2700x - snapped pin, ghetto repair and a lapjob!

[lexluthermiester]

Hey folks, you're getting off-topic, let's rope it in.

Maybe putting the CPU on a card that pops into a PCIe backplane?

Ask Regen, his criteria was not stupid and not obsolete(tho slighty not stupid and slighty not obsolete is okay), being obsolete that wouldn't fly with him.

 

[Mussels]

AM4 CPU would cost me around $75 Au, cant find any at all.

This fix cost me a spare SATA cable, for a CPU that had already been replaced - so if it fails in the future, i already know why.

Fair enough. I'm a bit of a perfectionist in this area things, and a loose pin that could fail at any moment would bug the ever-living-daylights out of me...

its in my sons gaming PC, not a production machine. i wouldnt do this to my primary either (which is why i got a 3700x)

There is no reason to stick with cheap pin socket interface from 1990 that bent or break so easily. Everytime you take off AMD CPU from the socket might be the last time.

Why watch Netflix and Blu-ray on a flat screen 4K TV? Stick with VHS and CRT. Dump all modern gadgets... microwave, air-condition, smartphone.

Linus has a fun video (If you can bear him as a YouTube 'celeb') on replacing broken pins. I think it can be done with pins of a different diameter. If it's longer than the others, then it can be trimmed.

 

[Bones]

Yes, pins can be trimmed without issue as long as the trimming itself is done correctly.

For what Intel uses it's a different story.
If a pin breaks off you can't simply stuff another pin in place and have it work nor can you possibly solder a single pin in - The entire socket has to go.
That along with the simple fact the board is affected and in turn you can't use any CPUs you may have for it either rendering both useless. At least if a pin breaks on the CPU it's a matter of remove and replace the CPU only, MUCH easier and cheaper in many cases to deal with.

That's why I say pins on the CPU is better than having them down in the board's socket because it only affects the CPU and nothing else, easier to get around or fix and can be cheaper to deal with too without anything else associated with the board (Spare/other CPU's) becoming unuseable too over it.

Er only if your an clumsy twat I've built plenty of PGA systems and never bent or broken a pin I've also straightened pins on CPU's people have bought me and re-soldered ones that they've broken off it's fairly easy if you have a steady hand all you need is needle nose tweezers and a soldering iron with a medium/fine tip

I think Asus at one point showed of a prototype a couple of years ago if not more where the cpu was soldiered to the motherboard like in laptops but for the desktop.

 

[dorsetknob]

Slot A and Slot 1 from back in the day ( Oh for being old enough to remember this )

 

[Bones]

Yep - Those were basically trouble-free.

I use 0.5 tip to remove what's left of the broken pin. The only problem is you need a strong wattage iron to generate the heat required to remove it. If you use a pre-heater to heat up the CPU this improves things greatly.

Soldering back a new pin can also be challenge if the pin is nearer the centre. Most users that break pins thankfully seems to be on the outside which make the task significantly easier. Break it somewhere else will test anyone's true skill in soldering, especially on AM4 due to high density. ie it's more compacted together compared to older AMD CPU with less pins.

Fantastic job!

4k, flat panels, blu‐ray actually exist and are objectively superior that what they've replaced. Lga, is just as old as PGA which was adopted earlier. So wtf are you going on about? If there was a better why don't you patent it and sell it to AMD instead of crying about it?

 

[Mussels]

can you guys stop being silly and arguing, and just be happy that a dumb idea fixed an expensive CPU?


Also that i got a nice lapjob, havent done that since my Q6600 G0 a long time ago

They really were! It was such a great idea that needed to be taken further!

I'm... kinda surprised I don't see lapping happening more, especially with the strange boosting algorithms AMD is using, where temperature is a large factor. I think delidding happens more often than lapping...

I traditionally lap, however i tried a full motherboard monoblock this time round, it is ok ,cools well but I am now pining for a decent Cpu block ,der8aurs new mounting brackets and one hell of a lapping.

your not helping with you pron pics mussels, tut.

I was just saying that the story of bent pins should have been LONG GONE. When it comes to AMD/Intel/Nvidia on hardware forums, you say one bad thing, and people jump in to defend the firm like they're shareholders or members of the board.

It's not that difficult to break or bent a pin, usually happens when you take the processor out of the socket for cleaning. It is frustrating and annoying. Go figure where to harvest a pin from... VGA cable, IDE connector, HDD, and then pray it will work again.

It doesn't matter what the competitor have. PGA belongs in the 90s and needs to be replaced by a modern alternative.

 

[Solaris17]

Nice job! I cut a staple in the 939 days and it worked. Holes are too small now I imagine.

 

[Chrispy_]

What's the alternative? Bent pins on socket?

Exactly. LGA motherboards are far worse than pinned CPU packages. The whole premise of LGA was a terrible idea from Intel to reduce its packaging costs and keep the profits, shifting the burden onto the motherboard manufacturers.

There are no advantages to consumers for moving to LGA, and several real-world disadvantages. I have fixed bent pins on both CPUs and LGA sockets, but LGA sockets take more effort. I imagine fixing a broken pin on an LGA is damn near impossible without specialist tools, yet this thread proves that a broken CPU can be soldered or kludged just fine.

 

[Assimilator]

@Mussels well done, consider posting this to https://old.reddit.com/r/techsupportmacgyver/ !

For everyone arguing about PGA vs LGA, please note that @Regeneration wasn't arguing that one is superior to the other. They were merely opining that this pin nonsense is a royal PITA and that we honestly should have something better by now, and I think we can all agree on this.

Slot 1/Socket A were great, but they weren't intended to "fix" the pin issue - rather, they were a cost-saving measure to prevent low yields. They also had a mere 242 pins, compared to the 387 of their predecessor Socket 8. Considering the ever-higher pin counts (AM4 has 1331, Alder Lake supposedly 1700) and densities, I don't think we'll ever see a return to the slotted form factor - particularly since it complicates thermal management.

Personally, a solution to this longstanding pin issue would be far more interesting to me than the next half-decade of incremental hardware improvements.

Yes. I agree.

LGA is a step backwards from PGA, not forwards though. Waiting on science for a better answer - surely there's merit to positioning two BGA's together, maybe with a compressible perforated interposer to aid in both alignment and protection....

Come on science, you can fix this!

Quantum CPU's - there is both an installed and an uninstalled CPU in there at the same time, until someone opens the case up and then a cat dies or something
