you have to use a near lauch date driver or have your linux-fu leveled up enough to create virtual machines with passed through hardware
for windows, first DDU all Nvidia drivers, then, install the tesla driver, then install, but not clean install the GeForce driver
alternatively there is a bit newer studio driver
there are newer drivers the k40 can use but for best compatibility, use the same version
keep in mind the k40 has a really old cuda version that isn’t supported by stable diffusion
and
the 3090 received a driver update that prevented itself from comiting sudoku
remember that amazon game that killed cards, yeah that was a driver update that fixed that
please please consider using at least maxwell cards, m40 can be had cheap and you get a much more newer driver
sincerly the guy that made this thread
