How to install nVIDIA GeForce Driver 345.20 on a 980 GTX?

I tried copying the nv_dispi.inf from the 353.30 drivers into the 345.20 folder but then it said missing files


how to modify the inf to allow me to install the older 345.20 driver onto my 980GTX? or would that not work at all since it's an older driver?

The 353.30 throttling is killing my performance.
