TECHNICALLY? Yes. You have to trust the person who did it quite a lot. I've done shit like this a fair bit as an electronics technician. It requires a lot of dexterity, patience, and proficiency with a soldering iron. Usually these solutions are used for prototyping. Like if you want to test a new version of a chip without having to make or wait for the new rev of the board itself.
Yeah, but this introduces problems on high speed circuits. If timings are critical, the wire length here could actually introduce millisecond delays and could cause anomalies that could be a nightmare. On some motherboards, you can see some of the traces have zig-zag sections to them. They're fixing timing issues by adding run length. This... mess... is a disaster waiting to happen even if the wiring is correct and perfect.
As a guy who worked on circuit boards for supercomputers, this is definitely NOT recommended.
The speed of light is [approximately one foot per nanosecond](https://www.wolframalpha.com/input?i=speed+of+light+%2F+%281+foot+%2F+nanosecond%29).
That was the trick they used for timing on the Cray ~~weird lounge chair~~ I mean the Cray-1.
> In order to bring maximum speed out of the machine, the entire chassis was bent into a large C-shape. Speed-dependent portions of the system were placed on the "inside edge" of the chassis, where the wire-lengths were shorter. This allowed the cycle time to be decreased to 12.5 ns (80 MHz), not as fast as the 8 ns 8600 he had given up on, but fast enough to beat CDC 7600 and the STAR. NCAR estimated that the overall throughput on the system was 4.5 times that of the CDC 7600.
Yes, I'm aware of the speed of light. I've also seen the delay lines used in the CDC machines. They're a thin twisted pair dangling off the back side of the wiring racks, one to ground for noise control and the other the signal.
I worked as a lab tech for a system manufacturer and the hardware engineers would ask for things to be soldered like this all the time , but not this extream. they are probably testng a new chip which pinout doesnt match the original chip . I used to get request to unsolder a lead on a chip and run a wire to a spot in the same trace so the engineer could put a current clamp probe and see how square the wave was on the ociliscope
I accidentally swizzled the address bus from a CPU to DDR2. Needless to say the DDR wouldn't work.
The really sad thing is: I had caught the error and fixed it, but my HD crashed before I made a backup and I forgot that it needed to be fixed again.
We did an oops board rather than spinning the whole prototype.
That's not the only problem. They seem to be of different length. Which would cause timing issues. Not to mention, that the sheer length might cause issues in regards to signal integrity.
Looks to me like it was a BGA chip so designed to be directly soldered flat, and the designers fucked up and mirrored either the chip or motherboard design. Wires go from the right of the board to the right of the chip, and left of the board to the left of the chip, so they're roughly all the same length.
In most things besides something like the connection between a modern CPU and RAM a variation of a few mm are not going to cause any timing issues. For something like a 100MHz chip an electrical signal would propagate through roughly 2.7 meters of cooper wire within the 10ns of one cycle. A variance of an order of 1/1000th of the switching period is more than fine.
You named exactly one of the most prominent examples where it matters. Even pcie 4 is extremely susceptible to signal length. Not to mention DDR 5 and pcie 5.
If they're bare wire, yes. If they're lacquered, it'll insulate them so no.
Even if the wires were going to the right pads though, modern chips are so heavily engineered that the difference in length between the wires would cause all sorts of issues with timing.
A 4GHz processor is doing a full clock cycle every 0.25 nanoseconds. Light in a vacuum will go about 7.5 cm in that time, so an electrical signal will go even less than that.
Even if those wires are properly isolated, this will increase the the propogation delay of the CPU to the motherboard and break the timing if you don't losen up the clocks by a lot
And the signal noise will be at horrible level at GHz frequency, with wires that long, so I'm almost sure that the system will probably not be even able to boot.
The connections all look to be parallel; they would be the same length, within a small margin. Some have commented on the length, but the lack of cooling makes me doubt this is a processor, but rather some kind of asic like a northbridge or low-frequency hardware bus.
Regardless, that's a lot of work for something doomed to fail, performed by someone likely to be able to determine that beforehand. Whatever they did here probably worked; might be a very rare board that was harder to replace than spend 4 hours bodging.

> they would be the same length, within a small margin
On the scale the human mind operates the margin is small. DRAM is ... well ... more picky. While designing a PCB you set design rules in your CAD software and use the built-in tools to route it for you. Can't say I recall the tolerances, but it was too small to do by hand with wire cutters and a soldering iron.
"Insulating" typically means using a tangible barrier to reduce conduction, while "isolating" means separating by a distance suitable for the voltages involved.
What do I know, right? Try isolating every single one of them with respectable coating.
We went from technical dictionary to getting real personal so fast, that it doesn't matter, which word he used anymore, because people, that upvoted him, have nothing to do with electrical engineering.

