i was trying to lower gpu and Memory clock but 3080ti FE still crashing. I have second GPU 1080TI and that one doesnt crash but it takes twice longer for it to do a frame.
Also compressing Video projects doenst crash
I found some topic that 3000 series had problems too. heres the link
UPDATE1
I installed NVIDIA STUDIO DRIVER 462.65 and so far 1100 frames done without crashing
UPDATE2
471.41-NVIDIA STUDIO DRIVER doesnt crash the process and see Both GPUS
