I just got, they sold it to me as 4800MHZ ram, but it's only 4400mhz :l
Un danno simile si crea passando il pennelletto per togliere la polvere, solo una mente malata fa cose così.
Ne ho fatti almeno quattro in quedte condizioni. Lultimo mi sono rifiutato di ripararlo. Per la stupidità del proprietario.
Povera macchina.
Comunque anche tu hai una pazienza infinita. Bellissimo lavoro portato a termine da persona più che competente💪🏻💯🤟🏻💪🏻
Nice one....
I fixed a similar issue with someone elses pc after they upgraded their cpu. Found out the mobo pcie lanes and a couple other things got fried from some bent pins.
Wow!
@Adamant IT what's the best way to clean a PC, in your opinion ? Blow the dust out or vaccuum ?
What kind of a clutch are you to bent the pins in the processor socket?
wouldnt heating the pins make them more pliable and less bron to breakage and use a plastic tool to prevent doing too much damage to the copper pins.
"Murderise"🤣🤣
another win - this is your specialty - small parts/resoldering - you did sort of get lucky, rather the customer got lucky
I thought it was over when the pin broke!
is closelier a word I always thought the expression would be more closely
How about prime95? It works pretty hard on my systems to test.
mine has a sag bracket but the GPU doesn't even reach it as it's only a 4060TI lol
23:00 that’s on the board vendors and their dumb default PL and overvoltage - Intel spec is still 253W. Which before you scoff at that consider the 7950X can reach 260W while being markedly worse than a 14900K.
As others conclude. Very lucky customer. I hope you told them they should not remove their cpu to clean their pc next time.
When they look to be at breaking point, add some heat.
Whats the song called from 9:33 onwards?
nice safe
Nice Video ! What camera are you using ?👍
Facecam and benchcam are both Insta360 Link, the microscope is an Andonstar AD407 with a Paul L Daniels light ring.
If pins made of gold, it is relatively safe to bend them. But if is gold plated only.... Holy moly
Some say the memtest is still running...
also the RAM came in slot 2/4 for me
I've fixed a lot of bent CPU pins but I find once they're bent over too much, by bending back, they normally break off.
I wonder if a little bit of heat can make it less brittle? like 70-80C, not to melt anything around.. also bending it with a knife or tweezer its probably gonna stress a single part (the one that's already bent). would need a way to bend it back "gradually" in many small steps
very good ideas and also if the pin is missing, why not looking for donor board and take one of so little springies and solder it back to place, where it is missing.@@Nebbia_affaraccimiei
Has power supply with only 12v out become common when you build a computer?? or are they still an uncommon thing? what's the deal with only 12v power supply? do you need a lot of 5v for hard drives or other things then you struggle!?
AHDAMM IT
I'd have left some of those folded back the wrong way rather than risk snapping them. Good job regardless.
You said you got lucky. No, it was your skill and experience.
How on earth did the owner manage to curl those pins like that.
Great board repair nonetheless.
👏👏👏👏👏
😊 It's way too tiny, kinda like those dudes that work on watches and timepieces
