Nvidia GTX 780ti nouveau re-clocking is not right

Hello
Last month, Phoronix posted about kepler reclocking working sort of without any lock ups at 0f state in linux 4.4. So I gave a try.
It seems, that in my case only memory clock speed gets set, core clock speed stays at ~300MHz even though for Michael 780ti re-clocked just fine. Could this be a brand specific issue? I am running Gigabyte GTX 780TI Windforce edition. I leave outputs for some commands.

dmesg:

[  183.703396] nouveau 0000:02:00.0: clk: failed to raise voltage: -22
[  183.703399] nouveau 0000:02:00.0: clk: error setting pstate 3: -22

cat /sys/class/drm/card0/device/pstate:

07: core 324 MHz memory 648 MHz
0a: core 324-1202 MHz memory 1620 MHz
0d: core 549-1346 MHz memory 7000 MHz
0f: core 549-1346 MHz memory 7000 MHz AC DC *
AC: core 324 MHz memory 6999 MHz

Glxgrears before - 7525.725 FPS, after reclocking - 8583.938 FPS.

Earlier, I've tried re-clocking to different states, but there wasn't a single one to change the core speed.

Is there a way to fix this issue?
Thanks in advance.
