To my knowledge, the memory speed is still limited to 1250 instead of reaching
its maximum speed of 1300; the same thing goes for the core clock. I'll need to
have a look at the code, but the last time I had a look, we were still calling
btc_get_max_clock_from_voltage_dependency_table(), which was limiting the speed
to the reference values.
If I have time, I'll look at the code tonight and add some code to print values
that would be limited by btc_get_max_clock_from_voltage_dependency_table().
Other than this limitation, I have mostly no problem with my Cayman GPU.
