Thank you **so** much for your insights into BGA rework! I myself have always wanted to pick up the skill but I've always been put off by a lack of understanding of the subject. Watching your content marked the first time i genuinely understood why things are done in a certain way instead of following seemingly arbitrary procedure and chasing random numbers for no clear reason, and feel like if i found myself Infront of a setup I could give it a shot instead of curling up in a corner shaking in fear :)
Thanks for your kind words, I’m happy my video was useful. The subject is still pretty obscure to me and more experimentation is needed. But I’m getting somewhere.
At 20:07, the weird characters you see are ANSI control codes that are shown because you pipe the output to "less". Either don't pipe to less (so your terminal will display them properly) or invoke less with "less -R" - which will display the characters in raw mode; so the terminal will interpret them properly.
Gotcha! I suspected that as once I opened the report.txt file and they were displayed correctly there. Thanks for that. The incorrect characters I see on the bank names and operation type is the corrupted RAM though? Thanks for watching!
@@tony359 The incorrect text in the first pass (before you replaced the chip) was indeed because of the hw issues. Thx for the video, I enjoy watching your repairing adventures!
Of course I didn't! To be honest with you, I just wanted to return the GPU and the Asus MoBo to my friend so I kind of "expedited" them! :) Thanks for watching!
Fantastic! Liked. I have an FX3000 AGP I want to replace RAM on. It posts but has garbled text, but do you think their Linux utility would work with it?
The issues you had with installing the drivers was probably because 391.35 came out 8 years after the GTX 480's release. Ussing the last officially supported drivers is not usably the best. Driver optimization for that card stopped 2-3 years after release. So more ideal drivers would be from 2012-2013.
Thank you. 391.35 are the last drivers supporting the 480 - and they worked on another windows installation, I think it’s shown at the end of the video. Thanks for watching!
NVidia cards are a little sneaky. The VCore supply is split, with one phase being fed by the PCI bus connector and the rest by the 6+2 power expansion connectors. The reason for this is that they want the card to be able to do some things, at least power on and display an error message, even without being properly wired up, and possibly do some diagnostics before drawing full power otherwise. Most people fail to wire up the power connectors when they install their first card, and the card wants to be so polite as to point them in the right direction. There is usually a bunch of detection circuitry that goes to the VRM control IC and then that outputs the insufficient-power signal to a GPIO pin in the GPU core. But i don't remember the symptoms when one of the heavy VRM phases fails open that you expect of this card. One possible symptom is that the card is stuck at low clocks. I don't know if drivers not launching is a valid possible symptom for that, i'm not sure, it obviously wasn't in this case and probably shouldn't be the first suspicion. So yeah because of the VRM topology, when you measure the current on the power expansion wires, you aren't even getting the whole VCore current, some of it still comes from the PCI edge connector, and VMem etc are from the edge connector as well. However the first thing that happens to all those 12V inputs both the edge connector and the expansion wires, it goes into big fat shunt resistors that are monitored by the GPU. So when you call up the power stats in Afterburner's RTSS or in GPU-Z or any such utility, you're actually getting precision measurements of the power that goes in including VRM losses and just about everything that's on the card, no need for your own current measurements. This is not the case for AMD cards, you can't really trust what those report.
What do you mean it's not retro? Soon it is going to be retro😂 The BGA shakes do seem to be getting a bit better compared to the first attempts you did. Recording it probably puts some extra pressure on you i presume? I know about similar driver installation issues after a driver failed to install correctly and the fix used to be installing an older version first followed by the newer version. But nvidia drivers can be a bit silly, recently upgraded from a 1070 to a 3080TI and updating the drivers just didnt work at all so had to do fresh windows installation.
Ahaha - no the ‘shakes’ will never improve! It’s like my life depends on that 😂 I think I tried a random older driver and that failed too. Weird but good to hear it’s not uncommon. Thanks for watching!
Indeed! I had some horrible copycat and it was awful: did not work and scratched the ICs I was cleaning. Superwick just works as you'd expect! Thanks Adrian! And thank you for watching!
Is there a similar program to diagnose the memory in the radeon 9800 video card? I have two cards that can display a 2d image, but one displays tiny artifacts in 3D games, and the other doesn't accept drivers :/
Hello - I am not too familiar with this type of programs myself. I understand that MATS works with AMD cards as well but I do not know if the 9800 is compatible. That said, try the one I tested in the video, it runs under Windows and it should be manufacturer-agnostic! :) Obviously MATS is a necessity when you do NOT have a video output but if your system gets into Windows, then it's worth a try. Thanks for watching!
I know that you are no beginner, but I feel compelled to ask - regarding GPU temperatures, did you use thermopads of proper thickness? It is common mistake to use too fat thermopads and that makes a gap between heatsink and GPU.
Feedback is always welcome and I’m always learning! I think so. I used 1mm and I compared with the ones I removed and were identical. Thanks for watching!
Oh - also remember the heatsink is NOT part of the plate with the thermal pads. It's a separate piece. So even with incorrect pads, the heatsink would still sit on the GPU as expected!

Watching those solder balls suddenly snap into place was soooo satisfying. Informative as always. Thanks Tony.
isn't it? Indeed very satisfying! Thanks for watching!
I wish I had these repair skills, then I could revive my 8800GTS and breathe new life into my retro XP machine.
A nice, fun experiment and it's all good experience.
Thanks Ted! The fact that this time I didn’t incinerate the board while trying is a massive improvement indeed!

@@ThanassisTsiodras Thank you for your kind words! :)
Great video. I wanted to learn how to do reballing and I have some boards which
I can use to practice but I still don't have a time to do this.
I hope I helped a bit! Take your time and don't rush is my advice :) Thanks for watching!
great video, i was hoping you didn't forget about this videocard. cheers
Of course I didn't! To be honest with you, I just wanted to return the GPU and the Asus MoBo to my friend so I kind of "expedited" them! :) Thanks for watching!
Nice one, I have a few old GC's I would like to revive..
This was an "easy" one... I hope you have some easy ones too! Thanks for watching!
Fantastic! Liked. I have an FX3000 AGP I want to replace RAM on. It posts but has garbled text, but do you think their Linux utility would work with it?
I don’t think so to be honest, my 480 is barely recognised, MODS doesn’t work, only MATS. You can try though. Thanks for watching!
Good job!
Thank you!
