Matt how much power you gave to the Fury duo to achieve 1200 overclock?
Also how much is the maximum possible power mv to give to the Nano? Above 8mv i am scared. (Is watercooled thought)
Around +150mv, which on Pro Duo 1, Core 1, is around 1.275v.
Here are the clock states of both Pro Duo's.
Pro Duo 1 Core 1:
------[ GPU PStates List ]------
DPM0: GPUClock = 300 MHz, VID = 0.90000 V
DPM1: GPUClock = 508 MHz, VID = 0.95000 V
DPM2: GPUClock = 717 MHz, VID = 0.95600 V
DPM3: GPUClock = 874 MHz, VID = 1.03100 V
DPM4: GPUClock = 911 MHz, VID = 1.06800 V
DPM5: GPUClock = 944 MHz, VID = 1.10600 V
DPM6: GPUClock = 974 MHz, VID = 1.14300 V
DPM7: GPUClock = 1000 MHz, VID = 1.17500 V
Pro Duo 1 Core 2:

DPM5: GPUClock = 944 MHz, VID = 1.14300 V
DPM6: GPUClock = 974 MHz, VID = 1.18700 V
DPM7: GPUClock = 1000 MHz, VID = 1.21800 V

The first core on the Radeon Pro Duo's usually has a low default voltage, which makes it more capable to benefit from higher voltages. My second Pro Duo, although not as a good a clocker as my first, can reach similar clock speeds. They are typically held back a little by core two, which requires more voltage but they still clock higher than all of my FuryX's. In summary, i can not add as much voltage to Core 2 of both GPUs before the cards become unstable, but Core 1 of both GPUs can take decent amounts of voltage. I tend to have individual voltage settings for each Core at stock (undervolted) and overclocked for benchmarks.
I run them stock when gaming though as if the game supports CrossFire they chug out silly amounts of FPS which means i am way above the FreeSync range at 4k.
