gpu_freq = pll_freq / [even number] = 2440 / 4 = 610
Mine is 500. The math shows as 610.
You can't run gpu_freq at 610. v3d can only be overclocked to ~350MHz.
If you set core_freq=610, yes you will get a pll=2440.
If gpu_freq is not specified will aim for 250MHz using the largest even divisor of pllfreq.
In this case you will get 244MHz which will be fine.
You could specify gpu_freq=305 which would probably work okay, but I'd be suprised if you can see the difference between that and 244MHz.
