Buy a good processor or a good graphics card. For those who have never tried overclocking or have a little experience, it is likely that they will use it through official software. There is no problem, but if it comes to the hardware itself, you should think twice.
Recently, a foreign repair shop shared a tragic case of the RTX 4090. In order to obtain a 5FPS improvement, the user almost completely destroyed the originally good RTX 4090. Not only did the motherboard have scratches everywhere, but it was also soldered randomly, causing many short circuits.

The foreign YouTube channel NorthWestRepair will share some graphics card repair cases every once in a while. The latest Gigabyte RTX 4090 can be said to be very miserable on the entire card. The reason is that the user wants to modify the voltage, so that when the weather is good, the performance can be improved by 5fps.
NorthWestRepair said that when he got the RTX 4090, he immediately discovered some serious problems, such as broken labels and missing screws. However, after turning to the side, he also saw a very strange situation. The memory and GPU chips were covered with thick “adhesive” and could not be seen at all. He also speculated that there might not be a GPU chip inside:
Then he removed the back panel of the RTX 4090, and it was indeed very miserable inside. There were many rough amateur welding marks. Someone tried to do some welding in this area:
Next, he disassembled the cooling component. When he disassembled it, he immediately shouted “OMG”. This shows how miserable it was. This was probably the messiest application of thermal paste he had ever seen. It was everywhere. Fortunately, after wiping off the thermal paste, the GPU and memory chips were not damaged and were original parts. This also meant that his previous guess was wrong:
However, after checking the components on the supporting motherboard, such as inductors, short circuits were found:
Of course, the final step was to start repairing it. I have to say that I didn’t expect NorthWestRepair to be able to repair it in such a miserable condition. It’s really amazing.
As you can see from the video, he is constantly cleaning, testing, and re-soldering, and he continues to do this. He also said helplessly that almost no part of this RTX 4090 board is intact:
After the first round of repairs is completed, there are still more problems waiting to be solved. Things like broken or missing resistors and capacitors, or even broken PCB traces, all require precision soldering repairs:
Finally, he also replaced the memory controller and power supply MOSFET. After everything was completed, he conducted some tests, such as verifying whether the VRAM was functioning normally through the command line tool:
After confirming that there is no problem, enter the Windows system test, use FurMark and monitoring tools, both show that the RTX 4090 performs normally:
At the end of the video, NorthWestRepair also said that the repair is progressing smoothly, so the entire RTX 4090 will be assembled and put into the computer for more comprehensive testing. If everything is OK, then the repair video will end here.
If there is still a problem, a new video will be shared to explain it. I have not seen a new video so far, so it should be repaired successfully.
Although the card would be difficult to restore, he thought it would be fun and challenging.
