recommend using the eVc
tool. Save yourself the time
and the headache associated
with all this.
Once you get around all of
that though, you’ll find that
overclocking the RX480 is
fairly straight forward and
simple. For some reason
AMD has limited the memory
clock frequency range here
and you’ll be stuck at 9GHz
or less, regardless of what
tool, firmware or whatever
hack. This is a limitation that
is hard to understand as the
memory is clearly capable
of reaching even higher
frequencies, but for some
reason past 9000MHz cannot
be set which is a real shame.
As for the core frequency,
you’ll find that the limits are

sub 1700MHz or 1700MHz.
This isn’t too bad given that
you’re looking at a GPU
that operates at 1,2656Mzh
nominally, but in this day and
age where GPUs are clocking
in well over 2GHz, it does
seem a little disappointing.
This is especially because
AMD is using a new node
process and we or at least
I had high hopes for it (No
it wasn’t because of the
dubious 1600Mhz air clock
rumours). Either way, you’ll
be hard pressed to not get to
1650MHz, which seems to be
about where most cards will
get to with LN2 cooling with
some going to 1700MHz.
The specific sample used
was capable of 1675MHz
and oddly enough this was
possible at only 1.293V (real