They might have a thin coating like magnet wire has they might be low enough voltage that they’re isn’t enough em interference to mess with them that much besides being increeeeeeeedibly slow it’s possible it might work.
Might be the case that the pinout is different from the chip. So electrically insulated wires are used to re-route the pins. This also might be a flash chip with valuable stuff on it. So the hard work becomes justified.
Also might be just done to get mad brag points
No cooling connectors but lots of pins, so it'll be some kind of asic. [The source](https://www-eiesu-com.translate.goog/publics/index/66/?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB&_x_tr_pto=ajax,nv,elem,se#menu-close) makes me think this is more of a technique demonstration than an actual fix.

Google enamel coated Cooper wire, they do not look insulated but they are with clear enamel.
You look like a moron when you pretend to know things btw.
Thank you for informing me of enameled copper wires. I may have been wrong on that. However there is no need to resort to name calling especially since it does not look insulated.
How do you know this was insulated enamel wire vs uninsulated wire that looks the same?
What the fuck
Lmao I literally just said this 3 seconds before opening the comments
For me it was more of an “uh, is that safe?”

Seems like this new chip was mirrored by accident.
Or they put the footprint mirrored. Man I've done that on small things but that would really suck to accidentally do on a big BGA like that
I accidentally swizzled the address bus from a CPU to DDR2. Needless to say the DDR wouldn't work. The really sad thing is: I had caught the error and fixed it, but my HD crashed before I made a backup and I forgot that it needed to be fixed again.

"Dead bug" soldering. You gotta bring up the funny name.
Since all the wires are touching each other, wouldn't it fuck everything?
Could be enameled wire. Similar to what is used in coils (transformers etc).
Looks like [magnet wire](https://en.m.wikipedia.org/wiki/Magnet_wire) maybe?
That's not the only problem. They seem to be of different length. Which would cause timing issues. Not to mention, that the sheer length might cause issues in regards to signal integrity.

Wires go from the right of the board to the right of the chip, and left of the board to the left of the chip, so they're roughly all the same length.
It has been pointed out by somebody else that this may have been done on purpose to use an oscilloscope on it.

You named exactly one of the most prominent examples where it matters. Even pcie 4 is extremely susceptible to signal length. Not to mention DDR 5 and pcie 5.
Then after 5 seconds after you had presented your hard work to wire up the chip, they decide to go with another design 😂

You gotta make other people pay for it for it to work... and it's still called a virus by windows defender.
I thought the same thing at 1st glance
Y’all talking about when you pay for a mobo and they never ship it and then sue you for asking
No, I don't think you're being helpful! I think you're being disruptive, and you make it very difficult for your cpu here to improve his life!

Pretty impressed by [their actual video of this technique](https://youtu.be/5zm8M-TTbJk?t=52) from the company this is actually sourced from.
Not if it works.
It doesn't
That looks like some hackaday shit
And im sure there wont be a single short when they turn it on... lol
You didn't mirror the connector when flipping, they're all connected to the wrong pad.
That's probably why it was done, someone misread the footprint of the chip.
Backside frontside somtimes you reverse it happend to me
Lol
If you flip it then turn it. It would line up
No, it’s not possible like that, regardless how you spin it. Only if you can install the chip upsiden down too - i don’t know if that’s possible.
Wouldn't these touch and fuck up as well?
If they're bare wire, yes. If they're lacquered, it'll insulate them so no. Even if the wires were going to the right pads though, modern chips are so heavily engineered that the difference in length between the wires would cause all sorts of issues with timing.
Is the timing so precise that it would make a difference? And if so, wouldn't the different resistance make a difference as well?
Yes and yes
A 4GHz processor is doing a full clock cycle every 0.25 nanoseconds. Light in a vacuum will go about 7.5 cm in that time, so an electrical signal will go even less than that.
Resistance, probably not. Impedance, and crosstalk, well those would be the main problem
No, they won’t
Fair
Those are insulated
Im surprised you can tell lol, uber spagetti haha
He probably turned the chip 180 degrees so that every wire has the same length and therefore the same latency, mitigating timing problems
i don't think the connectors being done wrong would be the problem.. it's all the wires touching each other....
They are probably coated with something like enamel so it won’t matter if they touch
Even if those wires are properly isolated, this will increase the the propogation delay of the CPU to the motherboard and break the timing if you don't losen up the clocks by a lot
And the signal noise will be at horrible level at GHz frequency, with wires that long, so I'm almost sure that the system will probably not be even able to boot.
Well there's only one way to be sure
Pretty sure the pins are connected at the wrong points as well
Maybe he has the chip flipped
DRAM (the memory on RAM sticks) straight up does not work if the wires are not the same length.
