Result of dmesg
When I attempt to reclock my ASUS GeForce GTX650 card, I manage to raise the clock speed of the RAM successfully, but the core clock speed does not change. I have attached my vbios.rom and dmesg results.

do you get errors like
[10913.271270] nouveau E[ CLK][0000:01:00.0] failed to raise voltage: -22
[10913.271273] nouveau E[ CLK][0000:01:00.0] error setting pstate 1: -22
I get exactly those errors.
sorry for the late answer
but you could try out building nouveau from here:
branch: stable_reclocking_kepler_v5 (based upon linux 4.6)
this should fix those errors.
