Yes Tesla P4 is working, but if you want to get max performance of it, you have to tweak the Fan speed of the server with IPMItool. Because I am currently using btcrecover I am using 70% of the GPU capability with this software I set the minimum speed of the fans at 30% and the GPU steady temperature is 55.2C Now I am going to push it to its maximum capacity and the maximum noise level of the server, that my neighbors can handle  So, yes it is working
