Hi, I am just tech savy individual, who decided to buy server and GPU RTX 4090 with broken PCIe holder, that is my first PC like system and first GPU I am planning to upgrade it to 48gb vRAM for LLM and later AI training, during upgrade PCB will be replaced, so I want to sest the card, if Its core and vRAM chips are working and schematics will help me figure it out. I had experience in repairing laptops 10y ago, but then I moved on web software development and I got to point, when I wanted my own server to play with and later develop some AI agents. So here I am, back to exciting field of HW.
