The recent U.S. government restrictions on AI hardware exports to China have significantly impacted several key semiconductor players, including NVIDIA, AMD, and Intel, restricting them from selling high-performance AI chips to Chinese land. This ban has notably affected NVIDIA's GeForce RTX 4090 ga...
we’ve seen some people modding cards to clamshell mode, apparently there is nothing burned into the core itself that determines whether it’s a quadro or a 4090, or whether a 4090 should have 24GB or 48GB, just a resistor array on the PCB itself. So if you resolder it onto a new PCB with twice the RAM chips, you can make it a “4090 48GB”, or even make it into a quadro.

this has been around for a while, I remember people doing this to turn 780s into titans/780 tis into titan black, but normally they weren’t adding more RAM capacity, just trying to get the ECC working and stuff, they’d just mod a couple resistors and boom it reports as quadro.
