    mhh, I would expect more here sadly :/ this is like no improvement at all. you should check other stuff and so on. Usually +50% more perf should be the normal case compared to 0a

      I know that antichamber gets boosted as hell with higher memory clock though

        The last reports on the IRC logs I read about the GTX 760 Phantom also weren't reporting success with the reclocking above 0a

        Code:
        [ 1851.011306] nouveau 0000:01:00.0: clk: failed to raise voltage: -22
        [ 1851.011308] nouveau 0000:01:00.0: clk: error setting pstate 2: -22
        [ 1870.724161] nouveau 0000:01:00.0: clk: failed to raise voltage: -22
        [ 1870.724170] nouveau 0000:01:00.0: clk: error setting pstate 2: -22

        [ 1992.987729] nouveau 0000:01:00.0: clk: error setting pstate 3: -22
        Bummer, should have gone with a normally-clocked card
