The Hidden Art of Graphics Card Memory Pad and Broken Trace Repair.

GPU Solutions

7,213 views

In this tutorial, I repair an RTX 3070 that was dropped and now suffers from artifacts due to broken memory pads. After identifying the faulty pads (A1, A0, B1), I lift all the GDDR6 memory modules, inspect them under the microscope, discard modules with too much damage, and reconstruct the broken pads on the PCB.

📌 WHAT YOU'LL LEARN IN THIS VIDEO:
• How to diagnose a dropped GPU with memory-related artifacts
• Locating broken pads using memory position mapping (A1, A0, B1, A2)
• Safely lifting GDDR6 memory modules with a BGA rework station
• Microscope inspection techniques for identifying cracked/broken pads
• Determining which memory modules are salvageable vs. needing replacement
• Step-by-step broken pad reconstruction on PCB
• Reballing reusable memory modules for reassembly

Finally, a clear demonstration of how to repair the ripped pads.
Thank you, it is like attending a virtual classroom.

@icedcoffee8561 1 year ago

Thanks for these videos! This is one of the best channels I've found for learning how to do these more advanced repairs.

how did the test go? everything end up working properly? would love to see before and after tests in the future!

@princekells2 1 year ago

We did replace the one caution vram it's okay and the other which shoes bad memory after replace the artifacts still shows what might be the issue

@xddarko 1 year ago

Lovely! Beginner question though: how did the customer know about the broken pads under the memory? Thanks!!

@danielroos5993 2 years ago

Thanks for the very helpful.video.:) I have a question though. Does the orientation of the vram chip matter?

@personalcomputerbuilds 2 years ago

what was the wire you are using to connect the broken pad thanks mate

@isabelgodwin5494 2 years ago

Last pad looks like you missed one I’m sure you fixed it later tho nice work

@miraalnilam9540 1 year ago

did you use uv solder mask to glue down the repair pads?

@kostashellas3339 1 year ago

Congratulations for your good skills and works . I have a question : I replaced in my rtx2080 the bad vram chip but the problem still remaining . C031 to c049 bits . Where is the problem in my gpu ?

@miraalnilam9540 1 year ago

where can i purchase the replacement pads?

@Gromyko91 1 year ago

Hello,
is it possible to add pads to the memory chip?

@kokodin5895 3 years ago

can you tell me how would you aproach repair when all memory chips on amd gpu would be bad and you would have a donor with a different brand and model memory?
in situation when the same vendor made this model with this memory you would probably hlash the bios nad move memory chips, but what if this particular memory was never used by the manufacturer of this gpu and there is no bios because this is a custom pcb version

is there a way to extract memory configuration from other amd gpu and patch it intoa bios pulled from a broken card? would this work or would there be more things to change?

@QuickFixKid 2 months ago

sooooo did it work?

@Happyguy60 2 years ago

great video my friend. but do i need a pre heater to do memory replacement on a graphics card myself?

@Lukasz703 2 years ago

Bro change solder mask or UV lamp. Try relife 3S green color for example. You will thank me later.

Speaking of solder lamp I’m using Mechanic uv lamp portable version . This duo cure solder mask within 10 seconds and it’s hard like my D!
